Special Issue Information

Dear Colleagues,

Gestational diabetes mellitus (GDM) affects up to 15 to 18% of pregnancies and is associated with risks to both mother and child. Consequently, GDM is one of the most important metabolic complications during pregnancy. The benefits of therapies aiming to reduce glucose levels in GDM pregnancies are well-established. Nonetheless, several critical research questions remain unresolved: Firstly, the Hyperglycemia and Adverse Pregnancy Outcomes (HAPO) Study indicated a direct association between maternal glucose concentrations during a 75g oral glucose tolerance test, conducted between the 24th and 32nd weeks of gestation, and adverse perinatal outcomes. It is, however, an ongoing debate regarding whether earlier testing and treatment (before 24 weeks of gestation) could diminish perinatal complications. Secondly, the frequent co-occurrence of fetal overgrowth and maternal obesity may be partially independent from maternal hyperglycemia. This phenomenon is likely driven by a higher degree of maternal insulin resistance in obese mothers; however, research in this area is limited. Thirdly, GDM presents a complex challenge in clinical management due to its phenotypic heterogeneity. This heterogeneity of GDM needs to be addressed with more detail to provide individualized treatment strategies. These research gaps should be addressed by this Special Issue.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Objectives: Gestational diabetes mellitus (GDM) is associated with an increased risk of both neonatal and maternal morbidity. The aim of this retrospective study was to evaluate the frequency of perinatal complications due to GDM in the Department of Neonatology at the Medical University of Wroclaw, Poland, considering the treatment of GDM—diet and physical activity versus insulin therapy. The influence of maternal comorbidities and the COVID-19 pandemic on pregnancy outcomes was assessed. Methods: A retrospective analysis of medical records was conducted. Statistics were calculated using a range of methods, with p < 0.05 considered significant. A sample of n = 625 mothers with n = 646 newborns were included in this study. Results: The newborns of insulin-treated mothers had cardiovascular defects more often (p < 0.05). A higher prevalence of vaginal infections was found in the diet-treated mothers (p < 0.05), while insulin-treated mothers had a higher prevalence of pregnancy-induced hypertension, pregnancy-induced hypothyroidism and obesity (p < 0.05). The mode of delivery, maternal age and maternal pregnancy-induced hypertension, obesity and cholestasis were found to influence neonatal outcomes (p < 0.05). Conclusions: The maternal management of GDM is not the main determinant of pregnancy outcomes, which might be affected by other maternal comorbidities. Effective initiatives are needed to control GDM, support breastfeeding and prevent adverse pregnancy outcomes Full article

Background/Objectives: Recently, it was reported that glucose variability (GV) calculated using the 75 g oral glucose tolerance test (OGTT) is associated with adverse perinatal outcomes. However, its role in gestational diabetes mellitus (GDM) remains unclear. We investigated the association between GV and insulin parameters in Japanese women diagnosed with GDM after 24 weeks of gestation (late GDM). Methods: A total of 280 mothers with late GDM cared for at Keio University Hospital were included in this study. Using 75 g OGTT, the initial increase and subsequent decrease were calculated as the GV. Results: The initial increase was significantly positively associated with 1 h plasma glucose level (PG) and 2 h PG with 75 g OGTT (p < 0.001), but fasting PG, insulinogenic index (IGI), and homeostasis model assessment—insulin resistance were negatively associated with the initial increase (all p < 0.001). The subsequent decrease was significantly positively correlated with 1 h PG (p < 0.001) but negatively correlated with 2 h PG (p < 0.001), IGI (p = 0.009), and the whole-body insulin sensitivity index derived from the OGTT (p = 0.02). Insulin Secretion-Sensitivity Index-2 was not associated with an initial increase or subsequent decrease. Conclusions: Since the initial increase might reflect insulin secretion and the subsequent decrease might reflect insulin sensitivity in Japanese women with late GDM, GV could alter several insulin parameters. Further studies are required to investigate the usefulness of GV in the management of GDM. Full article
