RESUMEN
OBJECTIVE: Gestational diabetes mellitus (GDM) is associated with several adverse maternal and neonatal outcomes. Previous studies reported a link between altered sleep and risk of GDM. This systematic review aims to collate evidence on the association between impaired sleep quality and duration, and the risk of GDM. METHODS: PubMed, Embase, Web of Science, and Scopus databases were searched up to January 20, 2024. Studies reporting the association between impaired sleep quality and duration and risk of GDM were included. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Random-effects meta-analysis was performed, and the results were reported as hazard ratio (HR) with 95% confidence interval (CI). RESULTS: 19 studies were included. Meta-analysis revealed a significant increase in the risk of GDM in pregnant women with poor sleep quality (i.e. <5 PSQI) (HR: 1.50, 95% CI: 1.26 - 1.78, p < .001). Sleep duration of <7 h (HR: 1.56, 95% CI.: 1.20 - 2.01, p < .001), and >8 h (HR: 2.32, 95% CI.: 1.19 - 4.50, p = .01) were also associated with a significantly higher incidence of GDM. CONCLUSION: Sleep quality and duration emerge as critical risk factors of GDM. Healthcare practitioners should consider targeted interventions to improve sleep hygiene as a potential measure for GDM prevention.

Women with a history of Gestational diabetes mellitus (GDM) have a high risk of developing Type 2 diabetes mellitus (T2DM) in their future life. Lifestyle interventions are known to reduce this progression. The success of a lifestyle intervention mainly depends on its feasibility. Therefore, this study aimed to evaluate the feasibility of a lifestyle intervention programme aimed to attenuate the development of T2DM in mothers with a history of GDM. This qualitative phenomenological study was carried out in selected Medical offices of Health (MOH) areas in Sri Lanka. Postpartum mothers with a history of GDM who have undergone a comprehensive, supervised lifestyle intervention program for 1 year, their family members, and public health midwives (PHM) were recruited for this study. Focus group discussions (FGD) were carried out with mothers and PHM while In-depth interviews (IDI) were conducted with family members. Framework analysis was used for the analysis of data. A total of 94 participants (45 mothers, 40 healthcare workers, and 9 family members) participated in FGDs and IDIs to provide feedback regarding the lifestyle intervention. Sixteen sub-themes emerged under the following four domains; (1) Feelings and experiences about the lifestyle intervention programme for postpartum mothers with a history of GDM (2) Facilitating factors (3) Barriers to implementation and (4) Suggestions for improvement. Spouse support and continued follow-up were major facilitating factors. The negative influence of healthcare workers was identified as a major barrier to appropriate implementation. All participants suggested introducing continuing education programmes to healthcare workers to update their knowledge. The spouse's support and follow-ups played a pivotal role in terms of the success of the programme. Enhancing awareness of the healthcare workers is also essential to enhance the effectiveness of the programme. It is imperative to introduce a formal intervention programme for the postpartum management of mothers with a history of GDM. It is recommended that the GDM mothers should be followed up in the postpartum period and this should be included in the national postpartum care guidelines.

OBJECTIVE: To understand the perspectives of key informant experts regarding the relationship between food insecurity and gestational diabetes mellitus risk reduction behaviors among young American Indian and Alaska Native females. METHODS: Participants were adult key informants with expertise in food/nutrition and health within Tribal communities (N = 58) across the US. Data were collected through 1:1 interviews using a semistructured moderator guide and analyzed using thematic content analysis methods. RESULTS: Three themes included (1) diet and nutrition habits are formed through intergenerational food preferences and are driven by lasting implications of colonization; (2) young people are influenced by what their peers eat and the food environment, including outside of the home; and (3) the methods used to understand household food insecurity and nutrition habits in the parent study were likely limited. CONCLUSIONS AND IMPLICATIONS: Findings provide guidance as to where nutrition education and interventions may best support young Native females.

BACKGROUND: Observational studies have revealed associations between maternal lipid metabolites and gestational diabetes mellitus (GDM). However, whether these associations are causal remain uncertain. OBJECTIVE: To evaluate the causal relationship between lipid metabolites and GDM. METHODS: A two-sample Mendelian randomization (MR) analysis was performed based on summary statistics. Sensitivity analyses, validation analyses and reverse MR analyses were conducted to assess the robustness of the MR results. Additionally, a phenome-wide MR (Phe-MR) analysis was performed to evaluate potential side effects of the targeted lipid metabolites. RESULTS: A total of 295 lipid metabolites were included in this study, 29 of them had three or more instrumental variables (IVs) suitable for sensitivity analyses. The ratio of triglycerides to phosphoglycerides (TG_by_PG) was identified as a potential causal biomarker for GDM (inverse variance weighted (IVW) estimate: odds ratio (OR) = 2.147, 95% confidential interval (95% CI) 1.415-3.257, P = 3.26e-4), which was confirmed by validation and reverse MR results. Two other lipid metabolites, palmitoyl sphingomyelin (d18:1/16:0) (PSM(d18:1/16:0)) (IVW estimate: OR = 0.747, 95% CI 0.583-0.956, P = 0.021) and triglycerides in very small very low-density lipoprotein (XS_VLDL_TG) (IVW estimate: OR = 2.948, 95% CI 1.197-5.215, P = 0.015), were identified as suggestive potential biomarkers for GDM using a conventional cut-off P-value of 0.05. Phe-MR results indicated that lowering TG_by_PG had detrimental effects on two diseases but advantageous effects on the other 13 diseases. CONCLUSION: Genetically predicted elevated TG_by_PG are causally associated with an increased risk of GDM. Side-effect profiles indicate that TG_by_PG might be a target for GDM prevention, though caution is advised due to potential adverse effects on other conditions.

Background: The infant gut microbiome's establishment is pivotal for health and immune development. Understanding it unveils insights into growth, development, and maternal microbial interactions. Research often emphasizes gut bacteria, neglecting the phageome. Methods: To investigate the influence of geographic or maternal factors (mode of delivery, mode of breastfeeding, gestational diabetes mellitus) on the gut microbiota and phages of newborns, we collected fecal samples from 34 pairs of mothers and their infants within 24 hours of delivery from three regions (9 pairs from Enshi, 7 pairs from Hohhot, and 18 pairs from Hulunbuir) using sterile containers. Gut microbiota analysis by Shotgun sequencing was subsequently performed. Results: Our results showed that geographic location affects maternal gut microbiology (P < 0.05), while the effect on infant gut microbiology was not significant (P = 0.184). Among the maternal factors, mode of delivery had a significant (P < 0.05) effect on the newborn. Specific bacteria (e.g., Bacteroides, Escherichia spp., Phocaeicola vulgatus, Escherichia coli, Staphylococcus hominis, Veillonella spp.), predicted active metabolites, and bacteriophage vOTUs varied with delivery mode. Phocaeicola vulgatus significantly correlated with some metabolites and bacteriophages in the early infant gut (P < 0.05). In the GD group, a strong negative correlation of phage diversity between mother and infants was observed (R = -0.58, P=0.04). Conclusion: In conclusion, neonatal early gut microbiome (including bacteria and bacteriophages) colonization is profoundly affected by the mode of delivery, and maternal gestational diabetes mellitus. The key bacteria may interact with bacteriophages to influence the levels of specific metabolites. Our study provides new evidence for the study of the infant microbiome, fills a gap in the analysis of the infant gut microbiota regarding the virome, and emphasizes the importance of maternal health for the infant initial gut virome.

INTRODUCTION: Considering the relationship between Gestational Diabetes Mellitus and maternal and perinatal adverse outcomes, it's pertinent to investigate whether this diagnosis is a predictor of fear of childbirth. As there is little data about the fear of childbirth in Brazil, it´s necessary to understand better the population, and this way the authors can identify factors that influence this fear as well as propose public health policies to treat it. OBJECTIVE: The main goal was to compare the prevalence of fear of childbirth between the groups of low-risk pregnancy and gestational diabetes mellitus. MATERIAL AND METHODS: In this cohort study, the sample consisted of 319 patients divided into low-risk pregnancy group (n = 152) and gestational diabetes mellitus group (n = 167). Patients have undergone a semi-structured interview with epidemiological, obstetric, and anthropometric data and the main cause of fear of childbirth. In addition, the patients have marked an "X" on the scale into the Fear of Birth Scale to describe their fear. After delivery, data have been collected through electronic medical records. RESULTS: The prevalence of fear of childbirth found was higher for the gestational diabetes mellitus group (46.05%) compared to the low-risk pregnancy group (34.73%) with a cutoff score ≥ 54. In the whole sample, the main cause of fear of childbirth (score ≥ 60) was the pain of labor and delivery (31.58%). CONCLUSIONS: The prevalence of fear of childbirth in the present study was greater than 30%, highlighting the relevance of implementing this assessment during prenatal care.

BACKGROUND: We investigated the impacts of tocolytic agents on maternal and neonatal blood glucose levels in women with gestational diabetes mellitus (GDM) who used tocolytics for preterm labor. METHODS: This multi-center, retrospective cohort study included women with GDM who were admitted for preterm labor from twelve hospitals in South Korea. We excluded women with multiple pregnancies, anomalies, overt DM diagnosed before pregnancy or 23 weeks of gestation, and women who received multiple tocolytics. The patients were divided according to the types of tocolytics; atosiban, ritodrine, and nifedipine group. We collected baseline maternal characteristics, pregnancy outcomes, maternal glucose levels during hospitalization, and neonatal glucose levels. We compared the frequency of maternal hyperglycemia and neonatal hypoglycemia among three groups. A multivariate logistic regression analysis was performed to evaluate the contributing factors to the occurrence of maternal hyperglycemia and neonatal hypoglycemia. RESULTS: A total of 128 women were included: 44 (34.4%), 51 (39.8%), and 33 (25.8%) women received atosiban, ritodrine, and nifedipine, respectively. Mean fasting blood glucose (FBG) (112.3, 109.6, and 89.5 mg/dL, P < 0.001) and 2-hour postprandial glucose (PPG2) levels (145.4, 148.3, and 116.5 mg/dL, P = 0.004) were significantly higher in atosiban and ritodrine group than those in nifedipine group. Even after adjusting for covariates including antenatal steroid use, gestational age at admission, and pre-pregnancy body mass index, there was an increased risk of high maternal mean FBG (≥ 95 mg/dL) and PPG2 (≥ 120 mg/dL) levels in the atosiban and ritodrine group than in nifedipine group. The atosiban and ritodrine groups are also at increased risk of neonatal hypoglycemia (< 47 mg/dL) compared to the nifedipine group with the odds ratio of 4.58 and 4.67, respectively (P < 0.05). CONCLUSION: There is an increased risk of maternal hyperglycemia and neonatal hypoglycemia in women with GDM using atosiban and ritodrine tocolytics for preterm labor compared to those using nifedipine.

PURPOSE OF REVIEW: Gestational diabetes mellitus (GDM) is one of the most common pregnancy complications worldwide and the prevalence is continuously rising globally. Importantly, GDM is not an isolated complication of pregnancy. Growing evidence suggests that individuals with GDM, compared to those without GDM, have an increased risk of subsequent type 2 diabetes (T2D) and cardiovascular diseases (CVD). Substantial racial and ethnic disparities exist in the risk of GDM. However, the role of race and ethnicity in the progression from GDM to T2D and CVD remains unclear. The purpose of the current review is to summarize recent research about GDM and its life-course impacts on cardiometabolic health, including 1) the peak time of developing T2D and CVD risks after GDM, 2) the racial and ethnic disparities in the risk cardiometabolic diseases after GDM, 3) the biological plausibility and underlying mechanisms, and 4) recommendations for screening and prevention of cardiometabolic diseases among individuals with GDM, collectively to provide an updated review to guide future research. RECENT FINDINGS: Growing evidence has indicated that individuals with GDM had greater risks of T2D (7.4 to 9.6 times), hypertension (78% higher), and CDV events (74% higher) after GDM than their non-GDM counterparts. More recently, a few studies also suggested that GDM could slightly increase the risk of mortality. Available evidence suggests that key CVD risk factors such as blood pressure, plasma glucose, and lipids levels are all elevated as early as < 1 year postpartum in individuals with GDM. The risk of T2D and hypertension is likely to reach a peak between 3-6 years after the index pregnancy with GDM compared to normal glycemia pregnancy. Cumulative evidence also suggests that the risk of cardiometabolic diseases including T2D, hypertension, and CVD events after GDM varies by race and ethnicity. However, whether the risk is higher in certain racial and ethnic groups and whether the pattern may vary by the postpartum cardiometabolic outcome of interest remain unclear. The underlying mechanisms linking GDM and subsequent T2D and CVD are complex, often involving multiple pathways and their interactions, with the specific mechanisms varying by individuals of different racial and ethnic backgrounds. Diabetes and CVD risk screening among individuals with GDM should be initiated early during postpartum and continue, if possible, frequently. Unfortunately, adherence to postpartum glucose testing with either obstetrician or primary care providers remained poor among individuals with GDM. A life-course perspective may provide critical information to address clinical and public health gaps in postpartum screening and interventions for preventing T2D and CVD risks in individuals with GDM. Future research investigating the racial- and ethnic-specific risk of progression from GDM to cardiometabolic diseases and the role of multi-domain factors including lifestyle, biological, and socio-contextual factors are warranted to inform tailored and culture-appropriate interventions for high-risk subpopulations. Further, examining the barriers to postpartum glucose testing among individuals with GDM is crucial for the effective prevention of cardiometabolic diseases and for enhancing life-long health.

Gestational diabetes mellitus (GDM) adversely affects offspring glucose homeostasis and risk of developing obesity. Here, we examined the association between glycemia in pregnant women with overweight or obesity without GDM and offspring metabolic health. Maternal fasting glucose concentrations and glucose 2-h after an oral glucose tolerance test (OGTT) were measured in 208 women with a pre-pregnancy body mass index (BMI) of 28-45 kg/m2 without GDM. Offspring outcomes were collected at birth, 3, and 5 years of age. Linear mixed models with time as fixed factor and subject ID as random effects were used for analysis. No associations were found between maternal fasting or 2-h glucose concentrations with offspring glucose and insulin concentrations from birth to 5 years of age. However, maternal fasting glucose in GW 28 and 36, and 2-h OGTT glucose in GW 28 were positively associated with C-peptide concentration at birth. Maternal fasting glucose concentrations in GW 28 and 36 were positively associated with weight-for-length, and maternal fasting glucose in GW 36 was associated with BMI z-score at birth. In summary, blood glucose in pregnant women with overweight or obesity is positively associated with offspring C-peptide concentration, weight-for-length, and BMI z-score at birth, even in the absence of GDM.

Gestational diabetes mellitus (GDM) represents a prevalent complication during pregnancy, exerting both short-term and long-term impacts on maternal and offspring health. This review offers a comprehensive outline of DNA methylation modifications observed in various maternal and offspring tissues affected by GDM, emphasizing the intricate interplay between DNA methylation dynamics, gene expression, and the pathogenesis of GDM. Furthermore, it explores the influence of environmental pollutants, maternal nutritional supplementation, and prenatal gut microbiota on GDM development through alterations in DNA methylation profiles. Additionally, this review summarizes recent advancements in DNA methylation-based diagnostics and predictive models in early GDM detection and risk assessment for subsequent type 2 diabetes. These insights contribute significantly to our understanding of the epigenetic mechanisms underlying GDM development, thereby enhancing maternal and fetal health outcomes and advocating further efforts in this field.

This review discusses the pathophysiology of diabetes in pregnancy in relation to the placental function. We review the potential use of hydroxychloroquine in improving pregnancy outcomes affected by diabetes. The review focuses on the mechanism of action of hydroxychloroquine and its potential effects on diabetes. There are several pathways in which hydroxychloroquine mediates its effects: through the inflammasome complex, inflammatory cytokines, oxidative stress, modulatory effects, and antihyperglycemic effects. As a safe drug to be used in pregnancy, it is worth exploring the possible use hydroxychloroquine as an adjunct treatment to the current therapy of diabetes in pregnancy.

This study estimates gestational diabetes mellitus prevalence in Brazil. A systematic review was conducted with articles published between 2010 and 2021 on the PubMed, Scopus, Google Scholar, SciELO, LILACS and Virtual Health Library databases, as well as gray literature. Data were extracted using a standardized instrument together with the risk of bias assessment tool proposed by Hoy et al. A meta-analysis with robust variance and random effects was developed. Heterogeneity was verified using I2 and publication bias was assessed using funnel plot and Egger's test. Prevalence according to risk of bias, diagnostic criteria and country's regions was determined by subgroup analyses. A total of 32 studies were included, representing 21,942 women. gestational diabetes mellitus pooled prevalence was 14% (95%CI: 11.0; 16.0), considerably higher than estimates from previous studies. Regarding risk of bias, studies with low, medium, and high risk showed a pooled prevalence of 12%, 14% and 14%, respectively. Overall GRADE certainty of evidence rating was low. Most studies used the International Association of Diabetes in Pregnancy Study Group (IADPSG) criteria or the adapted IADPSG, showing a pooled prevalence of 15% and 14%, respectively. As for region, the pooled prevalence was higher in the Southeast (14%) and lower in the Central-West (9%). This is the first systematic review to provide evidence on gestational diabetes mellitus prevalence at a national level and to demonstrate considerable heterogeneity among articles and the influence of region, diagnostic criteria and study quality on the referred indicator.

BACKGROUND: This study aimed to investigate the effects of hemoglobin A1c (HbA1c), fasting blood glucose (FBG), 2-hours postprandial blood glucose (2hPBG), and fasting insulin (FINS) levels on pregnancy outcomes and their predictive value in patients with gestational diabetes mellitus (GDM). METHODS: A total of 109 pregnant women with GDM (GDM group) were included and assayed for serum FBG, 2hPBG, HbA1c, and FINS levels. The incidence of adverse pregnancy outcomes was recorded. GDM patients were divided into the poor pregnancy outcome group and the favorable pregnancy outcome group and analyzed for HbA1c, FBG, 2hPBG, and FINS. The predictive value of serum index combined detection on GDM pregnancy outcome was assessed, and the effect of serum indices on pregnancy outcome was evaluated in GDM patients with logistic regression. RESULTS: In the GDM group, there were 8 cases of premature membranes breaking (7.34%), 6 cases of premature delivery (5.50%), 3 cases of hyperamniotic fluid (2.75%), 2 cases of neonatal asphyxia (1.83%), 5 cases of fetal growth restriction (4.59%), and 3 cases of low-birth-weight infants (2.75%). The total incidence of adverse preg-nancy outcomes was 24.77% (27/109). HbA1c, FBG, 2hPBG, and FINS in the poor pregnancy outcome group were higher than those in the favorable pregnancy outcome group. The AUC value of blood biochemical indicators combined detection in predicting pregnancy outcome in GDM patients was higher than of HbA1c, FBG, 2hPBG, and FINS alone detection. HbA1c ≥ 6.94%, FBG ≥ 7.18 mmol/L, 2hPBG ≥ 9.36 mmol/L, and FINS ≥ 13.07 U/L were the risk factors affecting pregnancy outcomes in GDM patients. CONCLUSIONS: The changes of HbA1c, FBG, 2hPBG, and FINS levels in GDM patients are associated with adverse pregnancy outcomes, and the combined detection of serum indicators has predictive value for pregnancy outcomes in GDM patients.

BACKGROUND: Diabetes in pregnancy is associated with short and long-term adverse health outcomes for mothers and babies. The condition disproportionately impacts Pacific, Maaori, and Indian pregnancies. Those with diabetes are offered intensive support during pregnancy, but in many centres, no additional support following birth beyond routine care. The aim of this study was to determine the postpartum needs for mothers and whaanau (family) impacted by diabetes in pregnancy, to inform co-design of a new service to improve metabolic and developmental outcomes for infants. METHODS: Pregnancies complicated by diabetes were identified using a local diabetes registry. Mothers with a diagnosis of GDM or T2DM and gave birth between January 2022 -June 2022 were eligible for the study. A total of 19 parents (18 mothers, 1 father) were interviewed. Participants primarily identified as Maaori (6), Pacific (6), Indian (3), Asian (2), and New Zealand European (2). Interviews took place between December 2022 and February 2023, between 5-13 months post-pregnancy. Interviews facilitated by an externally contracted local Pacific mother, with a professional background in social work were conducted using Koorero and Talanoa, Maaori and Pacific methods of qualitative data collection, to capture the lived experiences of participants. A multidisciplinary group reviewed and coded interview transcripts. Themes were presented back to participants and stakeholders for feedback and refinement. Four over-arching themes were illustrated with exemplar quotes. RESULTS: Four themes described the importance of 1) Finding a balance between what is "best practice" and what is best for me, my baby and my whaanau, 2) The need for individualised and culturally appropriate care, 3) Centrality of whaanau and family to the pregnancy and postpartum journey, 4) The pervasive negative impact of diabetes on taha hinegaro (well-being) beyond childbirth. CONCLUSION: People who are affected by diabetes in pregnancy have ongoing physical, psychological, and social needs. A holistic, whaanau-centred approach is required to ensure optimal health and well-being outcomes of mothers, infants and whaanau. The findings of this study will inform a new targeted model of care for infants and whaanau affected by diabetes in pregnancy.

BACKGROUND: The risk of developing type 2 diabetes mellitus (T2DM) is up to 50% among women with gestational diabetes mellitus (GDM). However, diabetes education during and after pregnancy is limited. To bridge this gap, our team developed four training modules on GDM for nurses and community health workers. This pilot study assesses changes in knowledge, self-efficacy for providing diabetes education, attitudes, and intentions to recommend diabetes prevention before and after training completion. METHODS: Interactive online modules were disseminated to clinical staff providing care for women with GDM in the United States. Optional pre- and post-training surveys were conducted to gauge the effectiveness of the modules. GDM knowledge (scoring 0-100) was evaluated with a 23 question assessment with total score and individual module scores reported [(# correct/# total)*100]. Self-efficacy for providing diabetes education (scoring 1-10) was evaluated with a 15-question survey and intention to recommend diabetes prevention (scoring 1-5) was assessed with an 8-item survey. Attitudes were assessed with three subscales of the Diabetes Attitude Scale (scoring 1-5). Changes in scores on each scale before and after training are reported using non-parametric Wilcoxon matched-pair signed rank tests. RESULTS: Eighty-two individuals completed baseline evaluation and 20 individuals accessed all modules and completed post-training assessments. Among those completing the training, improvement was noted in GDM knowledge [56.5 (16.0) v. 78.3 (22.0), p < 0.001], self-efficacy for providing diabetes education [6.60 (2.73) v. 9.33 (0.87), p < 0.001], attitudes toward the value of tight control [4.07 (0.79) v. 4.43 (0.86), p = 0.003], and intentions to recommend diabetes prevention measures [4.81 (0.63) v. 5.00 (0.00), p = 0.009)]. CONCLUSIONS: Completion of our interactive online modules improved knowledge, intention to recommend diabetes prevention, self-efficacy to provide diabetes education, and attitudes toward the value of tight control among individuals caring for women with GDM. TRIAL REGISTRATION: This study was registered at clinicaltrials.gov, identifier: NCT04474795.

BACKGROUND: Accumulating evidence shows that free fatty acids (FFA) are associated with gestational diabetes mellitus (GDM). However, most of the studies focus on a few specific types of FFA, such as α-linolenic acid (C18:3n3) and Arachidonic acid (C20:4n6) or a total level of FFA. OBJECTIVE: This study aimed to test the association between a variety of FFAs during the first trimester and the risk of GDM. METHODS: The participants came from the Zhoushan Pregnant Women Cohort (ZWPC). A 1:2 nested case-control study was conducted: fifty mothers with GDM were matched with 100 mothers without GDM by age, pre-pregnancy body mass index (BMI), month of oral glucose tolerance test (OGTT) and parity. Thirty-seven FFAs (including 17 saturated fatty acids (SFA), 8 monounsaturated fatty acids (MUFA), 10 polyunsaturated fatty acids (PUFA) and 2 trans fatty acids (TFA)) in maternal plasma during the first trimester were tested by Gas Chromatography-Mass Spectrometry (GC-MS). Conditional logistic regression models were performed to assess the associations of FFA with the risk of GDM. RESULTS: Nine FFAs were respectively associated with an increased risk of GDM (P < 0.05), and four FFAs were respectively associated with a decreased risk of GDM (P < 0.05). SFA risk score was associated with a greater risk of GDM (OR = 1.34, 95% CI: 1.12-1.60), as well as UFA risk score (OR = 1.26, 95% CI: 1.11-1.44), MUFA risk score (OR = 1.70, 95%CI: 1.27-2.26), PUFA risk score (OR = 1.32, 95%CI: 1.09-1.59) and TFA risk score (OR = 2.51, 95%CI: 1.23-5.13). Moreover, joint effects between different types of FFA risk scores on GDM were detected. For instance, compared with those with low risk scores of SFA and UFA, women with high risk scores of SFA and UFA had the highest risk of GDM (OR = 8.53, 95%CI: 2.41-30.24), while the Odds ratio in those with a low risk score of SFA and high risk score of UFA and those with a high risk score of SFA and low risk score of UFA was 6.37 (95%CI:1.33- 30.53) and 4.25 (95%CI: 0.97-18.70), respectively. CONCLUSION: Maternal FFAs during the first trimester were positively associated with the risk of GDM. Additionally, there were joint effects between FFAs on GDM risk. CONDENSATION: Elevated FFA levels in the first trimester increased the risk of GDM.

Gestational diabetes mellitus (GDM) is a common disease during pregnancy that has adverse effects on both the mother and fetus. There are currently rare researches on the effect of vitamin supplementation on GDM pregnant mother and their offspring on animal and cell levels systematically. This work supplemented the GDM pregnant mouse model with vitamin D and found that vitamin D can effectively alleviate the hyperglycemia in GDM pregnant mice, increase blood insulin and adiponectin concentrations, and improve GTT and ITT in pregnant mice. In addition, vitamin D can reduce the incidence of death and high birth weight of offspring caused by GDM. The offspring of GDM pregnant mice had higher blood glucose levels in the first 5 weeks after birth compared to the normal group, and then returned to normal levels. Vitamin D can alleviate abnormal glucose metabolism in newborn mice. The therapeutic effect exhibited by vitamin D may be due to their anti-inflammatory effects, as vitamin D supplementation significantly reduces the levels of TFN-?, MCP-1, IL-1? and IL-8 in the blood. Vitamin D also regulates liver lipid metabolism, resulting in a decrease in liver lipid accumulation and a decrease in blood triglycerides (TG) and cholesterol (CHO). The results of this study demonstrate that vitamin D supplementation can serve as an effective treatment strategy for alleviating GDM symptoms. Keywords: Gestational diabetes mellitus, Vitamin D, Glucose metabolism, Anti-inflammatory.

INTRODUCTION: The human gut microbiota is associated with gestational diabetes mellitus (GDM), which imposes a risk of developing long-term health problems for mother and child. Most studies on GDM and microbiota have been cross-sectional, which makes it difficult to make any conclusions on causality. Furthermore, it is important to assess if a dysbiotic microbiota is passed from the mother to the child, and then being at risk of developing metabolic health problems later in life. The DANish Maternal and Offspring Microbiome study aims to identify gut microbiota-related factors involved in metabolic dysfunction in women with GDM and their offspring. Importantly, the study design allows for early detection of biological changes associated with later development of metabolic disease. This could provide us with unique tools to support early diagnosis or implement preventative measures. METHODS AND ANALYSIS: Pregnant women are included in the study after the 11-14 weeks' prenatal ultrasound scan and followed throughout pregnancy with enrolment of the offspring at birth. 202 women and 112 children have been included from North Denmark Regional Hospital and Aalborg University Hospital in Denmark. Mother and child are followed until the children reach the age of 5 years. From the mother, we collect faeces, urine, blood, saliva, vaginal fluid and breast milk samples, in addition to faeces and a blood sample from the child. Microbiota composition in biological samples will be analysed using 16S rRNA gene sequencing and compared with demographic and clinical data from medical charts, registers and questionnaires. Sample and data collection will continue until July 2028. ETHICS AND DISSEMINATION: The study protocol has been approved by the North Denmark Region Committee on Health Research Ethics (N20190007). Written informed consent is obtained from all participants prior to study participation. Study results will be published in international peer-reviewed journals and presented at international conferences. The results will also be presented to the funders of the study and study participants.

OBJECTIVE: To investigate relationships between prognostic nutritional index (PNI) during pregnancy and risk of all-cause mortality (ACM) and cardiovascular disease (CVD) mortality in persons with gestational diabetes mellitus (GDM). METHODS: A cross-sectional study was conducted using NHANES data from 2007 to 2018, and weighted Cox regression models were established. Restricted cubic spline analysis was used to unveil associations of PNI with risk of ACM and CVD mortalities in individuals with GDM. Receiver operating characteristic curve was employed for determination of threshold value for association of PNI with mortality. Sensitivity analysis was performed to verify the stability of the results. RESULTS: 734 GDM individuals and 7987 non-GDM individuals were included in this study. In GDM population, after adjusting for different categorical variables, PNI was significantly negatively correlated with ACM risk. Subgroup analysis showed that among GDM populations with no physical activity, moderate physical activity, parity of 1 or 2, negative correlation between PNI and risk of ACM was stronger than other subgroups. Sensitivity analysis results showed stable negative correlations between PNI and ACM and CVD mortality of total population, and between PNI and ACM of GDM. CONCLUSION: In individuals with GDM, PNI was negatively correlated with ACM risk, especially in populations with no physical activity, moderate physical activity, and parity of 1 or 2. PNI = 50.75 may be an effective threshold affecting ACM risk in GDM, which may help in risk assessment and timely intervention for individuals with GDM.

BACKGROUND: It remains unclear which early gestational biomarkers can be used in predicting later development of gestational diabetes mellitus (GDM). We sought to identify the optimal combination of early gestational biomarkers in predicting GDM in machine learning (ML) models. METHODS: This was a nested case-control study including 100 pairs of GDM and euglycemic (control) pregnancies in the Early Life Plan cohort in Shanghai, China. High sensitivity C reactive protein, sex hormone binding globulin, insulin-like growth factor I, IGF binding protein 2 (IGFBP-2), total and high molecular weight adiponectin and glycosylated fibronectin concentrations were measured in serum samples at 11-14 weeks of gestation. Routine first-trimester blood test biomarkers included fasting plasma glucose (FPG), serum lipids and thyroid hormones. Five ML models [stepwise logistic regression, least absolute shrinkage and selection operator (LASSO), random forest, support vector machine and k-nearest neighbor] were employed to predict GDM. The study subjects were randomly split into two sets for model development (training set, n = 70 GDM/control pairs) and validation (testing set: n = 30 GDM/control pairs). Model performance was evaluated by the area under the curve (AUC) in receiver operating characteristics. RESULTS: FPG and IGFBP-2 were consistently selected as predictors of GDM in all ML models. The random forest model including FPG and IGFBP-2 performed the best (AUC 0.80, accuracy 0.72, sensitivity 0.87, specificity 0.57). Adding more predictors did not improve the discriminant power. CONCLUSION: The combination of FPG and IGFBP-2 at early gestation (11-14 weeks) could predict later development of GDM with moderate discriminant power. Further validation studies are warranted to assess the utility of this simple combination model in other independent cohorts.
