This definition includes cases of undiagnosed type 2 diabetes mellitus(T2 DM) identified early in pregnancy and true GDM which develops later. GDM constitutes a greater impact on diabetes epidemic as it carries a major risk of developing T2 DM to the mother and foetus later in life. In addition, GDM has also been linked with cardiometabolic risk factors such as lipid abnormalities, hypertensive disorders and hyperinsulinemia. These might result in later development of cardiovascular disease and metabolic syndrome. The understanding of the different risk factors, the pathophysiological mechanisms and the genetic factors of GDM, will help us to identify the women at risk, to develop effective preventive measures and to provide adequate management of the disease. Clinical trials have shown that T2 DM can be prevented in women with prior GDM, by intensive lifestyle modification and by using pioglitazone and metformin. However, a matter of controversy surrounding both screening and management of GDM continues to emerge, despite several recent welldesigned clinical trials tackling these issues. The aim of this manuscript is to critically review GDM in a detailed and comprehensive manner, in order to provide a scientific analysis and updated write-up of different related aspects.展开更多

Among them, 31 proteins were found to be upregulated notably and the rest16 proteins were downregulated remarkably. Bioinformatic data report revealed abnormal expression of proteinsassociated with lipid metabolism, coagulation cascade activation, complement system and inflammatory responsein the GDM group. ELISA results showed that the contents of RBP4, as well as ANGPTL8, increased in the serumof GDM gravidas compared with the healthy ones, and this change was found to initiate from 12 wk to 16 wk ofgestation.CONCLUSION GDM symptoms may involve abnormalities in lipid metabolism, coagulation cascade activation, complementsystem and inflammatory response. RBP4 and ANGPTL8 are expected to be early predictors of GDM.展开更多

The oral glucose tolerance test is the gold standard for diagnosing gestational diabetes mellitus. Nevertheless, the oral glucose tolerance test is time-consuming and requires patient preparation. On the contrary, Glycated albumin does not require patient preparation or administration of any substance. Most studies on glycated albumin in pregnancy were among the non-African population, and black Americans have higher glycated albumin levels than Caucasians. This study determined the use of glycated albumin in diagnosing gestational diabetes mellitus among pregnant women. The study was a prospective study of 160 pregnant women between 24 and 28 weeks of gestation at the University of Port Harcourt Teaching Hospital. The diagnosis of gestational diabetes mellitus was based on the World Health Organization 2013 criteria. The diagnostic value of glycated albumin was determined using the area under the receiver operator characteristic curve. The prevalence of gestational diabetes mellitus was 9.4% and the mean glycated albumin was 16.91% (±2.77). The area under the receiver operator characteristic curve for glycated albumin was 0.845 (95% CI 0.733 - 0.956;p = 0.0001). The optimal cut-off value of glycated albumin in the diagnosis of gestational diabetes mellitus was 18.9%. Glycated albumin was useful in the diagnosis of gestational diabetes mellitus at 24 to 28 weeks of gestation.展开更多

The frequent absence of clear protocols and guidelines for the correct diagnosis of the pathology results in inadequate classification, imprecise treatment and failed post-therapeutic observation, increasing the risk of relapses, morbidity and mortality. The present study aims to point out updated national and international practice protocols of diagnosis of GTD, through an integrative review. Seven articles were selected and it was observed that the main international reference centers are agreed with the management suggested by the IFGO (International Federation of Gynecology and Obstetrics), being the conduct in the Hydatidiform Mole (HM): evacuation by suction and curettage under ultrasound guidance, followed by hCG monitoring every 1 - 2 weeks until normalized (usually one month for Partial Hydatidiform Mole six months for Complete Hydatidiform Mole and one year for Gestational Trophoblastic Neoplasia). Unfortunately, regarding the diagnosis of MH, the guidelines of some countries show the absence or difficulty of access to the karyotype test and ploid p57 or pelvic ultrasound accompanying the uterine curettage, contrary to what is proposed by the IFGO guideline. Establishing and complying with consistent guidelines can improve patient care, with early diagnosis of the pathology and its complications, reducing the rate of recurrence, morbidity and mortality, especially in less developed countries.展开更多

Currently, the diagnostic criteria for gestational diabetes mellitus are IADPSG criteria (International Association of Diabetes and Pregnancy Study Group), and 75 g oral glucose tolerance test is recommended at 24 - 28 weeks of gestation. Gestational diabetes is associated with many pregnancy complications, such as macrosomia, preterm delivery and increased cesarean section rates, and neonatal complications such as hypoglycemia, hypoxia, and respiratory distress syndrome. Early identification of high-risk groups can be carried out for early prevention and intervention which are conducive to improving mothers and infants perinatal outcome. For the treatment of gestational diabetes, lifestyle interventions, such as improved diet combined with exercise to control blood sugar, are recommended first. For patients with poor blood glucose control, insulin is recommended for blood glucose control, and oral drug use is still controversial.展开更多

Unfortunately, both clinicians and patients are often reluctant to begin insulin therapy, a phenomenon that has been known as psychological insulin resistance (PIR). Objectives: To assess the barriers of initiating insulin among GDM pregnant women. Patients and Methods: An observational cross-sectional study was conducted in the GDM clinic, Diabetes Center in Hera’a General Hospital, Makkah, Saudi Arabia in a period of 4 months. A self-administered validated questionnaire was adopted. It included socio-demographic data of women, perceived (personal, social, pharmacological, occupational and misconception) barriers towards insulin therapy and possible solutions to overcome these barriers. Results: A total of 164 pregnant women with gestational diabetes were included in the study. The age of 36.4% of them exceeded 35 years. Among personal barriers, preferring other treatment methods over insulin (56.4%) and unaware of insulin dose control method (45.4%) were commonly reported. Regarding family barriers, 23.6% reported past family experience of insulin-related complications. Concerning side effects, fear of hypoglycemia (59.4%) and fear of weight gain (50.9%) were most frequently reported barriers against use of insulin. Regarding misconceptions about insulin injections, 26% believed that insulin is addictive;the injection will continue for life. Among work-related barriers, irregular eating times during working hours and long working hours (55.2%) were barriers for insulin use. Facilitating access to healthcare services (94%), engage the patient in decision-making and development of the treatment plan (91.6%), activate virtual clinics and social media for remote follow-up (86.6%) and organize social support groups for pregnant women who use insulin to share their experiences were the most frequently reported possible solutions to initiate and commit to insulin therapy. Conclusion: Various barriers were identified against initiation of insulin therapy in the management of gestational diabetes;mostly due to personal factors, misconception and work-related factors.

文摘Gestational diabetes mellitus(GDM) is defined as any degree of hyperglycaemia that is recognized for the first time during pregnancy. This definition includes cases of undiagnosed type 2 diabetes mellitus(T2 DM) identified early in pregnancy and true GDM which develops later. GDM constitutes a greater impact on diabetes epidemic as it carries a major risk of developing T2 DM to the mother and foetus later in life. In addition, GDM has also been linked with cardiometabolic risk factors such as lipid abnormalities, hypertensive disorders and hyperinsulinemia. These might result in later development of cardiovascular disease and metabolic syndrome. The understanding of the different risk factors, the pathophysiological mechanisms and the genetic factors of GDM, will help us to identify the women at risk, to develop effective preventive measures and to provide adequate management of the disease. Clinical trials have shown that T2 DM can be prevented in women with prior GDM, by intensive lifestyle modification and by using pioglitazone and metformin. However, a matter of controversy surrounding both screening and management of GDM continues to emerge, despite several recent welldesigned clinical trials tackling these issues. The aim of this manuscript is to critically review GDM in a detailed and comprehensive manner, in order to provide a scientific analysis and updated write-up of different related aspects.

文摘BACKGROUND Prolonged fetal exposure to hyperglycemia may increase the risk of developing abnormal glucose metabolism and type-2 diabetes during childhood,adolescence,and adulthood;however,the mechanisms by which gestational diabetes mellitus(GDM)predisposes offspring to metabolic disorders remain unknown.AIM To quantify the nerve axons,macrophages,and vasculature in the pancreas from adult offspring born from mouse dams with GDM.METHODS GDM was induced by i.p.administration of streptozotocin(STZ)in ICR mouse dams.At 12 wk old,fasting blood glucose levels were determined in offspring.At 15 wk old,female offspring born from dams with and without GDM were sacrificed and pancreata were processed for immunohistochemistry.We quantified the density of sensory[calcitonin gene-related peptide(CGRP)]and tyrosine hydroxylase(TH)axons,blood vessels(endomucin),and macro-phages(CD68)in the splenic pancreas using confocal microscopy.RESULTS Offspring mice born from STZ-treated dams had similar body weight and blood glucose values compared to offspring born from vehicle-treated dams.However,the density of CGRP+and TH+axons,endomucin+blood vessels,and CD68+macrophages in the exocrine pancreas was significantly greater in offspring from mothers with GDM vs control offspring.Likewise,the microvasculature in the islets was significantly greater,but not the number of macrophages within the islets of offspring born from dams with GDM compared to control mice.CONCLUSION GDM induces neuronal,vascular,and inflammatory changes in the pancreas of adult progeny,which may partially explain the higher propensity for offspring of mothers with GDM to develop metabolic diseases.

文摘BACKGROUND Fulminant type 1 diabetes mellitus(FT1DM)that occurs during pregnancy or the perinatal period is known as pregnancy-related FT1DM(PF),always without history of abnormal glucose metabolism.Here,we present four patients who developed FT1DM during treatment but were first diagnosed with gestational diabetes mellitus(GDM).CASE SUMMARY The clinical data of four patients with GDM combined with FT1DM admitted to our hospital between July 2018 and April 2021 were collected,and the patients and their infants were followed up.All patients were diagnosed with GDM during the second trimester and were treated.The blood glucose level elevated suddenly during the third trimester and then were diagnosed with FT1DM.Two patients had an insulin allergy,and two had symptoms of upper respiratory tract infection before onset.One patient developed ketoacidosis,and three developed ketosis.Two patients had cesarean section deliveries,and two had vaginal deliveries.The growth and development of the infants were normal.C-peptide levels were lower than those at onset,suggesting progressive impairment of islet function.The frequencies of the DRB109:01,DQB103:03,DQA103:02,DPA101:03,DPA102:02,DPB105:01,DRB401:03,G 01:01,and G 01:04 human leukocyte antigen(HLA)-G alleles were high in the present study.CONCLUSION In comparison with pregnancy-associated FT1DM(PF),patients with GDM combined with FT1DM had an older age of onset,higher body mass index,slower onset,fewer prodromal symptoms,and less acidosis.The pathogenesis may be due to various factors affecting the already fragileβ-cells of GDM patients with genetically susceptible class II HLA genotypes.We speculate that GDM combined with FT1DM during pregnancy,referred to as“double diabetes,”is a subtype of PF with its own unique characteristics that should be investigated further.
文摘Gestational diabetes mellitus(GDM)is a pregnancy-related complication characterized by abnormal glucose metabolism in pregnant women and has an important impact on fetal development.As a bridge between the mother and the fetus,the placenta has nutrient transport functions,endocrine functions,etc.,and can regulate placental nutrient transport and fetal growth and development according to maternal metabolic status.Only by means of placental transmission can changes in maternal hyperglycemia affect the fetus.There are many reports on the placental pathophysiological changes associated with GDM,the impacts of GDM on the growth and development of offspring,and the prevalence of GDM in offspring after birth.Placental epigenetic changes in GDM are involved in the programming of fetal development and are involved in the pathogenesis of later chronic diseases.This paper summarizes the effects of changes in placental nutrient transport function and hormone secretion levels due to maternal hyperglycemia and hyperinsulinemia on the development of offspring as well as the participation of changes in placental epigenetic modifications due to maternal hyperglycemia in intrauterine fetal programming to promote a comprehensive understanding of the impacts of placental epigenetic modifications on the development of offspring from patients with GDM.

文摘BACKGROUND As a well-known fact to the public,gestational diabetes mellitus(GDM)could bring serious risks for both pregnant women and infants.During this important investigation into the linkage between GDM patients and their altered expression in the serum,proteomics techniques were deployed to detect the differentially expressed proteins(DEPs)of in the serum of GDM patients to further explore its pathogenesis,and find out possible biomarkers to forecast GDM occurrence.METHODS Subjects were divided into GDM and normal control groups according to the IADPSG diagnostic criteria.Serum samples were randomly selected from four cases in each group at 24-28 wk of gestation,and the blood samples were identified by applying iTRAQ technology combined with liquid chromatography-tandem mass spectrometry.Key proteins and signaling pathways associated with GDM were identified by bioinformatics analysis,and the expression of key proteins in serum from 12 wk to 16 wk of gestation was further verified using enzyme-linked immunosorbent assay (ELISA).RESULTS Forty-seven proteins were significantly differentially expressed by analyzing the serum samples between the GDMgravidas as well as the healthy ones. Among them, 31 proteins were found to be upregulated notably and the rest16 proteins were downregulated remarkably. Bioinformatic data report revealed abnormal expression of proteinsassociated with lipid metabolism, coagulation cascade activation, complement system and inflammatory responsein the GDM group. ELISA results showed that the contents of RBP4, as well as ANGPTL8, increased in the serumof GDM gravidas compared with the healthy ones, and this change was found to initiate from 12 wk to 16 wk ofgestation.CONCLUSION GDM symptoms may involve abnormalities in lipid metabolism, coagulation cascade activation, complementsystem and inflammatory response. RBP4 and ANGPTL8 are expected to be early predictors of GDM.
文摘BACKGROUND This case of gestational gingival tumor is huge and extremely rare in clinical practice.As the growth location of this gingival tumor is in the upper anterior tooth area,it seriously affects the pregnant woman's speech and food,causing great pain to the patient.The use of Nd:YGA water mist laser to remove the gingival tumor resulted in minimal intraoperative bleeding,minimal adverse reactions,and good postoperative healing,which is worthy of clinical promotion and application.CASE SUMMARY The patient,a pregnant woman,reported a large lump in her mouth on the first day of postpartum treatment.Based on medical history and clinical examination,the diagnosis was diagnosed as gestational gingival tumor.Postoperative pathological biopsy also confirmed this diagnosis.The use of Nd:YAG water mist laser to remove the tumor resulted in minimal intraoperative bleeding,clear surgical field of view,short surgical time,and good postoperative healing.CONCLUSION In comparison to traditional surgery,Nd:YAG water mist laser surgery is minimally invasive,minimizes cell damage,reduces bleeding,ensures a clear field of vision,and virtually eliminates postoperative edema,carbonization,and the risk of cross infection.It has unique advantages in oral soft tissue surgery for pregnant patients.Therefore,the clinical application of Nd:YAG water mist laser for the treatment of gestational gingival tumors is an ideal choice.
文摘Gestational diabetes is typically diagnosed in the late second or third trimester of pregnancy.It is one of the most common metabolic disorders among expectant mothers,with potential serious short-and long-term complications for both maternal and offspring health.C-peptide is secreted from pancreatic beta-cells into circulation in equimolar amounts with insulin.It is a useful biomarker to estimate the beta-cell function because it undergoes negligible hepatic clearance and consequently it has a longer half-life compared to insulin.Pregnancy induces increased insulin resistance due to physiological changes in hormonal and metabolic homeostasis.Inadequate compensation by islet beta-cells results in hyperglycemia.The standard oral glucose tolerance test at 24-28 wk of gestation sets the diagnosis.Accumulated evidence from prospective studies indicates a link between early pregnancy C-peptide levels and the risk of subsequent gestational diabetes.Elevated C-peptide levels and surrogate glycemic indices at the beginning of pregnancy could prompt appropriate strategies for secondary prevention.
文摘Gestational diabetes mellitus is the most common endocrine disorder in pregnancy and a cause of maternal and fetal morbidities and mortalities. The oral glucose tolerance test is the gold standard for diagnosing gestational diabetes mellitus. Nevertheless, the oral glucose tolerance test is time-consuming and requires patient preparation. On the contrary, Glycated albumin does not require patient preparation or administration of any substance. Most studies on glycated albumin in pregnancy were among the non-African population, and black Americans have higher glycated albumin levels than Caucasians. This study determined the use of glycated albumin in diagnosing gestational diabetes mellitus among pregnant women. The study was a prospective study of 160 pregnant women between 24 and 28 weeks of gestation at the University of Port Harcourt Teaching Hospital. The diagnosis of gestational diabetes mellitus was based on the World Health Organization 2013 criteria. The diagnostic value of glycated albumin was determined using the area under the receiver operator characteristic curve. The prevalence of gestational diabetes mellitus was 9.4% and the mean glycated albumin was 16.91% (±2.77). The area under the receiver operator characteristic curve for glycated albumin was 0.845 (95% CI 0.733 - 0.956;p = 0.0001). The optimal cut-off value of glycated albumin in the diagnosis of gestational diabetes mellitus was 18.9%. Glycated albumin was useful in the diagnosis of gestational diabetes mellitus at 24 to 28 weeks of gestation.
文摘BACKGROUND The evidence from observational studies has been inconclusive on the causal relationship between cheese intake and gestational hypertension or diabetes.AIM To determine whether cheese consumption was causally related to hypertension and diabetes during pregnancy.METHODS This was a two-sample Mendelian randomized(MR)study.Summary-level genetic data for cheese intake was exposure and corresponding outcome data for gestational hypertension and gestational diabetes were extracted from the IEU OpenGWAS database.MR analysis was conducted using inverse variance weighting.For sensitivity analyses,MR-Egger regression,weighted median,weighted mode,and leave-one-out methods were conducted.A fixed-effect model was used to meta-analyze two sample MR estimates.The traits of gestational hypertension were pregnancy hypertension(123579 individuals)and oedema,proteinuria and hypertensive disorders in pregnancy,childbirth and the puerperium(123579 individuals),and traits of gestational diabetes were gestational diabetes(123579 individuals)and diabetes mellitus in pregnancy(116363 individuals),respectively.RESULTS Cheese intake per standard deviation increase has causally reduced the risks of gestational hypertension[odds ratio(OR)=0.60,95%confidence interval(CI):0.47-0.76,P<0.001]and gestational diabetes(OR=0.41,95%CI:0.30-0.55,P<0.001)in inverse variance weighted analysis.Sensitivity analysis showed no heterogeneity(all P>0.05)nor horizontal pleiotropy(all P>0.05)in the relationship between cheese intake and gestational hypertension,but heterogeneity presented(all P<0.05)in relation to gestational diabetes in the two-sample MR analysis.CONCLUSION Cheese intake was inversely associated with gestational hypertension and gestational diabetes in MR analysis,suggesting that cheese consumption may be beneficial in preventing hypertension and diabetes during pregnancy.

文摘The placenta plays an important role in nutrient transport to maintain the growth and development of the embryo.Gestational diabetes mellitus(GDM),the most common complication during pregnancy,highly affects placental function in late gestation.Advanced glycation end-products(AGEs),a complex and heterogeneous group of compounds engaged by the receptor for AGEs(RAGE),are closely associated with diabetes-related complications.In this study,AGEs induced a decrease in the expression of tight junction(TJ)proteins in BeWo cells and increased the paracellular permeability of trophoblast cells by regulating RAGE/NF-κB.Sprague-Dawley(SD)rats injected with 100 mg/kg AGEs-rat serum albumin(RSA)via the tail vein from embryo day 2 were set as the placental barrier dysfunction model group(n=10).The effect of AGEs on placental permeability was determined using the Evans-Blue dye extravasation method.The ultrastructure of the placenta samples was observed by transmission electron microscopy.The effects of AGEs on the placenta were confirmed by treating rats with RAGE antagonist FPS-ZM1 and soluble forms of RAGE(sRAGE).AGEs treatment increased placental permeability and disrupted the tight junctions in pregnant rat placenta,but has no effect on blood glucose.The expression of TJ-related proteins,including ZO-1,Occludin,and Claudin 5,were downregulated after AGEs treatment.Further,AGEs treatment increased the expression of RAGE and nuclear factor-κB in the placenta of rats and upregulated the levels of vascular endothelial growth factor.The effects of AGEs on the placenta were blocked by RAGE antagonist FPS-ZM1 and sRAGE.This study demonstrates the mechanism underlying AGEs-induced disturbance in placental function in pregnant rats and highlights the potential of AGEs in the treatment of GDM.
文摘BACKGROUND Gestational diabetes mellitus(GDM)refers to hyperglycemia caused by insulin resistance or insufficient insulin secretion during pregnancy.Patients with GDM have a high risk of pregnancy complications,which can adversely affect both maternal and fetal health.Therefore,early diagnosis,treatment and monitoring of GDM are essential.In recent years,a new treatment scheme represented by insulin aspart combined with metformin has received increasing attention.AIM To explore the effects of insulin aspart combined with metformin on patients with GDM and inflammatory markers.METHODS From April 2020 to September 2022,124 patients with GDM in Sanya Women and Children’s Hospital Managed by Shanghai Children’s Medical Center were collected and analyzed retrospectively.The control group(CG)comprised 62 patients treated with insulin aspart alone,and 62 patients treated with insulin aspart and metformin formed the observation group(OG).Before and after treatment,improvement of blood-glucose-related indexes[fasting blood glucose(FBG),2-h postprandial glucose(2h PG)and hemoglobin A1c(HbA1c)],serum related factor[serum homocysteine(Hcy)],serum inflammatory cytokines[tumor necrosis factor(TNF)-α,interleukin(IL)-6 and C-reactive protein(CRP)]were compared between the two groups.The clinical efficacy,adverse pregnancy outcomes and incidence of pregnancy complications were compared between the two groups.RESULTS After treatment,the levels of FBG,2h PG,HbA1c,Hcy,TNF-α,IL-6 and CRP in both groups were significantly decreased(P<0.05),and the levels of FBG,2h PG,HbA1c,Hcy,TNF-α,IL-6 and CRP in the OG were lower than in the CG(P<0.05).The total clinical effectiveness in the OG was higher than that in the CG(P<0.05).The total incidence of adverse pregnancy outcomes and complications in the OG was significantly lower than in the CG(P<0.05).CONCLUSION Insulin aspart combined with metformin are effective for treatment of GDM,which can reduce blood-glucoserelated indexes,Hcy and serum inflammatory cytokines,and risk of adverse pregnancy outcomes and complications.
文摘During the global coronavirus disease 2019(COVID-19)pandemic,people worldwide have experienced an unprecedented rise in psychological distress and anxiety.In addition to this challenging situation,the prevalence of diabetes mellitus(DM),a hidden epidemic,has been steadily increasing in recent years.Lower-middle-income countries have faced significant barriers in providing accessible prenatal care and promoting a healthy diet for pregnant women,and the pandemic has made these challenges even more difficult to overcome.Pregnant women are at a higher risk of developing complications such as hypertension,preeclampsia,and gestational diabetes,all of which can have adverse implications for both maternal and fetal health.The occurrence of gestational diabetes has been on the rise,and it is possible that the pandemic has worsened its prevalence.Although data is limited,studies conducted in Italy and Canada suggest that the pandemic has had an impact on gestational diabetes rates,especially among women in their first trimester of pregnancy.The significant disruptions to daily routines caused by the pandemic,such as limited exercise options,indicate a possible link between COVID-19 and an increased likelihood of experiencing higher levels of weight gain during pregnancy.Notably,individuals in the United States with singleton pregnancies are at a significantly higher risk of excessive gestational weight gain,making this association particularly important to consider.Although comprehensive data is currently lacking,it is important for clinical researchers to explore the possibility of establishing correlations between the stress experienced during the pandemic,its consequences such as gestational gain weight,and the increasing incidence of gestational DM.This knowledge would contribute to better preventive measures and support for pregnant individuals during challenging times.

文摘The incidence rate of diabetes in pregnancy is about 20%,and diabetes in pregnancy will have a long-term impact on the metabolic health of mothers and their offspring.Mothers may have elevated blood glucose,which may lead to blood pressure disease,kidney disease,decreased resistance and secondary infection during pregnancy.The offspring may suffer from abnormal embryonic development,intrauterine growth restriction,obesity,autism,and other adverse consequences.Resveratrol(RSV)is a natural polyphenol compound,which is found in more than 70 plant species and their products,such as Polygonum cuspidatum,seeds of grapes,peanuts,blueberries,bilberries,and cranberries.Previous studies have shown that RSV has a potential beneficial effect on complex pregnancy,including improving the indicators of diabetes and pregnancy diabetes syndrome.This article has reviewed the molecular targets and signaling pathways of RSV,including AMP-activated protein kinase,mitogen-activated protein kinases,silent information regulator sirtuin 1,miR-23a-3p,reactive oxygen species,potassium channels and CX3C chemokine ligand 1,and the effect of RSV on gestational diabetes mellitus(GDM)and its complications.RSV improves the indicators of GDM by improving glucose metabolism and insulin tolerance,regulating blood lipids and plasma adipokines,and modulating embryonic oxidative stress and apoptosis.Furthermore,RSV can ameliorate the GDM complications by reducing oxidative stress,reducing the effects on placentation,reducing the adverse effects on embryonic development,reducing offspring's healthy risk,and so on.Thus,this review is of great significance for providing more options and possibilities for further research on medication of gestational diabetes.
文摘BACKGROUND Gestational diabetes mellitus(GDM)is a condition characterized by high blood sugar levels during pregnancy.The prevalence of GDM is on the rise globally,and this trend is particularly evident in China,which has emerged as a significant issue impacting the well-being of expectant mothers and their fetuses.Identifying and addressing GDM in a timely manner is crucial for maintaining the health of both expectant mothers and their developing fetuses.Therefore,this study aims to establish a risk prediction model for GDM and explore the effects of serum ferritin,blood glucose,and body mass index(BMI)on the occurrence of GDM.AIM To develop a risk prediction model to analyze factors leading to GDM,and evaluate its efficiency for early prevention.METHODS The clinical data of 406 pregnant women who underwent routine prenatal examination in Fujian Maternity and Child Health Hospital from April 2020 to December 2022 were retrospectively analyzed.According to whether GDM occurred,they were divided into two groups to analyze the related factors affecting GDM.Then,according to the weight of the relevant risk factors,the training set and the verification set were divided at a ratio of 7:3.Subsequently,a risk prediction model was established using logistic regression and random forest models,and the model was evaluated and verified.RESULTS Pre-pregnancy BMI,previous history of GDM or macrosomia,hypertension,hemoglobin(Hb)level,triglyceride level,family history of diabetes,serum ferritin,and fasting blood glucose levels during early pregnancy were determined.These factors were found to have a significant impact on the development of GDM(P<0.05).According to the nomogram model’s prediction of GDM in pregnancy,the area under the curve(AUC)was determined to be 0.883[95%confidence interval(CI):0.846-0.921],and the sensitivity and specificity were 74.1%and 87.6%,respectively.The top five variables in the random forest model for predicting the occurrence of GDM were serum ferritin,fasting blood glucose in early pregnancy,pre-pregnancy BMI,Hb level and triglyceride level.The random forest model achieved an AUC of 0.950(95%CI:0.927-0.973),the sensitivity was 84.8%,and the specificity was 91.4%.The Delong test showed that the AUC value of the random forest model was higher than that of the decision tree model(P<0.05).CONCLUSION The random forest model is superior to the nomogram model in predicting the risk of GDM.This method is helpful for early diagnosis and appropriate intervention of GDM.
文摘BACKGROUND In contrast to overt diabetes mellitus(DM),gestational DM(GDM)is defined as impaired glucose tolerance induced by pregnancy,which may arise from exaggerated physiologic changes in glucose metabolism.GDM prevalence is reported to be as high as 20%among pregnancies depending on the screening method,gestational age,and the population studied.Maternal and fetal effects of uncontrolled GDM include stillbirth,macrosomia,neonatal diabetes,birth trauma,and subsequent postpartum hemorrhage.Therefore,it is essential to find the potential target population and associated predictive and preventive measures for future intensive peripartum care.AIM To review studies that explored the cellular and molecular mechanisms of GDM as well as predictive measures and prevention strategies.METHODS The search was performed in the Medline and PubMed databases using the terms“gestational diabetes mellitus,”“overt diabetes mellitus,”and“insulin resistance.”In the literature,only full-text articles were considered for inclusion(237 articles).Furthermore,articles published before 1997 and duplicate articles were excluded.After a final review by two experts,all studies(1997-2023)included in the review met the search terms and search strategy(identification from the database,screening of the studies,selection of potential articles,and final inclusion).RESULTS Finally,a total of 79 articles were collected for review.Reported risk factors for GDM included maternal obesity or overweight,pre-existing DM,and polycystic ovary syndrome.The pathophysiology of GDM involves genetic variants responsible for insulin secretion and glycemic control,pancreaticβcell depletion or dysfunction,aggravated insulin resistance due to failure in the plasma membrane translocation of glucose transporter 4,and the effects of chronic,low-grade inflammation.Currently,many antepartum measurements including adipokines(leptin),body mass ratio(waist circumference and waist-to-hip ratio),and biomarkers(microRNA in extracellular vesicles)have been studied and confirmed to be useful markers for predicting GDM.For preventing GDM,physical activity and dietary approaches are effective interventions to control body weight,improve glycemic control,and reduce insulin resistance.CONCLUSION This review explored the possible factors that influence GDM and the underlying molecular and cellular mechanisms of GDM and provided predictive measures and prevention strategies based on results of clinical studies.
文摘BACKGROUND Gestational diabetes mellitus(GDM)has become increasingly prevalent globally.Glycemic control in pregnant women with GDM has a critical role in neonatal complications.AIM To analyze the early neonatal complications in GDM,and examine the effect of blood glucose control level on neonatal infection.METHODS The clinical data of 236 pregnant women with GDM and 240 healthy pregnant women and newborns during from March 2020 to December 2021 the same period were retrospectively analyzed,and the early complications in newborns in the two groups were compared.The patients were divided into the conforming glycemic control group(CGC group)and the non-conforming glycemic control group(NCGC group)based on whether glycemic control in the pregnant women with GDM conformed to standards.Baseline data,immune function,infectionrelated markers,and infection rates in neonates were compared between the two groups.RESULTS The incidence of neonatal complications in the 236 neonates in the GDM group was significantly higher than that in the control group(P<0.05).Pregnant women with GDM in the NCGC group(n=178)had significantly higher fasting plasma glucose,2 h postprandial blood glucose and glycated hemoglobin A1C levels than those in the CGC group(n=58)(P<0.05).There were no differences in baseline data between the two groups(P>0.05).Additionally,the NCGC group had significantly decreased peripheral blood CD3^(+),CD4^(+),CD8^(+)T cell ratios,CD4/CD8 ratios and immunoglobulin G in neonates compared with the CGC group(P<0.05),while white blood cells,serum procalcitonin and C-reactive protein levels increased significantly.The neonatal infection rate was also significantly increased in the NCGC group(P<0.05).CONCLUSION The risk of neonatal complications increased in pregnant women with GDM.Poor glycemic control decreased neonatal immune function,and increased the incidence of neonatal infections.
文摘GTD (Gestational Trophoblastic Disease) is a pathology that encompasses benign and malignant clinical forms, affects women of childbearing age, has a variable incidence and is more frequent in developing or underdeveloped countries, colliding with the economic barrier. The frequent absence of clear protocols and guidelines for the correct diagnosis of the pathology results in inadequate classification, imprecise treatment and failed post-therapeutic observation, increasing the risk of relapses, morbidity and mortality. The present study aims to point out updated national and international practice protocols of diagnosis of GTD, through an integrative review. Seven articles were selected and it was observed that the main international reference centers are agreed with the management suggested by the IFGO (International Federation of Gynecology and Obstetrics), being the conduct in the Hydatidiform Mole (HM): evacuation by suction and curettage under ultrasound guidance, followed by hCG monitoring every 1 - 2 weeks until normalized (usually one month for Partial Hydatidiform Mole six months for Complete Hydatidiform Mole and one year for Gestational Trophoblastic Neoplasia). Unfortunately, regarding the diagnosis of MH, the guidelines of some countries show the absence or difficulty of access to the karyotype test and ploid p57 or pelvic ultrasound accompanying the uterine curettage, contrary to what is proposed by the IFGO guideline. Establishing and complying with consistent guidelines can improve patient care, with early diagnosis of the pathology and its complications, reducing the rate of recurrence, morbidity and mortality, especially in less developed countries.
文摘Pre-pregnancy glucose metabolism is normal, only during pregnancy diabetes known as gestational diabetes mellitus. Currently, the diagnostic criteria for gestational diabetes mellitus are IADPSG criteria (International Association of Diabetes and Pregnancy Study Group), and 75 g oral glucose tolerance test is recommended at 24 - 28 weeks of gestation. Gestational diabetes is associated with many pregnancy complications, such as macrosomia, preterm delivery and increased cesarean section rates, and neonatal complications such as hypoglycemia, hypoxia, and respiratory distress syndrome. Early identification of high-risk groups can be carried out for early prevention and intervention which are conducive to improving mothers and infants perinatal outcome. For the treatment of gestational diabetes, lifestyle interventions, such as improved diet combined with exercise to control blood sugar, are recommended first. For patients with poor blood glucose control, insulin is recommended for blood glucose control, and oral drug use is still controversial.
文摘Background: Gestational diabetes mellitus (GDM) is one of the most common pathologies in pregnancy. Unfortunately, both clinicians and patients are often reluctant to begin insulin therapy, a phenomenon that has been known as psychological insulin resistance (PIR). Objectives: To assess the barriers of initiating insulin among GDM pregnant women. Patients and Methods: An observational cross-sectional study was conducted in the GDM clinic, Diabetes Center in Hera’a General Hospital, Makkah, Saudi Arabia in a period of 4 months. A self-administered validated questionnaire was adopted. It included socio-demographic data of women, perceived (personal, social, pharmacological, occupational and misconception) barriers towards insulin therapy and possible solutions to overcome these barriers. Results: A total of 164 pregnant women with gestational diabetes were included in the study. The age of 36.4% of them exceeded 35 years. Among personal barriers, preferring other treatment methods over insulin (56.4%) and unaware of insulin dose control method (45.4%) were commonly reported. Regarding family barriers, 23.6% reported past family experience of insulin-related complications. Concerning side effects, fear of hypoglycemia (59.4%) and fear of weight gain (50.9%) were most frequently reported barriers against use of insulin. Regarding misconceptions about insulin injections, 26% believed that insulin is addictive;the injection will continue for life. Among work-related barriers, irregular eating times during working hours and long working hours (55.2%) were barriers for insulin use. Facilitating access to healthcare services (94%), engage the patient in decision-making and development of the treatment plan (91.6%), activate virtual clinics and social media for remote follow-up (86.6%) and organize social support groups for pregnant women who use insulin to share their experiences were the most frequently reported possible solutions to initiate and commit to insulin therapy. Conclusion: Various barriers were identified against initiation of insulin therapy in the management of gestational diabetes;mostly due to personal factors, misconception and work-related factors. Prompt actions are needed to overcome these barriers.
