ABSTRACT
RESUMEN Objetivo: Identificar la influencia del consumo de hidratos de carbono (HCO) sobre el estado oxidante en mujeres con y sin diabetes mellitus gestacional (DMG). Materiales y métodos: Se realizó un estudio transversal, observacional y comparativo a dos grupos de 21 mujeres con y sin DMG, respectivamente, en la ciudad de Toluca, México, de enero a diciembre del 2022. Para evaluar parámetros sociodemográficos, se les aplicó un cuestionario de historia clínica; en cuanto a los parámetros antropométricos, se les midió peso corporal y estatura; y respecto a los parámetros bioquímicos, colesterol total (CT) y triglicéridos (TG). Para evaluar el estado oxidante/antioxidante se cuantificaron, como marcador oxidante, el malondihaldeído (MDA), y como antioxidantes, catalasa (cat), superóxido dismutasa (SOD) y capacidad antioxidante total (CAT). Los hábitos dietéticos se evaluaron a través de un recordatorio de 24 horas, en ambos grupos de mujeres, para obtener los macronutrientes: proteínas, lípidos e HCO. A partir de los hidratos de carbono totales (HCOT), se calcularon los hidratos de carbono complejos (HCOC) e hidratos de carbono simples (HCOS) como la sacarosa. Para el cálculo de HCOS por día, se usó la lista de alimentos con contenido de sacarosa por cada 100 gramos de consumo que emplea el Sistema Mexicano de Equivalentes; para el análisis de dieta, se utilizó el programa Nutrikcal VO. Se usaron las pruebas estadísticas t de Student para muestras independientes, U de Mann-Whitney para las variables no homogéneas y se realizó la correlación de Spearman (p < 0,05) en el programa SPSS, versión 19. Resultados: Los resultados mostraron que la diferencia entre los valores de CT (p < 0,029), TG (p < 0,029), las enzimas: cat (p < 0,011), SOD (p < 0,013), así como el MDA (p < 0,039), fueron significativamente mayores en las pacientes del grupo con DMG en comparación con el grupo sin DMG. Además, el grupo con DMG consumió mayor proporción de sacarosa. Conclusiones: Las mujeres con DMG tienen un desequilibrio en el estado oxidante/antioxidante influenciado por el tipo de HCO que consumen, en particular los HCOS como la sacarosa.
ABSTRACT Objective: To identify the influence of carbohydrate (CHO) intake on oxidative status among women with and without gestational diabetes mellitus (GDM). Materials and methods: A cross-sectional, observational and comparative study was carried out with two groups of 21 women each with and without GDM in the city of Toluca, Mexico, from January to December 2022. The sociodemographic parameters were determined by administering the patients a medical history questionnaire; anthropometric parameters such as body weight and height were measured; and biochemical parameters including total cholesterol (TC) and triglycerides (TG) were calculated. The oxidant/antioxidant status was assessed as follows: malondialdehyde (MDA) as oxidative stress marker; and catalase (CAT), superoxide dismutase (SOD) and total antioxidant capacity (TAC) as antioxidants. Dietary habits were evaluated through a 24-hour reminder in both groups of women to obtain the macronutrient classes, i.e., proteins, fats and CHOs. Based on the total carbohydrates (TCHOs), complex (CCHOs) and simple carbohydrates (SCHOs) such as sucrose were calculated. SCHOs per day were measured using the list of foods with sucrose content per 100 grams according to the Mexican Food Equivalence System (SMAE). The NutriKcal VO program was used for the dietary analysis. Statistical tests such as Student's t test and Mann-Whitney U test were performed for the independent samples and nonhomogeneous variables, respectively, and Spearman's rank correlation coefficient (p < 0.05) was determined using the IBM SPSS Statistics V19. Results: The results showed that the difference between the levels of TC (p < 0.029), TG (p < 0.029), enzymes CAT (p < 0.011) and SOD (p < 0.013), as well as MDA (p < 0.039) was significantly higher among patients in the group with GDM compared to that in the group without GDM. In addition, the group with GDM consumed a higher proportion of sucrose. Conclusions: Women with GDM have an imbalance in the oxidant/antioxidant status, influenced by the type of CHO they consume, particularly SCHOs such as sucrose.
ABSTRACT
Objective:To investigate electrocardiogram (ECG) characteristics and related factors of gestational diabetes mellitus (GDM) complicated by depressive disorder.Methods:The clinical data of 243 patients with GDM who received treatment at Peking University Third Hospital from September 2021 to December 2022 were retrospectively analyzed. According to the scoring results of the Self-rating Depression Scale (SDS), these patients were divided into an observation group (GDM + depressive disorder, n = 51) and a control group (GDM alone, n = 192). The χ2 test was used to analyze the relationship between GDM complicated by depressive disorder and ECG diagnosis results. Additionally, the t-test was used to compare ECG indicators between the two groups. Results:Compared with the control group, patients in the observation group had a higher incidence of abnormal ECG indicators, including bradycardia ( χ2 = 4.68, P = 0.030), premature contraction ( χ2 = 10.78, P = 0.001), and atrioventricular block ( χ2 = 15.04, P < 0.001). However, there were no significant differences in the incidences of tachycardia, bundle branch block, or ST-T changes between the two groups (all P > 0.05). Compared with the control group, the observation group exhibited significantly increased heart rate [(73.43 ± 8.24) beats/min vs. (67.22 ± 5.08) beats/min], maximum QT interval [(419.09 ± 36.00) ms vs. (351.95 ± 32.07) ms], minimum QT interval [(363.31 ± 30.78) ms vs. (316.52 ± 29.10) ms], and QT dispersion [(55.78 ± 17.87) ms vs. (35.42 ± 13.18) ms, t = -5.13, -12.95, -10.08, -7.60, all P < 0.001]. Conclusion:Among patients with gestational diabetes mellitus, those with depressive disorder have an increased risk of exhibiting abnormal electrocardiogram patterns compared with those without depressive disorder.
ABSTRACT
Objective To observe the morphological changes of levator hiatus in patients with gestational diabetes mellitus(GDM)after spontaneous delivery with ultrasonography.Methods A total of 302 pregnant women in the first trimester(6-8 weeks)were prospectively observed,and the parameters of pelvic floor muscle hiatus were measured with ultrasound during the first trimester,also 12 weeks,6 months and 1 year after delivery at resting-state(resting period),anal contraction state(systole period)and Valsalva maneuver(tension period),respectively.Blood glucose was measured at 28 weeks of gestation,GDM was diagnosed,and the pregnant women enrolled were divided into GDM group and non-GDM group.The ultrasonic parameters and postpartum pelvic floor muscle tension were compared between groups.Spearman correlation analysis was used to evaluate the correlations of pelvic floor muscle tension grade and anal levator hiatus parameters in GDM group.Results Totally 153 pregnant women were enrolled and assigned into GDM group(n=51)and non-GDM group(n=102).Transversal diameter of levator hiatus(LH-TD),anteroposterior diameter of levator hiatus(LH-APD)and levator hiatus area(LHA)in different periods 12 weeks postpartum in both groups were higher than those in early pregnancy(all P＜0.05).Six months and 1 year postpartum,in GDM group,LH-APD and LHA in systole period,also LH-TD,LH-APD and LHA in tension period were higher than those in early pregnancy(all P＜0.05),while in non-GDM group,LH-APD and LHA in tension period were higher than those of early pregnancy(all P＜0.05).One year after delivery,LH-APD and LHA in systolic period,as well as LH-TD and LHA in tension period in GDM group were all higher than those in non-GDM group(all P＜0.05),whereas the proportion of pelvic floor muscle tension of grade Ⅱ-Ⅲ was higher,of grade Ⅳ-Ⅴ was lower in GDM group than those in non-GDM group(P＜0.05).One year after delivery,pelvic floor muscle tone grade in GDM group was negatively correlated with LH-TD,LH-APD and LHA in resting,systole and tension period(all P＜0.05).Conclusion The morphology of levator hiatus changed greatly in GDM patients after spontaneous delivery,and rehabilitation training should be carried out early.
ABSTRACT
Objective:To explore the drug resistance of pathogens in puerperal infection of pregnant women with diabetes mellitus (GDM), and analyze the influence of puerperal infection on the expression of toll like receptor 4 (TLR4) inflammatory pathway in peripheral blood monocytes.Methods:A retrospective selection was conducted on 120 GDM postpartum women who underwent regular prenatal check ups and delivery at the 903th Hospital of the PLA (People′s Liberation Army) Joint Logistic Support Force from January 2020 to October 2022. The postpartum infection status, pathogenic characteristics of the infected pathogens, and drug resistance of the mothers were analyzed; According to the postpartum infection situation, the parturients were divided into an infected group and an uninfected group. Logistic regression analysis was used to analyze the relevant factors affecting postpartum infection, and the TLR4 protein and mRNA expression levels of peripheral blood mononuclear cells in the two groups were compared.Results:Among 120 GDM pregnant women, 21 cases (17.50%) developed post infection, including 8 cases (38.10%) of incision infection, 6 cases (28.57%) of uterine cavity infection, 4 cases (19.05%) of urinary system infection, and 3 cases (14.28%) of blood infection; A total of 43 pathogenic bacteria were detected, including 26 Gram negative bacteria (60.46%), 14 Gram positive bacteria (32.56%), and 3 fungi (6.98%). Among the main Gram negative bacteria, escherichia coli had the highest resistance rate to ceftazidime and tetracycline, and had not developed resistance to meropenem; Pseudomonas aeruginosa had the highest resistance rate to ceftazidime and gentamicin. Among the main Gram positive bacteria, staphylococcus aureus had the highest resistance rate to penicillin G and ceftazidime, and had not developed resistance to vancomycin; Enterococcus faecalis had the highest resistance rate to clindamycin. The results of multivariate logistic regression analysis showed that postpartum hemorrhage, premature rupture of membranes, and poor control of prenatal blood sugar were independent risk factors for postpartum infection in GDM mothers (all P<0.05). The expression rate of TLR4 protein, relative expression level of TLR4 mRNA, and levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-1, and IL-10 in the infected group were significantly higher than those in the non infected group (all P<0.05). Conclusions:The distribution and drug resistance of pathogenic bacteria in postpartum infections of GDM mothers have certain characteristics. Postpartum hemorrhage, premature rupture of membranes, and poor control of prenatal blood sugar are independent risk factors affecting postpartum infections in GDM mothers; The TLR4 inflammatory pathway in peripheral blood mononuclear cells may be involved in the occurrence and development of postpartum infection in GDM mothers.
ABSTRACT
Objective:To investigate the relationship between adiponectin (ADIPOQ) gene polymorphism and postpartum type 2 diabetes mellitus (T2DM) in pregnant women with gestational diabetes mellitus (GDM).Methods:A retrospective study was conducted on 236 GDM postpartum women admitted to the Affiliated Hospital of Jining Medical College from June 2020 to June 2021 as observation subjects. They were divided into a T2DM group and a non T2DM group based on the occurrence of T2DM after delivery. The clinical data of the two groups were compared. The double deoxygenation end termination method was used to detect the single nucleotide polymorphism (SNP) of the ADIPOQ gene, and the four loci rs17366568, rs822395, rs1501299, and rs2241766 were classified. The relationship between ADIPOQ genotype polymorphism and postpartum T2DM was analyzed using a logistic regression model.Results:The G allele carrying the rs2241766 locus in ADIPOQ gene was negatively correlated with the occurrence of T2DM ( OR=0.71, 0.68, P<0.05). Compared with T2DM patients with TT genotype, the GT+ GG genotype at the rs2241766 locus had a lower risk of occurrence for gestational age ≥2 and HbA 1c>85%. Similarly, T2DM patients with pre pregnancy body mass index (BMI)>25 kg/m 2 were more likely to be carriers of the rs2241766 TT genotype ( P=0.026). The (GT+ TT) genotype carrying the T allele at the rs1501299 locus was a protective factor for gestational age and HbA 1c in T2DM patients. Conclusions:The rs2241766 and rs1501299 polymorphisms of the ADIPOQ gene are associated with susceptibility to postpartum T2DM in GDM women. Individuals with rs2241766 and rs1501299 mutant genotypes belong to the high-risk population for T2DM.
ABSTRACT
Objective:To investigate the impact of abnormal patterns of 75 g oral glucose tolerance test (OGTT) in the second trimester on the risk of large for gestational age (LGA) newborn deliveries.Methods:General clinical data and OGTT results of 66 290 pregnant women who received regular prenatal care and delivered in Guangdong Maternal and Child Health Hospital from December 24, 2016 to July 26, 2022 were collected. According to the results of OGTT, the pregnant women were divided into 8 groups: normal blood glucose group (normal fasting blood glucose, 1-hour and 2-hour after oral glucose, 54 518 cases), gestational diabetes mellitus (GDM) 0 group (only abnormal fasting blood glucose, 1 430 cases), GDM 1 group (only abnormal blood glucose at 1-hour after oral glucose, 2 150 cases), GDM 2 group (only abnormal blood glucose at 2-hour after oral glucose, 3 736 cases), GDM 0+1 group (both fasting blood glucose and 1-hour after oral glucose were abnormal, 371 cases), GDM 0+2 group (both fasting blood glucose and 2-hour after oral glucose were abnormal, 280 cases), GDM 1+2 group (abnormal blood glucose at 1-hour and 2-hour after oral glucose, 2 981 cases) and GDM 0+1+2 group (abnormal fasting blood glucose, 1-hour and 2-hour after oral glucose, 824 cases). Multivariate logistic regression was used to analyze the effects of different abnormal OGTT patterns on LGA. In addition, the blood glucose measurements at the three time points of OGTT were combined and used as continuous variables in the receiver operating characteristic (ROC) curve to evaluate the predictive value of each blood glucose measurement mode for LGA and the area under the curve (AUC) was compared.Results:(1) Multivariate logistic regression analysis showed that the risks of LGA were significantly increased in GDM 0 group ( OR=1.76, 95% CI: 1.50-2.08; P<0.001), GDM 0+1 group ( OR=2.29, 95% CI: 1.72-3.04; P<0.001), and GDM 0+1+2 group ( OR=1.98, 95% CI: 1.61-2.43; P<0.001). (2) ROC curve analysis showed that fasting blood glucose, 1-hour after oral glucose, 2-hour after oral glucose, fasting+1-hour after oral glucose, fasting+2-hour after oral glucose, 1-hour+2-hour after oral glucose, and fasting+1-hour+2-hour after oral glucose had certain predictive value for LGA (all P<0.001). The AUC of fasting blood glucose measurement was higher than that of 2-hour blood glucose measurement in predicting LGA, and the difference was statistically significant ( P<0.05). There was no significant difference in the AUC between fasting blood glucose and other blood glucose measurement modes for predicting LGA (all P>0.05). Conclusions:In the abnormal OGTT patterns, pregnant women with abnormal fasting blood glucose, abnormal fasting+1-hour after oral glucose, and abnormal fasting+1-hour+2-hour after oral glucose have an increased risk of LGA. Fasting blood glucose measurement is of great significance for the prediction of LGA, and could be used as an optimal indicator to evaluate the risk of LGA in clinical practice.

Abstract Objective To assess the effect of goal diversified nursing intervention on the perinatal period of patients with gestational diabetes mellitus (GDM). Methods In this prospective study, 96 patients with GDM treated from February 2020 to February 2023 were selected and randomly divided into observation group (n=48) and control group (n=48). The patients in control group were given routine nursing, based on which those in observation group received goal-oriented diversified nursing intervention. The incidence rates of perioperative complications and adverse neonatal outcomes, and blood glucose indicators, the Chinese Version of the Diabetes Management Self-efficacy Scale (C-DMSES) score and the Diabetes Specific Quality of Life Scale (DSQL) score before and after intervention were compared between the two groups. Results The levels of fasting plasma glucose, 2-hour postprandial blood glucose and glycosylated hemoglobin in the observation group during delivery were lower than those in the control group and before intervention (P<0.05). The C-DMSES score in each dimension in the observation group after intervention was higher than that in the control group and before intervention (P<0.05). After intervention, the scores of treatment, physiology, psychology and social relationship in DSQL in the observation group were significantly lower than those in the control group and before intervention (P<0.05). The incidence rate of perioperative complications in the observation group (10.42%) was significantly lower than that in the control group (31.25%) (P<0.05). Conclusion Goal-oriented diversified nursing intervention can effectively control the blood glucose indicators, improve self-management ability, reduce the incidence of perioperative complications and adverse neonatal outcomes.
ABSTRACT
Abstract Objective Evaluate the prevalence of macrosomic newborns (birth weight above 4000 grams) in a high-risk maternity from 2014 to 2019, as well as the maternal characteristics involved, risk factors, mode of delivery and associated outcomes, comparing newborns weighing 4000-4500 grams and those weighing above 4500 grams. Methods This is an observational study, case-control type, carried out by searching for data in hospital's own system and clinical records. The criteria for inclusion in the study were all patients monitored at the service who had newborns with birth weight equal than or greater than 4000 grams in the period from January 2014 to December 2019, being subsequently divided into two subgroups (newborns with 4000 to 4500 grams and newborns above 4500 grams). After being collected, the variables were transcribed into a database, arranged in frequency tables. For treatment and statistical analysis of the data, Excel and R software were used. This tool was used to create graphs and tables that helped in the interpretation of the results. The statistical analysis of the variables collected included both simple descriptive analyzes as well as inferential statistics, with univariate, bivariate and multivariate analysis. Results From 2014 to 2019, 3.3% of deliveries were macrosomic newborns. The average gestational age in the birth was 39.4 weeks. The most common mode of delivery (65%) was cesarean section. Diabetes mellitus was present in 30% of the deliveries studied and glycemic control was absent in most patients. Among the vaginal deliveries, only 6% were instrumented and there was shoulder dystocia in 21% of the cases. The majority (62%) of newborns had some complication, with jaundice (35%) being the most common. Conclusion Birth weight above 4000 grams had a statistically significant impact on the occurrence of neonatal complications, such as hypoglycemia, respiratory distress and 5th minute APGAR less than 7, especially if birth weight was above 4500 grams. Gestational age was also shown to be statistically significant associated with neonatal complications, the lower, the greater the risk. Thus, macrosomia is strongly linked to complications, especially neonatal complications.

SUMMARY OBJECTIVE: The aim of this study was to compare the correlation of maternal visceral adiposity with sonographic variables related to fetal biometry in the second trimester of pregnancy in mothers who were previously obese versus nonobese and gestational diabetic versus nondiabetic. METHODS: This cross-sectional study included 583 pregnant women who received prenatal care between October 2011 and September 2013 at the Instituto de Medicina Integral Prof. Fernando Figueira, northeast of Brazil. Maternal visceral adiposity was measured by ultrasound examination at the same time as fetal biometry. Gestational age was 14.9±3.2 weeks. The correlation between maternal visceral adiposity and fetal biometric variables was evaluated using Pearson's correlation coefficient. Among the groups, the correlation coefficients were compared using Fisher's Z-test. This test was also used to evaluate the null hypothesis of correlation coefficients between pairs of variables. RESULTS: Maternal visceral adiposity positively correlated with fetal abdominal circumference, estimated fetal weight, head circumference, femur length, and biparietal diameter in pregnant women with obesity, nonobesity, gestational diabetes, and nondiabetes, but the correlation coefficients were statistically similar among the groups. CONCLUSION: Maternal visceral adiposity positively correlated with fetal biometry in the second trimester of pregnancy in the same manner in pregnant women previously obese and nonobese, as well as in pregnant women with gestational diabetes and nondiabetes.
ABSTRACT
ABSTRACT Objective: This study aims to evaluate the impact of morning-evening preference in pregnancy outcomes in gestational diabetes mellitus (GDM). Materials and methods: This is a prospective cohort study of 2nd-3rd trimester GDM outpatient care in Fortaleza, Brazil (2018-2020). Eveningness was defined by the Horne-Östberg Morningness-Eveningness-Questionnaire (MEQ ≤ 41). Furthermore, we obtained a 7-day actigraphic register. Subjective sleep quality, daytime somnolence, insomnia, fatigue and depressive symptoms were also evaluated. Associations with pregnancy outcomes were investigated. Results: Among 305 patients with GDM, evening preference was found in 21 (6.9%). Patients with evening preference had worse sleep quality (p < 0.01), greater severity of insomnia (p < 0.005), fatigue (p < 0.005) and depressive symptoms (<0.009). Evening chronotype was associated with preeclampsia [p = 0.01; OR = 0.27; CI 0.09-0.79] and a greater need for admission to a neonatal intensive care unit (NICU) [p = 0.02; OR = 0.23; CI .0.06-0.80]. A lower MEQ score confirmed an association with preeclampsia [p = 0.002; OR = 0.94; CI 0.90-0.97] and this was maintained after controlling for age, arterial hypertension, sleep quality, fatigue and depressive symptoms [p < 005; OR = 0.91; CI 0.87-0.95]. Conclusion: In GDM, patients with evening preference had worse sleep quality, more insomnia, fatigue, and depressive symptoms. Furthermore, eveningness was independently associated with preeclampsia. These results indicate the important role of eveningness in adverse pregnancy outcomes.
ABSTRACT
SUMMARY OBJECTIVE: The aim of this study was to compare the efficiency of fetal thymic-thoracic ratio and fetal thymus transverse diameter measurements in gestational diabetes mellitus. METHODS: Fetal thymic-thoracic ratio and fetal thymus transverse diameter were assessed in 360 pregnant women. Patients were examined in two groups: 180 gestational diabetes mellitus (study group) and 180 healthy pregnant women (control group). RESULTS: There were no statistically significant differences between the cases with gestational diabetes mellitus and the control group in terms of fetal thymus transverse diameter; however, the fetal thymic-thoracic ratio was found to be significantly lower in cases with gestational diabetes mellitus compared to that in the control group (p<0.001). CONCLUSION: The fetal thymic-thoracic ratio is superior to the fetal thymus transverse diameter in evaluating the fetal thymus size.
ABSTRACT
Objective:To conduct a scoping review of health behavior-related assessment tools for pregnant women with gestational diabetes mellitus (GDM).Methods:A total of 6 Chinese and English databases, including CNKI, Wanfang Database, China Biomedical Literature Database, PubMed, Web of Science Core set and Embase, were systematically searched by the terms of “gestational diabetes mellitus”，“health behavior”，“assessment”. The relevant contents of GDM health behavior-related assessment tools were retrieved for systematic analysis, and the results were normalized reported. The search period was from the establishment of the databases to February 1, 2023.Results:A total of 2 657 literatures were retrieved, and 41 literatures were finally included after screening, including 16 literatures on the development and verification of assessment tools, 2 literatures on localization of assessment tools, and 23 literatures on the application of the assessment tools. A comprehensive analysis was conducted on 18 assessment tools, including 16 original assessment tools and 2 localized assessment tools, spanning the years 1987 to 2020. The assessment content covered dietary behavior, physical activity behavior, medication adherence, blood glucose monitoring behavior, treatment adherence, self-management behavior, and health-promoting lifestyles. Among them, 7 assessment tools were validated for reliability and/or validity in pregnant women with GDM. Among the 23 studies that covered the implication of the assessment tools, the Pregnancy Physical Activity Questionnaire and Health-Promoting Lifestyle Ⅱ were the most commonly utilized tools for assessing health behaviors in pregnant women with GDM.Conclusions:There is a wide variety of assessment tools related to health behaviors in pregnant women with GDM, and the assessment content is relatively rich. However, most of the assessment tools have not been validated for their reliability and validity within the GDM population, limiting their clinical application and promotion.
ABSTRACT
Objective:To analyze the clinical features, prevention, and treatment of diabetic ketoacidosis (DKA) in pregnancy.Methods:Clinical features, treatment, and pregnancy outcomes of ten pregnant patients diagnosed with DKA and treated at Peking University First Hospital from January 2004 to December 2021 were analyzed retrospectively using descriptive statistical analysis.Results:DKA was found in two cases in the first trimester, three in the second trimester, and five in the third trimester, respectively. Six had type 1 diabetes (including two patients with fulminant type 1 diabetes) and four patients had type 2 diabetes. Only two cases received regular pregnancy examinations, and two began prenatal care in the second trimester. The other six cases neither had prenatal examination nor regular examination. Infection, pancreatitis, and preeclampsia occurred in six, two, and one case, respectively, and among them, four had urinary system infection. Laboratory examination showed that the average pH, blood glucose, and glycated hemoglobin A1c (HbA1c) at onset were 7.06±0.16, (23.7±2.6) mmol/L and (9.2±0.8)%. All patients had different degrees of electrolyte disorder and tested positive for urine ketone bodies. After rehydration, glucose-lowering, and correction of electrolyte disorder, the acidosis was relieved, and the ketone bodies turned negative in all patients. There was no maternal death. The fetal loss occurred in five cases, including one with intrauterine fetal death in late pregnancy, one with embryo arrest in early pregnancy, one with unavoidable abortion, and two terminated on maternal request. The remaining three were term labor and two were preterm labor.Conclusions:The leading cause of DKA in pregnancy is poor control of diabetic blood glucose, followed by infection. Once DKA is complicated during pregnancy, the outcome of the mother and her baby is poor. Its occurrence should be actively prevented. For women with fulminant type 1 diabetes, DKA is easier to occur, and the prognosis is poorer, so strict management and follow-up should be warranted.

Objective:To investigate the level of plasma Betatrophin in pregnant women with gestational diabetes mellitus (GDM) and its correlation with the control of blood glucose.Methods:Forty-five pregnant women with GDM(GDM group) who received regular obstetric examinations in the Huaihua First People′s Hospital from July 2019 to January 2021 and 50 pregnant women with normal glucose tolerance (NGT) (NGT group) during the same period were enrolled in this study. Blood glucose and blood lipid indicators were collected, plasma Betatrophin level was detected, Logistic regression analysis was used to screen the influencing factors of blood glucose control effect, the pregnancy outcome was followed up, the predictive value of Betatrophin level in blood glucose control and pregnancy outcome was evaluated by receiver operating characteristic (ROC) curve.Results:The levels of systolic blood pressure, diastolic blood pressure, fasting plasma glucose (FPG), 2 h postpartum blood glucose (2 h PG), glycosylated hemoglobin (HbA 1c), fasting insulin (FINS), 2 h postprandial insulin (2 h FINS), insulin resistance index (HOMA-IR), low density lipoprotein cholesterin (LDL-C) and plasma Betatrophin in the GDM group were higher than those in the NGT group, and insulin function index (HOMA-β) and high density lipoprotein cholesterin (HDL-C) were lower than those in the NGT group ( P<0.05). Pearson correlation analysis showed that plasma Betatrophin level was positively correlated with HbA 1c and HOMA-IR in pregnant women and the GDM group ( r = 0.310, 0.314, 0.341, 0.333; P<0.05). In the GDM group, 12 patients with poor glucose control, 33 patients with good glucose control, the FPG, HbA 1c, HOMA-IR and plasma Betatrophin levels in poor glucose control patients were higher than those in good glucose control patients, HOMA-β was lower than that in the good glucose control patients: (5.82 ± 0.98)mmol/L vs. (5.04 ± 1.11) mmol/L, (9.78 ± 2.15)% vs. (8.22 ± 1.41)%, 2.71 ± 0.56 vs. 2.24 ± 0.48, (1 345.12 ± 256.32) ng/L vs. (1 165.10 ± 217.41) ng/L, 144.15 ± 22.71 vs. 158.63 ± 20.26, there were statistical differences ( P<0.05). The area under the curve of plasma Betatrophin level to predict the effect of blood glucose control was 0.775. A total of 8 pregnant women with GDM had poor pregnancy outcome, and the area under the curve predicted pregnancy outcome by plasma Betatrophin level was 0.728. Conclusions:The level of plasma Betatrophin in patients with GDM is closely related to the degree of insulin resistance and the effect of blood glucose control, and can provide some reference for clinical evaluation and therapeutic effect prediction.
ABSTRACT
Objective:To investigate the clinical efficacy of vitamin D drops combined with insulin aspart in the treatment of gestational diabetes mellitus (GDM), and the effect of vitamin D drops on the serum levels of 1, 25 dihydroxyvitamin D 3 [1, 25(OH) 2D 3] and retinol binding protein 4 (RBP4). Methods:A total of 94 GDM patients admitted to the Baoding Second Central Hospital from March 2019 to March 2021 were selected and randomly divided into an observation group and a control group with 47 cases each using a random number table method. The control group received subcutaneous injection of insulin aspartate for treatment, while the observation group received oral vitamin D drops for treatment. After 4 weeks of continuous treatment, the blood glucose control effect and adverse reactions were observed in both groups. The glucose metabolism indicators of the two groups were compared before and after treatment, including fasting blood glucose (FPG), 2-hour postprandial blood glucose (2-hour PG), insulin resistance index (HOMA-IR), and pancreatic islets β Cell Function Index (HOMA-β) and serum levels of 1, 25(OH) 2D 3, RBP4, lipoprotein related phospholipase A2 (Lp-PLA2), and vascular cell adhesion molecule-1 (VCAM-1). All patients were followed up until the end of pregnancy, and Statistical analysis was conducted on the adverse outcomes of two groups of mothers and infants. Results:The time to reach the standard for FPG and 2-hour PG in the observation group, as well as the time for both to reach the standard were significantly shorter than those in the control group (all P<0.05). There was no statistically significant difference in the incidence of dawn phenomenon and hypoglycemia between the observation group and the control group (all P>0.05). After treatment, FPG and 2-hour PG in both groups were significantly reduced compared to those before treatment (all P<0.05); However, after treatment, there was no statistically significant difference between the groups (all P>0.05). Compared with before treatment, HOMA-IR in both groups significantly decreased (all P<0.05), All HOMA- β significantly increased (all P<0.05); And the improvement was more significant in the observation group (all P<0.05). After treatment, the serum levels of 1, 25(OH) 2D 3 in the observation group significantly increased compared to that before treatment ( P<0.05), but there was no significant change in the control group before and after treatment ( P>0.05). After treatment, the levels of serum RBP4, Lp-PLA2, and VCAM-1 in both groups significantly decreased compared to those before treatment (all P<0.05); After treatment, the serum levels of RBP4, Lp-PLA2, and VCAM-1 in the observation group were lower than those in the control group (all P<0.05). The incidence of adverse maternal and neonatal outcomes in the observation group was 14.9%(7/47) and 10.6%(5/47), respectively, which were lower than those in the control group [34.0%(16/47) and 27.7%(13/47)] (all P<0.05). There were 8 cases of hypoglycemia in 94 patients (3 in the observation group and 5 in the control group), and no other adverse events occurred. Conclusions:The combination of vitamin D drops and insulin aspartate in the treatment of GDM can safely, effectively, quickly, and steadily control patients′ blood sugar, improve IR and pancreatic islets β The effect of cell function on reducing the incidence of adverse maternal and fetal outcomes may be related to increasing serum 1, 25(OH) 2D 3 levels and down-regulating the expression levels of serum RBP4, Lp-PLA2, and VCAM-1.
ABSTRACT
Objective:To investigate the influencing factors of urinary tract infection in pregnant women with diabetes and the distribution characteristics of pathogens in the middle urinary tract.Methods:A total of 220 patients with gestational diabetes who visited the Second People′s Hospital of Lianyungang City from December 2018 to December 2021 were selected as the study subjects, and the incidence of urinary tract infection was counted. According to the diagnosis results of urinary tract infection, they were divided into infected group and uninfected group. The infected group took the middle urine for pathogen culture, and the resistance rate of main gram-negative bacteria to antibiotics was analyzed; Logistic regression model was used to analyze the influencing factors of urinary tract infection in pregnant women with diabetes.Results:There were 32 cases of urinary tract infection in 220 patients with gestational diabetes, and the infection rate was 14.55%(32/220). 43 strains of pathogenic bacteria were identified, mainly gram-negative bacilli [72.09%(31/43)], followed by gram-positive cocci [20.93%(9/43)] and fungi [6.98%(3/43)]. Amongthe main gram-negative bacteria, escherichia coli had a high resistance rate to ampicillin and levofloxacin, while Klebsiella pneumoniae had a high resistance rate to ampicillin and cefazolin; There were significant differences between the infected group and the non infected group in age, hospital stay, personal urinary tract infection history, pregnancy sexual life history, use of antibiotics, fasting blood sugar, serum albumin, and glycated hemoglobin (all P<0.05); Multivariate logistic regression results showed that personal history of urinary tract infection, sexual life during pregnancy, non-standard use of antibiotics, serum albumin<30 g/L, glycated hemoglobin ≥7%, and fasting blood sugar ≥8.5 mmol/L were independent risk factors for urinary tract infection in pregnant diabetes patients (all P<0.05). Conclusions:There is a high incidence of urinary tract infection in patients with gestational diabetes, and the risk factors are complex. Gram negative bacilli are the main pathogenic bacteria. Antibacterial drugs can be reasonably selected for intervention according to drug sensitivity test in clinical practice.
ABSTRACT
Objective:To investigate the effects of birth intervals on maternal and infant outcomes in pregnant women with gestational diabetes mellitus (GDM).Methods:This retrospective study recruited 445 pregnant women with GDM who received prenatal examinations and delivered in Peking University First Hospital-Ningxia Women Children's Hospital from January 2020 to December 2021. Based on the birth interval classification standard recommended by WHO and the American College of Obstetricians and Gynecologists, these subjects were divided into three groups: shorter group (<18 months, n=69), normal group (18-59 months, n=213) and longer group (≥60 months, n=163). Analysis of variance, Chi-square test, and multivariate logistic regression model were used for statistical analysis. Results:There were statistically significant differences in the maternal age at this and previous pregnancy [(30.6±4.1), (30.8±3.8) vs (32.7±3.7) years; (22.7±2.4), (26.3±2.9) vs (29.9±4.1) years] and the incidence of oligohydramnios [10.1% (7/69), 1.9% (4/213) vs 3.1% (5/163)] and preterm birth [14.5% (10/69), 5.2% (11/213) vs 1.8% (3/163)] between the shorter, normal, and longer groups (all P<0.05). After adjusting for confounding factors in the present pregnancy, the risks of oligohydramnios, preterm birth, and low birth weight increased in the shorter group [ OR (95% CI): 4.73 (1.75-12.85), 5.54 (1.37-22.42) and 9.54 (3.05-29.82), all P<0.05] and so did the risk of postpartum hemorrhage in the longer group [ OR (95% CI): 4.45 (1.72-11.49), P<0.05]. Conclusions:Both longer and shorter birth intervals can affect maternal and infant outcomes of GDM patients. Postpartum healthcare should be strengthened for GDM patients who desire more children to help them maintain an appropriate birth interval, thus promoting maternal and infant health.
ABSTRACT
Ferroptosis, a new form of programmed cell death, could be regulated by lipid metabolism, amino acid metabolism, and iron metabolism. Ferroptosis is closely related to human physiological mechanisms and involved in the development and progression of multiple diseases. More and more researchers have found that ferroptosis also plays a vital role in pregnancy-related disorders such as preeclampsia, gestational diabetes, and miscarriage. However, the mechanisms have not yet been fully understood. This article reviews the progress in ferroptosis in pregnancy-related diseases to provide new directions for scientific research and clinical treatment.
ABSTRACT
Gestational diabetes mellitus (GDM) is a serious threat to maternal and infant health. However, the unclear etiology and pathogenesis of GDM is the harrier of clinical intervention. In recent years, the relationship between inflammation and GDM has been widely concerned, but the conclusions are inconsistent. This paper summarizes the research progress on the association between inflammation-related indicators and GDM, in order to provide a basis for the diagnosis, treatment, or prophylaxis of GDM.
