ABSTRACT
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
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
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
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 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 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
ABSTRACT OBJETIVE To evaluate the association between the use of iron salts during the first two trimesters of gestation in non-anemic women and the development of gestational diabetes mellitus. METHODS The study used maternal data from the 2015 Pelotas Birth Cohort. All non-anemic women at the 24th week of gestation (n = 2,463) were eligible for this study. Gestational diabetes mellitus was self-reported by women. Crude and adjusted logistic regression were performed considering level of significance = 0.05. RESULTS Among the women studied, 69.7% were exposed to prophylactic iron supplementation in the first two trimesters of gestation. The prevalence of gestational diabetes mellitus among those exposed was 8.7% (95%CI: 7.4-10.1) and 9.3% (95%CI: 7.4-11.6) among those who were not exposed. Iron supplementation was not associated with increased risk of gestational diabetes mellitus in crude (OR = 0.9; 95%CI: 0,7-1,3) and adjusted analysis (OR = 1.1; 95%CI :0,8-1,6). CONCLUSIONS The results suggest that routine iron use in non-anemic pregnant women does not increase the risk of developing gestational diabetes. This evidence supports the existing national and international guidelines, in which prophylactic iron supplementation is recommended for all pregnant women as soon as they initiate antenatal care in order to prevent iron deficiency anemia.

Resumen OBJETIVO: Describir la prevalencia de diabetes gestacional e hipertensión arterial en pacientes embarazadas con obesidad pregestacional. MATERIALES Y MÉTODOS: Estudio retrospectivo, transversal y descriptivo llevado a cabo en mujeres embarazadas con diagnóstico previo de obesidad (índice de masa corporal superior a 29.99) y con control prenatal. Parámetros evaluados: estilo de vida (alimentación, actividad física, consumo de alcohol, tabaco o alguna toxicomanía) y características físicas, clínicas y bioquímicas durante el embarazo actual por trimestre (índice de masa corporal, glucosa, presión arterial sistólica y diastólica). El diagnóstico de diabetes gestacional se estableció mediante una prueba de tolerancia a la glucosa entre las semanas 24 y 28 de embarazo. La hipertensión gestacional se diagnosticó por cifras de presión arterial mayores e iguales a 140-90 mmHg a partir de la semana 20 de embarazo y en ausencia de proteinuria. El análisis estadístico incluyó porcentajes, promedios e intervalos de confianza. RESULTADOS: La prevalencia de diabetes gestacional en embarazadas con obesidad fue 13.7% (IC95%: 9.6 a 17.9) y la de hipertensión gestacional en embarazadas con obesidad 7.4% (IC95%: 4.3 a 10.6). CONCLUSIÓN: La obesidad es un factor conocido de riesgos, en particular de diabetes e hipertensión en el embarazo. Su alta prevalencia hace necesario implementar campañas de prevención que favorezcan su reducción.
Abstract OBJECTIVE: To describe the prevalence of gestational diabetes and arterial hypertension in pregnant patients with pre-pregnancy obesity. MATERIALS AND METHODS: Retrospective, cross-sectional and descriptive study in pregnant women with a diagnosis of obesity prior to pregnancy (body mass index greater than 29.99) and with prenatal care. The sample size was 269 pregnant women. Lifestyle (diet, physical activity, alcohol, tobacco or drug addiction) and physical, clinical and biochemical characteristics during the current pregnancy were evaluated by gestational trimester (body mass index, glucose, systolic and diastolic blood pressure). The diagnosis of gestational diabetes was established by a glucose tolerance test between the 24th and 28th week of gestation and gestational hypertension was diagnosed by blood pressure figures greater than or equal to 140/90 mmHg from the 20th week of gestation and in the absence of proteinuria. Statistical analysis included percentages, means, and confidence intervals. RESULTS: The prevalence of gestational diabetes in obese pregnant women was 13.7% (95%CI: 9.6-17.9) and the prevalence of gestational hypertension in obese pregnant women was 7.4% (95%CI: 4.3-10.6). CONCLUSION: Obesity is a known risk factor, particularly for diabetes and hypertension in pregnancy. Its high prevalence makes it necessary to implement prevention campaigns to reduce it.
ABSTRACT
ABSTRACT Objective This study aims to determine the effect of fruit consumption time on blood glucose regulation in pregnant women with gestational diabetes. Methods The study was carried out with 64 volunteer participants diagnosed with gestational diabetes. Participants who were directed to the Department of Nutrition and Dietetics were divided into two groups according to the order of application; Group 1 was included in the nutrition treatment program for a week, consuming fruit for the main meal and Group 2 for the snack. During this process, the participants were applied a personalized nutrition plan that was adjusted equally for macronutrients of all meals containing isocaloric 3 main and 4 snacks. In this process, blood glucose values were measured six times a day by the participants and the blood glucose results of both groups before starting the nutrition therapy and on the seventh day after starting the medical nutrition therapy were compared. Results The mean age of the women participating in the study was 33.50±4.95 years and 32.28±5.18 years for the 1st and 2nd groups, respectively, and the groups were similar in terms of anthropometric measurements. The post-diet average of postprandial blood glucose levels in the morning within each group dropped from 180mg/d to 115mg/dL (p<0,001) for Group 1 and from 185mg/dL to 110mg/dL (p<0,001) for Group 2. There was a decrease in the fasting plasma glucose and postprandial blood glucose levels measured in the morning, noon and evening before and after the medical nutrition therapy of the groups, but no statistically significant difference was found between the groups (p>0.05). All participants on the gestational diabetes diet had normal blood sugar levels without the need for insulin. A statistically significant decrease was observed in the postprandial blood glucose-fasting plasma glucose difference levels of the pregnant women in the group that consumed fruit for snacks (Group 2) on the seventh day of the study (p<0,001). There was no significant difference in the pre-diet and post-diet morning fasting plasma glucose values of both groups (p>0,05). Conclusion This study found that medical nutrition therapy in pregnant women with gestational diabetes led to a decrease in blood glucose levels, but consuming fruits as a snack or at the main meal did not make a significant difference on fasting plasma glucose and postprandial blood glucose. It was concluded that the type and amount of carbohydrates consumed daily in gestational diabetes are determinative on blood glucose level.
RESUMO Objetivo O objetivo deste estudo é determinar o efeito do tempo de consumo de fruta na regulação da glucose no sangue em mulheres grávidas com diabetes gestacional. Métodos Este estudo foi realizado com 64 participantes voluntários diagnosticados com diabetes gestacional. Os participantes que foram encaminhados para o Departamento de Nutrição e Dietética foram divididos em dois grupos, de acordo com a ordem da sua aplicação. O grupo 1 foi incluído no programa de tratamento médico nutricional durante uma semana, consumindo fruta para a refeição principal e o grupo 2 para os lanches. Neste processo, foi aplicado aos participantes um plano de nutrição personalizado, com isocalórico, 3 refeições principais e 4 lanches, os macronutrientes de todas as refeições foram ajustados igualmente. Neste processo, os valores de glicemia foram medidos seis vezes por dia pelos participantes, e foram comparados os resultados da glicemia de ambos os grupos antes de se iniciar a terapia nutricional médica e no sétimo dia após o início da terapia nutricional médica. Resultados A idade média das mulheres que participaram no estudo foi de 33,50±4,95 e 32,28±5,18 anos para o 1º e 2º grupos, respetivamente, e não houve diferença entre os grupos em termos de medidas antropométricas. A glicemia média pós-prandial de manhã após terapia nutricional médica dentro dos grupos variou entre 180mg/d a 115mg/dL (p<0,001) para o Grupo 1, e de 185mg/dL a 110mg/dL para o Grupo 2 (p<0,001). Houve uma diminuição nos níveis de glicemia em jejum e glicemia média pós-prandial medidos de manhã, meio-dia e noite antes e depois da terapia nutricional médica dos grupos, mas não houve diferença estatisticamente significativa entre os grupos (p>0,05). Os níveis de açúcar no sangue de todos os participantes na dieta diabetes gestacional baixaram para níveis normais sem necessidade de terapia com insulina. Uma diminuição estatisticamente significativa foi observada no sétimo dia do estudo nos níveis de diferença do glicemia média pós-prandial-glicemia em jejum das mulheres grávidas do grupo que consumiram fruta como aperitivo (Grupo 2). (p<0.001). Não houve diferença significativa nos valores de glicemia em jejum matinal de ambos os grupos antes e depois da dieta (p>0,05). Conclusão Como resultado deste estudo, verificou-se que a terapia nutricional levou a uma diminuição do açúcar no sangue em mulheres grávidas com diabetes gestacional, mas o consumo de fruta como lanche ou refeição principal não fez uma diferença significativa no jejum e na glucose do sangue pós-prandial. Concluiu-se que o tipo e a quantidade de hidratos de carbono consumidos diariamente na diabetes gestacional são determinantes para o nível de glicose no sangue.

Pathological insulin resistance (IR) is closely related to gestational diabetes mellitus (GDM) and adverse pregnancy outcomes in women with GDM. Increasing studies have investigated the efficacy of IR indices, such as quantitative insulin sensitivity index, homeostasis model assessment of insulin resistance, triglyceride-glucose index and sex hormone-binding globulin, in predicting GDM and related complications in recent years. This article reviews the research progress in the above topics.
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.
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
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
ABSTRACT Introduction: Gestational Diabetes is a group of metabolic disorders that result in glucose intolerance during pregnancy. Among the range of treatments are diet, continuous use of medication, and psychological monitoring. Since it is a multidisciplinary treatment, a proper protocol is vital for a favorable outcome. In addition, there are questions about the benefits of physical activity as a complementary therapy. Objective: To verify the impact of adding exercise to the hospital protocol for patients with gestational diabetes, both on the risks of type 2 diabetes in pregnant women and on the obesity of their offspring. Methods: Sixty pregnant women diagnosed with Gestational Diabetes were randomly divided into control and intervention groups. Both groups received specific treatment and intervention, and the experimental group practiced controlled moderate-intensity physical activity (125-146bpm). Morning blood samples were collected from both groups to check fasting glucose and insulin levels, indicators of lipid metabolism, low and high-density lipoprotein cholesterol, apolipoprotein B. The Brog scale measured the fatigue level. In addition, the premature rupture of membranes, postpartum hemorrhage, neonatal asphyxia, macrosomia, and others was checked. Results: The peripheral blood total cholesterol levels were 5.93, 5. 38, low-density lipoprotein cholesterol levels were 2.95 before versus 2.64 after, and apolipoprotein B levels were 1.84 versus 1.59 in the control group, high-density lipoprotein cholesterol content increased from 1.74 to 1.88, blood cholesterol, and apolipoprotein B levels after the intervention in the experimental group were lower than those in the control group, with an elevation of high-density lipoprotein cholesterol. Conclusion: Aerobic exercise proved to be more appropriate for patients with gestational diabetes in the later stages of pregnancy and may also be adapted for bedridden patients refractory to traditional drugs. Evidence Level II; Therapeutic Studies - Investigating the result.
RESUMO Introdução: O Diabetes Gestacional é um grupo de desordens metabólicas que resultam na intolerância à glicose durante a gravidez, dentre o leque de tratamentos está a dieta, o uso continuo de medicamentos, e acompanhamento psicológico. Por ser um tratamento multidisciplinar, é importante que haja um protocolo adequado para um desfecho favorável. Há questionamentos quanto aos benefícios de atividades físicas como terapia complementar. Objetivo: Verificar o impacto da adição de exercícios ao protocolo hospitalar para pacientes com diabetes gestacional, tanto nos riscos de diabetes tipo 2 em grávidas quanto na obesidade de seus descendentes. Métodos: Sessenta mulheres grávidas que foram diagnosticadas com Diabetes Gestacional foram aleatoriamente divididas em grupos controle e intervenção. Ambos grupos receberam tratamento e intervenção específicos e o grupo experimental praticou atividade física de intensidade moderada controlada (125-146bpm). Amostras de sangue em jejum matinal foram coletados em ambos os grupos para verificar níveis de glicose e insulina em jejum, indicadores de metabolismo lipídico, colesterol lipoproteico de baixa e alta densidade, apolipoproteína B. Verificou-se também o nível de fadiga pela escala Brog, ruptura prematura de bolsa, hemorragia pós-parto, asfixia neo-natal, macrossomia entre outros. Resultados: Os níveis de colesterol total no sangue periférico foram de 5,93, 5.38, os níveis de colesterol lipoproteico de baixa densidade foram 2,95 antes contra 2,64 depois e os níveis de apolipoproteína B foram 1,84 contra 1,59 no grupo controle, o conteúdo de colesterol lipoproteico de alta densidade aumentou de 1,74 para 1,88, os níveis de colesterol, e apolipoproteína B sanguíneos depois da intervenção no grupo experimental foram menores que os do grupo controle, com elevação do colesterol lipoprotéico de alta densidade. Conclusão: O exercício aeróbico mostrou-se mais adequado para pacientes com diabetes gestacional nos estágios posteriores da gravidez, podendo ser adaptado inclusive para as pacientes acamadas refratárias aos fármacos tradicionais.

Resumen Introducción: La diabetes gestacional es un grupo de trastornos metabólicos que dan lugar a una intolerancia a la glucosa durante el embarazo. Entre la gama de tratamientos se encuentra la dieta, el uso continuado de medicamentos y el seguimiento psicológico. Al tratarse de un tratamiento multidisciplinar, es importante contar con un protocolo adecuado para obtener un resultado favorable. Existen dudas sobre los beneficios de la actividad física como terapia complementaria. Objetivo: Comprobar el impacto de añadir el ejercicio al protocolo hospitalario para pacientes con diabetes gestacional, tanto en los riesgos de diabetes tipo 2 en las mujeres embarazadas como en la obesidad de su descendencia. Métodos: Sesenta mujeres embarazadas a las que se les diagnosticó diabetes gestacional fueron divididas aleatoriamente en grupos de control y de intervención. Ambos grupos recibieron un tratamiento y una intervención específicos y el grupo experimental practicó una actividad física controlada de intensidad moderada (125-146bpm). Se tomaron muestras de sangre en ayunas por la mañana de ambos grupos para comprobar los niveles de glucosa e insulina en ayunas, los indicadores del metabolismo de los lípidos, el colesterol de lipoproteínas de baja y alta densidad, la apolipoproteína B. También se comprobó el nivel de fatiga según la escala de Brog, la rotura prematura de bolsa, la hemorragia posparto, la asfixia neonatal y la macrosomía, entre otros. Resultados: Los niveles de colesterol total en sangre periférica fueron de 5,93, 5. 38, los niveles de colesterol de lipoproteínas de baja densidad eran de 2,95 antes frente a 2,64 después y los niveles de apolipoproteína B eran de 1,84 frente a 1,59 en el grupo de control, el contenido de colesterol de lipoproteínas de alta densidad aumentó de 1,74 a 1,88, el colesterol en sangre y los niveles de apolipoproteína B después de la intervención en el grupo experimental fueron inferiores a los del grupo de control, con una elevación del colesterol de lipoproteínas de alta densidad. Conclusión: El ejercicio aeróbico resultó ser más apropiado para las pacientes con diabetes gestacional en las últimas fases del embarazo, y puede adaptarse incluso a las pacientes encamadas y refractarias a los fármacos tradicionales. Nivel de evidencia II; Estudios terapéuticos - Investigación de resultados.
ABSTRACT
Gestational diabetes mellitus (GDM) can lead to adverse maternal and infant outcomes, and the incidence of GDM is increasing with the high prevalence of overweight and obesity in women of reproductive age. In recent years, the prevalence of GDM in my country has been increasing. Obstructive sleep apnea hypopnea syndrome (OSAHS) can increase the risk of type 2 diabetes, that′s why improve sleep apnea can effectively improve the state of glucose metabolism. Most studies have shown that OSAHS is associated with an increased risk of GDM, but there are still some studies that have different results, and whether continuous positive airway pressure (CPAP) in pregnant women with OSAHS can improve glucose metabolism is still inconclusive. This article systematically reviewed the research progress of the relationship between OSAHS and GDM, and also reviewed whether CPAP can improve the glucose metabolism status of patients with GDM.
ABSTRACT
Objective:To analyze the risk factors of postpartum type 2 diabetes (T2DM) in patients with family history of diabetes mellitus with gestational diabetes mellitus (GDM).Methods:From January 2017 to January 2019, 275 patients with GDM and family history of diabetes were selected. According to the occurrence of postpartum T2DM, the patients were divided into postpartum normal group (207 cases) and postpartum disease group (68 cases). The clinical data of the two groups were compared, and the independent risk factors of postpartum T2DM were analyzed by logistic regression, and a line chart prediction model was constructed. Receiver operating characteristic (ROC) curve and calibration curve were used to evaluate the predictive ability of the model. X-tile software was used to obtain the integral truncation value of the line graph model, and survival curve was drawn and internal verification was carried out.Results:Of 275 GDM patients, 68 had T2DM after delivery, with a incidence rate of 24.73%. There were significant differences between the two groups in age, body mass index (BMI) before pregnancy, weight gain during pregnancy, fasting blood glucose during pregnancy and glycosylated hemoglobin during pregnancy (all P<0.05). There was no significant difference in pregnancy outcome between the two groups ( P>0.05). Age≥30 years, high pre-pregnancy BMI, weight gain≥6 kg during pregnancy, fasting blood glucose>5.8 mmol/L during pregnancy, and glycosylated hemoglobin>5.2% during pregnancy were independent risk factors for postpartum T2DM in GDM patients with diabetes family history (all P<0.05). The nomogram model predicted that the C-index value of postpartum T2DM was 0.912 (95% CI: 0.854-0.960), and the area under the ROC curve was 0.799 (95% CI: 0.742-0.856), with good discrimination; The calibration curve indicated that the accuracy of the model was good. According to the integral cutoff value of the line chart model, the probability of postpartum T2DM in GDM patients with family history of diabetes was divided into three groups: low (≤67.24 points), medium (>67.24 points and ≤129.82 points) and high-risk groups. The incidence rate of postpartum T2DM were 13.71%, 29.29% and 59.62%, respectively, with statistical significance (all P<0.05). Conclusions:Age≥30 years old, high pre-pregnancy BMI, pregnancy weight gain≥6 kg, pregnancy fasting blood glucose>5.8 mmol/L and pregnancy glycosylated hemoglobin>5.2% were independent risk factors for postpartum T2DM in GDM patients with family history of diabetes.
ABSTRACT
Gestational diabetes mellitus (GDM) can lead to adverse pregnancy outcomes and epigenetic changes in offspring due to exposure to a high-glucose intrauterine environment, resulting in related short- and long-term complications. MicroRNA (miRNA)-mediated post-transcriptional regulation, a gene expression regulation mechanism that has gained much attention in recent years, may play a role in morbidity in offspring born to mothers with GDM, such as macrosomia, heart development, neurodevelopment, and long-term metabolic diseases. This article reviews the progress of miRNA in GDM and associated complications in the offspring.
ABSTRACT
Objective:To explore the application and effect of artificial intelligence technology in perinatal management of gestational diabetes mellitus.Methods:240 pregnant women with gestational diabetes diagnosed during 24-26 weeks of pregnancy in Changsha Maternal and Child Health Hospital were prospectively selected and randomly divided into control group (120 cases) and observation group (120 cases). The control group used the traditional management mode for nutritional management, and the observation group used AI technology for nutritional management. The weight gain, blood glucose control level, insulin use, pregnancy complications, pregnancy outcome and other indicators of the two groups were compared.Results:(1) Monitoring indicators during pregnancy: there was no significant difference in weight gain between the two groups ( P>0.05). The proportion of weight gain in the appropriate range in the observation group was significantly higher than that in the control group ( P<0.05); The prevalence of full-term anemia, insulin use rate and the incidence of blood glucose exceeding the control standard in the observation group were significantly higher than those in the control group (all P<0.05). (2) Pregnancy outcome: there was no significant difference in the incidence of gestational hypertension, cesarean section, fetal growth restriction, premature delivery and neonatal hypoglycemia between the two groups (all P>0.05); The incidence of conversion to cesarean section, macrosomia, neonatal blood glucose <2.6 mmol/L, mild asphyxia and admission to neurosurgical intensive care unit (NICU) in the observation group were significantly higher than those in the control group (all P<0.05). Conclusions:Application of AI technology to nutritional management of gestational diabetes can better control the maternal perinatal weight gain and blood glucose level, reduce the incidence of anemia in the third trimester of pregnancy, the incidence of macrosomia, the use of insulin and the rate of conversion to cesarean section, and improve the neonatal outcome.
