Application of CEEMD noise reduction algorithm in ultrasound imaging in evaluating fetuses with abnormal glucose metabolism in late pregnancy

SUMMARY

Objectives: To explore the predictive effect of abnormal glucose metabolism and fetal hemodynamic parameters on adverse pregnancy outcome.Methods: One hundred and nine pregnant women with abnormal glucose metabolism during pregnancy from June 2016 to October 2018 were selected and divided into poor prognosis group (34 cases) and good prognosis group (75 cases). The hemodynamic parameters of fetal cerebral artery (MCA), umbilical artery (UA) and uterine artery of pregnancy (UT-A), including peak systolic velocity (s / D), resistance index (RI) and plasticity index (PI), were measured by color Doppler ultrasound. The receiver operating characteristic (ROC) curve of adverse pregnancy outcomes was drawn and the best threshold index was determined.Results: MCA-PI poor prognosis group, MCA-RI, RI ratio (MCA/UA) are lower than the good prognosis group, Ut-A-PI is higher than the good prognosis group (P<0.05,). ROC curve analysis results show that when the MCA-PI 1.56, the sensitivity of the predicted adverse outcomes of pregnancy, the highest specificity<, was 91.18%, 80.00%, respectively. Logistic regression analysis of risk factors shows poor pregnancy outcomes include: pregnant women, older age, body mass index =24.0kg/m2 and a family history of diabetes. Protective factors include exercise during pregnancy, MCA-PI=1.56, MCA-RI=0.63 and RI The ratio (MCA/UA) =0.84.Conclusion: Color Doppler ultrasound measured MCA-PI<1.56 the most important indicators of poor pregnancy outcomes as abnormal glucose metabolism during pregnancy and predict the exact cutoff. Pregnant women, older age, body mass index =24.0kg/m2 and a family history of diabetes and abnormal glucose metabolism during pregnancy risk factors for adverse outcomes of pregnancy.doi: https://doi.org/10.12669/pjms.37.6-WIT.4844How to cite this:Huang J, Wang C, Li X, Jing Y.

Diagnóstico y prevención de enfermedades genéticas. Análisis de seis años del municipio Sandino / Diagnostic and prevention of the genetic diseases. Analysis of six years of the municipality SandinoDiagnóstico y prevención de enfermedades genéticas. Análisis de seis años del municipio Sandino / Diagnostic and prevention of the genetic diseases. Analysis of six years of the municipality SandinoIntroducción: En los últimos años ha aumentado la importancia de las anomalías congénitas y enfermedades hereditarias como causa de muerte en el primer año de vida. El Programa de Diagnóstico y Prevención de Enfermedades Genéticas ha contribuido a la reducción de las tasas de mortalidad infantil, los indicadores de morbilidad mejorar la calidad de vida en la comunidad. Objetivos: Realizar el análisis del comportamiento del Programa de genética médica en el municipio Sandino durante seis años de funcionamiento. Método: Se realizó un estudio descriptivo, prospectivo, de corte longitudinal del total de gestantes desde el 1 de enero de 2000 hasta el 31 de diciembre de 2005, en las dos Áreas de Salud del municipio utilizando datos de la consulta municipal y provincial de Genética. Resultados: 2388 gestantes asistieron a Consulta Genética Comunitaria. 725 de ellas (30.4%) se clasificaron con riesgo incrementado. Los principales fueron la edad materna avanzada, embarazo en la adolescencia y los antecedentes familiares. El 9.84% de las Alfafetoproteínas resultaron elevadas, 48.9 % sin causa explicable. 11 pacientes decidieron no realizarse el diagnóstico prenatal citogenético y de los realizados 1 fue positivo. Los 31 casos de malformaciones detectadas decidieron interrumpir el embarazo. Conclusiones: El acercamiento de los Servicios de Genética Médica a la población y el desarrollo de la Genética Comunitaria facilitan la detección de riesgos si los casos son remitidos a tiempo al servicio de Genética. El embarazo en edades extremas conlleva los principales riesgos genéticos presentes en las gestantes estudiadas. Por cada fallecido se realizaron 6,2 interrupciones de embarazos por malformaciones. Palabras clave: Mortalidad infantil. anomalía congénita, enfermedad hereditaria, diagnóstico prenatal.ABSTRACT Introduction: In the last years Congenital Anomalies and hereditary diseases have gained importance, as a cause of death during the first year of life. The program for the ¨Diagnosis and Prevention of Genetic Diseases¨ has contributed to the reduction of infant mortality rates, and the morbility indicators, and to improve the quality of life within the community. Objective: To analyze how well the Genetic Program has been functioning in Sandino during the last six years. Method: It was held to descriptive, prospective study of longitudinal out with 100% of all pregnant women from January 1st, 2000 up to December 31st, 2005, in two health areas of the municipality, using data found in both the municipal and the provincial community Genetics Medical Assistance. Results: 2,388 pregnant women were attended in the community's Genetics Assistance, out of them just 725 (30, 4) were detected with increased risk. The main causes were advanced maternal age, teenage pregnancy and family records. Around 9.84% Alpha-fetoproteins reached high levels, 48.9% without a reasonable cause. Eleven patients decided not to go though the cytogenetic prenatal diagnosis and one resulted positive out of those carried out. The 31 cases of malformations detected decided to interrupt their pregnancy. Conclusion: The approach of the Genetic Service in the population y the Community's Genetics assistance contribute to the detection of risks as long as they go to visit the Genetic Physician on time. Pregnancy in deadline age constitutes the main genetic risk present in the pregnant women studied. For each person deceased about 6.2 abortions of pregnancy were done because of malformations. Key words: Infant mortality, genetic abnormalities, genetic diseases, prenatal diagnosis.
