Capacidad del diámetro biparietal para predecir los recién nacidos grandes para edad gestacional. Estudio de cohorte retrospectivo / Ability of biparietal diameter to predict large for gestational age newborns. A retrospective cohort study

Fundamento: Predecir el recién nacido grande para la edad gestacional es una acción de salud que necesita de herramientas tecnológicas de probada eficiencia. Objetivo: Determinar la capacidad predictiva del diámetro biparietal en los recién nacidos grandes para la edad gestacional. Metodología: Estudio de cohorte retrospectivo que incluyó 1959 gestantes cubanas con embarazo simple con captación y término del embarazo entre enero del 2009 y diciembre de 2017. En cada trimestre de gestación se compararon las condiciones tróficas adecuado para la edad gestacional (AEG) y grandes para la edad gestacional (GEG) mediante estadígrafos de tendencia central (media) y de dispersión (rango, desviación estándar) correspondientes al diámetro biparietal. Se calculó además el intervalo de confianza (IC) de 95 % para la diferencia de medias del diámetro biparietal. Asimismo, se realizó un análisis de curvas ROC para determinar si el diámetro biparietal y el peso fetal predicen la condición trófica grande para la edad gestacional en el segundo y tercer trimestre de gestación. Los datos fueron recogidos del libro registro de genética del área de salud. Resultados: El diámetro biparietal en el segundo y tercer trimestre de gestación tuvo un área bajo curva de 0.60 (IC 95 %: 0.54-0.65) y 0.59 (IC 95 %: 0.54-0.64) respectivamente. Los puntos de corte establecidos (T2: 56.55 mm, T3: 81.55 mm) tienen una especificidad y exactitud superior al 78 %. Conclusiones: El diámetro biparietal y los modelos de regresión de Shepard y de Hadlock V mostraron capacidad para discriminar el nacimiento grande para la edad gestacional del adecuado para la edad gestacional, a partir del segundo trimestre de gestación siendo más eficaces en el tercero.

Background: Predicting large for gestational age newborns is a medical action that requires technological tools with proven efficiency. Objective: To determine the predictive ability of biparietal diameter in large newborns for gestational age. Methodology: Retrospective cohort study that included 1959 Cuban pregnant women with a singleton pregnancy, with recruitment and pregnancy term between January 2009 and December 2017. In each gestational trimester, trophic conditions appropriate for gestational age (GAW) were compared and large for gestational age (GA) using central tendency (mean) and dispersion (range, standard deviation) statistics corresponding to the biparietal diameter. The 95% confidence interval (CI) for mean biparietal diameter difference was also calculated. In addition, an analysis of ROC curves was performed to determine if biparietal diameter and fetal weight predict large trophic condition for gestational age in the second and third gestational trimester. Data were gathered from the health area genetics registry book. Results: Biparietal diameter in the second and third trimester of gestation had an area under curve of 0.60 (95% CI: 0.54-0.65) and 0.59 (95% CI: 0.54-0.64) respectively. The established cut-off points (T2: 56.55 mm, T3: 81.55 mm) have a specificity and accuracy greater than 78%. Conclusions: Biparietal diameter and the Shepard and Hadlock V regression models showed ability to discriminate large for gestational age birth from adequate for gestational age birth from the second trimester of gestation onward, being more effective in the third trimester.

Abdomen agudo por torsión de masa anexial en tercer trimestre del embarazo, reporte de un caso y revisión de la literatura / Adnexal mass torsion as a cause of acute abdomen in the third trimester of pregnancy. Case report and review of the literature

Resumen INTRODUCCIÓN: Las masas anexiales en el embarazo son hallazgos fortuitos durante la gestación. Suelen diagnosticarse con la ecografía del primer trimestre. Su incidencia y curso clínico varían dependiendo de las semanas de embarazo. La complicación más común es la torsión con abdomen agudo. La incidencia de torsión va de 0.2 a 15%, con aumento durante el embarazo con masas de mayor tamaño. Son poco frecuentes durante el tercer trimestre del embarazo. Los cistoadenomas mucinosos son parte de los tumores epiteliales benignos más frecuentes del ovario; se consideran precursores de carcinomas mucinosos. CASO CLÍNICO: Paciente de 34 años, con antecedentes obstétricos de cuatro embarazos: dos partos y dos abortos, con 31 semanas de embarazo al ingreso al Hospital Universitario de la Samaritana de Colombia, justificado por un cuadro clínico de 18 horas de evolución consistente en: dolor abdominal intenso, tipo punzada, de predominio en la fosa iliaca y el flanco derechos. En la laparotomía se encontró un tumor ovárico con torsión, que se resecó. El estudio anatomopatológico reportó "tumor mucinoso de tipo endocervical con severos cambios por infarto". La evolución materno perinatal fue satisfactoria. CONCLUSIONES: El diagnóstico de torsión de masa anexial como causa de abdomen agudo en el tercer trimestre del embarazo es complejo pues requiere historia clínica, imágenes y estudios paraclínicos. El pronóstico materno-perinatal es bueno cuándo el tratamiento médico-quirúrgico es oportuno. Se requiere determinar el tipo de masa con estudios anatomopatológicos para continuar el tratamiento integral. El tumor mucinoso de ovario, tipo endocervical en masas torcidas de ovario, es raro.

Abstract BACKGROUND: Adnexal masses of pregnancy are incidental findings during pregnancy. They are usually diagnosed with first trimester ultrasound. Their incidence and clinical course vary depending on the weeks of pregnancy. The most common complication is torsion with acute abdomen. The incidence of torsion ranges from 0.2 to 15%, with an increase during pregnancy with larger masses. They are rare during the third trimester of pregnancy. Mucinous cystoadenomas are among the most frequent benign epithelial tumors of the ovary; they are considered precursors of mucinous carcinomas. CLINICAL CASE: 34-year-old female patient, with obstetric history of four pregnancies: two deliveries and two miscarriages, 31 weeks pregnant on admission to the Hospital Universitario de la Samaritana of Colombia, justified by a clinical picture of 18 hours of evolution consisting of: intense abdominal pain, stabbing type, predominantly in the right iliac fossa and flank. At laparotomy the torsion was found and resected. The anatomopathological study reported "mucinous tumor of endocervical type with severe infarction changes". Maternal perinatal evolution was satisfactory. CONCLUSIONS: The diagnosis of adnexal mass torsion as a cause of acute abdomen in the third trimester of pregnancy is complex as it requires clinical history, imaging and paraclinical studies. The maternal-perinatal prognosis is good when medical-surgical treatment is timely. It is necessary to determine the type of mass with anatomopathological studies to continue the integral treatment. Mucinous ovarian tumor, endocervical type in twisted ovarian masses, is rare.

Correlation analysis of lipid metabolism disorder of third trimester and retinopathy of prematurity in premature infants / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To investigate the correlation between lipid metabolism disorder and retinopathy of prematurity(ROP)of premature infants. <p>METHODS: A retrospective analysis was performed on the medical data of 48 premature infants mothers who were hospitalized and diagnosed with ROP in the Department of Neonatology, Children's Hospital of Soochow University from January 2017 to December 2018. Forty-eight hospitalized no-rop premature infants mothers were enrolled as the control group during the same period. The two groups were compared in terms of blood lipids and adiponectin level in the third trimester. Pearson correlation and Logistic regression analysis were used to analyze the correlation between adiponectin and blood lipids and risk factors of retinopathy in premature infants. <p>RESULTS: The total cholesterol, triglyceride, low-density lipoprotein and apolipoprotein B level in the observation group were all higher than those in the control group, while high-density lipoprotein, adiponectin and apolipoprotein A1 level were lower than those in the control group. In addition, Pearson correlation analysis showed correlation between adiponectin and blood lipid levels, while Logistic regression analysis showed increased of total cholesterol, triglycerides, low-density lipoprotein, and apolipoprotein B and decreased of high-density lipoprotein, and apolipoprotein A1 were risk factors for ROP.<p>CONCLUSION: Pearson test indicated positive correlation between lipid disorders of third trimester and retinopathy of premature infants, which may be related to adiponectin. In clinical work, we should focus on strengthening the guidance of maternal nutrition to reduce the incidence of ROP.

Hemoglobina glucosilada en el diagnóstico de diabetes gestacional en mujeres mexicanas durante el tercer trimestre / Glycosylated hemoglobin in the diagnosis of gestational diabetes in Mexican women during the third trimester

Resumen El objetivo del trabajo fue analizar los valores de hemoglobina glucosilada en el tercer trimestre de embarazo como predictores alternativos de la diabetes gestacional en pacientes del Noreste de México. Se trata de un estudio retrospectivo de casos y controles a partir de 121 expedientes de pacientes embarazadas, divididos en dos grupos, pacientes con diabetes gestacional (casos) y gestantes con valores glucémicos normales (controles). Se analizaron los factores de riesgo asociados a la diabetes gestacional y se obtuvo un punto de corte para la hemoglobina glucosilada. Se encontró que la obesidad materna, la edad y el antecedente del padecimiento fueron asociados significativamente con la diabetes gestacional. Valores de hemoglobina glucosilada ≥5% incrementaron el riesgo de padecer diabetes mellitus gestacional 4 veces y, aunado a un factor de riesgo, la probabilidad se incrementó 7 veces. Se concluye que los valores de hemoglobina glucosilada en el tercer trimestre de embarazo podrían emplearse como prueba diagnóstica de la diabetes gestacional en pacientes del Noreste de México. Sin embargo, aunque las diferencias encontradas fueron estadísticamente significativas, los resultados se deben interpretar con cautela y requieren su confirmación con estudios que incluyan una muestra mayor.

Abstract The objective of this study was to analise glycosylated hemoglobin values in the third trimester of pregnancy as an alternative predictor of gestational diabetes in North East Mexican cohort patients. This is a retrospective case-control study based on 121 records of pregnant patients, divided into two groups, patients with gestational diabetes (cases) and pregnant women with normal glycemic values (control). The risk factors associated with gestational diabetes were analised and a cut-off point for glycosylated hemogestaglobin was obtained. It was found that maternal obesity, age and a history of the condition were significantly associated with gestational diabetes. Values of glycosylated hemoglobin ≥5% increased the risk of suffering from gestational diabetes 4 times, and coupled with a risk factor, the risk increased 7 times. It is concluded that glycosylated hemoglobin values in the third trimester of pregnancy could be used as a diagnostic test for gestational diabetes in patients from the North East of Mexico. Although the differences found were statistically significant, our results must be interpreted with caution and require confirmation by studies with a larger sample.

Resumo O objetivo deste estudo foi analisar os valores da hemoglobina glicada no terceiro trimestre de gestação como preditores alternativos do diabetes gestacional em pacientes na região nordeste do México. Trata-se de um estudo retrospectivo de casos e controles utilizando 121 prontuários de gestantes divididas em dois grupos; pacientes com diabetes gestacional (casos) e gestantes com valores de glicemia normais (controles). Foram analisados os fatores de risco associados a diabetes gestacional obtendo-se um ponto de corte para a hemoglobina glicada. Descobriu-se que a obesidade materna, idade e antecedentes da doença foram associados significativamente ao diabetes gestacional. Valores da hemoglobina glicada ≥ 5% aumentaram o risco de padecer diabetes mellitus gestacional 4 vezes, e juntamente a um fator de risco, a probabilidade aumentou 7 vezes. Conclui-se que os valores da hemoglobina glicada no terceiro trimestre de gestação poderiam ser usados como teste diagnóstico do diabetes gestacional em pacientes da região nordeste do México. Embora as diferenças encontradas tenham sido estatisticamente significativas, os resultados devem ser interpretados com cautela e requerem confirmação através de estudos que incluam uma amostra maior.

Third trimester HbA1c and the association with large-for-gestational-age neonates in women with gestational diabetes

ABSTRACT Objective: To evaluate the association between HbA1c levels measured in the third trimester and the risk for large for gestational age (LGA) in neonates of mothers affected by gestational diabetes mellitus (GDM). Secondarily, we aimed to identify an ideal cut-off for increased risk of LGA amongst pregnant women with GDM. Materials and methods: Observational retrospective review of singleton pregnant women with GDM evaluated in a diabetes and pregnancy clinic of a tertiary and academic hospital. From January/2011 to December/2017, 1,085 pregnant women underwent evaluation due to GDM, of which 665 had an HbA1c test in the third trimester. A logistic regression model was performed to evaluate predictors of LGA. A receiver-operating-characteristic (ROC) curve was used to evaluate the predictive ability of third trimester HbA1c for LGA identification. Results: A total of 1,085 singleton pregnant women were evaluated during the study period, with a mean age of 32.9 ± 5.3 years. In the multivariate analysis, OGTT at 0 minutes (OR: 1.040; CI 95% 1.006-1.076, p = 0.022) and third trimester HbA1c (OR: 4.680; CI 95% 1.210-18.107, p = 0.025) were associated with LGA newborns. Using a ROC curve to evaluate the predictive ability of third trimester HbA1c for LGA identification, the optimal HbA1c cut-off point was 5.4% where the sensitivity was 77.4% and the specificity was 71.7% (AUC 0.782; p < 0.001). Conclusions: Few studies in the Mediterranean population have evaluated the role of HbA1c in predicting neonatal complications in women with GDM. A third trimester HbA1c > 5.4% was found to have good sensitivity and specificity for identifying the risk of LGA.

Abstract OBJECTIVE: To describe the care, treatment, perinatal outcomes and complications associated with intrahepatic cholestasis of pregnancy. MATERIALS AND METHODS: A retrospective and observational case series study of pregnant patients with a diagnosis of intrahepatic cholestasis seen at the National Institute of Perinatology between January 2016 and December 2020. Obstetric characteristics, demographic, clinical, biochemical and treatment data, pregnancy termination and perinatal outcomes were evaluated. RESULTS: Sixty-seven cases of intrahepatic cholestasis were analyzed, yielding an incidence of 0.57%. The mean age of the patients was 29.0 ± 6.8 years, 30 of 67 were primigravidases, 12 had a history of intrahepatic cholestasis in the previous pregnancy and 7 had an abortion. The onset of the disease was in the third trimester in 41 of 67 patients. In biochemistry studies 32 of 67 had bile acid values between 10 and 39 μM/L; 12 of 67: 40-99 μM/L and 23 more than 100 (μM/L). Treatment with ursodeoxycholic acid was administered to 63 of 67 and rifampicin to 4 patients. The mean number of weeks of gestation was 35.6 ± 2.0 weeks with a mean weight of 2397 ± 572 g. Amniotic fluid with meconium was found in 10 neonates and growth restriction in 20 of 67; there were 2 recorded abortions. CONCLUSIONS: This is the first study carried out in Mexico in which the incidence of the disease is described, and the determination of bile acids is used to establish the diagnosis. Perinatal outcomes coincide with those reported in the literature.

Relationship of plasma vitamin A levels between neonates and pregnant women in third trimester / 北京大学学报(医学版)

OBJECTIVE@#To study the correlation of plasma vitamin A (VitA) levels between neonates and pregnant women in third trimester.@*METHODS@#A total of 688 pregnant women were recruited in Yuanshi and Laoting counties of Hebei Province, from May to June 2009. Venous blood samples of women before delivery and cord blood samples of newborns were collected and measured for retinol (retinol concentration was used to reflect VitA level) using high performance liquid chromatography assay. According to venous blood plasma retinol concentration, maternal VitA nutritional status was divided into deficiency (<0.70 μmol/L), marginal deficiency (0.70-<1.05 μmol/L), and sufficiency (≥1.05 μmol/L). According to cord blood plasma retinol concentration, neonatal VitA nutritional status was divided into deficiency (<0.35 μmol/L), marginal deficiency (0.35-<0.70 μmol/L), and sufficiency (≥0.70 μmol/L); neonatal VitA relative deficiency was further defined as cord blood plasma retinol concentration lower than the 10th percentile. VitA placental transport ratio was defined as retinol concentration in the neonates divided by that in pregnant women. Multivariable fractional polynomials (MFP) model and Pearson correlation were used to study the dose-response relationship between maternal and neonatal plasma VitA levels, Logistic regression model to estimate the effect of maternal VitA nutritional status on neonatal VitA deficiency, and MFP model and Spearman correlation to describe the relationship between maternal VitA level and VitA placental transport ratio.@*RESULTS@#The average retinol concentration of the pregnant women was (1.15±0.30) μmol/L, and the prevalence of VitA deficiency and marginal deficiency were 4.5% and 37.8%, respectively. Average retinol concentration of the neonates was (0.78±0.13) μmol/L, and no neonates were VitA deficiency, 28.2% of the neonates were marginal deficiency. After multivariable adjustment, the VitA level of the neonates was positively and linearly related to maternal VitA level (pm=1, P<0.05), with the corresponding Pearson correlation coefficient of 0.13 (P<0.01). As compared with the women with sufficient VitA, those with VitA deficiency (crude OR=2.20, 95%CI:1.04-4.66) and marginal deficiency (crude OR=1.43, 95%CI:1.01-2.02) had higher risks to deliver neonates with VitA marginal deficiency; while the risks turned to be non-significant after multivariable adjustment. The pregnant women with VitA deficiency had higher risk to deliver neonates with relative VitA deficiency before and after multivariable adjustment (crude OR=3.02, 95%CI:1.21-7.50; adjusted OR=2.76, 95%CI:1.05-7.22). The maternal VitA level was negatively and non-linearly correlated with placental transport ratio (pm= -0.5, P<0.05), with corresponding adjusted Spearman correlation coefficient of -0.82 (P<0.001).@*CONCLUSION@#There was a positive linear dose-response relationship between VitA levels of newborns and pregnant women in third trimester, indicating that neonatal VitA storing levels at birth was affected by maternal VitA nutritional status.

Changes in blood and urine parameters among pregnant women during third trimester

Background: During pregnancy, the pregnant lady undergoes significant anatomical and physiological changes in order to nurture and accommodate the developing fetus. These changes begin after conception and affect every organ system in the body.Methods: The study was carried out in the United Arab Emirates - Ajman (Thumbay Hospital) during the period of (March - Jun) in the year of 2018 to estimate HbA1c% levels, hematological blood parameters and urine culture in healthy pregnant women during 3rd trimester. The study was conducted on (108) healthy pregnant women during3rd trimester. Urine culture was performed to detect the growth of bacteria after the culture, gram stain was done to differentiate the bacteria followed by biochemical test to detect the type of bacteria.Results: A total 26 (79%) of patients had normal HbA1c% result while 7(21%) had elevated HbA1c% result. The results of HbA1c% in last trimester mean±SD (range) HbA1c% (n=33) were 5.5±0.52% (111.5±14.8 mg/dL). Also, our results showed strong positive correlation between HbA1% with estimated Average blood glucose (r=0.78, P value=0.00), and weak positive correlation between HbA1 with age (years) (r=0.2, P value=0.02). Bacterial culture showed that two positive results of stenotrophomonas maltophilia was isolated, three cases of Staphylococcus aureus was isolated and three cases of staphylococcus saprophyticus. Hematological profile showed a clinically significant (≤ 0.05) in Hb mean 11.47, P value 0.001, HCT mean, 33.9 P value 0.001 and MCV mean 73.7 value 0.001. No clinically significant (≥ 0.05) in RBCs mean 3.93, P value 0.010, MCH mean 27.3 P value 0.061 and MCHC mean 30.9 P value 0.134.Conclusions: Our study conclude that estimation of HbA1c%, hematological blood parameters and urine culture level in last trimester will be helpful in diagnosis, monitoring and predicting fetal distress.

Fetal transverse cerebellar diameter measurement in intrauterine growth restriction: a more accurate parameter for gestational age assessment at term

Background: Assessment of fetal gestational age (GA) is an essential part of obstetric USG. Accurate knowledge of fetal GA is important to facilitate the best possible prenatal care and successful pregnancy outcome.  For the estimation of GA the commonly used parameters in third trimester are:- BPD, HC, AC and FL. As all these parameters are affected by fetal growth disorders and fetal position. TCD can be used as another parameter for the estimation of GA in growth restricted fetuses.Methods: This study was conducted at Mahila Chikitsalaya Sanganeri Gate; SMS Medical College Jaipur from July 2005 to September 2006. A total of 80 pregnant women in third trimester with singleton pregnancy including 40 pregnant women with known cases of IUGR and 40 AGA fetuses were studied for TCD measure.Results: Correlation coefficient between TCD and gestational age was highly significant and no significant difference was found in TCD of AGA and IUGR fetuses.Conclusions: TCD measurement can be used as more reliable parameter for accurate estimation of gestational age in IUGR fetuses in third trimester.

Role of IV administered Iron sucrose with recombinant erythropoietin in the treatment of moderate and severe iron deficiency anemia in the third trimester of pregnancy

Background: Iron deficiency Anemia in pregnancy is one of the most common and intractable nutritional problems in the world today. The objective of this study was to investigate the therapeutic efficacy and safety of rHuEPO combined with IV iron sucrose, in the treatment of pregnant women in third trimester with moderate and severe iron deficiency anemia and whether addition of erythropoietin will increase the rate of rise of Hb without compromising on the safety of the therapy.Methods: 60 pregnant women in the third trimester, diagnosed as cases of moderate and severe iron deficiency anemia were enrolled in this study with 30 subjects in each of the 2 groups. Recombinant Erythropoietin 2000 IU s/c and Inj Iron sucrose 100 mg slow intravenously in 100 ml 0.9% NS over 1 hr on alternate days was administered to the case group and the control group was administered only iron sucrose slow IV in the same dose on alternate days till target Hb (11gm%) was reached. Efficacy measures were reticulocyte count, increase in Hb/week, time to target Hb level and need for continued therapy after 4 weeks.Results: In the case group, the increases in Hb were greater after 1 week of treatment and this was found to be significant (P < .01), the median duration of therapy was shorter in the case group (22 versus 34 days), with more patients reaching the target hemoglobin level by 4 weeks as opposed to 7 weeks in the control group. Average rise in Hb/week was much more in the case group. The groups did not differ with respect to maternal and fetal safety parameters.Conclusions: Iron sucrose plus rhEPO is an effective treatment for iron deficiency anemia in pregnancy probably because of a synergistic action, with rhEPO stimulating erythropoiesis and iron sucrose delivering iron for hemoglobin synthesis.

Evaluation Of Postural Balance In Third Trimester Pregnancy

Background: Pregnancy is a state of various physiological and anatomical changes in a female’s body. The increasing body weight leads to the shift in COG and increase in abdominal contents leading to reduced stability and increased use of visual cues which occur in pregnant females as pregnancy advances. Several physiological responses to pregnancy diminish the body’s ability to maintain adequate balance, and place the women at a higher risk of injury and falls. Thus assessment for postural stability is very important to prevent such complications. Objective: To evaluate postural balance in third trimester pregnant females using Four square step test. Materials and methodology: Study was cross sectional observational study. Data was collected by convenient sampling method .60 Healthy women, 30 pregnant and 30 non-pregnant, of age group 20-30 years were selected. Evaluation of postural stability was done using 4 square step test (FSST). The mean of two time trial (in seconds) was noted. The data was collected and analysed using paired t-test. Results: There was statistically significant difference in mean time taken to complete the test between pregnant group and non-pregnant group. (p<0.05) Conclusion: Thus, our study showed that pregnant females took longer time to complete the postural balance test.

Hematological changes in cord blood of anemic and hypertensive pregnant women

Background: Infant and maternal mortality has raised serious concerns since ages. Ongoing researches in this field aim to develop insights into successful maternal and infant health-care programs. Objective: A comparative study of hematological changes in cord blood in anemic and hypertensive pregnant women with normal pregnant women. Materials and Methods: This study was undertaken in the Department of Physiology in collaboration with the Department of Pathology and Department of Obstetrics and Gynaecology of Government Medical College, Kannauj, after taking permission from the Institutional Ethics Committee. Sample size included 150 third trimester pregnant women of 20–40 years. Group I (normal) included subjects (n = 50) with hemoglobin (Hb) concentration more than 11 gm/dl and blood pressure (systolic range = 100–139 mmHg; diastolic range = 60–89 mmHg). Group II (anemic) included subjects (n = 50) with Hb concentration <11 gm/dl and blood pressure (systolic range = 100–139 mmHg; diastolic range = 60–89 mmHg). Group III (hypertensive) included Hb concentration of more than 11 gm/dl and blood pressure ≥140/90 mmHg. Hematological parameters (Hb concentration, total red blood cell (RBC) count, blood indices, total platelets count, total white blood cells count, and differential leukocyte count in maternal blood and cord blood) were duly studied. Results: Hb concentration, RBC count, mean cell volume of red blood, mean corpuscular Hb (MCH), and MCH concentration were observed significantly lower in anemic mothers, but there were no statistically significant differences noted between mother’s and her cord blood investigations. Absolute neutrophil count (1000/mm3), absolute lymphocyte count (1000/mm3), and platelets count (lacs/mm3) were significantly decreased in cord blood of hypertensive mothers (Group III). Conclusion: Conditions such as anemia and hypertension in pregnancy influence hematological changes in cord blood which, in turn, adversely affect the perinatal outcome.

¿Qué hay en común entre el hígado graso agudo del embarazo y la preeclampsia? Subdiagnóstico clínico de alta mortalidad / What is in Common Between Acute Fatty Liver of Pregnancy and Preeclampsia? Highly Mortal Clinical Sub-Diagnosis / O que tem em comum o fígado gorduroso agudo da gestação e a pré-eclâmpsia? Subdiagnóstico clínico de alta mortalidade

Resumen: El hígado graso agudo del embarazo es una de las alteraciones hepáticas con mayor mortalidad (cerca del 18%) presentes en la gestación, aunque es una patología poco frecuente: 1 de cada 7000 a 16.000 embarazos presenta muchas complicaciones y requiere un manejo inmediato para evitar la muerte de la gestante o del feto; sin embargo esta patología se puede enmascarar con la preeclampsia, que es otra patología hepática de mayor frecuencia, lo cual retrasa el manejo y aumenta el número de complicaciones. El objetivo de este artículo es realizar una búsqueda bibliográfica acerca del hígado graso agudo del embarazo e identificar los factores similares entre esta patología y la preeclampsia severa para lograr hacer un diagnóstico y manejo oportunos. Para ello se realizó una búsqueda sistemática en las bases de datos, PubMed, Science Direct, Medline, Embase, en junio de 2017; además, se seleccionaron artículos originales, reportes de casos y artículos de revisión, publicados en los últimos diez años.

Abstract: Acute fatty liver of pregnancy (AFLP) is one of the liver disorders with the highest mortality rate (about 18%) during pregnancy, although it is rare: 1 in 7,000 to 16,000 pregnancies has many complications and requires immediate treatment to avoid the death of the pregnant woman or the fetus. However, this pathology can be masked by preeclampsia, which is another more frequent liver disease. This delays treatment and increases the number of complications. The aim of this article is to conduct a bibliographic search about AFLP and identify similar factors between this pathology and severe preeclampsia to make a diagnosis and provide treatment in a timely manner. For this, a systematic search was carried out in databases (PubMed, Science Direct, Medline, Embase) in June 2017. In addition, original articles, case reports, and review articles published in the last ten years were selected.

Resumo: O fígado gorduroso agudo da gestação é uma das alterações hepáticas com mais mortalidade (cerca de 18 %) presentes na gravidez, embora seja uma patologia pouco frequente: 1 de cada 7.000 a 16.000 gestações apresenta muitas complicações e requer uma ação imediata para evitar a morte da gestante ou do feto. Contudo, essa patologia pode ser camuflada com a pré-eclâmpsia, que é outra patologia hepática de maior frequência, o que atrasa seu tratamento e aumenta o número de complicações. Nesse sentido, o objetivo deste estudo é realizar uma busca bibliográfica sobre o fígado gorduroso agudo da gestação e identificar os fatores semelhantes entre ele e a pré-eclâmpsia grave para poder fazer um diagnóstico e tratamento oportunos. Para isso, foi realizada uma busca sistemática nas bases de dados, PubMed, Science Direct, Medline, Embase, em junho de 2017, das quais foram selecionados artigos originais, relatos de caso e artigos de revisão, publicados nos últimos dez anos.

Hemorragia de la Segunda Mitad del Embarazo en el Hospital Provincial General Docente Riobamba, Chimborazo, Ecuador 2017 - 2018 / Antepartum hemorrhage in the Hospital Provincial General Docente Riobamba, Chimborazo, Ecuador 2017 - 2018

Introducción: la hemorragia obstétrica es la segunda causa más frecuente de mortalidad materna en el Ecuador, a pesar de ello, es un tema que se ha estudiado poco a nivel provincial y nacional. Objetivo: determinar la ocurrencia e identificar los factores de riesgo, manifestaciones clínicas y comorbilidades más frecuentes de la hemorragia de la segunda mital del embarazo. Métodos: estudio descriptivo, transversal, donde se analizaron las historias clínicas de las pacientes obstétricas con hemorragia de la segunda mitad del embarazo atendidas en el Hospital Provincial General Docente Riobamba (HPGDR) entre junio 2017 y junio 2018. Resultados: de un total de 3 460 pacientes obstétricas atendidas, 0.49% (n = 17) cumplieron los criterios de hemorragia en la segunda mital del embarazo, las cuales tuvieron una edad media de 29 años (desviación estándar = 7), una edad gestacional media de 36 semanas (desviación estándar = 5) y en su mayoría fueron multíparas. El desprendimiento de placenta normoinserta fue la principal patología causante de la hemorragia y el dolor abdominal el principal síntoma manifestado, en la mayoría no se observó otras comorbilidades obstétricas. Conclusión: se observó una baja ocurrencia de hemorragia de la segunda mitad del embarazo en el HGDR entre junio 2017 y junio 2018, siendo la causa más frecuente el desprendimiento de placenta normoinserta y el principal mitivo de consulta dolor abdominal.

Introduction: obstetric hemorrhage is the second most frequent cause of maternal mortality in Ecuador. Nevertheless, the topic has been little studied at a local and national level. Objective: to determine the ocurrence and identify the most frequent risk factors, clinical manifestations and comorbilities in antepartum hemorrhage. Methods: it is a descriptive, cross-sectional study, in which clinical histories of obstetric patients with hemorrhage of the second half of pregnancy were analyzed in the Hospital Provincial General Docente Riobamba (HGPDR) between June 2017 and June 2018. Results: from 3 460 obstetric patients attended, 0.49% (n = 17) met antepartum hemorrhage criteria. Women were in average 29 years old (standard deviation = 7), had an average gestational age of 36 weeks (standard deviation = 5) and were multiparous. Detachment of normoinserta placenta was the main cause of bleeding, abdominal pain was the most frequent symptom reported and in the majority of cases no obstetric comorbilities were observed. Conclusions: it was observed a low ocurrence of hemorrhage of the second half of pregnancy in the HGDR between June 2017 and June 2018. The mots common cause of the patology was detachment of normoinserta placenta and the most frequent complain reported was abdominal pain.

Effect of eclampsia on pregnancy outcome at tertiary care center, Gujarat, India

Background: Eclampsia, a common medical emergency of pregnancy mainly seen in 5% to 10% of all pregnancies. The objective of the present study was to study the effect of eclampsia on maternal and perinatal outcome.Methods: This cross-sectional study was conducted among 50 clinically diagnosed women with eclampsia in their third trimester of pregnancy. Inclusion criteria for the study was; females with singleton pregnancy, all in the third trimester which were diagnosed to have PIH based on the development of hypertension for the first time, proteinuria with or without edema, with no history of previous urinary tract troubles and no evidence of UTI.Results: Almost 84.0% participants were belonged to age group of 20 to 30 years age, 54.0% were belonged to rural area and 92.0% were belonged to lower socio-economical class, 88.0%% participants were registered as emergency case, 34.0% participants were stayed more than 10 days at hospital and 36.0% were completed ANC visit. Almost 24.0% participants were anemic, 6.0% pre-eclampsic and 4.0% have tween pregnancy. Severe hypertension at the time of admission were noted in 50.0% participants followed by absent knee jerk (12.0%), proteinuria (78.0%) and edema (62.0%) respectively. Maternal mortality and still birth observed in 2.0% and 18.0% cases respectively.Conclusions: Early age, lower socio-economic class, anemia, less ANC clinic visit, higher hospital stay and primigravida observed more among study participants and these factors may play an important role in the pathogenesis of eclampsia.

Influence of the ultrasound examination duration using supine position on umbilical artery blood flow parameters and fetal heart rate in the third?trimester pregnant women / 中国综合临床

Objective To investigate the influence of the length of time of supine ultrasound examination on the parameters of umbilical artery blood flow in the late pregnant fetus. Methods From February 2019 to June 2019,the ultrasound data of 93 pregnant women with the third-trimester pregnant were analyzed retrospectively. Fetal umbilical artery systolic／diastolic ( S／D ) ratio, resistance index ( RI ), pulsatility index ( PI ) and fetal heart rate ( HR ) were acquired at the beginning of the ultrasound examination and those after the routine ultrasound examination ( the examination of fetal, placenta and amniotic fluid). Forty-seven pregnant women from 29 to 31 weeks of gestation were assigned to around 30-week gestation group,while 46 pregnant women from 35 to 37 weeks of gestation were assigned to around 36-week gestation group. Sixty-five pregnant women with normal S／D ratio at the beginning were assigned to the initial normal group,while 28 pregnant women with abnormal S／D ratio at the beginning were assigned to the initial abnormal group. Fetal umbilical artery S／D ratio,RI,PI and HR at the beginning of the ultrasound and after the routine ultrasound examination were compared using paired sample test within around 30-week gestation group, around 36-week gestation group, initial normal and initial abnormal group, respectively. Results There was no significant difference in fetal umbilical artery S／D,RI PI and HR in the pregnant women at around 30-week gestation(all P＞0. 05). RI before the 36 week pregnant group was 0. 56 ±0. 05,and increased to 0. 58±0. 05 after the routine examination (t＝－2. 190,P＝0. 034). The S／D,RI and Pi of umbilical artery increased from 2. 36±0. 31,0. 57±0. 06,and 0. 84±0. 11 to 2. 50±0. 42,0. 59±0. 06, and 0. 88±0. 14 in the initial normal group ( t＝－3. 087,－3. 002,－2. 287,respectively; P＝0. 003,0. 004, 0. 025,respectively),of which 16 S／D increased to abnormal; the RI of umbilical artery increased from 0. 67 in the initial abnormal group ( 28 women ) after routine examination ) . The difference was statistically significant (t＝2. 616,P＝0. 014) . The ratio of S／D decreased to normal after routine examination in the initial abnormal group ( 14／28), which was higher than that in the initial normal group ( 16 ／ 65) . The difference was statistically significant ( χ2 ＝5. 771, P＜0. 05) . Conclusion Umbilical artery blood flow parameters should be measured at the beginning of the ultrasound examination in the third-trimester pregnant women. Umbilical artery Doppler ultrasound should be performed repeatedly if the pregnant woman has abnormal S／D ratio at the beginning of the examination.

Study on monitoring of Streptococcus agalactiae in third trimester women and its relationship with vaginal microenvironment / 国际检验医学杂志

Objective To investigate the value of real-time fluorescent quantitative polymerase chain reaction (RT-qPCR) in the detection of Streptococcus agalactiae in early screening of Streptococcus agalactiae in pregnant women in the third trimester, and to study the effect of Streptococcus agalactiae infection on them.Methods A retrospective analysis of 5 855pregnant women with vaginal discharge and rectal secretions from January 2017to January 2018in our hospital were performed to detect Streptococcus agalactiae by RT-qPCR.Meanwhile, 100vaginal non-vaginosis women in the third trimester were selected as the negative group and100healthy women as the control group.The vaginal micro-environment-related indexes (Lactobacilli content, flora diversity and cleanliness) of three groups were analyzed.Results The total carrier rate of Streptococcus agalactiae of the third trimester from January 2017to January 2018in our hospital was 9.6％, of which vaginal carriage rate was 2.4％, rectum carriage rate was 7.2％, Streptococcus agalactiae positive group (GradeⅡ-Ⅲ), rates of population diversity (GradeⅡ-Ⅲ) cleanliness (Ⅰdegree) and microenvironment imbalance were 30.1％, 36.4％, 25.9％and 76.2％respectively, while those in the negative group were 58.0％, 55.0％, 61.0％and 63.0％and those in the control group were 87.0％, 91.0％, 83.0％, 24.0％.The positive rate of Streptococcus agalactiae in each group was significantly higher than that in the control group (P＜0.05).The differences of all the indexes between the negative group and the control group were also statistically significant (P＜0.05).Conclusion The carrying rate of Streptococcus agalactiae in third trimester pregnancy in our hospital was within the normal range reported in the literature.The detection of Streptococcus agalactiae by RT-qPCR could be effectively screened and monitored.Carrying Streptococcus agalactiae might increase the risk of vaginal infection in third trimester women.

The follow-up observation on the abnormal elevation of fetal pulmonary artery systolic pressure at middle and late stages by Doppler echocardiography / 中华超声影像学杂志

Objective To investigate the outcome of fetus with abnormal increase of pulmonary artery systolic pressure at second and third trimester by color Doppler ultrasound . Methods Ninety-five fetuses with a little or mild tricuspid regurgitation ( control group) and 60 fetuses with moderate and severe tricuspid regurgitation (observation group) were included . The degree ,velocity ,and differential pressure of tricuspid regurgitation were measured and the variations of baseline information and the measured value of pulmonary systolic pressure between the two groups were compared . As for the follow -up on observation group ,the pressure of fetus with high pulmonary systolic pressure ( > 20 mmHg) was repeatedly measured every 4 weeks until it return to normal . Results There were significant differences in terms of gestational weeks ,velocity and pressure of tricuspid regurgitation ,as well as pulmonary systolic pressure between the two groups ( P < 0 .001) . Pulmonary systolic pressure was positively correlated with gestational weeks , velocity and pressure of tricuspid regurgitation ( r = 0 .442 ,0 .998 ,0 .999 ;all P < 0 .001 ) ,but had no correlations with the age of pregnant women ( r = - 0 .001 , P = 0 .674) . The follow-up revealed that ,in observation group , 47 cases ( 78 .3％ , systolic pressure < 50 mmHg ) presented with the decreased pulmonary systolic pressure ,the disappeared or the slight appeared regurgitation before birth ,meanwhile , 13 ( 21 .7％ ,systolic pressure ≥ 50 mmHg) exhibited severe tricuspid regurgitation and persistent pulmonary elevation ,with the highest of more than 70 mmHg accompanying the varying degrees of right heart failure . Only one of 13 fetuses died due to persistent pulmonary hypertension and hypoxia ( oxygen saturation <45％ ) . The fetal pulmonary artery systolic pressure of the remaining 12 cases recovered from 5 to 105 days after birth ,with normal heart function . Conclusions The majority of fetal pulmonary arterial hypertension complicated with obvious tricuspid regurgitation is reversible functional alteration , which can restore normality in most cases before or after birth .

Clinical treatment of acute aortic dissection in late pregnancy and puerperium / 中国胸心血管外科临床杂志

@#Objective    To study the clinical characteristics, therapy strategies and the outcomes of female patients with acute aortic dissection during late pregnancy and puerperal period. Methods    We retrospectively analyzed the clinical data of 7 patients with acute aortic dissection during late pregnancy and puerperal period in Shanghai Changhai Hospital between August 2012 and June 2017. Five of the 7 patients were late stage pregnancy, 2 were puerperal period (1 at the postpartum night, 1 in 18 days after delivery). There were 6 patients of Stanford type A aortic dissection (85.7%), and 1 patient of type B aortic dissection (14.3%). The age of the patients ranged from 26 to 34 (30.8±3.1) years. Cardiac ultrasonography of patients with type A showed that the maximum diameter of the ascending aortas was 4.2–5.7 (4.7±0.6) cm, of which 2 patients were aneurysm of aortic sinus, 3 patients were with Marfan syndrome. Bentall procedure was conducted in 1 patient, Bentall+Sun’s surgery in 2 patients, ascending aorta replacement+Sun’s+coronary artery bypass grafting surgery in 1 patient, aortic root remodeling+ascending aorta replacement+Sun’s surgery in 2 patients. One patient with Stanford type B acute aortic dissection was performed with thoracic endovascular aortic repair (TEVAR) after cesarean section. Results     Aortic blocking time ranged from 51 to 129 (85.5±22.9) min.  Cardiopulmonary bypass time was 75–196 (159.0±44.0) min. Moderate hypothermic circulation arrest with selective cerebral perfusion time was 20–30 (23.8±3.5) min. All maternal and fetuses survived. The infant whose mother received aortic repair in early stage and then received cesarean section was diagnosed with cerebral palsy. Maternal and fetuses were followed up for 9 months to 4 years. During the follow up period, all the fetuses grew well except the cerebral palsy one, and all maternal recovered well. The patient who received aortic repair in the early stage, had a sigmoid rupture during cesarean section and was treated with sigmoid colostomy. Another patient with Stanford type A dissection was diagnosed as left renal vein entrapment syndrome after 2 years. Conclusion    Type A aortic dissection is more common in late pregnancy and puerperal patients. And Marfan syndrome is a high-risk factor for acute aortic dissection in pregnancy women. Early and appropriate surgical treatment strategy based on the type of aortic dissection and gestational age are the key points to achieve good outcomes both for maternal and fetus.

Analysis of Perinatal Outcomes and Pregnancy Complications at the Third Trimester in Excessive Fast Weight Gain Pregnant Women Who Had Normal 75g OGTT at the Second Trimester / 实用妇产科杂志

Objective:To analysis perinatal outcome and pregnancy complications in the third trimester in excessive fast weight gain pregnant women who had normal 75 g oral glucose tolerance test(OGTT) at the second trimester.Methods:422 pregnant women who examined and delivered in Department of Obstetrics,the Second Hospital of Tianjin Medical University from October 2015 to September 2016 were selected randomly for this study.All of them had normal pre-pregnancy body mass index (BMI) and 75 g OGTT test at 24-27 +6 gestational weeks.Mass growth more than 4000 g from 28-36 gestational weeks (average mass growth rate ≥500 g/w) were enrolled in study group(n =103),while others were included in control group(n =319).Statistical analysis was performed by t test and x 2 test.Results.The incidence rate of Gestational diabetes mellitus(GDM) (7.8％),gestational hypertensive (6.8％),mild preeclampsia (4.9％),premature rupture of membranes (PROM)(12.6％) and polyhydramnios(4.9％) in study group was significant higher than those in control group (2.8％,2.5％,1.9％,7.2％,1.3％).The rate of cesarean section (39.8％),macrosomia (10.7％),and neonatal hypoglycemia(4.9％)in study group was significant higher than those in control group (34.2％,6.0％,2.5％).The average birth weight in the study group was significant higher than that in the control group(3677-±351 g vs 3328 -±367g,P＜O.01).There was no significant difference in Apgar score between two groups(P ＞0.05).Conclusions:In the second trimester 75 g OGTT test normal pregnant women,poor diet and exercise management and excessive fast weight gain may increase the incidence of pregnancy complications and poorer perinatal outcomes.
