Misoprostol and mid trimester termination of pregnancy in patients with two previous scars and more at Elwiya Maternity Teaching Hospital / Misoprostol e interrupção da gravidez no meio do trimestre em pacientes com duas cicatrizes anteriores e mais no Elwiya Maternity Teaching Hospital

Abstract Objectives: to determine efficiency and safety of three misoprostol regimens for 2nd trimester pregnancy termination in individuals with two or more cesarean section scars. Methods: a cross-sectional study included 100 pregnant ladies at 13th-26th weeks gestation with previous two cesarean sections (CSs) who were scheduled for pregnancy termination using misoprostol. Patients were conveniently assigned to 100µg/3h, 200µg/3h or 400 µg/3h regimens. Primary outcome was time to abortion, secondary outcomes were side effect and complications. Results: a significant association was found between number previous CSs and longer time to abortion (p=0.01). A highly significant association was identified between earlier gestational age and longer time to abortion (p<0.001). Lower side effects and complications were associated with 200 µg misoprostol every 3 hours of (p<0.001). Incomplete abortion was the most frequent recorded complication for the successive doses of misoprostol. Conclusions: misoprostol is an effective drug at low doses for pregnancy termination in women with prior two or more caesarean sections. However, its safety needs monitoring of the patient in the hospital to decrease morbidity and mortality behind its use.

Resumo Objetivos: determinar a eficiência e segurança de três regimes de misoprostol para interrupção da gravidez no segundo trimestre em indivíduos com duas ou mais cicatrizes de cesariana. Métodos: um estudo transversal incluiu 100 gestantes entre 13ª e 26ª semanas de gestação com duas cesarianas (CEs) anteriores que foram agendadas para interrupção da gravidez com uso de misoprostol. Os pacientes foram convenientemente designados para regimes de 100 µg/3 horas, 200 µg/3 horas ou 400 µg/3 horas. O desfecho primário foi o tempo para o aborto, os desfechos secundários foram efeitos colaterais e complicações. Resultados: foi encontrada associação significativa entre o número de cesáreas anteriores e o maior tempo até o aborto (p=0,01). Foi identificada associação altamente significativa entre idade gestacional mais precoce e maior tempo para abortar (p<0,001). Menores efeitos colaterais e complicações foram associados com 200 µg de misoprostol a cada 3 horas (p<0,001). O aborto incompleto foi a complicação mais frequente registrada para as doses sucessivas de misoprostol. Conclusões: o misoprostol é um medicamento eficaz em doses baixas para interrupção da gravidez em mulheres com duas ou mais cesarianas anteriores. Porém, sua segurança necessita de monitoramento do paciente no hospital para diminuir a morbimortalidade por trás de seu uso.

Role of increased plasminogen activator inhibitor-1 and vitronectin in gestational diabetes mellitus

SUMMARY OBJECTIVE: The aim of this study was to analyze the second-trimester levels of vitronectin and plasminogen activator inhibitor-1 in gestational diabetes mellitus. METHODS: This study was conducted between September 2020 and December 2020 at the University of Health Sciences, Bursa Yuksek Ihtisas Research and Training Hospital, Department of Obstetrics and Gynecology. A total of 30 pregnant women with gestational diabetes mellitus and 60 healthy controls between 24 and 27/6 weeks of gestation were included. The inclusion criteria were as follows: being between 18 and 45 years old and 24-27/6 gestational weeks, having singleton pregnancy, diagnosed with gestational diabetes mellitus by using a two-step challenge test. The exclusion criteria of this study were as follows: chronic inflammatory or infectious disease, fasting blood glucose>126 mg/dL, intolerance to glucose tolerance testing, abnormal liver or kidney function tests, as well as pregnancy with pre-gestational diabetes history of adverse perinatal outcomes. Serum vitronectin and plasminogen activator inhibitor-1 levels were measured using the enzyme-linked immunosorbent assay method. RESULTS: Vitronectin and plasminogen activator inhibitor-1 levels were higher in the gestational diabetes mellitus group compared with controls [91.85 (23.08) vs. 80.10 (39.18) ng/mL, for vitronectin and 6.50 (1.05) vs. 4.35(1.0) ng/mL, for plasminogen activator inhibitor-1 (for both p<0.001)]. vitronectin >84.7 ng/mL was found to predict gestational diabetes mellitus with a sensitivity of 70% and specificity of 63.3%. Moreover, vitronectin had a significant positive correlation with fasting blood glucose (r=0.476, p<0.001), postprandial blood glucose (r=0.489, p<0.001), HbA1c (r=0.713, p<0.001), and plasminogen activator inhibitor-1 (r=0.586, p<0.001). CONCLUSION: This study revealed that second-trimester vitronectin and plasminogen activator inhibitor-1 are increased in gestational diabetes mellitus and vitronectin could be a candidate for the prediction of gestational diabetes mellitus.

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.

An Effective Management for Thalassaemic Patients during Pregnancy

Background : Presence of thalassaemia is considered high risk in pregnancy. The present study find out the role of antenatal and intrapartum care to improve the outcome of pregnancy in thalassaemia. Materials and Method : The prospective longitudinal study was carried out on 25 patients. CBC, LFT, Ferritin, Hb electrophoresis, serial USG was done. Chorionic villous sampling was offered to thalassaemic women to decrease the number of babies born with Thalassaemia. Furthermore, management and treatment options provided to mother to overcome the incidence of maternal and neonatal complications during current pregnancy. Results : 44% of thalassaemic pregnant women had HbE ? thalassaemia, 8% ? thalassaemia major and others had thalassaemia carriers, while only 20% of their partners showed ? thalassaemia trait. All patients were anemic and during delivery mean Hb% were 8.42 g/dl, MCH 22.09 pg, MCV 73.56 fl, MCHC 29.86 g/dl and ferritin 241.51 ng/ ml. Third trimester USG exhibited 32% developed IUGR (Intrauterine growth restriction). 40% patients received blood transfusion after delivery. ? thalassaemia trait was identified in 20% babies at 6 month. Conclusion : Postpartum haemorrhage is a major complication of thalassaemia in pregnancy. After delivery a thorough neonatal check-up and haematological work-up is important for prevention of neonatal mortality and early detection of thalassaemia.

Maternal anemia in various trimesters of singleton pregnancies and its correlation with birth weight: An observational study

Background: Anemia is a very important preventable nutritional disorder affecting pregnant ladies which may have some adverse effects on the neonatal survival and development. Birth weight was correlated with changes in maternal hemoglobin concentration in various trimesters as it is important for determining child survival and development. Aims and Objectives: The aim of the study was to assess the correlation between maternal hemoglobin levels in various trimesters and neonatal birth weight. Materials and Methods: The study enrolled all pregnant women within age group 15–35 years who gave birth at Agartala Government Medical College and GBP Hospital from June 15, 2017 to August 15, 2017. Pregnant women were included into the study following delivery by simple random sampling into cases (Pregnant women who delivered low birth weight babies <2500 g) and control group (Pregnant women who delivered normal birth weight babies ?2500 g). Antenatal data were collected from hospital case sheet and labor room register. Data were analyzed using descriptive statistics and presented as Mean + SD. P < 0.05 (P < 0.05) was considered statistically significant. Results: Mean hemoglobin concentration was normal (?11 g/dl) in all three trimesters among the controls but it is found to be <11 g/dl in second and third trimesters of the case group. The mean birth weight of the babies was 2.151(± 0.2386) kg in case group and 3.047(± 0.3666) kg in control group. Conclusions: It was found that maternal hemoglobin concentration has a positive correlation (r > 0) with neonatal birth weight in all three trimesters in both cases and controls which is statistically significant (P < 0.05).

Evaluation of first- and third-trimester afamin levels in preeclampsia

SUMMARY OBJECTIVE: The aim of this study was to investigate serum afamin levels in the first and third trimesters in preeclampsia. METHODS: Serum samples from 118 patients in the first and third trimesters were analyzed. Serum samples were collected from pregnant women who had enrolled in the first trimester. Blood was then collected from pregnant women who had developed preeclampsia and from healthy controls in the third trimester. The collected blood samples were resolved for analysis, and serum afamin concentrations were measured in the first and third trimesters. Preeclampsia and healthy controls were compared. RESULTS: There was no significant difference between the control and preeclampsia groups in terms of age, body mass index, and smoking. Afamin levels in the first and third trimesters were higher in the preeclampsia group than in the control group (p<0.05). In the subgroup analysis of the preeclampsia group, afamin levels were higher in the early-onset preeclampsia group than in the late-onset preeclampsia group in the first and third trimesters (p<0.05). In the receiver operating characteristic analysis afamin levels were 96.23 ng/mL in the first trimester and 123.57 ng/mL in the third trimester as cut-off values for preeclampsia. CONCLUSION: Serum afamin levels are useful for predicting preeclampsia in the first trimester in pregnant women and can be used in clinical practice as a supportive biomarker for the diagnosis of preeclampsia in the third trimester. Meta-analyzes are needed to investigate the effect of afamin levels in the prediction and diagnosis of preeclampsia and to determine the cut-off value.

Ultrassonografia morfológica de primeiro trimestre: importante ferramenta para rastreio de aneuploidias e pré-eclâmpsia / First-trimester morphological ultrasound: important tool for aneuploidy and pre-eclampsia screening

No início do século 20, as altas taxas de mortalidade materna e infantil estimularam o desenvolvimento de um modelo de atendimento pré-natal que mantivesse características parecidas até os dias atuais. Nesse modelo, haveria maior concentração de visitas durante o final do terceiro trimestre de gestação, devido às maiores taxas de complicações nas fases finais da gestação e à dificuldade de prever a ocorrência de resultados adversos durante o primeiro trimestre. Atualmente, a avaliação clínica durante o primeiro trimestre, com auxílio da ultrassonografia e marcadores bioquímicos, pode prever uma série de complicações que acometem a gestação, incluindo cromossomopatias, pré-eclâmpsia, restrição de crescimento fetal, anomalias fetais e trabalho de parto pré-termo.

At the beginning of the 20th century, the high rates of maternal and infant mortality stimulated the development of a model of prenatal care that maintained similar characteristics until the present day. In this model, there would be a greater concentration of visits during the end of the third trimester of pregnancy, due to the higher rates of complications in the final stages of pregnancy and the difficulty in predicting the occurrence of adverse outcomes during the first trimester. Currently, clinical evaluation during the first trimester, with the aid of ultrasound and biochemical markers, can predict a series of complications that affect pregnancy, including chromosomal disorders, preeclampsia, fetal growth restriction, fetal anomalies and preterm labor.

The correlation between serum vitamin D and the risk of pre-eclampsia in the early, middle and late stages of pregnancy / 中国医师进修杂志

Objective:To investigate the correlation between serum vitamin D and the risk of pre-eclampsia at the early, middle and late stages of pregnancy.Methods:Pregnant women who registered and delivered in Electric Power Teaching Hospital of Capital Medical University from August 2020 to July 2021 were included. Pregnant women with pre-eclampsia during pregnancy were selected as the case group (150 cases), while pregnant women without any complications after delivery were selected as the control group (600 cases) according to the 1∶4 matching principle (age, pre-pregnancy body mass index and last menstruation). The levels of serum vitamin D in differences stages of pregnancy between the two groups were compared. Logistic regression model was used to analyze the association between serum vitamin D levels and the risk of pre-eclampsia.Results:The levels of serum vitamin D at the early, middle and late stages of pregnancy in the case group were lower than those in the control group: (14.32 ± 3.61) μg/L vs. (18.78 ± 4.73) μg/L, (15.06 ± 3.12) μg/L vs. (19.88 ± 4.25) μg/L, (16.04 ± 3.51) μg/L vs. (22.04 ± 5.63) μg/L, there were statistical differences ( P<0.05). Taking pregnant women with adequate serum Vitamin D as a reference, and adjusting for confounding factors such as gain weight and primipara, the risk of pre-eclampsia in early stages pregnant women with serum Vitamin D serious deficiency, middle deficiency and deficiency was increased and the OR and 95% CI were 4.84(1.25 -31.42), 3.09(1.12 - 8.96), 1.48(1.12 - 13.05); the risk of pre-eclampsia in middle stages pregnant women with serum vitamin D serious deficiency, middle deficiency and deficiency was increased and the OR(95% CI) were 4.43(1.23 - 13.55), 2.22(1.05 - 6.78), 1.12(0.45 - 7.73); the risk of pre-eclampsia in late stages pregnant women with serum vitamin D serious deficiency, middle deficiency and deficiency was increased and the OR(95% CI) were 2.13(1.12 - 8.64), 1.76(1.02 - 4.98), 1.22(0.72 - 3.94). Conclusions:The level of serum vitamin D is associated with the risk of pre-eclampsia in pregnant women in the early, middle and late stages of pregnancy, and the risk of pre-eclampsia is significantly increase when the level of serum vitamin D is severely deficient or deficient during pregnancy.

Ductus venosus as a marker of fetal growth in first trimester in a population of Colombian pregnant women / Ductus venoso como marcador de crecimiento fetal en primer trimestre en una población de gestantes colombianas

Abstract Objectives: to evaluate the relationship between the ductus venosus (DV) and the variables of fetal growth in the first trimester in a Colombian pregnant population. Methods: a descriptive cross-sectional study was carried out with secondary data obtained from a multicenter study.526 patients were included between weeks 11 and 14 for gestational ultrasound follow-up attended in three health care institutions in Bogotá, Colombia, between May 2014 and October 2018. A bivariate descriptive analysis was carried out where the relationship between the characteristics of the DV in the first trimester and ultrasound findings. Results: the flow wave of the DV in the first trimester was normal in the entire sample, with a pulsatility index of the ductus venosus (DVPI) of 0.96±0.18. In addition, a negative correlation was found between the crown-rump length (CRL) and the DVPI (p<0.05). Conclusion: there is a relationship between the DVPI regarding the CRL, indicating an interest in this early marker in relation to fetal growth alterations; however, more studies are required to determine the usefulness of this variable with respect to fetal growth.

Conclusión: existe una relación entre el IPDV respecto a la LCC, señalando un interés de este marcador temprano en relación con las alteraciones del crecimiento fetal, sin embargo, se requieren más estudios para determinar la utilidad entre esta variable respecto al crecimiento fetal

Changing Paradigms in the Initial Treatment of Ectopic Pregnancy at a University Hospital in Brazil / Mudança de paradigmas do tratamento inicial de gravidez ectópica em um hospital universitário no Brasil

Abstract Objective To evaluate the use of different treatment options for ectopic pregnancy and the frequency of severe complications in a university hospital. Methods Observational study with women with ectopic pregnancy admitted at UNICAMP Womeńs Hospital, Brazil, between 01/01/2000 and 12/31/2017. The outcome variables were the type of treatment (first choice) and the presence of severe complications. Independent variables were clinical and sociodemographic data. Statistical analysis was carried out by the Cochran-Armitage test, chi-square test, Mann-Whitney test and multiple Cox regression. Results In total 673 women were included in the study. The mean age was 29.0 years (± 6.1) and the mean gestational age was 7.7 (± 2.5). The frequency of surgical treatment decreased significantly over time (z = -4.69; p < 0.001). Conversely, there was a significant increase in the frequency of methotrexate treatment (z = 4.73; p < 0.001). Seventy-one women (10.5%) developed some type of severe complication. In the final statistical model, the prevalence of severe complications was higher in women who were diagnosed with a ruptured ectopic pregnancy at admission (PR = 2.97; 95%CI: 1.61-5.46), did not present with vaginal bleeding (PR = 2.45; 95%CI: 1.41-4.25), had never undergone laparotomy/laparoscopy (PR = 6.69; 95%CI: 1.62-27.53), had a non-tubal ectopic pregnancy (PR = 4.61; 95%CI: 1.98-10.74), and do not smoke (PR = 2.41; 95%CI: 1.08-5.36). Conclusion there was a change in the first treatment option for cases of ectopic pregnancy in the hospital during the period of analysis. Factors inherent to a disease that is more difficult to treat are related to a higher frequency of severe complications.

Métodos Estudo observacional com mulheres com gravidez ectópica admitidas no Hospital da Mulher da UNICAMP, no Brasill, entre 01/01/2000 e 31/12/2017. As variáveis de desfecho foram o tipo de tratamento (primeira escolha) e a presença de complicações graves. As variáveis independents foram dados clínicos e sociodemográficos. A análise estatística foi realizada pelo teste de Cochran-Armitage, teste de qui-quadrado, teste de Mann-Whitney e Regressão de Cox Múltipla. Resulados No total, 673 mulheres foram incluídas no estudo. A idade médica foi de 29.0 anos (± 6.1) e a idade gestacional media foi de 7.7 (± 2.5). A frequencia de tratamento cirúrgico diminuiu significativamente ao longo dos anos(z = -4.69; p < 0.001). Simultaneamente, houve um aumento da frequencia do tratamento clínico(z = 4.73; p < 0.001). Setenta e uma mulheres (10.5%) desenvolveram algum tipo de complicação grave. No modelo estatístico final, a prevalência de complicações graves foi maior nas mulheres que tiveram diagnóstico de gestação ectópica rota à admissão (PR = 2.97; 95%CI: 1.61-5.46), que não apresentaram sangramento vaginal (PR = 2.45; 95%CI: 1.41-4.25), sem antecedentes de laparotomia/laparoscopia (PR = 6.69; 95%CI: 1.62-27.53), com gravidez ectópica não-tubária (PR = 4.61; 95%CI: 1.98-10.74), e não tabagistas (PR = 2.41; 95%CI: 1.08-5.36). Conclusão Houve uma mudança na escolha do primeiro tratamento indicado nos casos de gravidez ectópica durante o período analisado. Os fatores inerentes a doença relacionados a maior dificuldade de tratamento foram associados a maior frequencia de complicações graves.

Anomalías congénitas disruptivas asociadas con misoprostol. Reporte de un caso / Disruptive congenital anomalies associated with misoprostol. Case report

Resumen ANTECEDENTES: La exposición prenatal al misoprostol puede asociarse con un espectro de defectos congénitos que varían desde anomalías del sistema nervioso central, secuencia de Moebius, defectos en la pared abdominal, defectos transversales en las extremidades hasta alteraciones fetales. Esos defectos se observan más comúnmente con esquemas de solo misoprostol para inducción del aborto. Por esos antecedentes es importante que la historia clínica de toda paciente obstétrica sea exhaustiva para permitir identificar el antecedente de la exposición prenatal luego de un aborto fallido. CASO CLINICO: Paciente de 21 años, con 32 semanas de embarazo, con diagnóstico de feto con ventriculomegalia. En la evaluación ecográfica destacó la ventriculomegalia triventricular severa, simétrica y la angulación de ambas extremidades inferiores en varo. La resonancia magnética reportó: ventriculomegalia no comunicante severa, bilateral, simétrica, por probable estenosis del acueducto de Silvio. Cariotipo 46,XY y perfil TORCH negativo. El embarazo finalizó mediante cesárea, por indicación fetal a las 35 semanas. La evaluación al nacimiento reportó: parálisis facial bilateral, macrocefalia y pie equino varo bilateral. Al volver a interrogar a la paciente refirió haber sido tratada con misoprostol en el primer trimestre del embarazo, con fines abortivos. Al descartar las alteraciones cromosómicas e infecciosas se estableció el diagnóstico de secuencia Moebius. CONCLUSIONES: La exposición prenatal al misoprostol está relacionada con la aparición de defectos vasculares en algunos fetos expuestos. Aún no se ha determinado el espectro preciso ni la estimación potencial de teratogenicidad. La historia clínica es el pilar para la asociación en estos casos.

Abstract BACKGROUND: Prenatal misoprostol exposure can be associated with a spectrum of birth defects, ranging from central nervous system abnormalities, Moebius sequence, abdominal wall defects, as well as transverse limb defects, fetal abnormalities are more commonly seen with the use of the misoprostol-only regimen for induction of abortion, such that a thorough medical history is essential to detect a history of prenatal exposure after a failed abortion. CLINICAL CASE: A 21-year-old patient, with a 32-week pregnancy, who attended the institute with a diagnosis of a fetus with ventriculomegaly, the ultrasound evaluation highlighted severe symmetric triventricular ventriculomegaly and angulation of both lower extremities in varus, magnetic resonance imaging reported severe non-communicating ventriculomegaly Symmetric bilateral, due to probable stenosis of the aqueduct of Silvio, the karyotype reported 46, XY, as well as a negative TORCH profile, however, a cesarean section was performed for fetal indication at 35 weeks, the evaluation at birth showed bilateral facial paralysis, macrocephaly and foot Bilateral equinus varus, upon re-examination the patient referred the use of misoprostol in the first trimester of pregnancy for abortive purposes, so as there were no chromosomal or infectious alterations, a Moebius sequence was suggested. CONCLUSIONS : Prenatal exposure to misoprostol is related to the appearance of vascular disruption defects in some exposed fetuses, the precise spectrum and potential estimation of teratogenicity have not yet been determined, the clinical history is the mainstay for the association in these cases.

Significado clínico del diagnóstico prenatal de la protuberancia corial en el tamizaje del primer trimestre de la gestación / Clinical significance of prenatal diagnosis of chorionic bump in the first trimester screening

Resumen OBJETIVO: Determinar el significado clínico y el desenlace obstétrico y perinatal luego de la detección de una protuberancia corial en el estudio de tamizaje del primer trimestre de la gestación. MATERIALES Y MÉTODOS: Estudio de cohorte prospectiva efectuado, de abril del 2019 a diciembre 2021, en pacientes referidas para tamizaje del primer trimestre a una unidad de Medicina y Cirugía Fetal de tercer nivel de referencia (Prenatalia Medicina Fetal San Javier, Guadalajara, Jalisco, México). Criterio de inclusión: pacientes con medición de la longitud cráneo caudal comprendida entre 45 y 84 mm durante el tamizaje prenatal del primer trimestre. Se reportaron los hallazgos ecográficos, se obtuvieron información y datos clínicos relevantes de los expedientes electrónicos y cuando se consideró necesario se contactó al ginecoobstetra tratante y a las pacientes. Se utilizó estadística descriptiva con medidas de tendencia central y dispersión. Para el análisis comparativo se utilizó χ2 y U de Mann Whitney para contrastar diferencias entre grupos. RESULTADOS: Se evaluaron 1359 embarazos y la protuberancia corial se documentó en 19 de ellos. En 9 de 19 casos se asoció con sangrado del primer trimestre, previo a la exploración ecográfica. En 16 de 19 casos se encontraron dimensiones de la protuberancia corial mayores a 10 mm. Además, la protuberancia se asoció con episodios de amenaza de parto pretérmino en 13 de los 19 casos. CONCLUSIONES: La protuberancia corial es un hallazgo poco frecuente durante el tamizaje del primer trimestre que se asocia con sangrado y episodios de amenaza de parto pretérmino.

Abstract OBJECTIVE: To determine the clinical significance and obstetric and perinatal outcome after detection of a chorionic protrusion in the first trimester screening study. MATERIALS AND METHODS: Prospective cohort study performed in patients referred for first trimester screening to a third level referral Fetal Medicine and Surgery unit (Prenatalia Medicina Fetal San Javier, Guadalajara, Jalisco, Mexico) from April 2019 to December 2021. Patients with craniocaudal length measurements between 45 and 84 mm during first-trimester prenatal screening were included. Ultrasound findings were reported, relevant clinical information and data were obtained from electronic records, and the treating obstetrician-gynecologist and patients were contacted when necessary. Descriptive statistics with measures of central tendency and dispersion were used. For comparative analysis, 2 and Mann Whitney U were used to contrast differences between groups. RESULTS: 1359 pregnancies were evaluated and chorionic protrusion was documented in 19 of them. In 9 of 19 cases it was associated with first trimester bleeding prior to ultrasound examination. Chorionic protrusion was found to be larger than 10 mm in 16 out of 19 cases. In addition, the protrusion was associated with episodes of threatened preterm labour in 13 of 19 cases. CONCLUSIONS: Chorionic protrusion is a rare finding during first trimester screening that is associated with bleeding and episodes of threatened preterm labour.

Lipid metabolism in late pregnancy and its correlation with adverse perinatal outcome among Tibetan pregnant women in high altitudes / 中华围产医学杂志

Objective:To analyze the lipid levels, adverse perinatal outcome and their correlation in Tibetan pregnant women in high altitudes in late pregnancy.Methods:Retrospective analysis was performed on clinical and laboratory data of 523 Tibetan singleton pregnant women who delivered after 28 weeks at the Department of Obstetrics and Gynecology, Chaya People's Hospital, Changdu City. The subjects were divided into three groups according to the altitude of their long-term residence, including altitude<3 500 m (Group A, n=161), altitude ≥3 500 m and <4 000 m (Group B, n=203) and altitude≥4 000 m (Group C, n=159). In addition, the subjects were also grouped into high TG group (TG≥3.23 mmol/L, n=80) and control group (TG<3.23 mmol/L, n=443). The baseline information, levels of lipid and perinatal outcome were compared among Group A,B and C, and also between the high TG and control group, respectively, using Mann-whitney U test, Kruskal-Wallis H test, LSD- t, Chi-square test, or Fisher exact test. Multivariate logistic regression analysis was also applied to analyze the correlation between hypertriglyceridemia and adverse perinatal outcome. Results:The maternal age, gravidity and parity, body mess index, blood pressure on admission and total cholesterol (TC), TG, high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C), TG/HDL-C ratio and LDL-C/HDL-C ratio in late pregnancy and the occurrence of adverse perinatal outcome did not show any significant differences among Group A, B and C (all P>0.05). However, the hemoglobin (Hb) level increased with the elevation of altitude as expected, and that in Group C was higher than that in Group A and B [121.0 g/L (108.0-132.0 g/L) vs 115.0 g/L (103.5-128.0 g/L) and 117.0 g/L (101.0-127.0 g/L), H=2.37 and 1.97, both P<0.05]. The proportion of women with hypertriglyceridemia, the high TG group, in late pregnancy was 15.3% (80/523), and no significant difference was found in HDL-C or Hb levels between the high TG and control group [1.7 mmol/L (1.5-2.0 mmol/L) vs 1.8 mmol/L (1.5-2.1 mmol/L), Z=－1.51;123.5 g/L (110.0-131.8 g/L) vs 117.0 g/L (104.0-128.0 g/L), Z=1.69; both P>0.05]. Higher rates of cesarean section [13.8% (11/80) vs 6.6% (29/443), χ2＝4.98], hypertensive disorders of pregnancy (HDP) [16.3% (13/80) vs 7.5% (33/443), χ2＝6.54], preeclampsia (PE) [8.8% (7/80) vs 1.6% (7/443), χ2＝13.37], hyperglycemia during pregnancy [11.3%( 9/80) vs 3.6% (16/443), χ2＝8.69], preterm birth (PB) [7.5% (6/80) vs 2.0% (9/443), χ2＝7.27], microsomia [5.0% (4/80) vs 0.9% (4/443), Fisher exact test] and neonatal asphyxia [8.8%(7/80) vs 2.5% (11/443), χ2＝8.01] were observed in the high TG group than in the control group (all P<0.05). Regarding the pregnant women at different altitude, TG was negatively correlated with Hb ( r=－0.17, P=0.037) only in Group C .Multivariate logistic regression analysis revealed higher risk of HDP ( OR=2.42,95% CI:1.17-5.00), PE ( OR=5.25, 95% CI:1.73-16.00), hyperglycemia during pregnancy ( OR=3.77, 95% CI:1.56-9.09), PB ( OR=4.33, 95% CI:1.42-13.22), microsomia ( OR=4.33, 95% CI:1.42-13.22), neonatal asphyxia ( OR=3.45, 95% CI:1.27-9.35) and fetal demise ( OR=4.94, 95% CI:1.01-24.21) in women with high TG level in late pregnancy (all P<0.05). Conclusions:There were no differences in adverse perinatal outcomes or serum lipid levels in late pregnancy among women living at different high altitudes. However, hypertriglyceridemia at the third trimester is closely associated with the incidence of HDP, PE, hyperglycemia during pregnancy, PB, microsomia, neonatal asphyxia and fetal demise in this group of women.

Effectiveness and safety of intra-amniotic ethacridine injection for third trimester induction due to fetal demise / 中华围产医学杂志

Objective:To study the effectiveness and safety of intra-amniotic ethacridine injection in pregnancy induction at ≥28 gestational weeks due to fetal demise.Methods:This retrospective study recruited 77 singleton pregnant women who were admitted to Peking University First Hospital at ≥28 gestational weeks, from January 1, 2011 to December 31, 2021, because of fetal demise diagnosed by ultrasound. Four groups were classified according to different methods of induction, including ethacridine success group ( n=63), ethacridine failure group ( n=4), mifepristone plus misoprostol group ( n=5), and spontaneous delivery group ( n=5). Those in the ethacridine success group were further divided into scarred and non-scarred uterus group. The differences in general conditions and delivery outcomes among these women were analyzed using t-test, one-way analysis of variance, Chi-square test, and Mann-Whitney U test or Kruskal-Wallis H test. Results:(1) Among the 67 patients induced by ethacridine, the success rate was 94.0% (63/67). (2) Compared the ethacridine success group with the mifepristone plus misoprostol group or spontaneous delivery group, respectively, there was no significant difference in total labor duration, intrapartum hemorrhage volume, weight of the dead fetus, and the incidence of postpartum hemorrhage, perineal laceration, and intrauterine residue (all P>0.05). No serious complications such as placental abruption, disseminated intravascular coagulation, intrauterine infection, uterine rupture, conversion to cesarean section, or puerperal infection occurred in the three groups. (3) The duration between ethacridine injection and labor onset was shorter in the ethacridine success group than in the mifepristone plus misoprostol group [(28.5±12.0) h vs (54.2±17.6) h, t=－4.45, P<0.001]. (4) Among the 63 cases of ethacridine success group, the outcomes after induction were similar between scarred and non-scarred uterus group (all P>0.05). (5) The median duration between ethacridine injection and labor onset in the ethacridine success group was 26.8 h (2.3-66.0 h), which meant 95% of the patients went into labor within 51.7 h and 100% within 66 h after the injection. Conclusion:Intra-amniotic injection of ethacridine is safe and effective in termination for singleton pregnancy due to fetal demise at the third trimester and the duration from drug administration to labor onset was significantly shorter than that of mifepristone plus misoprostol, without increasing the risk of any complications.

Acute adverse events and pregnancy outcome after inactivated COVID-19 vaccination in first trimester / 中华围产医学杂志

Objective:To investigate acute adverse events and pregnancy outcome after vaccination of inactivated COVID-19 vaccine in the first trimester of pregnancy.Methods:The retrospective-prospective cohort study was conducted among pregnant women of 11-13 +6 weeks of gestation who visited the obstetric clinics for prenatal check in Lianyungang Maternal and Child Health Hospital from May to November in 2021, after registration for perinatal health cards in the community. Those who met the inclusion criteria were recruited and were divided into vaccination group and non-vaccination group according to whether they received inactivated COVID-19 vaccine in the first trimester. Women in the vaccination group were further divided into 1-dose group and 2-dose group. Information, including pregnancy-related screening, pregnancy complications, pregnancy outcome and acute adverse events, were collected and compared with independent samples t-test or ANOVA, Kruskal- Wallis H test or Mann-Whitney U test, χ2 test or Fisher's exact probability method. Results:Totally, 105 pregnant women were analyzed in 1-dose group, 90 in 2-dose group, and 194 in non-vaccination group. (1) There were no statistically significant differences in the occurrence of acute adverse events [1-dose group: 2.86% (3/105); 2-dose group: 6.67% (6/90); non-vaccination group: 4.63% (9/194); χ2=1.59; vaccination group was 4.61% (9/195), when compared with non-vaccination group, χ2=0.00], abnormal pregnancy-related screening indicators and abnormal pregnancy outcome among the three groups (all P>0.05), neither between the vaccination and non-vaccination group (all P>0.05). The acute adverse events in these women included fever, pain at the inoculation site, fatigue, local induration and rash.(2) The differences in hypertensive disorders in pregnancy among the three groups were statistically significant [1-dose group: 10.5%(11/105); 2-dose group: 17.8%(16/90); non-vaccination group: 7.7%(15/194); χ2=6.46, P=0.040], and the incidence was higher in the 2-dose group than that in the non-vaccination group (adjusted by Bonferroni, P<0.017). (3) Regarding other pregnancy complications, no difference was found among the three groups (all P>0.05), neither between the vaccination and non-vaccination group (all P>0.05). Conclusion:The risk of acute adverse events and adverse pregnancy outcome is similar in pregnant women who received inactivated COVID-19 vaccine versus those who did not in the first trimester, and regular blood pressure monitoring is recommended for those who received two doses of inactivated COVID-19 vaccine.

Ultrasonographic diagnosis and prognosis of transposition of the great arteries at 11-13 + 6 weeks gestation / 中华超声影像学杂志

Objective:To investigate the value of ultrasonography in diagnosis of transposition of great arteries of the fetus at 11-13 + 6 weeks gestation. Methods:A prospective study was conducted on fetuses screened by ultrasound in the first trimester in Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region between January 2015 and March 2022. Fetal heart structure was screened by three-section screening method. Fetuses with suspected transposition of the great arteries at 11-13 + 6 weeks gestation underwent followed-up ultrasound examination, chromosome and gene test results. The ultrasound characteristics and prognosis pregnancy outcomes were summarized. Results:Twenty-one cases of transposition of the great arteries were detected by ultrasonography, including complete transposition of great arteries (20 cases) and congenitaly corrected transposition of the great arteries (1 case). Two cases were miss diagnosed. Twenty-one cases showed parallel signs of two major arteries on grayscale outflow section at 11-13 + 6 weeks gestation. There were 6 cases with aneuploid ultrasonographic soft markers abnormality, 2 cases with extracardiac malformation. Chromosome and microarray analysis were performed in 13 cases. 4 cases with chromosomal abnormality. Four cases of chromosomal abnormalities were associated with ultrasonographic soft markers abnormality, and 1 case with extracardiac malformation.In the 23 cases, 20 cases were induced, 1 miscarried, and 2 delivered to term. Among the fetuses delivered at term, 1 case died before neonatal operation and 1 case survived. Conclusions:Standardized ultrasound scan at 11-13 + 6 weeks has high accuracy in diagnosis of transposition of the great arteries. And the incidence of chromosomal abnormality is high with ultrasonographic soft markers abnormality or extracardiac malformation.

Cambios de adiposidad corporal entre la captación del embarazo y el posparto a corto plazo

Introducción: Las acumulaciones excesivas de tejido adiposo, general o regional, constituyen hallazgos de valor clínico en el seguimiento nutricional y cardiometabólico durante la gestación y en el período posparto. Objetivo: Describir los cambios en la adiposidad corporal trascurridos 18 meses después del parto. Método: Se realizó un estudio observacional descriptivo de la adiposidad corporal, entre enero 2017 y agosto 2018, en 119 mujeres en el posparto a corto plazo, cuya adiposidad corporal se había estudiado al momento de la captación en el policlínico "Chiqui Gómez Lubián". Resultados: En el posparto con respecto al momento de la captación, se observó una disminución de las mujeres sin adiposidad general de 28,6 % a 21,8 % y de las mujeres con adiposidad general intermedia de 62,2 % a 53,8 %; con un aumento marcado de aquellas con adiposidad general alta de 9,2 % a 24,4 %. Aumentó la cantidad de mujeres con adiposidad central alta de 35,3 % a 43,7 % y disminuyeron las mujeres sin adiposidad central de 64,7 % a 56,3 %. Conclusiones: Evaluar los cambios de la adiposidad corporal por técnicas antropométricas sencillas y de fácil acceso, durante el embarazo y en el posparto a corto plazo, puede ofrecer información de utilidad para una mejor orientación del seguimiento de la salud cardiometabólica de la mujer.

Introduction: Excessive accumulations of adipose tissue, whether general or regional, are findings of clinical value in nutritional and cardiometabolic follow-up during pregnancy and in the postpartum period. Objective: To describe the changes in body adiposity at eighteenth months after delivery. Methods: A descriptive and observational study of body adiposity was carried from January 2017 to August 2018 in 119 women in the short-term postpartum period, whose body adiposity had been studied during the first antenatal visit at "Chiqui Gómez Lubián" Polyclinic. Results: In the postpartum period, with respect to the first antenatal visit, a decrease was observed in the number of women without general adiposity (from 28.6 % to 21.8 %) and of women with intermediate general adiposity (from 62.2 % to 53.8 %), with a marked increase in the number of women with high general adiposity (from 9.2 % to 24.4 %). The number of women with high central adiposity increased (from 35.3 % to 43.7 %), while the number of women without central adiposity decreased (from 64.7 % to 56.3 %). Conclusions: To evaluate the changes in body adiposity by simple and easily accessible anthropometric techniques, during pregnancy and in the short-term postpartum period, may provide useful information for designing better the follow-up of cardiometabolic health of women.

Medical versus surgical method of pregnancy termination during first trimester

Background: Medical as well as surgical methods for abortion is performed worldwide since many years. Medical methods are safe till first trimester of pregnancy. The present study is intended to compare success rate and side effects of both method of abortion during first trimester. Aims and Objectives: The aim of the study was to study and compare the success rate in both the methods of termination of pregnancy in first trimester and to study side effects and complications as well as satisfaction among study participants undergoing termination of pregnancy during first trimester in both methods. Materials and Methods: A prospective comparative study was conducted at the Department of Obstetrics and Gynecology of one of the teaching medical institute of Ahmedabad among women seeking Medical termination of pregnancy with less than or equal to 9 weeks of gestation. Total 150 participants were selected using purposive sampling (75 in each group). Group A consist of patients having medical termination of pregnancy by medical method and Group B consist of cases that required termination of pregnancy by surgical method. Results: Mean age of the patients in Group A was 27.98 � 4.57 years and Group B was 27.58 � 4.22 years. Proportion of complete abortion in medical and surgical method was 88% and 96%, respectively. Surgical method had more effectiveness and success rate for complete abortion as compare to medical method. The mean duration of bleeding per vagina in both groups were more among Group A. Abdominal pain and gastrointestinal symptoms such as nausea, vomiting, diarrhea, and fever were also found to be more in Group A as compared to Group B. Those who had medical method were more satisfied than surgical method. Conclusion: Both methods are safe and effective as far as termination of first trimester pregnancy is concerned. Proper counseling with appropriate selection can bring safe and effective outcome in first trimester of termination of pregnancy

Supresión de la visita de tercer trimestre en embarazo de bajo riesgo en la pandemia de SARS-CoV-2 / Third trimester suppression in low-risk pregnancy in the SARS-CoV-2 pandemic

Resumen Objetivo: La pandemia de SARS-CoV-2 ha obligado a una reorganización de las visitas presenciales, y por ese motivo se han minimizado hasta el punto de reconsiderar la realización de la visita del tercer trimestre. Nuestro centro suprimió dicha visita obstétrica y obtuvo datos propios para comparar los resultados perinatales logrados con dicho manejo. Método: Se realizó un estudio de cohortes retrospectivo, en marzo de 2020, con una cohorte con visita presencial única en la semana 40 de gestación (122 gestantes) frente a una cohorte con seguimiento convencional con visita presencial en la semana 36 de gestación (162 gestantes). Se evaluaron la restricción del crecimiento fetal, la edad gestacional al nacimiento, el peso neonatal y las tasas de inducciones, partos eutócicos y cesáreas urgentes en trabajo de parto. Resultados: Se encontraron diferencias leves en la tasa de nuliparidad (p < 0,04), sin hallarlas en el resto de las variables maternas. No hubo diferencias entre las dos cohortes en los resultados neonatales. Conclusiones: No hay diferencias entre los resultados materno-fetales obtenidos en gestantes con seguimiento gestacional con restricción de la visita del tercer trimestre respecto del seguimiento tradicional, excepto en el diagnóstico de las alteraciones de la estática fetal al término de la gestación.

Abstract Objective: The SARS-CoV-2 pandemic has forced a reorganization of face-to-face visits, for this reason they have been minimized to the point of reconsidering the completion of the third trimester visit. Our center eliminated the performance of this obstetric visit and obtained its own data to compare the perinatal results obtained with such management. Method: A retrospective cohort study was carried out in March 2020, with a cohort with a single face-to-face visit at 40th week of gestation (122 pregnant women), versus a cohort with conventional follow-up with face-to-face visit at 36th week of gestation (162 pregnant women). The following were evaluated fetal growth restriction, gestational age at birth, neonatal weight, rate of inductions, of eutocic deliveries, and of urgent cesarean sections in labor. Results: Slight differences were found in the nulliparity rate (p < 0.04), without finding them in the rest of the maternal variables. There were no differences between the two cohorts in neonatal outcomes. Conclusions: There were no differences between the maternal-fetal results obtained in pregnant women with gestational follow-up with restriction of the third trimester visit compared to traditional follow-up, except in the diagnosis of alterations in fetal statics at the end of pregnancy.

Asociación entre el hipotiroidismo subclínico de anticuerpos antiperoxidasa tiroidea negativos y los resultados perinatales adversos diagnosticados con diferentes criterios en el tercer trimestre del embarazo

Antecedentes. El efecto del hipotiroidismo subclínico (HSC) en los resultados perinatales adversos no está claro, y los valores de referencia de la hormona tiroestimulante (TSH) en el embarazo son controvertidos. Objetivo. Evaluar los efectos del HSC negativo para los anticuerpos de la peroxidasa tiroidea (TPOAbs) sobre los resultados perinatales según los diferentes valores de referencia de la TSH. Métodos. Un total de 554 mujeres embarazadas, incluyendo 509 eutiroideas y 45 gestantes hipotiroideas subclínicas (TSH > 3 mIU/L), fueron incluidas en este estudio prospectivo de casos y controles. Todas las gestantes estaban en el tercer trimestre y eran negativas a los TPOAbs. Las funciones tiroideas fueron evaluadas utilizando los valores de referencia específicos para el trimestre recomendados por el Colegio Americano de Obstetricia y Ginecología (ACOG) (TSH > 3 mIU/L) y la Asociación Americana de Tiroides (ATA) (TSH > 4 mIU/L). Resultados. La mortalidad neonatal en el hipotiroidismo subclínico con un límite superior de TSH de 4 mIU/L fue significativamente menor que en el grupo eutiroideo (2 (0,4%) frente a 1 (4,5%); p=0,009). No hubo diferencias significativas en resultados maternos y perinatales adversos en las gestantes con HSC y eutiroideas en ambos valores de referencia de la TSH. No hubo correlación significativa entre los valores de TSH y las semanas de parto de las gestantes con parto prematuro (r=0,169, p=0,146). Conclusiones. En este estudio, utilizando los diferentes valores basales de TSH recomendados por las directrices del ACOG de 2020 y de la ATA de 2017 en el tercer trimestre del embarazo para el diagnóstico de hipotiroidismo subclínico, no hubo una relación significativa entre los casos de hipotiroidismo subclínico con TPOAbs negativos y los resultados perinatales adversos.

Background: The effect of subclinical hypothyroidism (SCH) on adverse perinatal outcomes is unclear, and thyroid-stimulating hormone (TSH) reference values in pregnancy are controversial. Objective: To evaluate the effects of thyroid peroxidase antibody (TPOAbs) negative SCH on perinatal outcomes according to the different TSH reference values. Methods: A total of 554 pregnant women, including 509 euthyroid and 45 subclinical hypothyroid (TSH > 3 mIU/L) pregnant women, were included in this prospective case-controlled study. All pregnant women were in the third trimester and were TPOAbs negative. Thyroid functions were evaluated using trimester-specific reference values recommended by the American College of Obstetrics and Gynecology (ACOG) (TSH > 3 mIU/L) and the American Thyroid Association (ATA) (TSH > 4 mIU/L) guidelines. Results: Neonatal mortality in subclinical hypothyroidism with a TSH upper limit of 4 mIU/L was significantly lower than in the euthyroid group (2 (0.4%) vs 1 (4.5%); p=0.009). There was no significant difference in terms of adverse maternal and perinatal outcomes in SCH and euthyroid pregnant women in both TSH reference values. There was no significant correlation between TSH values and delivery weeks of pregnant women with preterm delivery (r=0.169, p=0.146). Conclusions: In this study, using different baseline TSH values recommended by the 2020 ACOG and 2017 ATA guidelines in the third trimester of pregnancy for the diagnosis of subclinical hypothyroidism, it was shown that there was no significant relationship between cases of subclinical hypothyroidism with negative TPOAbs and adverse perinatal outcomes.
