SARS-CoV-2 Infection and C-Section: A Prospective Observational Study

Pregnant women are particularly vulnerable to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. In addition to unfavorable perinatal outcomes, there has been an increase in obstetric interventions. With this study, we aimed to clarify the reasons, using Robson's classification model, and risk factors for cesarean section (C-section) in SARS-CoV-2-infected mothers and their perinatal results. This was a prospective observational study that was carried out in 79 hospitals (Spanish Obstetric Emergency Group) with a cohort of 1704 SARS-CoV-2 PCR-positive pregnant women that were registered consecutively between 26 February and 5 November 2020. The data from 1248 pregnant women who delivered vaginally (vaginal + operative vaginal) was compared with those from 456 (26.8%) who underwent a C-section. C-section patients were older with higher rates of comorbidities, in vitro fertilization and multiple pregnancies (p < 0.05) compared with women who delivered vaginally. Moreover, C-section risk was associated with the presence of pneumonia (p < 0.001) and 41.1% of C-sections in patients with pneumonia were preterm (Robson's 10th category). However, delivery care was similar between asymptomatic and mild-moderate symptomatic patients (p = 0.228) and their predisposing factors to C-section were the presence of uterine scarring (due to a previous C-section) and the induction of labor or programmed C-section for unspecified obstetric reasons. On the other hand, higher rates of hemorrhagic events, hypertensive disorders and thrombotic events were observed in the C-section group (p < 0.001 for all three outcomes), as well as for ICU admission. These findings suggest that this type of delivery was associated with the mother's clinical conditions that required a rapid and early termination of pregnancy.This project was supported by public funds that were obtained in competitive calls: Grant COV20/00021 (EUR 43,000 from the Instituto de Salud Carlos III-Spanish Ministry of Health) and co-financed with Fondo Europeo de Desarrollo Regional (FEDER) funds

Factors Associated with Failure of Bakri Balloon Tamponade for the Management of Postpartum Haemorrhage. Case Series Study and Systematic Review

Background: Postpartum haemorrhage (PPH) is an unpredictable obstetric emergency that requires a multidisciplinary approach. Bakri balloon tamponade (BBT) is recommended when PPH does not respond to medical treatment. Nowadays few published studies have performed a multivariate analysis to determine the variables independently associated with BBT failure. Methods: Our study purpose was to determine the variables independently associated with BBT failure: first, in a large single-centre cohort study between 2010 and 2020, and second, in a systematic literature review using Medline and the Cochrane Library. Maternal and perinatal variables, PPH characteristics, technique-related variables and complications were recorded in the case series study, comparing between successful and failed BBT patients. Study characteristic and variables significantly associated with BBT failure were recorded in the systematic review. All studies used a logistic regression test. Results: The case series included 123 patients. The profile of these patients were primiparous, with vaginal delivery and a full-term new-born. BBT was successful in 81.3% of cases. Five studies were included in the systematic review, providing data from 551 patients. BBT was successful in 79.5% of cases. Conclusions: Maternal age, caesarean delivery, ≥7 red blood cells units (RBCU) transfused and curettage before BBT insertion, history of caesarean section, pre-pregnancy obesity, anteriorly placed placenta, placenta accreta, caesarean delivery, estimated blood loss before insertion of BBT, long operation duration, and coagulopathy were independent factors for BBT failure

Influence of the Human Development Index on the Maternal–Perinatal Morbidity and Mortality of Pregnant Women with SARS-CoV-2 Infection: Importance for Personalized Medical Care

This study (FIS-PI18/00912) was supported by the Instituto de Salud Carlos III (Plan Estatal de I + D + i 2013–2016) and cofinanced by the European Development Regional Fund ‘‘A way to achieve Europe’’ (ERDF) and B2017/BMD-3804 MITIC-CM.Coronavirus disease-19 (COVID-19) is perhaps the most worrisome pandemic in the 21st century, having entailed devastating consequences for the whole society during the last year. Different studies have displayed an existing association between pregnancy and COVID-19 severity due to the various physiological changes that occur during gestation. Recent data identified maternal country of origin as an important determinant of COVID-19 presentation in pregnant women. However, the explanation of this fact remains to be fully elucidated. Therefore, the purpose of this work is to analyze the possible relationship between Human Development Index (HDI) of maternal country of origin with the morbimortality of pregnant women and their newborns. Here, we conducted a multicentric, ambispective, observational case-control study (1:1 ratio) and compare with the HDI of each country (group 1—very high HDI, group 2—high HDI, group 3—medium HDI, and group 4—low HDI). In total, 1347 pregnant women with confirmed SARV-CoV-2 infection (cases) were enrolled, and each was paired with one control to give a total number of 2694 participants from 81 tertiary care centers. Among the women with SARS-CoV-2 infection, more cases were produced of perinatal mortality, overall maternal morbidity, COVID-19 maternal morbidity, C-sections, hypertensive maternal morbidity, and perinatal morbidity. Our results described an inverse association between HDI and maternofetal morbidity and mortality. Moreover, the countries with an HDI lower than 1 showed higher rates of patients with maternal COVID-19-related morbidity (6.0% vs. 2.4%, p < 0.001), a need for oxygen therapy (4.7% vs. 1.8%, p < 0.001), and maternal ICU admission (2.6% vs. 1.0%, p = 0.007). Compared to other risk factors such as overweight, obesity, preexisting and obstetric comorbidities, HDI emerged as an independent risk factor explaining much of the increased maternal–perinatal morbidity and mortality detected in our group of cases. Further research is needed to establish to confirm the real impact of this factor and its components on pregnancy outcomes.Depto. de Salud Pública y Materno - InfantilFac. de MedicinaTRUEUnión EuropeaComunidad de MadridInstituto de Salud Carlos IIIpu

The Profile of the Obstetric Patients with SARS-CoV-2 Infection According to Country of Origin of the Publication: A Systematic Review of the Literature

SARS-CoV-2 is the novel member of coronavirus responsible for the worldwide pandemic COVID-19, affecting all types of people. In this context, established research identified pregnant women as a susceptible group of SARS-CoV-2 infection, although there is still limited data regarding the real impact of COVID-19 in this group. With that purpose, we conducted a systematic review describing the maternal-fetal results of pregnant women infected by SARS-CoV-2, in aim to analyze the profile of the obstetric patients according to the country of origin of the publication. A total of 38 articles were included in this systematic review with 2670 patients from 7 countries, with 20 works published from China (52.6%). We reported significative differences according to the median maternal age, with Spain as the country with the highest age (34.6 years); The percentage of tabaquism; proportion of symptomatic patients in the triage; type of radiological exam (China and France conduct CT scans on all their patients in comparison to the use of chest X-Ray in the rest of the countries studied); percentages of C-sections (83.9% in China; 35.9% Spain, p < 0.001); maternal mortality rate, proportion of patients who need treatments, the use of antivirals, antibiotics, and anticoagulants as well as measurements of the newborns. Perinatal results are favorable in the majority of countries, with very low rates of vertical transmission in the majority of works. The studies collected in this review showed moderate to high index of quality. The different works describe the affectation during the first wave of the pandemic, where the pregnant woman with SARS-CoV-2 infection is generally symptomatic during the third trimester of gestation along with other factors associated with worse prognosis of the disease, such as higher age, body mass index, and further comorbidities developed during pregnancy. In the obstetric patient, proportion of C-sections are elevated together with prematurity, increasing maternal perinatal morbimortality. Differences found between countries could be based on the proper profile of the patient in each region, the period of the pandemic directly affecting how it was managed, and the variations regarding in situ medical attention

Estudio ecográfico del timo fetal Relevancia clínica de la hipoplasia y-o involución tímica fetal en gestantes diabéticas con tratamiento insulínico

La hiperglucemia materna lleva a una situación de hiperglucemia e hiperinsulinismo fetal. Ambas situaciones crónicas tienen consecuencias en la vida fetal y en la vida adulta de estos niños. Esta demostrado que estos niños presentan una hipertrofia de todos los órganos excepto en sistema nervioso central y el timo. En los últimos años ha habido un incremento en el estudio de la medición del timo por ecografía como posible marcador de patología en estas situaciones de compromiso materno fetal. ABSTRACT. Maternal hyperglycemia may result in fetal hyperglycemia and hyperinsulinism. If those situations persist during pregnancy they will have consequences in both fetal and adult life of these children. It has been shown that these children develop hypertrophy of all their organs, except for the central nervous system and the thymus. Recently, thymus has been started to be measure by ultrasonography as a new marker for adverse fetal outcome in these situation
