Postcesarean Thromboprophylaxis with Two Different Regimens of Bemiparin

Objectives. To compare the effectiveness of postcesarean thromboprophylaxis with two different regimens of bemiparin. Material and Methods. The study included 646 women with cesarean delivery in our hospital within a 1-year period, randomly assigned to one of two groups for prophylaxis with 3500 IU bemiparin once daily for 5 days or 3500 IU bemiparin once daily for 10 days. Results. There was one case of pulmonary embolism (first day following cesarean). An additional risk factor was present in 98.52% of the women, most frequently emergency cesarean, anemia, or obesity. The only risk factors for thromboembolic disease significantly related to pulmonary thromboembolism were placental abruption and prematurity. There were no differences in thromboembolic events among the two thromboprophylaxis regimens. Conclusions. Cesarean-related thromboembolic events were reduced in our study population due to the thromboprophylactic measures taken. Thromboprophylaxis with 3500 IU bemiparin once daily for 5 days following cesarean was sufficient to avoid thromboembolic events

Families and care providers face childbirth with uncertainty. We determined if SARS-CoV-2 infection at delivery among asymptomatic mothers had different obstetric outcomes compared to negative patients. This was a multicenter prospective study based on universal antenatal screening for SARS-CoV-2 infection. A total of 42 hospitals tested women admitted for delivery using polymerase chain reaction, from March to May 2020. We included positive mothers and a sample of negative mothers asymptomatic throughout the antenatal period, with 6-week postpartum follow-up. Association between SARS-CoV-2 and obstetric outcomes was evaluated by multivariate logistic regression analyses. In total, 174 asymptomatic SARS-CoV-2 positive pregnancies were compared with 430 asymptomatic negative pregnancies. No differences were observed between both groups in key maternal and neonatal outcomes at delivery and follow-up, with the exception of prelabor rupture of membranes at term (adjusted odds ratio 1.88, 95% confidence interval 1.13-3.11; p = 0.015). Asymptomatic SARS-CoV-2 positive mothers have higher odds of prelabor rupture of membranes at term, without an increase in perinatal complications, compared to negative mothers. Pregnant women testing positive for SARS-CoV-2 at admission for delivery should be reassured by their healthcare workers in the absence of symptoms.This project was supported by public funds 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.

Propensity score analysis of psychological intimate partner violence and preterm birth.

Psychological intimate partner violence (IPV), a global public health problem, affects mothers during pregnancy. We evaluated its relationship with preterm birth. We established a cohort of 779 consecutive mothers receiving antenatal care and giving birth in 15 public hospitals in Spain. Trained midwives collected IPV data using the Index of Spouse Abuse validated in the Spanish language. Preterm was defined as birth before 37 completed weeks of gestation. Gestational age was estimated by early ultrasound. With multivariate logistic regression we estimated the relative association of IPV with preterm birth as adjusted odds ratios (AOR), with 95% confidence intervals (CI). In propensity score analysis, using weighting by inverse probability of exposure to IPV, the whole sample was used for estimating the absolute difference in probability of preterm amongst offspring born to mothers with and without IPV. Socio-demographic and other pregnancy characteristics served as covariates in both analyses. Preterm occurred in 57 (7.3%) pregnancies. Psychological IPV, experienced by 151 (21%) mothers, was associated with preterm birth (11.9% vs 6.5%; AOR = 2.4; 95% CI = 1.1-5.0; p = 0.01). The absolute preterm difference in psychological IPV compared to normal was 0.08 (95% CI = 0.01-0.16; p = 0.04). The probability of preterm birth was 8% higher on average in women with psychological IPV during pregnancy. As our analysis controlled for selection bias, our findings give credence to a causal inference. Screening and management for psychological IPV during pregnancy is an important step in antenatal care to prevent preterm birth

Endosulfan and its metabolites in fertile women, placenta, cord blood, and human milk.

Although industrialized nations have restricted or banned many organochlorine pesticides, some of these chemicals (e.g., endosulfans) are still used, on the assumption that they pose little threat to the environment, wildlife, or human health. According to available information, Spain is the main consumer of endosulfans within the European Union, accounting for almost half of the total consumption. Reports on human exposure in Southern Spain to persistent bioacumulable organochlorine pesticides have indicated considerable exposure to endosulfans. The present study investigated the presence of endosulfan I, endosulfan II, and endosulfan metabolites in fatty and non-fatty tissues and fluids from women of reproductive age and children in Southern Spain. The highest concentration of commercial endosulfan I and endosulfan II was found in adipose tissue, with a mean value (I+II) of 17.72 ng/g lipid, followed by human milk, with a mean value (I+II) of 11.38 ng/mL milk. These findings support the lipophilicity of these chemicals and their elimination by milk secretion. The concentration in the placenta homogenate was similar to that in the blood from the umbilical cord (7.74 and 6.11 ng/mL, respectively) and reflected their lower fat content. Endosulfan diol and endosulfan sulfate were more frequently found in placenta homogenate, with a mean concentration of 12.56 and 3.57 ng/mL, respectively, and in blood from umbilical cord, at 13.23 and 2.82 ng/mL, respectively. Therefore, women of reproductive age in Southern Spain appear to be currently exposed to endosulfans. Because these chemicals can be mobilized during pregnancy and lactation, further research is warranted to investigate the health consequence in children resulting from exposure to chemicals suspected of immunotoxic, neurotoxic, or endocrine-disrupting effects

Screening for intimate partner violence during pregnancy: a test accuracy study.

Intimate partner violence (IPV) against women is a serious health problem that affects pregnancy more frequently than other obstetric complications usually evaluated in antenatal visits. We aimed to estimate the accuracy of the Women Abuse Screening Tool-Short (WAST-Short) and the Abuse Assessment Screen (AAS) for the detection of IPV during and before pregnancy. Consecutive eligible mothers in 21 public primary health antenatal care centres in Andalusia (Spain) who received antenatal care and gave birth during January 2017-March 2019, had IPV data gathered by trained midwives in the first and third pregnancy trimesters. The index tests were WAST-Short (score range 0-2; cut-off 2) and AAS (score range 0-1; cut-off 1). The reference standard was World Health Organization (WHO) IPV questionnaire. Area under receiver operating characteristics curve (AUC), sensitivity and specificity with 95% confidence intervals (CI) were estimated for test performance to capture IPV during and before pregnancy, and compared using paired samples analysis. According to the reference standard, 9.5% (47/495) and 19.4% (111/571) women suffered IPV during and before pregnancy, respectively. For capturing IPV during pregnancy in the third trimester, the WAST-Short (AUC 0.73, 95% CI 0.63, 0.81), performed better than AAS (AUC 0.57, 95% CI 0.47, 0.66, P = 0.0001). For capturing IPV before pregnancy in the first trimester, there was no significant difference between the WAST-Short (AUC 0.69, 95% CI 0.62, 0.74) and the AAS (AUC 0.69, 95% CI 0.62, 0.74, P = 0.99). The WAST-Short could be useful to screen IPV during pregnancy in antenatal visits

Evaluation of quality improvement for cesarean sections caesarean section programmes through mixed methods.

Study Protocol; Journal Article; Research Support, Non-U.S. Gov't; Erratum publicado en Implementation Science (2016) 11:37. DOI 10.1186/s13012-016-0402-xBACKGROUND The rate of avoidable caesarean sections (CS) could be reduced through multifaceted strategies focusing on the involvement of health professionals and compliance with clinical practice guidelines (CPGs). Quality improvements for CS (QICS) programmes (QICS) based on this approach, have been implemented in Canada and Spain. OBJECTIVES Their objectives are as follows: 1) Toto identify clusters in each setting with similar results in terms of cost-consequences, 2) Toto investigate whether demographic, clinical or context characteristics can distinguish these clusters, and 3) Toto explore the implementation of QICS in the 2 regions, in order to identify factors that have been facilitators in changing practices and reducing the use of obstetric intervention, as well as the challenges faced by hospitals in implementing the recommendations. METHODS Descriptive study with a quantitative and qualitative approach. 1) Cluster analysis at patient level with data from 16 hospitals in Quebec (Canada) (n = 105,348) and 15 hospitals in Andalusia (Spain) (n = 64,760). The outcome measures are CS and costs. For the cost, we will consider the intervention, delivery and complications in mother and baby, from the hospital perspective. Cluster analysis will be used to identify participants with similar patterns of CS and costs based, and t tests will be used to evaluate if the clusters differed in terms of characteristics: Hospital level (academic status of hospital, level of care, supply and demand factors), patient level (mother age, parity, gestational age, previous CS, previous pathology, presentation of the baby, baby birth weight). 2) Analysis of in-depth interviews with obstetricians and midwives in hospitals where the QICS were implemented, to explore the differences in delivery-related practices, and the importance of the different constructs for positive or negative adherence to CPGs. Dimensions: political/management level, hospital level, health professionals, mothers and their birth partner. DISCUSSION This work sets out a new approach for programme evaluation, using different techniques to make it possible to take into account the specific context where the programmes were implemented.Financiación corregida en Erratum: The authors gratefully acknowledge the funding of this research provided by the Ministry of Health and Consumers’ Affairs - –Spain (FIS Exp.

Barriers and enablers in the implementation of a program to reduce cesarean deliveries

Abstract Background Conducting audits, implementing best practices and giving feedback to the professionals have shown considerable promise in reducing rates of cesarean delivery and mother-child morbidity. The purpose of the study is two-fold: a) to identify the factors that facilitate change in current practices and thus reduce the use of obstetric interventions, and b) to better understand the barriers to such changes. To reach these objectives, the study analyzed the experiences of professionals participating in a program to reduce cesarean rates in 20 hospitals in Andalusia (Spain). Methods A qualitative exploratory study was conducted. Participants were 14 ob-gyns and 14 nurse-midwives who work for Spain’s National Healthcare System and have been involved in the program. To gather information, in-depth individual interviews were used. The interview was designed to examine factors affecting the quality of care, such as issues related to policy/management, hospitals, practitioners and patients. Results The barriers identified include: 1) At the policy/management level: limited influence of institutional policy and the scant political commitment perceived. 2) At the organizational level: separation of the hierarchical structure of doctors from that of nurse-midwives, few positive incentives and the strong threat of sanctions for malpractice, inappropriate reorganization of midwife/obgyns competences. 3) At the healthcare staff and facility level: reluctance to change accentuated by years of professional practice. 4) Physical resources: obsolete delivery rooms with a medical look. 5) At the professional level: medical and legal pressure, cesarean delivery considered safe in the event of a legal claim, low motivation due to decline in working conditions, convenience-based practices. 6) Woman giving birth and her family: fear of pain, impatience while waiting for process to occur, misinformation. The enablers include: 1) At the organizational level: good coordination with pediatrics and emergency departments, 2) Training: skills updates for a less-interventionist approach, increased awareness, 3) Health professionals: satisfaction for a job well done, recognition by patients. 4) Woman giving birth: information circuits for patients and their families, trust in health professionals. Conclusions The results can contribute to the design of more effective knowledge translation interventions to reduce cesarean sections, based on overcoming obstacles, reinforcing enabling factors and attempting to (re)define the boundaries between research and practice

Registro español de cribado de COVID-19 en gestantes asintomáticas

Background: The Spanish registry of Covid-19 in Spanish pregnant women, made up of 100 centers, is created in response to the need to know the morbidity that Covid-19 generates in pregnant women and their newborns, to know the real incidence of the disease in this population group and to establish and monitor the package of measures to improve their care. The aim of this paper was the creation of a registry of pregnant women with Covid-19 infection in order to establish the interventions and measures necessary to improve the care of these patients during hospital admission. Methods: To prepare the registry, the main researcher of each center collected weekly / biweekly the number of total pregnant women screened, as well as the total number of positive and negative, sending these data to the responsible researchers so that it could be available in real time of the percentage of infected asymptomatic pregnant population and the evolution by weeks in the centers of each participating province. The data were analyzed using the linear regression test and the Mantel test. Results: As of May 31st 2020, 16,308 screening tests were carried out in these hospitals, in which 338 pregnant women were positive, which translates into 2.07% (95% Confidence Interval: 1.86-2.30) of the asymptomatic pregnant women we attended in our centers were carriers of the virus and could develop the disease in subsequent days. Conclusions: The Spanish epidemiological registry allows us to know the incidence of infection in pregnant women attended in the Spanish delivery centers, as well as the weekly and / or fortnightly evolution of the same, observing a significant decrease in the proportion of positive pregnant women over the total of screenings throughout this period, with an average of 6.5% in early April 2020 to an average of 0.93% positive in late May 2020.Fundamentos: El registro español de Covid-19 en embarazadas españolas, integrado por 100 centros, surge en respuesta a la necesidad de conocer la morbilidad que la Covid-19 genera en las gestantes y sus recién nacidos, de conocer la incidencia real de la enfermedad en este grupo poblacional y de establecer y monitorizar el paquete de medidas para mejorar su atención. El objetivo de este estudio fue la creación de un registro de gestantes con infección por Covid-19 con la finalidad de establecer y monitorizar las intervenciones y medidas necesarias para mejorar la atención de estas pacientes durante el ingreso hospitalario. Métodos: Para la elaboración del registro, el investigador principal de cada centro recogió con carácter semanal/ quincenal el número de gestantes totales cribadas, así como el total de positivas y negativas, remitiendo a los investigadores responsables estos datos de manera que se pudiera disponer a tiempo real del porcentaje de población gestante asintomática infectada y de la evolución por semanas en los centros de cada provincia participante. Los datos fueron analizados mediante el Test de regresión lineal y test de Mantel. Resultados: A día 31 de mayo de 2020, se realizaron en estos hospitales 16.308 test de cribado, en los cuales 338 gestantes resultaron positivas, lo que se traduce en que un 2,07% (Intervalo de Confianza del 95%: 1,86-2,30) de las gestantes asintomáticas que atendimos en nuestros centros eran portadoras del virus y podían desarrollar la enfermedad en días posteriores. Conclusiones: El registro epidemiológico español permite conocer la incidencia de infección en gestantes atendidas en los paritorios españoles, así como la evolución semanal y/o quincenal de la misma, observándose un descenso significativo de la proporción de gestantes positivas sobre el total de cribadas a lo largo de este periodo, con una media del 6,5% a principios de abril de 2020 hasta una media del 0,93% de positivas a finales de mayo de 2020
