European guidelines on perinatal care: corticosteroids for women at risk of preterm birth

of recommendationsCorticosteroids should be administered to women at a gestational age between 24⁺⁰ and 33⁺⁶weeks, when preterm birth is anticipated in the next seven days, as these have been consistently shown to reduce neonatal mortality and morbidity. (Strong-quality evidence; strong recommendation). In selected cases, extension of this period up to 34⁺⁶weeks may be considered (Expert opinion). Optimal benefits are found in infants delivered within 7 days of corticosteroid administration. Even a single-dose administration should be given to women with imminent preterm birth, as this is likely to improve neurodevelopmental outcome (Moderate-quality evidence; conditional recommendation).Either betamethasone (12 mg administered intramuscularly twice, 24-hours apart) or dexamethasone (6 mg administered intramuscularly in four doses, 12-hours apart, or 12 mg administered intramuscularly twice, 24-hours apart), may be used (Moderate-quality evidence; Strong recommendation). Administration of two "all" doses is named a "course of corticosteroids".Administration between 22⁺⁰ and 23⁺⁶weeks should be considered when preterm birth is anticipated in the next seven days and active newborn life-support is indicated, taking into account parental wishes. Clear survival benefit has been observed in these cases, but the impact on short-term neurological and respiratory function, as well as long-term neurodevelopmental outcome is still unclear (Low/moderate-quality evidence; Weak recommendation).Administration between 34 + 0 and 34 + 6 weeks should only be offered to a few selected cases (Expert opinion). Administration between 35⁺⁰ and 36⁺⁶weeks should be restricted to prospective randomized trials. Current evidence suggests that although corticosteroids reduce the incidence of transient tachypnea of the newborn, they do not affect the incidence of respiratory distress syndrome, and they increase neonatal hypoglycemia. Long-term safety data are lacking (Moderate quality evidence; Conditional recommendation).Administration in pregnancies beyond 37⁺⁰weeks is not indicated, even for scheduled cesarean delivery, as current evidence does not suggest benefit and the long-term effects remain unknown (Low-quality evidence; Conditional recommendation).Administration should be given in twin pregnancies, with the same indication and doses as for singletons. However, existing evidence suggests that it should be reserved for pregnancies at high-risk of delivering within a 7-day interval (Low-quality evidence; Conditional recommendation). Maternal diabetes mellitus is not a contraindication to the use of antenatal corticosteroids (Moderate quality evidence; Strong recommendation).A single repeat course of corticosteroids can be considered in pregnancies at less than 34⁺⁰weeks gestation, if the previous course was completed more than seven days earlier, and there is a renewed risk of imminent delivery (Low-quality evidence; Conditional recommendation).

Fetal death from SARS-CoV-2 mediated acute placental failure

INTRODUCTION

We demonstrate the nonlinear severity of symptoms of SARS-CoV-2 infection in the mother leading to fetal death after acute placental failure.

METHODS

Careful clinical evaluation, real-time RT-PCR molecular microbiologic testing, isolation of a viable virus, and autopsy with histologic results were used to investigate the possible vertical transmission of SARS-CoV-2 infection from mother to fetus.

RESULTS

Histologic changes in the placenta correlate with SARS-CoV-2 infection. Total nucleic acid isolated from vaginal swabs, fresh placental tissue, and deparaffinized tissue showed a high viral load of SARS-CoV-2. Complete genome sequencing confirmed the presence of the SARS-CoV-2 Delta variant.

DISCUSSION

Several methods have been used to confirm SARS-CoV-2-mediated acute placental failure, all of which were conclusive. It should be noted that careful periodic fetal well-being checks are required in women infected with SARS-CoV-2, regardless of the severity of symptoms. Most of the cases described with fetal death occurred in the third trimester.

The impact of the COVID-19 pandemic on organised cervical cancer screening: The first results of the Slovenian cervical screening programme and registry

BACKGROUND

The COVID-19 pandemic threatens the impact of cervical cancer screening and global cervical cancer elimination goals. As cervical cancer screening programmes were adjusting to the new situation, we evaluated the intensity, quality, and outcomes of cervical cancer screening in Slovenia in the first seven months of the pandemic.

METHODS

Historical observational study on data from a population-based cervical cancer screening registry. Number of cervical cytopathology (screening and follow-up), histopathology (diagnostic procedures, invasive procedures and number of newly diagnosed CIN2+ cases) and HPV test results from the entire Slovenian women population between January 1st and September 30th 2020 were compared to a three-year average of the years 2017-19.

FINDINGS

A two-month screening lock-down between March 12th and May 8th 2020 resulted in an epidemic deficit of screening (-92%), follow-up (-70%), and HPV triage tests (-68%), as well as invasive diagnostic (-47%) and treatment (-15%) of cervical lesions. Time to diagnosis and treatment did not increase; times to laboratory results fluctuated but stayed within standards. Slovenia has entered the second epidemic intending to add as little as possible to the pandemic deficit of screening smears (-23%) and yearly CIN2+ cases (-10%). Women aged 30-39 were most affected, with the highest pandemic deficit of screening smears (-26%) and yearly CIN2+ cases (-19%).

INTERPRETATION

The pandemic has deeply affected all levels of our lives. New vulnerable groups and inequalities have emerged that require recognition and action. To prevent long-term increases in the cervical cancer burden due to the COVID-19 pandemic, it is crucial that organised screening is maintained and monitored in settings where it can be safely and comprehensively provided.

FUNDING

None.

Usefulness of COVID-19 screen-and-test approach in pregnant women: an experience from a country with low COVID-19 burden

OBJECTIVES

Information on the usefulness of screen-and-test strategies of pregnant women for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is lacking.

METHODS

We retrospectively reviewed the Ljubljana Maternity Hospital database and searched for pregnant women, who were admitted to the hospital between March 15 and May 16, 2020, for a planned procedure or hospitalization. Their medical records were examined and SARS-CoV-2 test results were retrieved.

RESULTS

During the two-month period analyzed, there were a total of 265 scheduled admissions of pregnant women to our hospital. Two hundred two (76.2%) were tested for SARS-CoV-2 1 day prior to admission. All tested negative for SARS-CoV-2 RNA, regardless of having coronavirus disease 2019 (COVID-19)-compatible signs or symptoms (n=28) or not (n=174).

CONCLUSIONS

In a population with a low SARS-CoV-2 burden, usefulness of universal testing of pregnant women before admission to the hospital is limited. We recommend that obstetric units in regions with low SARS-CoV-2 burden enforce rational use of personal protective equipment and diligent screening protocols using targeted questionnaires, whereas SARS-CoV-2 laboratory testing should be performed only in screen-positives: those with high clinical suspicion of COVID-19 and/or suspected epidemiological history.

Establishing a Differential Marker Profile for Pregnancy Complications Near Delivery

OBJECTIVE

The aim of this work was to define a differential marker profile for pregnancy complications near delivery.

METHODS

We enrolled pregnant women who were referred to the outpatient pregnancy clinic of the University Medical Center, Ljubljana, Slovenia, due to symptoms of pregnancy complications and women with a history of pregnancy complications attending the high-risk hospital clinic for close surveillance. They were evaluated for prior risk and were tested for biophysical and biochemical markers at the time of enrolment. Biochemical markers included the pro- and anti-angiogenic markers, along with additional previously reported markers of potential value, all tested by various formats of immuno-diagnostics. Biophysical markers included blood pressure, sonographic markers, and EndoPAT. Statistical differences were determined with Kruskal-Wallis and Mann-Whitney tests for continuous parameters, and Pearson χ2 for categorical values. p < 0.05 was considered significant.

RESULTS

The cohort included 125 pregnant patients, 31 developed preeclampsia (PE) alone (13 were <34 weeks' gestation), 16 had intrauterine growth restriction (IUGR) alone (12 were <34 weeks), 42 had both IUGR and PE (22 were <34 weeks), and 15 had an iatrogenic preterm delivery (PTD; 6 were <34 weeks). Twenty-one were unaffected and delivered a healthy baby at term. Mean arterial blood pressure and proteinuria were significantly higher in PE and PE+IUGR but not in pure IUGR or PTD. In PE, IUGR, and PE+IUGR, the levels of soluble fms-like tyrosine kinase 1 (sFlt-1) and soluble endoglin (sEng) were significantly higher, while placental growth factor (PlGF) was very low compared to unaffected controls and PTD. PE, IUGR, and PE+IUGR also had a high anti-angiogenic ratio (sFlt-1/PlGF) and a low proangiogenic ratio of PlGF/(sFlt-1+Eng). Levels of inhibin A were significantly higher in pure PE across subgroups but had many extreme values, which made it a poor differentiator. Higher uterine artery Doppler pulsatility indexes were detected in PE, IUGR, and PE+IUGR, with similar resistance indexes and peaks of systolic velocity. A significantly different marker level between PE and IUGR was found using arterial stiffness that was 10 times higher in PE; concurrently with an increase of the reactive hyperemia index, both were accompanied by a slight increase in placental protein 13. Higher tumor necrosis factor alpha (TNFα) differentially identified iatrogenic very early PTD (<34 weeks).

CONCLUSION

Arterial stiffness can serve as a major marker to differentiate PE (with/without IUGR) from pure IUGR near delivery. TNFα can differentiate iatrogenic early PTD from other complications of pregnancy and term IUGR.

Planned home birth in Slovenia-Are we ready?

Nowadays, women want a more intimate and familiar atmosphere during labour, which results in increased planned home birth rates. Every woman has the autonomy to decide where she will give birth; however, it is important that she is informed of risks and advantages beforehand. Home births can be distinguished between planned and unplanned home births. Planned home births can be conducted by professional birth attendants (licensed midwives) or birth assistants (doulas, etc). The rates of Slovenian women who decided to deliver at home are increasing year by year. Researches on home births still present discordant data about home birth safety. Their findings have shown that the main advantage of home birth is a spontaneous birth without medical interventions, especially in multiparous low-risk women. The main disadvantage, however, is a higher risk for neonatal death, in particular on occurrence of complications requiring a transfer to hospital and surgical intervention. Global guidelines emphasize careful selection of candidates suitable for home birth, well-informed pregnant women, education of birth attendants, and strict formation of transfer indications.

Abuse of pregnant women in the healthcare system

Objective: The purpose of this study was to determine the incidence of abuse in healthcare system during pregnancy and its impact on pregnancy outcomes.Materials and methods: A validated screening Norvold Abuse Questionnaire for the identification of female victims of four kinds of abuse: emotional, physical, sexual, and the abuse in the healthcare system was anonymously offered to all women in the first 2 days postpartum.Results: The study group consisted of 1018 women, 6.2% of which reported experiencing abuse in healthcare system during pregnancy. Affected women had a higher incidence of preterm delivery (OR 2.4; 95% CI 1.2-4.8) and cesarean section rate (OR 2.0; 95% CI 1.1-3.6). Sexual abuse and abuse in healthcare system during childhood were associated with abuse in healthcare system during pregnancy (OR 4.4; CI 95% 1.2-16.2 and OR 6.9; CI 95% 1.3-35.4, respectively).Conclusions: Our study indicates that as many as 6.2% of pregnant women experience abusive encounters with perinatal care providers. These pregnancies eventually end more often preterm and by cesarean section. This possibly causal relationship should be further explored.

The Role of Health Services in Encouraging Disclosure of Violence Against Women

Introduction

The aim of the survey was to assess the differences in disclosure by the type of violence to better plan the role of health services in identifying and disclosing violence.

Methods

A validated, anonymous screening questionnaire (NorAQ) for the identification of female victims of violence was offered to all postpartum women at a single maternity unit over a three-month period in 2014. Response rate was 80% (1018 respondents). Chi square test was used for statistical analysis (p<0.05 significant).

Results

There are differences in disclosure by type of violence. Nearly half (41.5%) of violence by health care services was not reported, compared to 33.7% physical, 23.4% psychological, and 32.5% sexual that was reported. The percentage of violence in intimate partnership reported to health care staff is low (9.3% to 20.8%), but almost half of the violence experienced by heath care services (44%) is reported. Intimate partnership violence is more often reported to the physician than to the psychologist or social worker. Violence in health care service is reported also to nurses.

Conclusions

Disclosure enables various institutions to start with the procedures aimed at protecting victims against violence. Health workers should continuously encourage women to speak about violence rather than asking about it only once. It is also important that such inquiries are made on different levels of health care system and by different health care professions, since there are differences to whom women are willing to disclose violence.

Impact of risk factors other than prematurity on periventricular leukomalacia. A population-based matched case control study

OBJECTIVE

Periventricular leukomalacia (PVL) is a neonatal brain white matter injury associated with development of cerebral palsy, intellectual impairment, and visual disturbances. PVL is more common in premature neonates. Our objective was to examine the impact of several potential risk factors other than prematurity on the incidence of PVL.

STUDY DESIGN

A case-control study based on the Slovenian National Perinatal Information System data for the period 2002-2011. All singleton and twin pregnancies delivered at ≥22 weeks' in Slovenia during the study period were included. Cases were pregnancies with PVL in at least one neonate. For each pregnancy in the case cohort, three pregnancies matched by gestational age and plurality were selected. Chi-square test was used to examine the associations between PVL and several potential risk factors: maternal age, pre-pregnancy body-mass-index, preexisting diabetes, gestational diabetes, pregnancy after in-vitro-fertilization, severe preeclampsia, vaginal delivery, no steroid therapy prior to delivery, small for gestational age, and fetal-inflammatory-response-syndrome. P<0.05 was considered statistically significant.

RESULTS

One lakh ninety one thousand and eighty three singleton and 3377 twin pregnancies delivered at ≥22 weeks' in Slovenia during the study period. PVL was diagnosed in 86 singletons (0.045%) and 25 twins (0.74%). In all twin pregnancy cases only one twin was diagnosed with PVL. 258 singleton and 75 twin controls were matched to the 86 singleton and 25 twin cases. Of all risk factors studied, only maternal obesity and chorioamnionitis were significantly associated with PVL.

CONCLUSION

Maternal obesity and chorioamnionitis increase the risk of PVL beyond that expected solely from prematurity.

Prospective risk of stillbirth in monochorionic-diamniotic twin gestations: a population based study

OBJECTIVE

To calculate a population-based prospective risk of fetal death in monochorionic-diamniotic twins.

STUDY DESIGN

We evaluated 387 monochorionic-diamniotic twin pregnancies that were followed and delivered after 24 weeks in Slovenia during the period 1997-2007. Surveillance was not standardized. The prospective risk of fetal death was calculated as the total number of deaths after the beginning of the gestational period divided by the number of continuing pregnancies at or beyond that period.

RESULTS

Fetal death rate was 32 of 774 fetuses (4.1%; 95% confidence interval (CI), 3.0%-5.9%); the prospective risk of stillbirth per pregnancy after 33 weeks of gestation was 6.2% (95% CI, 4.2%-9.1%).

CONCLUSION

The Slovenian population-based prospective risk of fetal death in monochorionic-diamniotic pregnancies that remained undelivered after 33 weeks' gestation is higher than previously reported from hospital-based studies.
