RESUMO

BACKGROUND: Amniotic banding is a rare condition that can lead to structural limb anomalies, fetal distress and adverse obstetric outcomes. The main hypothesis for its etiology is a rupture of the amniotic membrane in early pregnancy, with the formation of tightly entangling strands around the fetus. These strands can constrict, incise, and subsequently amputate limb parts, the neck or head. More rarely, the amniotic banding can affect the umbilical cord, leading to fetal distress or potential intra-uterine fetal demise. OBJECTIVE: We present a unique case of a 26-week pregnant woman who attended a polyclinical consultation due to reduced fetal movements with concerning cardiotocography (CTG) findings. A review of the literature about amniotic banding of the umbilical cord was conducted as well, identifying diagnostic and interventional options for the obstetrician's practice. STUDY DESIGN: This is a case report, alongside a review of the literature. RESULTS: The CTG indicated fetal distress, prompting an emergency caesarean section (C-section). Upon delivery, the neonate exhibited signs of amniotic band sequence, with distal phalangeal defects on the right hand and severe constriction of the umbilical cord caused by amniotic strands, the latter precipitating fetal hypoxia. Direct ultrasound diagnosis remains a challenge in the absence of limb amputation, yet indirect signs such as distal limb or umbilical doppler flow abnormalities and distal limb edema may be suggestive of amniotic banding. MRI is proposed as an adjuvant diagnostic tool yet does not present a higher detection rate compared to ultrasound. Fetoscopic surgery to perform lysis of the amniotic strands with favorable outcome has been described in literature. CONCLUSION: This case presents the first reported survival of an extremely preterm fetus in hypoxic distress as a cause of amniotic banding of the umbilical cord, with a rare degree of incidental timing. Ultrasound diagnosis remains the gold standard. Obstetrical vigilance is warranted, with fetal rescue proven to be feasible.

RESUMO

BACKGROUND: The introduction of assisted reproductive technology and the trend of increasing maternal age at conception have contributed to a significant rise in the incidence of multiple pregnancies. Multiple pregnancies bear several inherent risks for both mother and child. These risks increase with plurality and type of chorionicity. Multifetal pregnancy reduction is the selective abortion of ≥1 fetuses to improve the outcome of the remaining fetus(es) by decreasing the risk of premature birth and other complications. OBJECTIVE: This study aimed to compare birth outcomes of trichorionic triplets reduced to twins with those of trichorionic triplets and primary dichorionic twins. The added value of this study is the comparison with an additional control group, namely primary dichorionic twins. STUDY DESIGN: This was a retrospective cohort study. Data from January 1990 to November 2016 were collected from the East Flanders Prospective Twin Survey, one of the largest European multiple birth registries. A total of 85 trichorionic triplet pregnancies (170 neonates) undergoing multifetal pregnancy reduction to twins were compared with 5093 primary dichorionic twin pregnancies (10,186 neonates) and 104 expectantly managed trichorionic triplet pregnancies (309 neonates). The assessed outcomes were gestational age at delivery, birthweight, and small for gestational age. RESULTS: Pregnancy reduction from triplets to twins was associated with higher birthweight (+365.44 g; 95% confidence interval, 222.75-508.14 g; P<.0001) and higher gestational age (1.7 weeks; 95% confidence interval, 0.93-2.46; P<.0001) compared with ongoing trichorionic triplets after adjustment for sex, parity, method of conception, birth year, and maternal age. A trend toward lower risk of small for gestational age was observed. Reduced triplets had, on average, lower birthweight (-263.12 g; 95% confidence interval, -371.80 to -154.44 g; P<.0001) and lower gestational age (-1.13 weeks; 95% confidence interval, -1.70 to -0.56; P=.0001) compared with primary twins. No statistically significant difference was observed between primary twins and reduced triplets that reached 32 weeks of gestation. CONCLUSION: Multifetal pregnancy reduction from trichorionic triplets to twins significantly improved birth outcomes. This suggests that multifetal pregnancy reduction of trichorionic triplets to twins is medically justifiable. However, the birth outcomes of primary twins before 32 weeks of gestation are still better than those of reduced triplets. The process of multifetal pregnancy reduction includes at least 1 fetal death by definition, and thus prevention of higher-order pregnancies is preferable.

RESUMO

BACKGROUND: Sexual assault (SA) can induce a negative impact on victims' mental health. Specialised SA services generally offer medical care and a forensic examination to SA victims. However, there is a large variation in how these services provide mental health support. OBJECTIVE: This study aims to assess mental health problems of SA victims attending the Belgian Sexual Assault Care Centres (SACCs) and identify predictors for victims' use of support from in-house psychologists. METHOD: Health records of victims ≥ 16 years who presented within one week post-SA to one of the three Belgian SACCs between 25 October 2017 and 31 October 2019 were reviewed. An AIC-based stepwise backward binary logistic regression was used to analyse the association between victim, assault, service use and mental health characteristics and follow-up by a SACC-psychologist. RESULTS: Of the 555 victims, more than half had a history of mental health problems. Of those assessed, over 70% showed symptoms of posttraumatic stress disorder (PTSD), depression and/or anxiety disorder. One in two victims consulted a SACC-psychologist. Victims with a mental health history (OR 1.46, p = .04), victims accompanied by a support person during acute care (OR 1.51, p = .04), and victims who were assaulted by an acquaintance in comparison to those assaulted by a stranger (OR 1.60, p = .039) were more likely to attend their appointment with the SACC-psychologist. CONCLUSION: The study reaffirms the high mental health burden among victims attending specialised SA services, stressing the need to provide effective mental health interventions at these services and improve their longer-term use by victims. Prescheduling of appointments with an in-house psychologist in combination with phone reminders may improve the uptake of such services. Health care providers must be vigilant about potential barriers faced by victims without a mental health history or social support in attending appointments with mental health professionals.


The mental health burden is high among victims attending Belgian Sexual Assault Care Centres.Half of the victims use the support of an in-house psychologist. Victims with a history of mental health problems, those accompanied by a support person during acute care, and those assaulted by an acquaintance in comparison to those assaulted by a stranger, are more likely to use this support.Effective mental health support should be recognised as an integral and essential part of care for SA victims. Uptake and longer-term engagement with this mental health support should be improved for those victims diagnosed with PTSD.

RESUMO

Few victims of sexual assault (SA) report to the police. Research on the role of support persons in victims' reporting is sparse. We address this gap by examining the association of victim, assailant, victimization incident, and support characteristics with reporting rates among victims attending sexual assault care centers (SACCs). Logistic regression results show that type of SA, delay between SA and presentation at SACC, and presence of an informal support person at SACC and SACC site are significantly associated with police reporting. These findings reveal the importance of targeting victims' support persons to alter reporting behavior among SA victims.

RESUMO

BACKGROUND: Stillbirth has been recognized as a possible complication of a SARS-CoV-2 infection during pregnancy, probably due to destructive placental lesions (SARS-CoV-2 placentitis). The aim of this work is to analyse stillbirth and late miscarriage cases in unvaccinated pregnant women infected with SARS-CoV-2 during the first two waves (wild-type period) in Belgium. METHODS: Stillbirths and late miscarriages in our prospective observational nationwide registry of SARS-CoV-2 infected pregnant women (n = 982) were classified by three authors using a modified WHO-UMC classification system for standardized case causality assessment. RESULTS: Our cohort included 982 hospitalised pregnant women infected with SARS-CoV-2, with 23 fetal demises (10 late miscarriages from 12 to 22 weeks of gestational age and 13 stillbirths). The stillbirth rate was 9.5‰ for singleton pregnancies and 83.3‰ for multiple pregnancies, which seems higher than for the background population (respectively 5.6‰ and 13.8‰). The agreement between assessors about the causal relationship with SARS-Cov-2 infection was fair (global weighted kappa value of 0.66). Among these demises, 17.4% (4/23) were "certainly" attributable to SARS-CoV-2 infection, 13.0% (3/23) "probably" and 30.4% (7/23) "possibly". Better agreement in the rating was noticed when pathological examination of the placenta and identification of the virus were available, underlining the importance of a thorough investigation in case of intra-uterine fetal demise. CONCLUSIONS: SARS-CoV-2 causality assessment of late miscarriage and stillbirth cases in our Belgian nationwide case series has shown that half of the fetal losses could be attributable to SARS-CoV-2. We must consider in future epidemic emergencies to rigorously investigate cases of intra-uterine fetal demise and to store placental tissue and other material for future analyses.

RESUMO

OBJECTIVE: Congenital malformations are frequently diagnosed prenatally even at a viable stage. No adequate registration of incidence and characteristics of late termination of pregnancy (TOP) or abortion for medical reasons exists in Flanders. METHODS: Nationwide mortality follow-back survey sent to physicians signing death certificates of all stillbirths for 22 weeks gestation onward (September 2016-December 2017) in Flanders, Belgium. Questions measured whether late TOP preceded stillbirth, and which clinical and sociodemographic characteristics were indicated. Questionnaire data were linked with sociodemographic information from death certificates. RESULTS: Response rate was 56% (203/366). 38% of stillbirths (77/203) concerned late TOP. In 88.3% of late TOPs, physicians classified congenital anomalies of the foetus as serious or very serious (incompatibility with life outside the womb or severe neurological or physical impairment). In 26% of cases, late TOP was first suggested by the physician rather than spontaneously requested by parents (73%). 88% of late TOPs were discussed in open team meetings. CONCLUSIONS: 2/5 stillbirths were preceded by late TOP, indicating severe underreportation by existing registrations and a dire need for adequate registration methods. Although late TOP was most often explicitly requested by parents, in » cases termination was suggested first by physicians. Parents are sometimes hesitant to bring up late TOP themselves, indicating that TOP should always be counselled as an equivalent option.

RESUMO

OBJECTIVE: Analysis of atypical cases of uterine rupture, namely, uterine rupture occurring in unscarred, preterm or prelabour uteri. DESIGN: Descriptive multi-country population-based study. SETTING: Ten high-income countries within the International Network of Obstetric Survey Systems. POPULATION: Women with unscarred, preterm or prelabour ruptured uteri. METHODS: We merged prospectively collected individual patient data in ten population-based studies of women with complete uterine rupture. In this analysis, we focused on women with uterine rupture of unscarred, preterm or prelabour ruptured uteri. MAIN OUTCOME MEASURES: Incidence, women's characteristics, presentation and maternal and perinatal outcome. RESULTS: We identified 357 atypical uterine ruptures in 3 064 923 women giving birth. Estimated incidence was 0.2 per 10 000 women (95% CI 0.2-0.3) in the unscarred uteri, 0.5 (95% CI 0.5-0.6) in the preterm uteri, 0.7 (95% CI 0.6-0.8) in the prelabour uteri, and 0.5 (95% CI 0.4-0.5) in the group with no previous caesarean. Atypical uterine rupture resulted in peripartum hysterectomy in 66 women (18.5%, 95% CI 14.3-23.5%), three maternal deaths (0.84%, 95% CI 0.17-2.5%) and perinatal death in 62 infants (19.7%, 95% CI 15.1-25.3%). CONCLUSIONS: Uterine rupture in preterm, prelabour or unscarred uteri are extremely uncommon but were associated with severe maternal and perinatal outcome. We found a mix of risk factors in unscarred uteri, most preterm uterine ruptures occurred in caesarean-scarred uteri and most prelabour uterine ruptures in 'otherwise' scarred uteri. This study may increase awareness among clinicians and raise suspicion of the possibility of uterine rupture under these less expected conditions.

RESUMO

When a severe diagnosis is made before or after birth, perinatal palliative care (PPC) can be provided to support the infant, parents and involved healthcare providers. An integrative and systematic overview of effectiveness and working components of existing PPC programs was needed. An integrative search was conducted in MEDLINE, Embase, CENTRAL, CINAHL, PsycInfo and Web of Science. Study designs examining the effect of PPC compared to regular care, and (empirical) articles describing the components of care included in existing PPC initiatives were included. Three independent authors reviewed titles, abstracts and full texts against eligibility criteria. PRISMA guidelines were followed; 21.893 records were identified; 69 publications met inclusion criteria. Twelve publications (17.4%) discussed the effect of a PPC program. Other publications concerned the description of PPC programs, most often by means of a program description (22/69; 31.9%), guidelines (14/769; 20.3%) or case study (10/69; 14.5%). Outcome measures envisioned four main target categories: care coordination, parents and family members, care for the fetus/neonate and healthcare providers. No trials exist to date. Analysis of working components revealed components related to changes directed to the policy of the hospital wards and components involving actual care being provided within the PPC program, directed to the fetus or infant, the family, involved healthcare providers or external actors. PPC is a growing research field where evidence consists mainly of descriptive studies and guidelines. The extensive list of possible PPC components can serve as a checklist for developing future initiatives worldwide. PPC includes several important actors: the fetus/infant and their family and included healthcare providers on both maternity and neonatal wards. This leads to a large variety of possible care components. However, while some studies show proof of concept, an evidence base to determine which components are actually effective is lacking.

RESUMO

Administration of antenatal corticosteroids (ACS) for accelerating foetal lung maturation in threatened preterm birth is one of the cornerstones of prevention of neonatal mortality and morbidity. To identify the optimal timing of ACS administration, most studies have compared subgroups based on treatment-to-delivery intervals. Such subgroup analysis of the first placebo-controlled randomised controlled trial indicated that a one to seven day interval between ACS administration and birth resulted in the lowest rates of neonatal respiratory distress syndrome. This efficacy window was largely confirmed by a series of subgroup analyses of subsequent trials and observational studies and strongly influenced obstetric management. However, these subgroup analyses suffer from a methodological flaw that often seems to be overlooked and potentially has important consequences for drawing valid conclusions. In this commentary, we point out that studies comparing treatment outcomes between subgroups that are retrospectively identified at birth (i.e. after randomisation) may not only be plagued by post-randomisation confounding bias but, more importantly, may not adequately inform decision making before birth, when the projected duration of the interval is still unknown. We suggest two more formal interpretations of these subgroup analyses, using a counterfactual framework for causal inference, and demonstrate that each of these interpretations can be linked to a different hypothetical trial. However, given the infeasibility of these trials, we argue that none of these rescue interpretations are helpful for clinical decision making. As a result, guidelines based on these subgroup analyses may have led to suboptimal clinical practice. As an alternative to these flawed subgroup analyses, we suggest a more principled approach that clearly formulates the question about optimal timing of ACS treatment in terms of the protocol of a future randomised study. Even if this 'target trial' would never be conducted, its protocol may still provide important guidance to avoid repeating common design flaws when conducting observational 'real world' studies using statistical methods for causal inference.

RESUMO

OBJECTIVES: Coronavirus disease (COVID-19) and its mitigation measures have been associated with changes in preterm birth (PTB) incidences. The objective of this paper is to summarize and comment on the literature on COVID-19 and PTB and to compare PTB incidence between 2019 (pre-COVID-19) and 2020 (COVID-19) in three Belgian tertiary care hospitals. METHODS: A non-systematic review on COVID-19 and PTB was performed, and literature was summarized in a table. Preterm birth rates at Ghent University Hospital, Ziekenhuis Oost-Limburg, and University Hospital Leuven in 2019 and 2020 were compared. Chi-square and Fisher's exact tests were used to compare PTB rates between 2019 and 2020, and Kaplan Meier survival analysis was used to compare pregnancy duration. The mean outcome measure was PTB incidence in 2020 (COVID-19) compared with PTB incidence in 2019 (pre-COVID-19). RESULTS: Some (parts of) countries report decreases in PTB rates, others report no differences in incidence, and a minority of countries report an increased incidence of PTB. Almost all studies only consider live-births. In three tertiary care hospitals in Flanders, there were no differences in PTB rates before and during the COVID-19 pandemic. CONCLUSION: The impact of the (mitigation measures during the) COVID-19 pandemic on PTB incidence is unclear and difficult to explore. To enable a correct interpretation, all conceptions before and during the pandemic should be taken into consideration, as well as all births, still or alive.

RESUMO

BACKGROUND: Sexual violence (SV) literature on applicants for international protection (AIPs) shows that they are at high risk of victimization. The study objectives are to provide an exploratory overview of the occurrence of SV in AIPs in Belgium and their help-seeking behavior (HSB). This overview is crucial to develop prevention strategies and care paths focusing on providing adequate care to AIP SV victims in Belgium. METHODS: Quantitative data from structured interviews with AIPs (n = 62) triangulated with qualitative data from in-depth interviews with AIP SV victims (n = 11) served to explore the nature and impact of SV in AIPs in Belgium and their HSB. RESULTS: A total of 83.9% of respondents have experienced SV. A total of 61.3% were victimized within the past year. Victimization seems more gender-balanced than in the general population. AIPs link SV to their legal status and their associated vulnerable situation. HSB upon SV was very limited in this sample. Help-seeking barriers interfering with the decision-making process to consult (in)formal resources were identified. CONCLUSIONS: AIPs in Belgium are at high risk of SV. Despite the impact of SV on AIPs' lives, HSB upon SV is rare. The provision of age-appropriate sexual education and development of policies that will reduce help-seeking barriers is needed.

RESUMO

BACKGROUND: Previous studies report vast mental health problems in sexual minority people. Representative national proportion estimates on self-identifying LGB+ persons are missing in Belgium. Lacking data collection regarding sexual orientation in either census or governmental survey data limits our understanding of the true population sizes of different sexual orientation groups and their respective health outcomes. This study assessed the proportion of LGB+ and heterosexual persons in Belgium, LGB+ persons' self-identification as sexual minority, mental health, and experienced minority stress. METHOD: A representative sample of 4632 individuals drawn from the Belgian National Register completed measures of sexual orientation, subjective minority status, and its importance for their identity as well as a range of mental-health measures. RESULTS: LGB+ participants made up 10.02% of the total sample and 52.59% of LGB+ participants self-identified as sexual minority. Most sexual minority participants considered sexual minority characteristics important for their identity. LGB+ persons reported significantly worse mental health than heterosexual persons. Sexual minority participants did not report high levels of minority stress, but those who considered minority characteristics key for their identity reported higher levels of minority stress. LGB+ participants who did not identify as minority reported fewer persons they trust. CONCLUSIONS: The proportion of persons who identified as LGB+ was twice as large as the proportion of persons who identified as a minority based on their sexual orientation. LGB+ persons show poorer mental health compared to heterosexual persons. This difference was unrelated to minority stress, sociodemographic differences, minority identification, or the importance attached to minority characteristics.

RESUMO

To objective of this study was to compare neonatal magnesemia in the first 15 days of neonatal life between three groups: a control group not exposed to MgSO4, a neuroprotection group, and an eclampsia prevention group, and to explore its associations with child outcomes. A retrospective single-centre cohort study was performed in a tertiary care setting. Infants admitted at the neonatal intensive care unit born between 24 and 32 weeks' gestation, regardless of etiology of preterm birth, were included. The mean outcome measure was neonatal magnesemia (mmol/L). Linear mixed regression of neonatal magnesemia on exposure group and day of life was done. Generalised estimating equation models of child outcomes on neonatal magnesemia according to exposure group and day of life were made. The analyses showed that in neonatal magnesemia is significantly higher in the preeclampsia group compared to the control and neuroprotection groups. On the day of birth, this is irrespective of maternal magnesemia (preeclampsia vs control groups), and the maternal total dose or duration of MgSO4 administration (preeclampsia vs neuroprotection group). No differences were found in short-term composite outcome between the three groups. CONCLUSION: We found mean differences in neonatal magnesemia between children not exposed to MgSO4 antenatally, children exposed for fetal neuroprotection, and children exposed for maternal eclampsia prevention. A 4-g loading and 1-g/h maintenance doses, for fetal neuroprotection and eclampsia prevention, appear to be safe on the short term for the neonate. WHAT IS KNOWN: • Magnesium sulphate is a valuable medicine in obstetrics. The main indications are prevention of eclampsia and fetal neuroprotection. The most used dosage is a 4- or 6-g loading dose and a 1- or 2-g per h maintenance dose. It reduces neuromotor disabilities in extreme-to-moderate preterm born children. WHAT IS NEW: • Maternal concentrations are supraphysiological and the maternal total dose can be high. Concentrations in neonates appear to remain in safe ranges. A dosage of 4-g loading and 1 g/h seems safe for the preterm neonate on the short term.

RESUMO

BACKGROUND: Some (minority) groups (MGs) are more vulnerable to sexual violence (SV) exposure than others. Othering-based stress (OBS) may mediate the relationship between minority identification and SV. This study aims to assess the prevalence of SV in different MGs to explore the relationship between minority identification and SV, to investigate whether belonging to multiple MGs moderates this relationship, and to explore OBS SV moderation for different MGs. METHOD: Through an online survey administered to a nationally representative sample in Belgium, data was collected from 4632 persons, of whom 21.01% self-identified as belonging to a MG (SI-Minority). SV prevalence was measured using behaviorally specific questions based on the WHO definition of SV. SI-Minority participants received an additional scale on OBS. RESULTS: SI-Minority participants reported more SV victimization compared to the non-minorities. However, this increased risk was not moderated by minority identification but linked to the socio-demographic SV risk markers common to minority individuals. Multiple-minority participants were found more at risk of SV compared to single-minority respondents. Lesbian, gay, bisexual, pan-/omnisexual, asexual, and other non-heterosexual (LGB+) participants were found more at risk than heterosexual participants. OBS was found to be significantly correlated to SV in sexual and gender minorities and in cultural minorities. CONCLUSIONS: This study contributes to our understanding of the relationship between minority identification, OBS, and SV. Studying both specific and common SV vulnerabilities and outcomes within specific societal subgroups and the general population may inform policy makers when allocating resources to those interventions with the largest societal impact.

RESUMO

PURPOSE: In this correspondence, we highlight general and domain-specific caveats in the development and validation of prediction models. METHODS: Development and use of the "QUiPP" application, a tool for preterm birth prediction which is supported by the United Kingdom National Health Service, is scrutinised and commented on. RESULTS: We highlight and elaborate ten points which may be perceived to be unclear or potentially misleading. CONCLUSION: While the QUiPP application has high potential, it lacks transparency (on certain aspects related to model development) and proper validation. This precludes transportability to settings with other treatment policies and to other countries where the app has been made publicly available.

RESUMO

PURPOSE: To critically analyse the literature on the antenatal corticosteroids (ACS)-to-birth interval from a causal point of view and to present a solution to the problem of bias caused by post hoc analysis. METHODS: Due to the post hoc nature of the ACS-to-birth interval, a randomised controlled trial (RCT) of ACS versus placebo is not able to examine the importance of the interval. When an RCT is not feasible, for whatsoever reason, a target trial can be set up and an attempt can be made to answer the causal question of interest using observational data. An attempt was made to set up a target trial which could enable to examine the causal effect of the ACS-to-birth interval on neonatal outcomes. An analysis of current literature on the ACS-to-birth interval was done. RESULTS: The majority of studies aimed to examine the causal effect of the interval, but their study design only permitted to find associations between the interval and neonatal outcomes. Barriers for setting up a target trial are highlighted.
