Synbiotics in patients at risk for spontaneous preterm birth: protocol for a multi-centre, double-blind, randomised placebo-controlled trial (PRIORI).

Background: Prematurity remains one of the main causes of neonatal morbidity and mortality. Approximately two thirds of preterm births are spontaneous, i.e.

Low-dose aspirin prophylaxis to prevent hypertensive disorders of pregnancy after in vitro fertilisation: a scoping review protocol.

Introduction: Pregnancies resulting from in vitro fertilisation are associated with an increased risk of developing hypertensive disorders of pregnancy, such as preeclampsia, when compared with naturally conceived pregnancies.

Objective: The efficacy of aspirin prophylaxis to reduce the incidence of preeclampsia is well established in naturally conceived pregnancies identified as high risk for developing preeclampsia. However, the efficacy of aspirin to reduce the rate of preeclampsia for all pregnancies resulting from in vitro fertilisation remains uncertain, although in vitro fertilisation conception is a well-known risk factor for preeclampsia.

[Right aortic arch with mirror image branching : a rare cause of dysphagia].

We report the case of a 36-year-old female whose dysphagia revealed a congenital anomaly of the thoracic aorta: the right aortic arch with mirror image branching. This is a rare embryonic developmental anomaly where the aorta wraps around the right bronchus and the supra-aortic trunks emerge from the arch in the opposite order to normal. Most of the patients are asymptomatic unless there is a significant compression of mediastinal structures.

Multicentre randomised trial of screening with sFlt1/PlGF and planned delivery to prevent pre-eclampsia at term: protocol of the PE37 study.

Introduction: Pre-eclampsia affects ~5%-7% of pregnancies. Although improved obstetric care has significantly diminished its associated maternal mortality, it remains a leading cause of maternal morbidity and mortality in the world. Term pre-eclampsia accounts for 70% of all cases and a large proportion of maternal-fetal morbidity related to this condition.

Impact of Assisted Reproduction Techniques on Adverse Maternal Outcomes and on the Rate of Hospitalization in Maternal Intensive Care.

The aim of this retrospective cohort study is to evaluate the impact of assisted reproductive treatment (ART) on adverse maternal outcomes and the rate of hospitalization in maternal intensive care (MIC) in a tertiary university center in Liege, Belgium. This is a retrospective cohort study comparing two groups, 6557 patients who achieved pregnancy spontaneously and 330 patients who achieved pregnancy after ART, between January 2020 and December 2022. These patients were followed in the academic obstetrics department of Citadelle Hospital, Liège.

[Etiology of preeclampsia after assisted reproductive treatments].

About 12 percent of women require assisted reproductive technology (ART) to get pregnant as infertility concerns more and more couples. Recent studies highlight obstetrical complications after ART such as preeclampsia, gestational diabetes or placenta accrete spectrum. Pre-eclampsia is a specific pathology of the pregnancy which can lead to materno-fetal complications including prematurity and intrauterine growth restriction.

CHECGAIT: A Functional Electrical Stimulation Clinical Pathway to Reduce Foot Drop during Walking in Adult Patients with Upper Motor Neuron Lesions.

Foot drop during the swing phase of gait and at initial foot contact is a current kinematic abnormality that can occur following an upper motor neuron (UMN) lesion. Functional electrical stimulation (FES) of the common peroneal nerve through an assistive device is often used in neuro-rehabilitation to help patients regain mobility. Although there are FES-specific guideline recommendations, it remains a challenge for clinicians to appropriately select patients eligible for the daily use of FES devices, as very few health insurance systems cover its cost in Europe.

Methotrexate for CSPs.

Expectant management of a cesarean scar pregnancy (CSP) is associated with a high risk of severe maternal morbidity. Therefore, most experts recommend immediate termination after the diagnosis of a CSP. However, there is no consensus about the optimal management of a CSP in terms of efficacy, safety, and preservation of future fertility.

Definition and Criteria for Diagnosing Cesarean Scar Disorder.

Importance: Approximately 60% of women develop a uterine niche after a cesarean delivery (CD). A niche is associated with various gynecological symptoms including abnormal uterine bleeding, pain, and infertility, but there is little consensus in the literature on the distinction between the sonographic finding of a niche and the constellation of associated symptoms.

Objective: To achieve consensus on defining the clinical condition that constitutes a symptomatic uterine niche and agree upon diagnostic criteria and uniform nomenclature for this condition.

[Diagnosis and management of a foetus with congenital high airway obstruction syndrome (CHAOS)].

Congenital high airway obstruction syndrome is a rare malformation whose prognosis is very poor resulting in foetal or perinatal death if no perinatal intervention is performed. However, ultrasound and magnetic resonance enable an accurate prenatal diagnosis and optimal choice of interventional foetal medicine techniques (transtracheal puncture, fetoscopy). These approaches reduce foetal side effects related to the pathological process, and avoid the mother ex utero intrapartal treatment and its deleterious effects.

Modified Delphi study of ultrasound signs associated with placenta accreta spectrum.

Objective: To determine, by expert consensus through a modified Delphi process, the role of standardized and new ultrasound signs in the prenatal evaluation of patients at high risk of placenta accreta spectrum (PAS).

Methods: A systematic review of articles providing information on ultrasound imaging signs or markers associated with PAS was performed before the development of questionnaires for the first round of the Delphi process. Only peer-reviewed original research studies in the English language describing one or more new ultrasound sign(s) for the prenatal evaluation of PAS were included.

Classification of Stiff-Knee Gait Kinematic Severity after Stroke Using Retrospective k-Means Clustering Algorithm.

Nowadays, a classification system for unilateral stiff-knee gait (SKG) kinematic severity in hemiparetic adult patients after stroke does not exist. However, such classification would be useful to the clinicians. We proposed the use of the k-means method in order to define unilateral SKG severity clusters in hemiparetic adults after stroke.

Investigation of discrepancies obtained during 15 years of non-invasive fetal RHD genotyping in apparent serologic RhD-negative pregnant women.

Objectives: In some European countries, non-invasive fetal RHD genotyping is the first step of anti-D allo-immunized pregnant women management but presence of RHD variant alleles may interfere with the results accuracy. We developed an algorithm allowing solving discordant results (due to the presence of RHD variant) in fetal RHD genotyping assay.

Method: This study gathered the results of fetal RHD genotyping performed between 2006 and 2020 in the Medicine Laboratory of CHR Liège.

[Uterine rupture in a patient with a cesarean scar pregnancy].

Caesarean scar pregnancy is a rare form of ectopic pregnancy, but it is increasingly common due to the increasing number of caesarean sections and advances in medical imaging. There are two types of cesarean scar pregnancy depending on the depth of the implantation : endogenous type I and exogenous type II. In the case of a pregnancy resulting from a type II caesarean scar, the main complication is uterine rupture, which could be life-threatening for the patient.

Metabolic Energy Expenditure and Accelerometer-Determined Physical Activity Levels in Post-Stroke Hemiparetic Patients.

Background: Assessment of metabolic energy expenditure in post-stroke patients using accelerometers is clinically important. However, understanding of the best placement of accelerometers on the body and methods for calculating activity counts are limited.

Methods: Thirty hemiparetic post-stroke patients participated in this cross-sectional study.

First-line noninvasive management of cytomegalovirus primary infection in pregnancy.

Objectives: To introduce a first-line noninvasive antenatal management of maternal cytomegalovirus (CMV) primary infection based on ultrasound (US) and magnetic resonance imaging (MRI). Amniocentesis (AC) is used as a second-line tool in cases of abnormalities compatible with fetal CMV infection on US and/or MRI screening.

Methods: Between January 2011 and October 2018, pregnant women referred with a CMV primary infection on antibody screening were followed up by monthly US scans and a brain MRI at approximately 32 weeks.

Enhancing the value of the sFlt-1/PlGF ratio for the prediction of preeclampsia: Cost analysis from the Belgian healthcare payers' perspective.

Objective: To evaluate the economic impact of introducing the soluble fms-like tyrosine kinase (sFlt-1) to placental growth factor (PlGF) ratio test into clinical practice in Belgium for the prediction of preeclampsia (PE).

Study Design: We developed a one-year time-horizon decision tree model to evaluate the short-term costs associated with the introduction of the sFlt-1/PlGF test for guiding the management of women with suspected PE from the Belgian public healthcare payers' perspective. The model estimated the costs associated with the diagnosis and management of PE in pregnant women managed in either a test scenario, in which the sFlt-1/PlGF test is used in addition to current clinical practice, or a no test scenario, in which clinical decisions are based on current practice alone.

The relation between maternal obesity and placenta accreta spectrum: A multinational database study.

Introduction: It has been suggested that women with obesity have increased risk of developing placenta accreta spectrum (PAS). It is unclear if this is independent of the increased risk of cesarean delivery seen with obesity itself. The aim of this study was to explore the association between maternal obesity and PAS, particularly severe PAS (percreta).

When a rare condition creates a scientific society: The history of the International Society for Placenta Accreta Spectrum (IS-PAS).

Almost 10 years ago, clinicians at multiple locations all over Europe observed an increased number of antenatally undiagnosed cases of placenta accreta spectrum (PAS) resulting in significant morbidity and the occasional maternal death. Even with an improvement in antenatal imaging, the management of severe PAS remains challenging. One solution to improve understanding in rare but potentially lethal conditions is international collaboration.

Gestational Age-Specific Reference Ranges for the sFlt-1/PlGF Immunoassay Ratio in Twin Pregnancies.

Objective: Establish reference ranges for the Elecsys® soluble fms-like tyrosine kinase-1 (sFlt-1)/placental growth factor (PlGF) immunoassay ratio in twin pregnancies.

Methods: Data analyzed were from 3 prospective studies: Prediction of Short-Term Outcome in Pregnant Women with Suspected Preeclampsia (PE) (PROGNOSIS), Study of Early-onset PE in Spain (STEPS), and a multicenter case-control study. Median, 5th, and 95th percentiles for sFlt-1, PlGF, and the sFlt-1/PlGF ratios were determined for normal twin pregnancies for 7 gestational windows and compared with the previous data for singleton pregnancies.

A multicenter observational survey of management strategies in 442 pregnancies with suspected placenta accreta spectrum.

Introduction: Management options for women with placenta accreta spectrum (PAS) comprise termination of pregnancy before the viable gestational age, leaving the placenta in situ for subsequent reabsorption of the placenta or delayed hysterectomy, manual removal of placenta after vaginal delivery or during cesarean section, focal resection of the affected uterine wall, and peripartum hysterectomy. The aim of this observational study was to describe actual clinical management and outcomes in PAS in a large international cohort.

Material And Methods: Data from women in 15 referral centers of the International Society of PAS (IS-PAS) were analyzed and correlated with the clinical classification of the IS-PAS: From Grade 1 (no PAS) to Grade 6 (invasion into pelvic organs other than the bladder).

Benefits of nonlinear analysis indices of walking stride interval in the evaluation of neurodegenerative diseases.

Indices characterising the long-range temporal structure of walking stride interval (SI) variability such as Hurst exponent (H) and fractal dimension (D) may be used in addition to indices measuring the amount of variability like the coefficient of variation (CV). We assess the added value of the former indices in a clinical neurological context. Our aim is to demonstrate that they provide a clinical significance in aging and in frequent neurodegenerative diseases such as Parkinson's disease, Huntington, and amyotrophic lateral sclerosis.

[Twin pregnancy and polymalformative syndrome by Enterovirus].

Prenatal diagnosed congenital infection by Enterovirus is rarely described in the literature. A few casereports describe severe abnormalities observed by ultrasound that have led to spontaneous intrauterine demise or early death of the newborn. We report the case of a dichorionic diamniotic twin pregnancy.
