Abstract
This study aimed to identify the risk factors for placenta accreta spectrum (PAS) in women who had at least one previous cesarean delivery and a placenta previa or low-lying. The PACCRETA prospective population-based study took place in 12 regional perinatal networks from 2013 through 2015. All women with one or more prior cesareans and a placenta previa or low lying were included. Placenta accreta spectrum (PAS) was diagnosed at delivery according to standardized clinical and histological criteria. Of the 520,114 deliveries, 396 fulfilled inclusion criteria; 108 were classified with PAS at delivery. Combining the number of prior cesareans and the placental location yielded a rate ranging from 5% for one prior cesarean combined with a posterior low-lying placenta to 63% for three or more prior cesareans combined with placenta previa. The factors independently associated with PAS disorders were BMI ≥ 30, previous uterine surgery, previous postpartum hemorrhage, a higher number of prior cesareans, and a placenta previa. Finally, in this high-risk population, the rate of PAS disorders varies greatly, not only with the number of prior cesareans but also with the exact placental location and some of the women's individual characteristics. Risk stratification is thus possible in this population.

Abstract
Abstract
Background and objectives
Previous studies showed disparities in prenatal screening for Down syndrome according to the maternal place of birth. Among the factors that might be involved in these differences, social cognition offers the concept of implicit bias (IB) used to describe the fact of having attitudes towards people or associating stereotypes with them without necessarily conscious knowledge. In line with theoretical and empirical contributions in social psychology that postulate and demonstrate the role of automatic processes in determining behavior, IBs often predict how individuals behave more accurately than conscious values. The existence of IB among health professionals has been demonstrated in emergency care or pain management. To our knowledge, no study of IB has been conducted in Europe, nor in the field of perinatal care. Thus, our objectives were to test for IBs towards African women in terms of evaluation (negative bias) and strength (positive bias) among perinatal health professionals and test whether these IBs predicted treatment recommendations toward African vs. French patients.
Methods
Through online data collection, 887 perinatal care practicians (obstetrician-gynecologists, midwives) answered a series of case vignettes depicting African vs. French patients, with one specific to a Down syndrome screening situation. Then, participants completed two Implicit Association Tests to assess valence and strength IBs toward African vs. French women.
Results
81.3% of the sample showed an implicit evaluative preference for French over African women, and 60.2% had an implicit perception of African women as stronger than French. However, decision toward Down syndrome screening were not influenced by the patient's origin nor by the healthcare professional implicit bias.
Conclusions
Perinatal practicians seem to have implicit biases toward African women, but the way they provide information regarding Down Syndrome screening is not affected.

Abstract
The incidence of maternal hemorrhage and blood transfusion has increased over time. Causes of massive hemorrhage, defined as a transfusion > 10 units of erythrocytes, include abnormal placental insertion, preeclampsia, and placental abruption. Although ratio-based transfusion has been described for managing massive hemorrhage, a goal-directed approach using laboratory or point-of-care data may lead to better outcomes. Autotransfusion, which involves the collection, washing, and filtration of maternal shed blood, avoids many of the complications associated with allogeneic blood transfusion. In this review, we provide an overview of transfusion practices related to the management of obstetric hemorrhage.

Abstract
OBJECTIVE To describe and compare the characteristics of women with placenta accreta spectrum (PAS) and their pregnancy outcomes according to the presence of placenta praevia and a prior caesarean section. DESIGN Prospective population-based study. SETTING All 176 maternity hospitals of eight French regions. POPULATION Two hundred and forty-nine women with PAS, from a source population of 520 114 deliveries. METHODS Women with PAS were classified into two risk-profile groups, with or without the high-risk combination of placenta praevia (or an anterior low-lying placenta) and at least one prior caesarean. These two groups were described and compared. MAIN OUTCOME MEASURES Population-based incidence of PAS, characteristics of women, pregnancies, deliveries and pregnancy outcomes. RESULTS The PAS population-based incidence was 4.8/10 000 (95% CI 4.2-5.4/10 000). After exclusion of women lost to follow up from the analysis, the group with placenta praevia and a prior caesarean included 115 (48%) women and the group without this combination included 127 (52%). In the group with both factors, PAS was more often suspected antenatally (77% versus 17%; P < 0.001) and more often percreta (38% versus 5%; P < 0.001). This group also had more hysterectomies (53% versus 21%, P < 0.001) and higher rates of blood product transfusions, maternal complications, preterm births and neonatal intensive care unit admissions. Sensitivity analysis showed similar results after exclusion of women who delivered vaginally. CONCLUSION More than half the cases of PAS occurred in women without the combination of placenta praevia and a prior caesarean delivery, and these women had better maternal and neonatal outcomes. We cannot completely rule out that some of the women who delivered vaginally had placental retention rather than PAS; however, we found similar results among women who delivered by caesarean. TWEETABLE ABSTRACT Half the women with PAS do not have both placenta praevia and a prior caesarean delivery, and they have better maternal outcomes.

Abstract
Pregnant women and parturients have also been concerned by the COVID-19 pandemic. However, they are not especially at risk for severe forms of the disease prone to induce prematurity but without transmission to the fœtus. Obstetrical management of parturients have changed with an extensive use of teleconsultation and a limitation of relatives in the delivery room and in the ward. The choice of the mode of delivery remains determined by obstetrical reasons, and use of regional anaesthesia remains recommended for labour and caesarean section provided there is not haemostasis disorders. The pandemic issue has not change management of fever and hypertension. The post-partum period is more impacted due to an increased risk of thromboembolic events justifying an extended use of anticoagulants. On the other hand, the use of non-steroidal anti-inflammatory drugs is restricted. The key point was cooperation between obstetricians, anaesthesiologists, intensivists and pediatrician.

Abstract
OBJECTIVES The world is currently facing an unprecedented healthcare crisis caused by the COVID-19 pandemic. The objective of these guidelines is to produce a framework to facilitate the partial and gradual resumption of intervention activity in the context of the COVID-19 pandemic. METHODS The group has endeavoured to produce a minimum number of recommendations to highlight the strengths to be retained in the 7 predefined areas: (1) protection of staff and patients; (2) benefit/risk and patient information; (3) preoperative assessment and decision on intervention; (4) modalities of the preanaesthesia consultation; (5) specificity of anaesthesia and analgesia; (6) dedicated circuits and (7) containment exit type of interventions. RESULTS The SFAR Guideline panel provides 51 statements on anaesthesia management in the context of COVID-19 pandemic. After one round of discussion and various amendments, a strong agreement was reached for 100% of the recommendations and algorithms. CONCLUSION We present suggestions for how the risk of transmission by and to anaesthetists can be minimised and how personal protective equipment policies relate to COVID-19 pandemic context.

Abstract
Abstract
Background
For a decade, pain labor management has evolved: if neuraxial analgesia remains the gold standard, non-pharmacological methods are developing. We aimed to identify individual and organizational factors associated with the use of non-pharmacological analgesia, combined or not with neuraxial analgesia.
Methods
Women who attempted vaginal delivery with labor analgesia were selected from the 13,147 participants of the 2016 National Perinatal Survey. Labor analgesia was studied as follows: neuraxial analgesia only (NA), non-pharmacological analgesia only (NPA) or neuraxial and non-pharmacological methods combined (NA+NPA). Associations between individual and organizational characteristics were studied using a multilevel multinomial logistic regression.
Results
Among the 9 231 women included, 62.4% had NA only, 6.5% had NPA only and 31.1% had NA+NPA. Both NPA and NA+NPA were associated with multiparity with antenatal classes, educational level ≥ 5 years post graduate, antenatal preference to deliver without NA, and delivery in public maternity units. The use of NPA only was positively associated with non-permanent availability of the anesthesiologist and with a high number of midwives per shift in maternity units. Contrastingly, NPA only was negatively associated with foreign nationality and oxytocin use for induction or augmentation of obstetrical labor. NA+NPA was positively associated with primiparity with antenatal classes, but negatively with inadequate prenatal care.
Conclusions
Less than 40% of parturients used non-pharmacological analgesia during labor and for the most of them as complementary methods to neuraxial analgesia. NPA and NA+NPA were associated with individual characteristics as well as characteristics of management of labor and organization of maternity units. Non-pharmacological analgesia appears to be dedicated to high educated and well-integrated women in perinatal health care system.
Key messages

Abstract
BACKGROUND Abnormally invasive placentation is the leading cause of obstetric hysterectomy and can cause poor to disastrous maternal outcomes. Most previous studies of peripartum management and maternal morbidity have included variable proportions of severe and less severe cases. OBJECTIVE The aim of this study was to compare maternal morbidity from placenta percreta and accreta. STUDY DESIGN This retrospective study at a referral center in Paris includes all women with abnormally invasive placentation from 2003 through 2017. Placenta percreta and accreta were diagnosed histologically or clinically. When placenta percreta was suspected before birth, a conservative approach leaving the placenta in situ was proposed because of the intraoperative risk of cesarean delivery. When placenta accreta was suspected, parents were offered a choice of a conservative approach or an attempt to remove the placenta, to be followed in case of failure by hysterectomy. Maternal outcomes were compared between women with placenta percreta and those with placenta accreta/increta. The primary outcome measure was a composite criterion of severe acute maternal morbidity including at least 1 of the following: hysterectomy during cesarean delivery, delayed hysterectomy, transfusion of ≥10 U of packed red blood cells, septic shock, acute kidney injury, cardiovascular failure, maternal transfer to intensive care, or death. RESULTS Of the 156 women included, 51 had placenta percreta and 105 placenta accreta. Abnormally invasive placentation was suspected antenatally nearly 4 times more frequently in the percreta than the accreta group (96.1% [49/51] vs 25.7% [27/105], P < .01). Among the 76 women with antenatally suspected abnormally invasive placentation (48.7%), the rate of antenatal decisions for conservative management was higher in the percreta than the accreta group (100% [49/49] vs 40.7% [11/27], P < .01). The composite maternal morbidity rate was significantly higher in the percreta than the accreta group (86.3% [44/51] vs 28/105 [26.7%], P < .001). A secondary analysis restricted to women with an abnormally invasive placentation diameter >6 cm showed similar results (86.0% [43/50) vs 48.7% [19/38), P < .01). The rate of hysterectomy during cesareans was significantly higher in the percreta than the accreta group (52.9% [27/51] vs 20.9% [22/105], P < .01) as was the total hysterectomy rate (43/51 [84.3%] vs 23.8% [25/105], P < .01). CONCLUSION Severe maternal morbidity is much more frequent in women with placenta percreta than with placenta accreta, despite multidisciplinary planning, management in a referral center, and better antenatal suspicion.

Abstract
Postpartum Haemorrhage (PPH) is a major cause of maternal morbidity and mortality. Treatment of acquired coagulopathy observed in severe PPH is an important part of PPH management, but is mainly based on literature in trauma patients, and data thus should be interpreted with caution. This review describes recent advances in transfusion strategy and in the use of tranexamic acid and fibrinogen concentrates in women with PPH.

Abstract
Trace metal elements (TME) can be real threats for living organisms. However, few studies dealt with TME in reservoirs in rural areas where farming practises could induce negative effects. Mae Thang reservoir (northern Thailand) has been studied for 3 years to understand the seasonal behaviour of dissolved TME: Fe, Mn, Cd, Al, Pb, V, Cr, Co, Ni, Cu, Zn, Mo, U and As and associated physicochemical parameters. In situ measurements of these parameters were done during the dry and the wet seasons as well as water samples along the water column for further analyses and TME determination by inductively coupled plasma-mass spectrometry (ICP-MS). In the dry season, the water column was characterized by a strong stratification and anoxic conditions in the hypolimnion. High rain and water input from the watershed during the wet season induced mixing of the water. All TME, except Ni, Co and Cr were less concentrated in the wet season indicating a dilution effect by water input. There was thus no important dissolved pollution coming from the watershed. The anoxic conditions in the dry season enhanced the reduction of Fe and Mn and the desorption processes. Depth, and thus oxic-anoxic conditions were the main drivers of TME in the dry season, while in the wet season, dissolution processes from parent rocks of watershed were favoured. The average concentrations of TME in the reservoir were in the limit of the international and Thai standards. Only localized values in the bottom of the reservoir for Fe and Mn were higher than the limits.

Abstract
PURPOSE Intra-articular administration of local anesthetic solution provides analgesia after arthroscopic knee surgery. Bupivacaine is considered the gold standard local anesthetic in this indication, but ropivacaine, which is less toxic than bupivacaine, can consequently be administered in higher doses, potentially increasing the duration of analgesia. We compared the analgesic effect of intra-articular injection of ropivacaine 225 mg and bupivacaine 150 mg in patients undergoing arthroscopic surgery. TYPE OF STUDY Double-blind, randomized prospective clinical study. METHODS The study included 45 patients scheduled for knee meniscus repair under arthroscopy, who were allocated randomly into 3 groups to receive, intra-articularly, 30 mL of isotonic saline, bupivacaine 0.5%, or ropivacaine 0.75% solutions at the end of surgery. Postoperatively, pain was measured using a visual analog scale (VAS) at rest and on mobilization. Propacetamol was given when patients complained of pain. RESULTS VAS scores at rest and on mobilization were higher in the saline group compared with the ropivacaine group (P = .006 and P = .01, respectively). No difference in VAS scores was documented between bupivacaine and the saline groups. The median delay between the intra-articular administration and propacetamol administration was shorter in the saline group (15 minutes; range, 15 to 120 minutes) compared with the ropivacaine group (240 minutes; range 15 to 720 minutes) but no difference was documented between the bupivacaine group (30 minutes; range, 15 to 360 minutes) and the other 2 groups. CONCLUSIONS This level I study documents that intra-articular ropivacaine 0.75% provides better analgesia than bupivacaine 0.5% after knee arthroscopic surgery. LEVEL OF EVIDENCE Level I.

Abstract
Lundberg (or B) waves, defined as repetitive changes in intracranial pressure (ICP) occurring at frequencies of 0.5 to 2 waves/min, have been attributed to cerebral blood flow fluctuations induced by central nervous system pace-makers or cerebral pressure autoregulation. We prospectively recorded and digitalized at a frequency rate of 10 Hz (AcqKnowledge software) the following parameters in 6 brain injured patients: mean arterial pressure, heart rate, ICP, mean flow velocity of the middle cerebral artery (MFVMCA) (transcranial Doppler WAKI) and left and right spectral edge frequency (SEFl, SEFr) of continuous electroencephalogram (EEG) recordings (Philips technologies). All patients were sedated using a combination of sufentanil and midazolam and mechanically ventilated. Cerebral electrical activity (oscillations of SEF at a mean frequency of 26+/-9 mHz) and MFVMCA fluctuations were found strongly correlated with the intracranial Lundberg B waves (mean frequency 23+/-7 mHz). These result support the existence of a neuropacemaker at the origin of the Lundberg B waves. The change in cerebral electrical activity, resulting from cerebral pacemakers, could increase cerebral metabolic rate of oxygen (CMRO2) and thus lead to an increase in cerebral blood flow and secondarily of ICP through a change in cerebral blood volume.
