Abstract
BACKGROUND The standard treatment for gestational choriocarcinoma is chemotherapy. OBJECTIVE To describe the risk of recurrence with expectant management of gestational choriocarcinoma that has reached a normal human chorionic gonadotropin level after tumor removal without adjuvant chemotherapy. METHODS A retrospective multicenter international cohort study was conducted from 1981 to 2017 involving 11 gestational trophoblastic disease reference centers with patient's follow-up extended until 2023. Clinical and biological data of included patients were extracted from each center's database. The inclusion criteria were i) histological diagnosis of gestational choriocarcinoma in any kind of placental tissue retrieved, ii) spontaneous normalization of human chorionic gonadotropin level following choriocarcinoma retrieval, iii) patient did not receive any oncological treatment for the choriocarcinoma, iv) and at least 6 months of follow-up after the first human chorionic gonadotropin level normalization. RESULTS Among 80 patients with retrieved gestational choriocarcinoma and whose human chorionic gonadotropin level normalized without any other oncological therapy, none had a recurrence of choriocarcinoma after a median follow-up of 50 months. The median interval between choriocarcinoma excision and human chorionic gonadotropin level normalization was 48 days. The International Federation of Gynecology and Obstetrics/World Health Organization risk score was ≤6 in 93.7% of the cases. CONCLUSIONS This multicenter international study reports that selected patients with gestational choriocarcinoma managed in gestational trophoblastic disease reference centers did not experience any relapse when the initial tumor evacuation is followed by human chorionic gonadotropin level normalization without any additional treatment. Expectant management may be a safe approach for highly selected patients.

Abstract
Buerger's disease (BD), also known as thromboangiitis obliterans, is a non-atherosclerotic inflammatory disorder of unknown aetiology that affects small-sized and medium-sized vessels of the extremities. It is usually observed in middle-aged adults, especially those who smoke or use tobacco products. This condition is more frequently observed in men, although recent findings indicate an increasing prevalence among women, potentially due to increased cigarette use. The association between pregnancy and BD is rare, with only a few published cases. Previous reports have indicated that BD may worsen during gestation due to the characteristic hypercoagulable state of pregnancy. In addition, it seems to be associated with intrauterine growth restriction secondary to infarction of placental vessels. Careful obstetric management of maternal and fetal status is mandatory in pregnancies complicated with BD. We report a successful case of a pregnancy in a patient with BD treated with low-molecular-weight heparin.

Abstract
INTRODUCTION During pregnancy, the maternal immune system is challenged to tolerate a semi-allogenic fetus. A proinflammatory profile has been linked to adverse pregnancy outcomes and poor placental development. In this study, the authors evaluated the number of circulating Tregs and Th17 cells in a group of patients diagnosed with preeclampsia(PE) and fetal growth restriction(FGR). METHODS Prospective longitudinal observational study where peripheral blood lymphocyte subsets were analyzed in a cohort of pregnant patients with PE, FGR, and a control group of healthy pregnant women. RESULTS The diagnosis of PE was associated with a significative higher number of circulating Th17 cells and a significative relative reduction in the Treg cell count. This proinflammatory profile was also expressed in the evolution of the Th17/ CD4+CD25highFOXP3+ Treg ratio. In the FGR group, the Th17 cell count was significantly higher during the third trimester of pregnancy. This proinflammatory profile was also expressed in the evolution of the Th17/ CD4+CD25highFOXP3+ Treg ratio. When we compare the immunological profiles of patients with PE and FGR we observed a higher number of proinflammatory Th17 cells and a significative lower number of Treg cells in PE patients. This is particularly expressed in the differences found between the Th17/ CD4+CD25highFOXP3+ Treg ratios of these two groups. Discussion/Conclusion Our data showed a that a proinflammatory profile and a relative excess of Th17 cells was associated with the diagnosis of PE and FGR. A more exuberant systemic proinflammatory profile present in the PE patients is absent in patients with FGR without preeclampsia.

Abstract
Preeclampsia (PE) was first reported thousands of years ago, yet there is still a shortage of biomarkers to determine the severity and type of PE. The importance of the expanded endocannabinoid system, or endocannabinoidome (eCBome), has emerged recently in placental physiology and pathology, though the potential alterations of the eCBome in PE have not been fully explored. Analysis by qRT-PCR using placental samples of normotensive and PE women demonstrate for the first time the presence of ABHD4, GDE1, and DAGLβ in both normotensive and PE placental tissues. Interestingly, NAPE-PLD, FAAH-1, DAGLα, MAGL, and ABHD6 mRNA levels were increased in the placental tissues of PE patients. Quantification in plasma and placental tissues showed a decrease for anandamide (AEA), N-oleoylethanolamine (OEA), and N-docosahexaenoylethanolamine (DHEA) in the placenta, accompanied only by a decrease in plasma levels of AEA. In addition, a strong negative correlation was obtained between OEA and the biomarker of PE, soluble fms-like tyrosine kinase-1. Given the inflammatory nature of PE and the anti-inflammatory role of OEA and DHEA, the decrease in the local levels of these mediators may underlie the inflammatory component of this pathology. Additionally, lower AEA levels in both placenta and plasma may contribute to the atypical alterations of the spiral arteries in PE due to the vasorelaxation effects of AEA. These results add new information to the role of the eCBome members in placental development, while also pointing to a potential role as biomarkers of PE.

Abstract
Objective: Identify lung sequelae of COVID-19 through radiological and pulmonary function assessment. Design: Prospective, longitudinal, cohort study from March 2020 to March 2021. Setting: Intensive Care Units (ICU) in a tertiary hospital in Portugal. Patients: 254 patients with COVID-19 admitted to ICU due to respiratory illness. Interventions: A chest computed tomography (CT) scan and pulmonary function tests (PFT) were performed at 3 to 6 months. Main variables of interest: CT-scan; PFT; decreased diffusion capacity of carbon monoxide (DLCO). Results: All CT scans revealed improvement in the follow-up, with 72% of patients still showing abnormalities, 58% with ground glass opacities and 62% with evidence of fibrosis. PFT had abnormalities in 94 patients (46%): thirteen patients (7%) had an obstructive pattern, 35 (18%) had a restrictive pattern, and 58 (30%) had decreased DLCO. There was a statistically significant association between abnormalities in the follow-up CT scan and older age, more extended hospital and ICU stay, higher SAPS II and APACHE scores and invasive ventilation. Mechanical ventilation, especially with no lung protective parameters, was associated with abnormalities in PFT. Multivariate regression showed more abnormalities in lung function with more extended ICU hospitalization, chronic obstructive pulmonary disease (COPD), chronic kidney disease, invasive mechanical ventilation, and ventilation with higher plateau pressure, and more abnormalities in CT-scan with older age, more extended ICU stay, organ solid transplants and ventilation with higher positive end-expiratory pressure (PEEP). Conclusions: Most patients with severe COVID-19 still exhibit abnormalities in CT scans or lung function tests three to six months after discharge.

Abstract
Introduction: Critical care survivors sustain a variety of sequelae after intensive care medicine (ICM) admission, and the Coronavirus Disease 2019 (COVID-19) pandemic has added further challenges. Specifically, ICM memories play a significant role, and delusional memories are associated with poor outcomes post-discharge including a delayed return to work and sleep problems. Deep sedation has been associated with a greater risk of perceiving delusional memories, bringing a move toward lighter sedation. However, there are limited reports on post-ICM memories in COVID-19, and influence of deep sedation has not been fully defined. Therefore, we aimed to evaluate ICM-memory recall in COVID-19 survivors and their relation with deep sedation. Materials/Methods: Adult COVID-19 ICM survivors admitted to a Portuguese University Hospital between October 2020 and April 2021 (second/third "waves") were evaluated 1 to 2 months post-discharge using "ICU Memory Tool," to assess real, emotional, and delusional memories. Results: The study included 132 patients (67% male; median age = 62 years, Acute Physiology and Chronic Health Evaluation [APACHE]-II = 15, Simplified Acute Physiology Score [SAPS]-II = 35, ICM stay = 9 days). Approximately 42% received deep sedation (median duration = 19 days). Most participants reported real (87%) and emotional (77%) recalls, with lesser delusional memories (36.4%). Deeply sedated patients reported significantly fewer real memories (78.6% vs 93.4%, P = .012) and increased delusional memories (60.7% vs 18.4%, P < .001), with no difference in emotional memories (75% vs 80.4%, P = .468). In multivariate analysis, deep sedation had a significant, independent association with delusional memories, increasing their likelihood by a factor of approximately 6 (OR = 6.274; 95% confidence interval = 1.165-33.773, P = .032), without influencing real (P = .545) or emotional (P = .133) memories. Conclusions: This study contributes to a better understanding of the potential adverse effects of deep sedation on ICM memories in critical COVID-19 survivors, indicating a significant, independent association with the incidence of delusional recalls. Although further studies are needed to support these findings, they suggest that strategies targeted to minimize sedation should be favored, aiming to improve long-term recovery.

Abstract
OBJECTIVES This study aimed to evaluate maternal and perinatal outcomes in pregnancies after kidney transplant (KT) and the impact of pregnancy on graft function. METHODS A descriptive and retrospective case-control study included 43 pregnancies in women after KT, followed in our institution, from January 1991 to December 2019. The control group included 200 non-transplanted pregnant women. Statistical analysis used SPSS 25.0 (SPSS Inc., Chicago, IL), and a p value of .05 was considered statistically significant. RESULTS We studied 43 pregnancies in 37 KT women. The live birth rate of KT pregnant was 81.4%. The mean interval between transplantation and pregnancy was 4.6 years (range 1-16). We found a higher rate of obstetric complications in pregnancies after KT: miscarriage (14.0%, OR 6.7 (2.0-22.1), p < .001), preeclampsia (31.4%, OR 25.7 (7.7-85.3), p < .001), and fetal growth restriction (37.1%, OR 37.6 (9.9-142.3), p < .001). The rate of urogenital infections and anemia during pregnancy was higher in the KT group (p < .001). The gestational age at delivery was 35.0 ± 2.8 weeks and premature delivery was observed in 24 (68.6%) cases. The cesarean rate was higher in the KT group (p < .001). In the KT group, there were two neonatal deaths due to prematurity complications. Renal function deterioration, measured by serum creatinine levels, was observed in two pregnancies. Immunosuppressive therapy was used in all pregnancies after KT, and dosage escalation of immunosuppressive therapy was necessary for 69.8%. CONCLUSIONS A higher rate of adverse obstetric outcomes was found in KT pregnant. Kidney function remained stable in most pregnancies. An antenatal and postpartum multidisciplinary approach is essential to improve outcomes and minimization of complications.

Abstract
INTRODUCTION Pregnancy in patients with autoimmune disorders is associated with an increased risk of adverse outcomes. Sjögren's syndrome (SS) is one of the most common among autoimmune diseases. Presently data regarding the impact of SS on obstetric outcomes are scarce and inconclusive. This study aims to evaluate the impact of SS on maternal-fetal and neonatal outcomes compared with pregnancy outcomes in the general population. MATERIAL AND METHODS A retrospective case-control study included 26 pregnancies in SS patients and a healthy control group (CG), followed in a Portuguese tertiary center, between 2015 and 2020. Baseline maternal data were collected, and maternal-fetal and neonatal outcomes were evaluated. Statistical analysis used SPSS 25.0, and a p-value of 0.05 was considered statistically significant. RESULTS All pregnancies occurred after the diagnosis of SS, with a mean exposure time between diagnosis and pregnancy of 4.92 ±2.78 years. In the SS group, the incidence of ANA, anti-Ro/SSA, and anti-La/SSB antibodies positivity was 80.8%, 61.5%, and 46.2%, respectively. Hydroxychloroquine (HCQ) was used in 57.7%.Miscarriage was significantly higher in the SS group (19.2% vs. 1.8%, p < 0.01). There was a higher prevalence of fetal growth restriction (OR 11.16, 95% CI: 0.96-129.26). Preterm delivery (9.5% vs. 5.6%, p = 0.503) and mean birth weight (2998.16 g vs. 3155.79 g, p = 0.178) did not differ significantly between the groups. In the SS group, admission to the neonatal intensive care unit (NICU) rate was increased (OR 71.67, 95% CI: 3.78-1357.16). Three pregnancies were complicated by congenital heart block (CHB) (14.3% vs. 0%, p = 0.015). In all cases, the diagnosis was performed during second trimester of pregnancy, and betamethasone was administered. CONCLUSIONS Women with SS had a significantly higher incidence of miscarriage, admission to NICU, and CHB than controls. Congenital heart block was the most critical condition that affects the offspring of mothers with SS. Successful pregnancy in the study group was possible with prenatal monitoring and a multidisciplinary approach.

Abstract
Introduction Evidence suggest that critically ill COVID-19 patients are at higher risk of developing anxiety symptoms, which may be related to or exacerbated by patients concerns regarding their health status and recovery. Objectives To assess anxiety symptoms in critically ill COVID-19 survivors, 1-2 months after hospital discharge and to analyze its association with concerns reported by patients regarding their own health status and recovery. Methods In the framework of MAPA prospective research, this preliminary study included COVID-19 patients admitted in the Intensive Care Medicine Department (ICMD) of a University Hospital. Patients were excluded if they had an ICMD length of stay (LoS) ≤24h, terminal illness, major auditory impairment or inability to communicate at the evaluation time. Participants were assessed at a scheduled telephone follow-up appointment, with Generalized Anxiety Disorder Scale (GAD-7). Additional questions were asked to assess the survivors’ post-discharge concerns regarding discrimination against for COVID-19, infection of a family member, re-infection or sequelae related to COVID-19. Results Eighty-three patients were included (median age=63 years; 63% male) and 24% had anxiety symptoms. Anxiety scores were higher in survivors who reported being afraid of being discriminated against for COVID-19 (30% vs 10%; p=0.034), being re-infected (100% vs 79%; p=0.032) and having sequelae (94% vs 44%; p<0.001). Conclusions These findings revealed that anxiety is common in COVID-19 survivors and is associated with post-discharge patients concerns that may limit patient daily living. This study emphasizes the importance of psychological assessment and follow-up of the COVID-19 survivors, in order to support these patients recovery. Disclosure No significant relationships.

Abstract
Introduction A higher risk of mental health consequences in critical COVID-19 patients is expected due to several reasons, including prolonged mechanical ventilation with exposure to high sedation. In this context, post-discharge depression has been reported in previous COVID-19 studies, with a profound impact on patients’ health-related quality of life (HRQoL). Objectives To identify depressive symptoms in COVID-19 survivors 1-year after hospital discharge and to analyse its association with HRQoL. Methods As part of the longitudinal MAPA project, this study enrolled critical COVID-19 patients admitted in the Intensive Care Medicine Department of a University Hospital (March-May 2020). Participants were assessed through telephone by an intensive care nurse and a psychologist, with the Patient Health Questionnaire (PHQ-9) (depressive symptoms), EuroQol five-dimension five-level questionnaire (EQ-5D-5L) and EQ-Visual Analogue Scale (EQ-VAS) (global health status patient record). Results A sample of 55 survivors (median age=66 years; 69% males) were included, with 20% showing depressive symptoms. Pain/discomfort (67%) and anxiety/depression (67%) were the most EQ-5D-5L domains reported. Survivors scoring for depression had more problems in all HRQoL areas (mobility:91%vs.48%, p=0.015; self-care:64%vs.27%, p=0.035; usual activities:91%vs.50%, p=0.017; pain/discomfort:100%vs.59%, p=0.010; anxiety/depression:100%vs.59%, p=0.010). Moreover, they had a lower EQ-VAS median, corresponding a worse self-perception of health status (50vs.80, p=0.010). Conclusions Even after 1-year, a significant proportion of survivors presented depressive symptoms with repercussions in all HRQoL dimensions and association with worse self-perception of global quality of life. Taking this in mind, early screening and treatment of depression in COVID-19 survivors will be crucial, minimizing its impact on quality of life. Disclosure No significant relationships.

Abstract
Introduction Severe COVID-19 survivors experience long-term neuropsychiatric morbidity, particularly those who developed delirium, with a negative impact on health-related quality of life (HRQoL). Objectives To identify the cases of delirium in severe COVID-19 patients and to describe its association with post-hospital discharge HRQoL. Methods In the context of the longitudinal MAPA project, we included adult patients (≥ 18 years old) admitted with COVID-19 to the Intensive Care Medicine Department (ICMD) of a Portuguese University Hospital (October 2020-April 2021). Exclusion criteria were: ICMD length of stay ≤24h, terminal illness, major auditory loss, or inability to communicate at the time of assessment. Delirium during ICMD stay was ascertained based on patients’ clinical records. HRQoL was evaluated using the 5-Level EQ-5D questionnaire (EQ-5D-5L), at a scheduled telephone follow-up appointment on average 1-2 months after hospital discharge. Results Overall, 124 patients were included with a median age of 62 (range: 24-86) years, being mostly male (65%). About 19% had delirium, 42% were deeply sedated and 43% required invasive mechanical ventilation. Most survivors reported problems on the EQ-5D-5L domains: usual activities (85%), mobility (73%) and anxiety/depression (65%). Patients with delirium reported more pain/discomfort (75%vs46%; p=0.011) and considerably anxiety/depression (83%vs60%; p=0.032). Conclusions These findings pointed that COVID-19 patients who experienced delirium reported worse HRQoL, regarding pain/discomfort and anxiety/depression. This study highlights the importance of not only prevention but also early screening of delirium during hospital stay, as well as the crucial role of the timely interventions at discharge, in order to minimize delirium long-term impacts.

Abstract
Introduction Long-term neuropsychiatric consequences of critical illness are well known. Therefore, it is expected that critical COVID-19 patients might also present several psychiatric symptoms such as depression, with inevitable negative effect on health-related quality of life (HRQoL), commonly used as an indicator of illness and treatment impact. Objectives To identify depressive symptoms in critical COVID-19 survivors and to examine its association with HRQoL domains. Methods This preliminary study involved critical COVID-19 patients admitted into the Intensive Care Medicine Department (ICMD) of a University Hospital, between October and December of 2020. Patients with an ICMD length of stay (LoS)≤24h, terminal illness, major auditory loss, or inability to communicate at the follow-up time were excluded. From 1-2 months after discharge, all participants were evaluated by telephone at follow-up appointment, with Patient Health Questionnaire (PHQ-9) (depression) and EuroQol 5-dimension 5-level EQ-5D-5L (HRQoL). This study is part of the longitudinal MAPA project. Results Eighty-three patients were included with a median age of 63 years (range: 31-86) and the majority were male (63%). The most reported problems on EQ-5D-5L domains were usual activities (82%) and mobility (76%). About 27% presented depressive symptoms, and with more problems of self-care (68%vs41%; p=0.029), pain/discomfort (86%vs49%; p=0.002), and anxiety/depression (96%vs54%; p<0.001). Conclusions These preliminary results are in line in previous studies in critical COVID-19 survivors, with depression being associated with worse HRQoL. Bearing this in mind, follow-up approaches with an early screening and treatment of these psychiatric symptoms will be fundamental to optimize the recovery of these patients.

Abstract
If managing COVID-19 alone was a major challenge, one can expect an even greater challenge in certain scenarios, such as patients with kidney disease - including kidney transplant recipients (KT) – or pregnant women. When things could not get any worse, we just met the peculiar art of overcomplicating things: pregnant kidney and simultaneous kidney-pancreas (SKP) transplant recipients with COVID-19. Gleeson and colleagues (Imperial College, London) described the first similar case in April 2020. We describe two cases of pregnant KT and SKP transplant recipients with COVID-19, at different stages, and their evolution until delivery. Maternal and fetal outcomes are significantly affected by both KT and COVID-19, requiring a multidisciplinary approach with a well-trained team of obstetricians and nephrologists, as we will describe.

Abstract
INTRODUCTION The demographic and professional characteristics of specialists in Obstetrics and Gynecology registered in Portugal are presented and current and future needs assessed. MATERIAL AND METHODS An analysis of the data from Instituto Nacional de Estatística, Ordem dos Médicos and a survey sent to the directors of the departments of Obstetrics and Gynecology of Portuguese hospitals was perfomed. In order to calculate the necessary number of specialists, established indicators of the activity of the specialty were used. RESULTS In 2018, there were 1 437 441 consultations of Obstetrics and Gynecology, 89 110 major gynecologic surgeries and 85 604 deliveries. For that, 1065 Obstetrics and Gynecology physicians, working 40 hours per week, with no more than 40% aged 55 years of age and older or including 30 residents per year, are deemed necessary. According to the National Institute of Statistics, in the same year there were 1143 specialists in Portuguese hospitals, of which 234 worked in private hospitals. On the other hand, 1772 specialists were registered with the Ordem dos Médicos: 1163 (66%) were aged 55 years old or above and 84% of specialists under the age of 40 were females. In 2020, there were 864 specialists, 46% of which aged years of age and older working in 39 out of the 41 public or public-private departments that answered the survey. In 2035, an increase of 7% in the required number of specialists is expected. CONCLUSION In Portugal, there is not lack of Obstetrics and Gynecology specialists in absolute numbers, but the large number of specialists aged 55 years of age and older, who are exempt from shifts in emergency department work, and the existence of regional asymmetries contribute to the perpetuation of some shortages of these healthcare professionals in several departments, namely in public hospitals.

Abstract
Background: Behçet's disease (BD) is a rare chronic multisystemic vasculitis of unknown etiology. It is usually diagnosed between the 2nd and 4th decades of life, so its association with pregnancy is not unusual. This study aims to characterize the evolution of pregnancy in a group of pregnant women with BD and the impact of this pathology in embryo-fetal morbidity. Methods: A retrospective case-control study included 49 pregnancies in women suffering from BD, followed in our institution. Pregnancy outcomes were compared with a control group of healthy pregnant women. Two controls per case were randomly selected. Statistical analysis used SPSS 25.0, and a p-value of 0.05 was considered statistically significant. Results: Forty-nine pregnancies were included in 27 patients with BD. BD exacerbation occurred in 32.6% of the pregnancies. There were no significant statistical differences between the two groups regarding the rate of preterm delivery, gestational diabetes, and preeclampsia (p>0.05). In the BD group, we found a higher rate of miscarriage (24.5%) and fetal growth restriction (FGR, 13.3%, p<0.05). In the study group, 13 (32.5%) of the pregnant patients did not need treatment. The cesarean rate was significantly higher in the BD group (43.2% vs 20.4% in the control group, p<0.05), and there were no significant differences in median gestational age at the time of delivery (p>0.05). The birth weight of newborns did not differ significantly between the groups. There was no association of BD with maternal morbidity and neonatal complications. Conclusion: In this study, the majority of pregnant with BD did not present clinical exacerbation of their pathology. However, BD may have an adverse influence on pregnancy outcomes. FGR and miscarriage rates were significantly higher in the study group.

Abstract
During pregnancy, the maternal immune system is challenged to tolerate a semi-allogenic fetus. A shift toward a tolerogenic profile is essential to ensure a healthy fetal and placental development. One of the most important mechanisms involved in the maternal immune tolerance towards the fetal antigens is expressed in the activity of the regulatory T (Treg) and Th17 cells. The behavior and equilibrium of these two T lymphocyte populations were rarely studied in normal healthy pregnancies through the beginning of gestation to the postpartum period. We conducted a prospective longitudinal observational study where peripheral blood lymphocyte subsets were analyzed in each trimester of pregnancy and postpartum period in a group of healthy pregnant women. Our study observed a consistent reduction in peripheric Treg cell count through all pregnancy while the Th17 cell count remained stable. The Th17/Treg ratio increases significantly throughout pregnancy to the postpartum period. These changes could be justified by the migration of the immunotolerant Treg cells to the maternal decidua and lead to the establishment of a systemic pro-inflammatory profile by the end of pregnancy. This data could explain why systemic syndromes like preeclampsia develop in susceptible women during the second half of pregnancy or why many autoimmune disorders flourish in the first weeks postpartum.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) is a life-threatening disorder that affects women at reproductive age. We evaluate the clinical impact of pregnancy in a cohort of Portuguese SLE patients and the risk factors associated with maternal and fetal adverse outcomes. METHODS A retrospective observational study that included all pregnant women with SLE managed at a Portuguese tertiary hospital, between January 1993 and December 2019. Baseline maternal information was collected, and maternal-fetal and neonatal outcomes were evaluated. Disease activity before and during pregnancy was assessed. RESULTS We included 215 pregnancies from 143 patients. Lupus nephritis was present in 20.0% and antiphospholipid syndrome (APS) in 21.9% of the cases. Preconception consultation was performed in 86.9% of the pregnancies, and 92.5% of the patients had no or low disease activity at conception. During gestation, 79.6% of the patients were under treatment, and hydroxychloroquine (HCQ) was the most commonly used drug (63.7%). Low-dose acetylsalicylic acid (ASA) was prescribed at conception in 87.9% of the patients. The live birth rate was 84.2%. An adverse pregnancy outcome (APO) occurred in 41.4% of the pregnancies. A miscarriage rate of 15.3% and a preterm delivery rate of 15.4% were found. Preeclampsia and fetal growth restriction complicated 13.1% and 14.0% of the gestations, respectively. Neonatal lupus occurred in 7.1% of the newborns, and there were 2 cases of congenital heart block. Significant risk factors for the development of AOP were disease activity at conception, lupus flare, hypocomplementemia, positivity for lupus anticoagulant, and APS. The use of ASA was significantly associated with a reduced incidence of miscarriage. An SLE flare was diagnosed in 16.3% of the cases. We identified as risk factors for lupus flares the presence of active disease at conception, a previous history of lupus nephritis, and the use of chronic medication. HCQ use during pregnancy was associated with a significant reduction of flare incidence during pregnancy and postpartum. CONCLUSIONS Pregnancy in an SLE patient is associated with an increased incidence of adverse obstetric outcomes. Good disease control before pregnancy and adequate treatment, especially with HCQ, is crucial to achieving the best obstetric results.

Abstract
Pregnancy in systemic lupus erythematosus (SLE) patients is associated with an increased risk of adverse outcomes. During pregnancy, SLE patients have a higher rate of miscarriage, stillbirth, preterm delivery, fetal growth restriction, or hypertensive disorders of pregnancy. To date, only a few case-control studies were published with the purpose to evaluate the magnitude of risk associated with pregnancy in lupus patients. The aim of our study was to evaluate the maternal and fetal outcomes in a cohort of Portuguese SLE patients and to compare it with a group of healthy pregnant women. We conducted a retrospective case-control study that included all pregnant women with SLE managed at a Portuguese tertiary center, between 2010 and 2019. Pregnancy outcomes were compared between SLE patients and a group of matched healthy pregnant women. Baseline maternal data was collected, and maternal-fetal and neonatal outcomes were evaluated. One hundred twenty-four SLE pregnancies were included. Of the patients, 95.2% were in remission at conception. In 13.7% of cases, a lupus flare was diagnosed during gestation and in 17.9% in the postpartum period. The live birth rate was 84.6%, and the incidence of adverse outcomes was 40.3% (OR 2.64, 95% CI 1.67-4.18). Considering only patients in remission at conception, the presence of adverse outcomes remained significantly higher (36.8% vs. 20.3%, P < 0.01). Miscarriage rate was 15.3% (OR 5.85, 95% CI 2.57-13.34) and preterm delivery occurred in 12.4% of the patients (OR 1.72, 95% CI 0.83-3.57). Preeclampsia prevalence was higher in SLE patients (OR 3.92, 95% CI 1.32-11.57). In the SLE group, the newborn admission to an intensive care unit rate was increased (OR 4.99, 95% CI 1.47-16.90). No neonatal or maternal deaths were reported. In our study, pregnancy with SLE was associated with an increased incidence of adverse outcomes, even in a population of SLE patients with well-controlled disease.

Abstract
Introduction
Breast cancer is a worldwide public health issue. The distribution of the disease presents different behavior depending on the region. In Brazil, for the triennium 2020/2022, approximately 66.28 per 100,000 new cases are expected each year, with the highest incidence in the southeast region 81.06 per 100,000. The region of this study has high mortality rates from the disease and several environmental contaminants classified as carcinogenic.
Methodology
A spatial and temporal ecological study of the breast cancer distribution in the municipalities of the Baixada Santista with secondary data from 2000 to 2011, in women 20 years or older. The cancer data of 3,233 cases were provided by the Oncocentro Foundation of São Paulo, of the contaminated areas were provided by the Technology of Environmental Sanitation Company, and the population at risk were provided by the State Data Analysis System. Standardized coefficients of annual breast cancer rates for each municipality, to characterize exposure, an indicator of contamination per municipality was constructed. Pearson's correlation was used to analyze breast cancer rates and environmental contamination rates. Cartographic sequencing to analyze the distribution and spatiotemporal evolution of outcome and exposure. Trend analysis used linear regression.
Results
The municipality of Santos presented the highest rates of the disease. Pearson's correlation was positive, with r = 0.7 (p = 0.036). Spatially, the most contaminated areas had the highest rates of breast cancer, except in one municipality. Trend analysis in eight of the nine municipalities in the region signaled an increased number of cases.
Conclusions
The study confirmed that environmental contamination interferes with the distribution of breast cancer and the temporal trend signaled an increase in the disease in eight of the nine municipalities in the region.

Abstract
Abstract
Introduction
The Região Metropolitana da Baixada Santista (RMBS) is considered as a region with the worst maternal and child mortality rates in the state of São Paulo, Brazil. Besides this, RMBS has the worst rates of environmental contamination. High-Risk Pregnancy is one of the factors that lead to a higher chance of morbidity and mortality of the mother and fetus binomial.
Objective
Evaluate the relationship between exposure to environmental contaminants and high-risk pregnancy.
Methodology
Case-control study, using a probabilistic sample composed of 402 pregnant women divided into with and without high-risk pregnancy. The instrument used was a self-administered questionnaire and secondary data on contaminated areas obtained from the Environmental Company of the State of São Paulo. Descriptive analysis, Chi-square test, univariate and multiple logistic regression analysis were performed. The participants were also georeferenced by place of residence.
Results
It was observed an association, by chi-square test between high-risk pregnancy and age over 35 years (p < 0.05), use of insecticide (p < 0.001), consumption of foods packed in plastics (p = 0.050) and manipulation with oil paint (p = 0.002). The final multiple logistic regression model demonstrated that those who live in contaminated areas are 2 times more likely to have a risk pregnancy (OR = 1.993; 95%CI: 1.02; 3.90), as well as identified as jointly important risk factors for pregnancy: working in health services (OR = 3.97 (95%CI: 1.00; 16.09)), use of insecticide (OR = 3.45 (95%CI: 1.66; 7.16)) and use of oil paint (OR = 6.96 (95%CI: 1.38; 35.09)).
Conclusions
Environmental contaminants play an important role in pregnancy, and mitigating measures are needed to improve the environment and reduce high-risk pregnancy in RMBS.
Key messages
Exposure to the environmental contaminants is an important rik factor in the pregnancy. The Região Metropolitana da Baixada Santista (RMBS) is considered as a region with the worst maternal and child mortality rates in the state of São Paulo, Brazil.

Abstract
Abstract
BACKGROUND
The number of lead removal of cardiac implantable electronic devices (CIED) has increased in recent years. The recent European registry (ELECTRa) did not include all European centers and not all lead extractions are possible to be performed transvenously.
AIMS
We aim to analyze all lead extraction procedures (transvenous or open surgery) performed in our center and the short- and long-term follow-up of these patients (pts).
METHODS
We retrospectively reviewed all lead extractions performed from 2008 to 2017. We analyzed pts´ characteristics (personal history, cardiovascular risk factors, indication for device implantation, laboratory tests); indications for extraction; techniques used and personnel that participate in the procedure, complications peri- and post-procedural and short and long-term follow-up.
RESULTS
A total of 189 pts (330 leads) were included (mean 69 ± 14 years, 73% male). The follow-up was 54 (IQR 20-87) months. Median time after implant was 47 (IQR 19-98) months. Lead explant was performed in 30 patients (16%) and lead extraction (at least one lead implanted >1 year or a lead requiring assistance of specialized equipment) in 159 (84%). Indications for removal are presented in figure A. In those who were infected, isolation of the microorganism was possible in 35% and Staphylococcus aureus was the most common agent (51%). 101 procedures (53%) occurred in the operating room, while 89 (47%) were performed in the electrophysiology laboratory, but 47% of those with the participation of a surgeon. On the total, cardiac surgeons were responsible for 75% of the procedures. Removal was tried in 330 leads (98 atrium lead, 199 right ventricle lead (79 defibrillator lead) and 33 coronary sinus lead). Of those, 298 were completely removed, 14 were partially removed (<4cm of a lead remained in the patient body) and 18 were not removed (radiologic failure). On an individual patient basis, clinical success was achieved in 185 patients (97%). Techniques used in the 330 leads were distributed in figure B. Surgical approach was necessary in 14 pts due to unsuccessful transvenous removal (n = 3), large vegetation in the lead (n = 4), concomitant valvular endocarditis (n = 2), other indication for open surgery (n = 4) and complicated transvenous removal (n = 1). Complications occurred in 6 patients: 3 persistent infections, 1 stroke, 2 vessel rupture. Related-procedural mortality was 1.5% (n = 3). The long-term survival of pts who performed open heart surgery was not different from those who underwent transvenous lead removal (logrank, p = 0.27) (figure C).
CONCLUSION
Although being a low volume center (19 procedures/year) and including pts with transvenous and open surgery, lead removal was associated with a high success rate with low all cause complication and mortality rates. Emergent surgery due to acute complications was very rare (0.5%) and open heart surgery was mostly programmed and not associated with a worse outcome.

Abstract
BACKGROUND The aim of this study was to assess the 3-year objective and subjective outcomes of patients with complex anorectal fistula treated with Video-Assisted Anal Fistula Treatment (VAAFT). Furthermore, we evaluated the risk factors associated with recurrence. METHODS All consecutive patients with complex anorectal fistula who underwent VAAFT in Beata Vergine Hospital of Mendrisio, Switzerland, from January 2013 to January 2016, were enrolled. Patients with suspicion or diagnosis of Crohn's disease, malignancy, previous history of radiotherapy or radical pelvic surgery were excluded. Preoperative clinical assessment based upon medical history, physical examination and endosonography, was performed in all patients. Data regarding subjective outcomes (the Patient Global Impression of Improvement, patient satisfaction scores and Wexner score), objective cure rate (absence of fistula at clinical examination), and adverse events were collected during follow-up. Uni and multivariate analysis were performed to investigate outcomes. RESULTS One hundred and four patients had VAAFT. At 3-year follow-up, 96 patients (92.3%) were available for the evaluation. At 3 years after surgery, 81 of 96 patients (84.4%) declared themselves cured (p = 0.60). Similarly, at 3-year evaluation, 80 of 96 patients (83.3%) were objectively cured (p = 0.52). No serious intraoperative or postoperative complications were reported. All recurrences were treated with a repeat VAAFT procedure resulting in a complete healing. Uni and multivariate analysis of variables potentially involved in the failure of VAAFT showed that age ≥ 50 years was the only factor associated at risk of recurrence. CONCLUSIONS VAAFT is a highly effective safe procedure for the treatment of anorectal fistula, with a low recurrence rate at 3-year follow-up. However, our study demonstrated that age ≥ 50 years is a risk factor for failure of VAAFT.

Abstract
BACKGROUND The „gold standard“ for prenatal diagnosis of aneuploidies is provided by the karyotype, which has high accuracy, but is dependent on invasive procedures, which generate risk of fetal loss. Different methodologies of development of noninvasive prenatal genetic tests (NIPT) for tracking aneuploidies, including sex chromosomes, have been made available for clinical use, for some microdeletions and triploids and for exclusion of paternity. These exams make use of three methodological tools: s-MPS, t-MPS and SNP. Genetic tests, despite the high cost, cover a broader range of clinical applications, have the advantage that can be performed early, with high accuracy, and low false positive rate. Type of article: Review. SETTING Department of Obstetrics and Gynecology, Science College of Santa Casa of São Paulo (FSMSCSP), São Paulo-SP, Brazil. DESIGN AND METHODS This study was a non-asystematic review, which searched PubMed / MEDLINE as a research source and aimed at the compilation of data, which allowed approaching the evolution, the technical and methodological advances of the available tests, the recognition of its benefits, limitations and future perspectives on NIPT. CONCLUSION NIPT stand out for being applied earlier during the pregnancy with high accuracy and low false-positive rates, including a broad spectrum of clinical applications. The t-MPS is a recent technique used to evaluate aneuploidy that shows greater accuracy and lower cost than the s-MPS, but that is limited to being applied only to the most common aneuploidies. The SNP technique can search for more genetic conditions, besides presenting better accuracy.

Abstract
Background The aim of this study was to compare the WaveOne Gold and ProTaper Next systems regarding the time spent preparing simulated canals performed by an inexperienced student.
Material and Methods 0 simulated L-shaped canals were randomly divided into two groups (n = 40) and numbered in order of instrumentation. Canals were instrumented with WaveOne Gold (group 1) and ProTaper Next (group 2) systems. The effective instrumentation time and the number of instrumentation cycles were recorded. All procedures were performed by the same operator. Statistical analysis was obtained by the Mann - Whitney, Kruskal - Wallis test with significance of p<0.05.
Results There were no statistically significant differences regarding the mean instrumentation time between the two instrumentation systems. The instrumentation time decreased over the experimental period, regardless of the technique used.
Conclusions Through a short learning curve, an inexperienced operator can prepare simulated canals in a very predictable time. Time spent was similar in a multi-file instrument system (ProTaper Next) and a single-file system (WaveOne Gold). Key words:Dental education, endodontics, preclinical, root canal preparation, undergraduate.

Abstract
The polyphenol resveratrol (3,5,4'-trihydroxystilbene) is a well-known plant secondary metabolite, commonly used as a medical ingredient and a nutritional supplement. Due to its health-promoting properties, the demand for resveratrol is expected to continue growing. This stilbene can be found in different plants, including grapes, berries (blackberries, blueberries and raspberries), peanuts and their derived food products, such as wine and juice. The commercially available resveratrol is usually extracted from plants, however this procedure has several drawbacks such as low concentration of the product of interest, seasonal variation, risk of plant diseases and product stability. Alternative production processes are being developed to enable the biotechnological production of resveratrol by genetically engineering several microbial hosts, such as Escherichia coli, Corynebacterium glutamicum, Lactococcus lactis, among others. However, these bacterial species are not able to naturally synthetize resveratrol and therefore genetic modifications have been performed. The application of emerging metabolic engineering offers new possibilities for strain and process optimization. This mini-review will discuss the recent progress on resveratrol biosynthesis in engineered bacteria, with a special focus on the metabolic engineering modifications, as well as the optimization of the production process. These strategies offer new tools to overcome the limitations and challenges for microbial production of resveratrol in industry.

Abstract
Recurrent pregnancy loss (RPL) affects approximately 1%-2% of reproductive women. Auto- and cellular immune responses seem to be associated with RPL. Vitamin D (VD) has been shown to play a role in the modulation of the immune system. Effects of VD deficiency (VDD) in pregnancy have been associated with preeclampsia, gestational diabetes, fetal growth restriction, preterm labor, and sporadic spontaneous abortion (SA). We systematically reviewed articles that studied women with 2 or more SA and its association with VD. Eleven studies were included. Studies reported a high prevalence of VD insufficiency (VDI) or VDD in women with RPL and suggested that this could be associated with immunological dysregulation and consequently with RPL. Immunological benefits were reported in the peripheral blood of women with RPL after VD exposure. Thus, it is possible to speculate a beneficial role for VD supplementation in RPL. It seems that there are not differences in the vitamin D receptor (VDR) and CYP27B1 expression in endometrium of women with RPL but, in villous and decidual tissues, RPL women seem to have a decreased expression of VDR and, perhaps, a decreased expression of CYP27B1. Further randomized controlled studies are required to investigate the association between VDD or VDI and RPL.

Abstract
BACKGROUND Distinguishing hydatidiform moles (HMs) from nonmolar specimens and the subclassification of HM are important because complete hydatidiform mole (CHM) is associated with an increased risk of development of gestational trophoblastic neoplasia. However, diagnosis based solely on morphology has poor inter-observer reproducibility. Recent studies have demonstrated that the use of p57KIP2 immunostaining improves diagnostic accuracy for CHM. OBJECTIVES To evaluate the accuracy of p57KIP2 immunostaining compared with molecular genotyping for the diagnosis of CHM. SEARCH STRATEGY Major databases were searched from inception to March 2017 using the terms 'hydatidiform mole', 'p57', and 'genotyping', with their variations, and the search limit for the relevant study design. SELECTION CRITERIA Any cross-sectional study, case series, case-control study, cohort study, or clinical trial that evaluated the accuracy of p57KIP2 immunostaining for the diagnosis of CHM compared with genotyping was included. Case reports, narrative reviews, expert opinions, and animal testing were excluded. DATA COLLECTION AND ANALYSIS Extracted accuracy data were tabulated and pooled using a hierarchical bivariate random effects model. MAIN RESULTS Bivariate meta-analysis produced a summary sensitivity of 0.984 (95% CI: 0.916-1.000) and specificity of 0.625 (95% CI: 0.503-0.736) with significant heterogeneity for specificity (I2 = 71.8, chi-square P = 0.029). The pooled summary diagnostic odds ratio was 56.54 (95% CI: 11.03-289.74) with no heterogeneity (I2 = 0.00%, chi-square P = 0.67). The diagnostic performance of the test was high with an area under the curve of (AUC) 0.980. CONCLUSIONS p57KIP2 immunostaining is accurate when diagnosing CHM. It can be used as an adjunct test in a combination algorithmic approach. TWEETABLE ABSTRACT A meta-analysis to evaluate the accuracy of p57KIP2 compared with genotyping to diagnose CHM.

Abstract
The request for new flavourings increases every year. Consumer perception that everything natural is better is causing an increase demand for natural aroma additives. Biotechnology has become a way to get natural products. γ-Decalactone is a peach-like aroma widely used in dairy products, beverages and others food industries. In more recent years, more and more studies and industrial processes were endorsed to cost-effect this compound production. One of the best-known methods to produce γ-decalactone is from ricinoleic acid catalyzed by Yarrowia lipolytica, a generally regarded as safe status yeast. As yet, several factors affecting γ-decalactone production remain to be fully understood and optimized. In this review, we focus on the aromatic compound γ-decalactone and its production by Y. lipolytica. The metabolic pathway of lactone production and degradation are addressed. Critical analysis of novel strategies of bioprocess engineering, metabolic and genetic engineering and other strategies for the enhancement of the aroma productivity are presented.

Abstract
Aims: The determination of postmortem ethanol is one of the most frequently requested analyses in forensic toxicology and of extreme importance, especially when the concentration is found to be above the legal level for intoxication at one sampling site and below that level at another sampling site. Because of the unavailability of blood samples for toxicological analysis or even contaminated samples, there is an enormous effort to find alternative sampling sites, such as vitreous humor for ethanol analysis. The main purpose of this study was to establish correlations between urine and blood alcohol concentrations collected from different sites and vitreous humor. Methods: Ethanol concentrations were determined in specimens of heart, subclavian and femoral blood, urine and vitreous humor, collected from 21 cadavers who were victims of different causes of death. Determinations of ethanol were performed in duplicate using capillary gas chromatography/flame ionization detector and headspace techniques. Results: Statistical analysis of the results indicated that there were no significant differences among urine and blood samples collected from different sites compared to vitreous humor. Regarding vitreous humor ethanol concentration, Pearson's correlation coefficient was 0.97 for femoral blood and urine, 0.96 for heart blood and 0.94 for subclavian blood. The results demonstrated that all the fluids tested against vitreous humor significantly correlated with P (associated probability for the used correlation tests) B<0.05. Conclusions: Vitreous humor can be considered as an alternative sample to urine and blood specimens.

Abstract
Pregnancy with liver cirrhosis is a rare and dangerous event that exposes mother and fetus to potentially lethal risks. During pregnancy, hepatic decompensation could suffice and the development of hepatic failure and encephalopathy could occur. The incidence of obstetric complications is also increased with a high rate of pre-eclampsia, postpartum bleeding, preterm delivery and stillbirth. We report a case of a 27-year-old woman with autoimmune hepatitis and liver cirrhosis complicated by splenomegaly, oesophageal varices and severe thrombocytopaenia. During pregnancy, close clinical and analytical surveillance was performed. She was medicated with corticosteroids, azathioprine and propranolol. At the 25th week of gestation, an upper gastrointestinal endoscopy was performed to control oesophageal varices. This patient had an uneventful pregnancy until 37 weeks. At 37th week of gestation, after spontaneous rupture of membranes, signs of acute fetal distress were observed, and an urgent caesarean was performed. Good neonatal and maternal outcomes were achieved.

Abstract
OBJECTIVE To discover the differences between women with gestational diabetes mellitus (GDM) who delivered vaginally and those who delivered by cesarean section, and to assess the cesarean rate in this group of women. STUDY DESIGN We divided all pregnant women with GDM into 2 groups: those who had vaginal delivery and those who gave birth by cesarean section (retrospective study of 6 years). RESULTS We evaluated 460 births at term (≥ 37 weeks' gestation), for a total of 240 vaginal births and 220 cesarean births. All occurred in our institution. Of all the variables that were compared between the 2 groups, we found statistically significant differences (p < 0.05) in the following factors: previous history of macrosomia and gestational age at the time of beginning insulin treatment. CONCLUSION Pregnant women with GDM and previous history of macrosomia are more likely to be submitted to cesarean section. Also, the initiation of insulin treatment at an early gestational age is associated with a higher chance of a woman delivering by cesarean section. The cesarean section rate in women with GDM was 47.8%.

Abstract
OBJECTIVE To re-evaluate the safety of hormonal contraceptives (HC) after uterine evacuation of complete hydatidiform mole (CHM). DESIGN Historical database review. SETTING Charing Cross Hospital Gestational Trophoblastic Disease Centre, London, United Kingdom. POPULATION Two thousand four hundred and twenty-three women with CHM of whom 154 commenced HC while their human chorionic gonadotropin (hCG) was still elevated, followed between 2003 and 2012. METHODS We compared time to hCG remission between HC users and nonusers. The relationship between HC use and gestational trophoblastic neoplasia (GTN) development was assessed. The relationship between HC use and a high International Federation of Gynecology and Obstetrics (FIGO) risk score was determined. MAIN OUTCOME MEASURES Time to hCG remission, risk of developing postmolar GTN and proportion of women with high FIGO risk score. RESULTS No relationship was observed between HC use with mean time to hCG remission (HC users versus non-users: 12 weeks in both, P = 0.19), GTN development (HC users versus non-users: 20.1 and 16.7%, P = 0.26) or high-risk FIGO score (HC users versus nonusers: 0% and 8%, P = 0.15). Moreover, no association between HC and GTN development was found, even when an age-adjusted model was used (OR = 1.37, 95% CI 0.91-2.08, P = 0.13). CONCLUSIONS The use of current HC is not associated with development of postmolar GTN or delayed time to hCG remission. Therefore, HC can be safely used to prevent a new conception following CHM regardless of hCG level. TWEETABLE ABSTRACT Non-concurrent cohort study to re-evaluate the safety of low dose HCs after uterine evacuation of CHM.
