Placenta Accreta Spectrum Disorders - The Impact of the Creation of a Multidisciplinary Team on Maternal Outcomes in Portugal / Patologia do espectro do acretismo placentário - O impacto da criação de uma equipa multidisciplinar nos desfechos maternos em Portugal

Abstract Objective To describe a cohort of placenta accreta spectrum (PAS) cases from a tertiary care institution and compare the maternal outcomes before and after the creation of a multidisciplinary team (MDT). Methods Retrospective study using hospital databases. Identification of PAS cases with pathological confirmation between 2010 and 2021. Division in two groups: standard care (SC) group - 2010-2014; and MDT group - 2015-2021. Descriptive analysis of their characteristics and maternal outcomes. Results During the study period, there were 53 cases of PAS (24 - SC group; 29 - MDT group). Standard care group: 1 placenta increta and 3 percreta; 12.5% (3/24) had antenatal suspicion; 4 cases had a peripartum hysterectomy - one planned due to antenatal suspicion of PAS; 3 due to postpartum hemorrhage. Mean estimated blood loss (EBL) was 2,469 mL; transfusion of packed red blood cells (PRBC) in 25% (6/24) - median 7.5 units. Multidisciplinary team group: 4 cases of placenta increta and 3 percreta. The rate of antenatal suspicion was 24.1% (7/29); 9 hysterectomies were performed, 7 planned due to antenatal suspicion of PAS, 1 after intrapartum diagnosis of PAS and 1 after uterine rupture following a second trimester termination of pregnancy. The mean EBL was 1,250 mL, with transfusion of PRBC in 37.9% (11/29) - median 2 units. Conclusion After the creation of the MDT, there was a reduction in the mean EBL and in the median number of PRBC units transfused, despite the higher number of invasive PAS disorders.

Group B Streptococcus rectovaginal colonization screening on term pregnancies: culture or polymerase chain reaction?

OBJECTIVES: The aim of this study was to evaluate if screening Group B Streptococcus colonization by intrapartum polymerase chain reaction could improve intrapartum administration of antibiotic prophylaxis, compared with antepartum culture screening and analyze the sensitivity and specificity of polymerase chain reaction test. METHODS: 198 pregnant women with Group B Streptococcus colonization antepartum culture screening were included. When they arrived at hospital for delivery, two rectovaginal swabs were collected: for culture and polymerase chain reaction method. RESULTS: The rate of Group B Streptococcus colonization antepartum detected by culture was 16.7%; at delivery was 17.2% when detected by culture and 19.7% using polymerase chain reaction method. The rate of inconclusive polymerase chain reaction tests was 0.5%. Considering intrapartum culture screening as gold standard, sensitivity and specificity of polymerase chain reaction test for intrapartum Group B Streptococcus colonization was 97.1% and 95.7%, respectively. The global rate of discordance between antepartum and intrapartum Group B Streptococcus colonization was 6.6%. The rate of women not treated with intrapartum antibiotic prophylaxis in the setting of positive intrapartum culture was significantly lower using intrapartum polymerase chain reaction test (0.5%) than with antepartum culture method (3.5%, p = 0.035). CONCLUSION: The use of intrapartum antibiotic prophylaxis can be more efficient when screening Group B Streptococcus colonization intrapartum by polymerase chain reaction test. Polymerase chain reaction method had a good performance in our study, with high sensitivity and specificity.

Labor induction with a combined method (pharmacologic and mechanical): A randomized controlled trial.

INTRODUCTION: The aim of this study was to compare the effectiveness of a combined misoprostol-Foley catheter induction of labor protocol against the current guidelines of our department. MATERIAL AND METHODS: A randomized trial was conducted comparing two cervical ripening study groups: combined misoprostol-cervical Foley and the current department practice (misoprostol alone or dinoprostone alone). Women were stratified randomly according to parity for the two intervention groups. The primary outcome was defined as time to delivery (in hours). Secondary outcomes were cesarean delivery rate, time to active labor (defined as dilatation 6 cm or greater), delivery within 12 h, delivery within 24 h, maternal length of stay and indication for cesarean delivery. A composite of maternal morbidity and neonatal morbidity were also analyzed. RESULTS: 142 women were randomized into one of the two groups (74 for treatment group and 68 for control group). Demographic and clinical characteristics were similar among the two groups. The primary outcome, the average time to delivery, was faster in the treatment group (22.7 h vs 27.2 h, p = 0.03) and this difference was higher in the nulliparous subgroup (24.2 h vs 29.2 h, p = 0.03). Active phase of labor was achieved faster in the treatment group (17.9 h vs 22.7 h, p = 0.008). The risk for cesarean section was similar in both groups (OR 0.801 (0.527-1.217) vs OR 1.203 (0.871-1.662), p = 0.278). CONCLUSIONS: Our study suggests that the combined method of cervical Foley with vaginal misoprostol for women presenting to induction of labor with unfavorable Bishop scores reduces time to delivery safely. The risk for cesarean section was similar in both groups.

Perinatal management of SARS-CoV-2 infection in a level III University Hospital.

Over the past 4 months, SARS-CoV-2 pandemic has spread all over the world. The lack of understanding of this pandemic epidemiological characteristics, clinical implications and long term consequences have raised concern among healthcare workers. Pregnant women and newborns are a particularly worrisome population since data referring to real infection impact in these patients are scarce and management controversial. We report on the perinatal management of the first consecutive ten mother-infant dyads of SARS-CoV-2 infection complicated pregnancy. All mothers were included in newborn management planning prior to delivery and decided on separation from their newborns; nine decided on postponing breastfeeding until SARS-CoV-2 negativity while maintaining lactation stimulation. No evidence of vertical transmission was found (all NP swab and bronchial secretions SARS-CoV-2 RT-PCR were negative). No newborn developed clinical evidence of infection. In the face of current scientific uncertainty, decisions of perinatal management, such as mother-infant separation and breastfeeding, must involve parents in a process of shared decision making.

Maternal outcomes and risk factors for COVID-19 severity among pregnant women.

Pregnant women may be at higher risk of severe complications associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which may lead to obstetrical complications. We performed a case control study comparing pregnant women with severe coronavirus disease 19 (cases) to pregnant women with a milder form (controls) enrolled in the COVI-Preg international registry cohort between March 24 and July 26, 2020. Risk factors for severity, obstetrical and immediate neonatal outcomes were assessed. A total of 926 pregnant women with a positive test for SARS-CoV-2 were included, among which 92 (9.9%) presented with severe COVID-19 disease. Risk factors for severe maternal outcomes were pulmonary comorbidities [aOR 4.3, 95% CI 1.9-9.5], hypertensive disorders [aOR 2.7, 95% CI 1.0-7.0] and diabetes [aOR2.2, 95% CI 1.1-4.5]. Pregnant women with severe maternal outcomes were at higher risk of caesarean section [70.7% (n = 53/75)], preterm delivery [62.7% (n = 32/51)] and newborns requiring admission to the neonatal intensive care unit [41.3% (n = 31/75)]. In this study, several risk factors for developing severe complications of SARS-CoV-2 infection among pregnant women were identified including pulmonary comorbidities, hypertensive disorders and diabetes. Obstetrical and neonatal outcomes appear to be influenced by the severity of maternal disease.

Systematic screening for SARS-CoV-2 in pregnant women admitted for delivery in a Portuguese maternity.

Objectives The burden of undocumented SARS-Cov-2 infections in Portuguese pregnant women is unknown. At our institution, routine COVID-19 testing was implemented from 19th of March on to all pregnant women who were admitted for delivery. The purpose of the study was to estimate the SARS-CoV-2 infection rate in our obstetric population admitted for delivery. Mathods Between 19th March and May 4th, 184 pregnant women were screened for SARS-CoV-2 infection upon admission. Results Eleven women were positive for SARS-CoV-2, corresponding to a global prevalence of 6.0%. Of these, only two reported symptoms at admission. The prevalence of asymptomatic infection was 4.9%. We report a lower rate of positive cass than other studies. Eighty-two percent of our cases had no symptoms at admission. Conclusions The proportion of asymptomatic infection highlights the importance of universal laboratory screening for all women admitted for delivery as opposed to symptom-based screening.

Periconceptional CMV infection prevention in Portugal: population subgroup study in a tertiary perinatal care center.

Currently in Portugal, universal screening of pregnant women for Cytomegalovirus (CMV) infection is not performed. However, it is recommended to screen all women attending preconception care. We aimed to assess women's attendance to preconception care and if their serologic status regarding CMV was known and/or investigated in that consultation. In this cross-sectional study, we interviewed 240 women admitted to the obstetrical ward of a hospital in the Metropolitan Area of Porto (Portugal) about their adherence to preconception care and collected data regarding their CMV serologic status and its investigation. We found that 71.3% of the women who attended preconception care were not screened for CMV infection. Among primigravida, the screening rate was only of 30.4% (upper limit of CI 95%: 44.8%). There were no statistically significant differences between the private and public sectors of healthcare. We observed attendance to preconception care is high (73.1%). For the population subgroup of the metropolitan area of Porto, attendance to preconception care is at least 66%, with a 95% confidence level. Portuguese guidelines stating a woman's serologic status regarding CMV should be investigated in preconception care are not properly implemented. This suggests guidelines should assure the screening of previously non-screened women during pregnancy.

Medical Termination of Delayed Miscarriage: Four-Year Experience with an Outpatient Protocol / Terminação médica de gravidez inviável do 1° trimestre: quatro anos de experiência com um protocolo de tratamento em ambulatório

Abstract Purpose To evaluate the efficacy of an outpatient protocol with vaginal misoprostol to treat delayed miscarriage. Methods Retrospective analysis of prospectively collected data on women medically treated for missed abortion with an outpatient protocol. The inclusion criteria were: ultrasound-based diagnosis of missed abortion with less than 10 weeks; no heavy bleeding, infection, inflammatory bowel disease ormisoprostol allergy; nomore than 2 previous spontaneous abortions; the preference of the patient regarding the medical management. The protocol consisted of: 1) a single dose of 800 μg of misoprostol administered intravaginally at the emergency department, after which the patients were discharged home; 2) clinical and ultrasonographic evaluation 48 hours later - if the intrauterine gestational sac was still present, the application of 800 μg of vaginal misoprostol was repeated, and the patients were discharged home; 3) clinical and ultrasonography evaluation 7 days after the initiation of the protocol - if the intrauterine gestational sac was still present, surgical management was proposed. The protocol was introduced in January 2012. Every woman received oral analgesia and written general recommendations. We also gave them a paper form to be presented and filled out at each evaluation. Results Complete miscarriage with misoprostol occurred in 340 women (90.2%). Surgery was performed in 37 (9.8%) patients, representing the global failure rate of the protocol. Miscarriage was completed after the first misoprostol administration in 208 (55.2%) women, with a success rate after the second administration of 78.1% (132/169). The average age of the women with complete resolution using misoprostol was superior to the average age of those who required surgery (33.99 years versus 31.74 years; p = 0.031). Based on the ultrasonographic findings in the first evaluation, the women diagnosed with fetal loss achieved greater success rates compared with those diagnosed with empty sac (p = 0.049). Conclusions We conclude this is an effective and safe option in the majority of delayed miscarriage cases during the first trimester, reducing surgical procedures and their consequences.

24/7 Presence of Medical Staff in the Labor Ward; No Day-Night Differences in Perinatal and Maternal Outcomes.

Objective The objective of this study was to assess possible day-night differences in perinatal and maternal labor outcomes in a hospital setting with no day-night differences in the presence of experienced medical staff. Design This was a retrospective study conducted over 5 years between 2008 and 2012. Setting This study was set at the obstetric delivery unit in a tertiary hospital. Population A total of 9,143 singleton deliveries were assessed after 34 weeks of gestation and after exclusion of major congenital malformations, inductions of labor, and elective cesarean sections. Materials and Methods Data were collected using the hospital electronic medical records. Time periods of 8 hours were defined (daytime between 8 am and 4 pm, evening time between 4 pm and 12 pm, and nighttime between 12 pm and 8 am). Differences between the three time periods were assessed using software R Core Team (2013). Main outcome measures were neonatal birth asphyxia, neonatal intensive care unit admission, and neonatal death. Results There were no differences in perinatal and maternal outcomes in the course of the day, apart from a higher incidence of third- and fourth-degree tears during the evening. Neonatal outcome after obstetric emergencies (uterine rupture, partial placental abruption, and cord prolapse) also showed no day-night differences. Conclusion Adverse nighttime-related outcomes may be avoided by the 24/7 presence of experienced medical staff.

Prevention of mother-to-child transmission: experience of a Portuguese centre.

INTRODUCTION: HIV infection during pregnancy still raises controversial issues. Combined antiretroviral therapy (cART) has been successful in reducing mother-to-child transmission (MTCT). Routine screening in pregnancy and in pre-conception consultation proved to be one of the best methods able to get this treatment on time. We review our experience with pregnant patients with HIV infection. MATERIALS AND METHODS: Retrospective and descriptive study. Data obtained from HIV-infected pregnant women from 1999 to 2012 with delivery and subsequent infectious diseases follow-up at our hospital. RESULTS: We evaluated 136 patients (169 pregnancies), with a total of 147 living newborns (2 twin pregnancies) and 1 stillbirth. Median age at pregnancy was 30 (SD 5.7) years. Four patients were HIV-2 infected and one HIV-1+2 infected. 26 (19.1%) women were HCV co-infected and 6 (4.4%) HBV co-infected; 1 patient has HCV and HBV co-infection. Sexual risk for HIV acquisition was determined in 102 (75%) patients and 31 (22.8%) were intravenous drug users. 33/136 (24.2%) women were diagnosed on routine screening in pregnancy, 4 during delivery and 2 immediately after delivery. 36 (26.4%) patients had an AIDS-defining entity before pregnancy and no new opportunistic infections were diagnosed. ART was used in 157 (92.9%) pregnancies and 15 (9.5%) of them were treated only with NRTIs. At the time of delivery 86/144 (59.7%) patients had undetectable viral load (VL) (25 patients without VL determined), 91.7% of those on ART. 119 (70.4%) had a TCD4 cell count above 200 cells/mm(3). MTCT occurred in 3/147 cases (2%): in one mother HIV-1 infection was diagnosed three weeks before delivery, other immediately after delivery and the third woman started cART (2NRTI+1PI/r) in the second trimester of pregnancy, always adherent and without secondary effects, VL at delivery was 50 copies/mL and elective C-section was performed. CONCLUSIONS: The fact that 24% of patients were diagnosed during pregnancy shows the importance of routine screening to all pregnant women. MTCT occurred in three children, but only one was administered cART for prevention.

[Cervical smear, viral load and t cell counting in seropositive HIV women]. / Alterações citológicas em mulheres seropositivas para o VIH. Relação com Carga Vírica e Linfócitos T CD4+

The aim of this study was to compare the T cell counting and viral load in seropositive women for HIV with normal cervical smear and intraepithelial lesions. 87 women were studied, 26 with normal smear, 46 with low grade intraepithelial lesions and 15 with high grade intraepithelial lesions. Women with normal smears showed the lowest viral load and high grade lesions the highest. There were no differences between cervical smear result and T cell counting.

[Granulosa cell tumor and pregnancy]. / Tumor de células da granulosa e gravidez.

Ovary tumor and pregnancy is a rare and serious condition with an unexpected outcome as it can interfere with the course of pregnancy. The authors report a case of a large juvenile granulosa cell tumor diagnosed at 33 weeks of pregnancy during a routine ultrasonographic examination. Pain, nausea and vomiting at the 35th week brought the suspicion of torsion.

[Clinical impact of ultrasonography between the 10th and the 13th week of pregnancy]. / Impacto clínico da ecografia entre as 10 e as 13 semanas de gravidez.

The authors aimed to assess the impact of a routine ultrasound examination performed between 10 and 13 weeks of pregnancy. During a thirty month period, 778 ultrasound examinations between 10 and 13 weeks of pregnancy were performed, in women referred to our hospital. Transvaginal ultrasound was systematically adopted and the parameters obtained were introduced in a computerized data base. Biographic data, first day of menses (whenever possible), menstrual cycle characteristics, eventual use of hormonal contraception in the three months before last menses, antecedents of chromosomal abnormalities, number of foetuses and chorionicity, foetal vitality, crown-rump length, nuchal translucency and foetal heart rate were registered in all examinations. The median gestational age at the time of examination was 12.5 weeks (9-14.3). The median of maternal age was 29 years (14-44), maternal age prevalence higher or equal to 35 years was 17%. Fifty two per cent of women had usually regular menstrual cycles and 11% ignored last menses. In 74% of cases discrepancy between amenorrhea and ultrasound derived gestational age was inferior to one week and in 19% superior. The median of nuchal translucency was 1.4 mm (0.5-10), 7% of all cases had a nuchal translucency higher or equal to 2.5 mm. If maternal age criteria had been decisive for diagnostic invasive procedures, they would have been made in 135 cases. Considering nuchal translucency value combined with maternal age, it should have been done in 63 cases. In our series, invasive testing was performed in 31 (5%) cases. Eight women with fetuses with abnormal karyotypes decided for termination of pregnancy. The importance of ultrasound examination between 10 and 13 weeks seems unquestionable, allowing the correction of gestational age, multiple pregnancy characterisation and chromosomal abnormalities screening.
