RESUMO

BACKGROUND: The COVID-19 pandemic is an ongoing global healthcare crisis that negatively affects pregnant women. Although patients with an acute infection during pregnancy have been widely studied, information regarding labor and delivery while infected is sparse. The aim of the study was to ascertain maternal, obstetrical, and perinatal outcomes of women who gave birth while infected with SARS-CoV-2. METHODS: Patients diagnosed with COVID-19 during pregnancy at a tertiary medical center in 4/20-2/21 were identified by a retrospective database search. Those with an active intrapartum SARS-CoV-2 infection were compared with those who recovered at least 10 days before labor and delivery. RESULTS: Of the 176 women included in the study, 84 had a SARS-CoV-2 infection at the time of delivery and 92 had recovered from the infection. There was no statistically significant between-group difference in mean gestational age at delivery (39 weeks for both, p = 0.71) and overall rate of cesarean delivery (26.2% vs 17.4%, respectively, p = 0.35) or non-elective cesarean delivery (10.71% vs 4.34%, respectively, p = 0.48). In the active-infection group, the rate of severe disease was 2.4%, and of critical disease (with intensive care unit admission, mechanical ventilation, and ECMO), 3.6%, compared to zero for both in the recovered group. No differences were found between the groups in adverse perinatal outcomes. CONCLUSION: Delivery is safe and feasible in women with active SARS-CoV-2 infection. Nevertheless, we found a non-significant trend for more severe disease and for cesarean delivery and urgent cesarean delivery (for COVID-19-related indications) in women with an intrapartum SARS-CoV-2 infection.

RESUMO

OBJECTIVE: To compare perinatal outcomes following induction of labor in dichorionic versus monochorionic twin pregnancies. STUDY DESIGN: A retrospective cohort study analyzing all women with twin pregnancies who underwent induction of labor in a single university-affiliated tertiary medical center. The cohort included 290 women who were divided into 2 groups according to chorionicity: (1) dichorionic twin pregnancies (n = 203); (2) monochorionic twin pregnancies (n = 87). Induction of labor methods included oxytocin infusion, extra-amniotic balloon catheter and artificial amniotomy. Primary outcome was defined as mode of delivery. Secondary outcomes included maternal and neonatal adverse events. RESULTS: Primary outcome did not differ between groups, with vaginal delivery rate of 92.1% in the dichorionic group and 94.2% in the monochorionic group. Women with dichorionic twins delivered later compared to monochorionic twins (38.00 weeks vs. 36.43 weeks, respectively, p < 0.001). While no differences were observed in Apgar scores or umbilical cord pH measurements, dichorionic twins were less frequently admitted to the neonatal intensive care unit compared to monochorionic twins (2.4% vs. 3.4%, p = 0.01 for 1st twin; and 6.9% vs. 10.3%, p = 0.089 for 2nd twin). Multivariate logistic regression adjusting outcomes to potential confounders, found gestational age at delivery to be the only variable significantly associated with neonatal intensive care unit admission rates (odds ratio 0.236, 95% confidence interval 0.152-0.366, p < 0.001). CONCLUSION: Labor induction might be considered for both di- and monochorionic uncomplicated twin pregnancies with excellent vaginal delivery rates. The higher rates of neonatal adverse outcomes among monochorionic twins are presumably related to earlier gestation age at delivery.

RESUMO

BACKGROUND: In utero Cytomegalovirus (CMV) vertical transmission occurs predominantly during primary maternal infection. There are no known non-invasive methods for diagnosis of fetal infection before delivery, however some risk factors have been suggested. We aimed to evaluate the association between maternal CMV urinary excretion and congenital CMV infection. METHODS: A retrospective cohort study of all women who were diagnosed with primary CMV infection during pregnancy in a single university affiliated tertiary medical center, between 2012 and 2016. We examined congenital CMV infection and disease rates among infants born to women with and without CMV urinary excretion. RESULTS: Overall, 126 women were included, 77 in the positive urinary excretion group, and 49 in the negative urinary excretion group. There was no difference in maternal symptoms between the groups. We found no difference in congenital CMV infection and disease rates between infants born to women with and without urinary excretion of CMV (congenital infection rate 37.1% vs. 24.4%, p = 0.209, congenital disease rate of 18.2% vs. 22.4%, p = 0.648). Women with positive urinary CMV excretion had lower IgG avidity values (36.7% vs 54.6%, p = 0.007), with no additional difference in serology pattern. Compared to asymptomatic women, those with CMV related symptoms did not have significantly higher rates of urinary excretion of CMV (70% vs. 60.5%, p = 0.38) or congenital infection rates (40.7% vs. 31.2%, p = 0.48). CONCLUSION: Among infants of women with primary CMV infection in pregnancy, we did not find an association between urinary excretion of CMV and congenital CMV infection.

RESUMO

PURPOSE: To evaluate whether antenatal corticosteroids (ACS) administration during the late-preterm (LPT) period in twin pregnancies is associated with decreased rate of neonatal morbidity. METHODS: A retrospective cohort study including a total of 290 women with twin pregnancies resulting in live births of 580 neonates who delivered during LPT period between 2016 and 2018 at a tertiary medical center. Patients were allocated into two groups according to ACS exposure. Obstetric and neonatal outcomes were compared between the groups. Primary outcome was neonatal composite respiratory morbidity, defined as the occurrence of at least one of the followings: RDS, TTN, O2 requirement, CPAP use or mechanical ventilation. RESULTS: Patients exposed to ACS were older and more commonly complicated by gestational diabetes compared to the non-exposed group. Moreover, women exposed to ACS delivered earlier (35.6 vs. 36.3 weeks, P < 0.001) and more frequently by cesarean section (76.4% vs. 54.1%, P = 0.002) compared to the non-exposed group. The rate of composite respiratory morbidity did not differ between the groups. Nevertheless, neonates exposed to ACS had higher rates of neonatal intensive care unit (NICU) admission and hypoglycemia compared to neonates without prior ACS exposure (27.8% vs. 11.7%, P = 0.001; 49.3% vs. 27.1%, P < 0.001, respectively). Multivariable logistic regression revealed that gestational age at delivery was the sole independent risk factor for NICU admission, whereas late-preterm ACS exposure was the only risk factor for hypoglycemia. CONCLUSION: LPT-ACS administration in twin pregnancies complicated by LPT birth in our study did not reduce neonatal respiratory morbidity but was associated with higher rates of hypoglycaemia.

RESUMO

PURPOSE: Prompted by the clinical concern that limited healthcare resources allocation affects physicians' research productivity, this study examines the association between bibliometric indices of ophthalmologic research and national economic indicators in Organisation for Economic Co-operation and Development (OECD) countries. METHODS: The Scimago Journal and Country rank source was searched for research productivity data in ophthalmology among OECD countries between 1996 and 2019. Bibliometric indices included: documents number, number and percent of citable documents, citations number, citations per document, and H-index. The updated economic indicators of each country (gross domestic product [GDP] per capita, health spending as percent of GDP (health expenditure), gross domestic expenditure on research, and development as percent of GDP [GERD]) were collected from the World Bank and the OECD websites. Correlation between economic and bibliometric metrics and multivariate linear regression analyses were performed. RESULTS: Among 267,444 documents analyzed, correlation analysis found a strong correlation between health expenditure and H index (r = 0.711, p < 0.001); a moderate correlation between health expenditure and documents number (r = 0.589, p < 0.001), number of citable document (r = 0.593, p < 0.001) and citations number (r = 0.673, p < 0.001); and a moderate correlation between GERD and H index (r = 0.564, p < 0.001). Multivariate regression analysis controlling for economic factors, population and language showed the independent association of these parameters with bibliometric indices. CONCLUSIONS: This study demonstrates a positive correlation between bibliometric indicators of ophthalmology research and economic factors, particularly health expenditure, among the OECD countries. Our results suggest an advantage of domestic investment in health to expand academic productivity in the field of ophthalmology.

RESUMO

Objective: The objective was to examine the association between poor ovarian response to gonadotropin stimulation for in vitro fertilization (IVF) and adverse perinatal outcomes in singleton gestations in young patients. Methods: This was a retrospective cohort study including women aged 17-39 who underwent fresh embryo transfer and delivered a singleton neonate at a single center (pre-implantation genetic testing excluded) (2007-2022). Patients were classified as one of the following categories: poor responders-daily follicle-stimulating hormone (FSH) ≥ 150 IU yielding ≤ 3 retrieved oocytes; normal responders-4-15 oocytes; and high responders with ≥16 oocytes. The primary outcome was a composite of pre-eclampsia (mild or severe), small-for-gestational-age, gestational diabetes mellitus, and preterm birth (<37 weeks). We compared maternal and neonatal outcomes between the three groups. Multivariable logistic regression was used to control for confounders. Results: Overall, 507 women met the inclusion criteria. Of them, there were 44 (8.68%) poor responders, 342 (67.46%) normal responders, and 121 (23.87%) high responders. Poor responders, compared to normal and high responders, were characterized by a higher maternal age (34.64 ± 4.01 vs. 31.4 ± 5.04 vs. 30.01 ± 4.93, p < 0.001, respectively) and total FSH dosage (3028.41 ± 1792.05 IU vs. 2375.11 ± 1394.05 IU vs. 1869.31 ± 1089.63 IU, p < 0.001). The perinatal outcomes examined, including cesarean delivery (CD) rate and the composite outcome, were comparable between groups. Using multivariable logistic regression and adjusting for ovarian response group, maternal age, nulliparity, and estradiol level and endometrial thickness before ovulation triggering, poor response was not associated with CD rate or the composite outcome, with maternal age associated with CD (p = 0.005), and nulliparity with the composite outcome (p = 0.007). Similar results were obtained when comparing poor responders to each other group separately or to all other responders. Conclusions: Poor ovarian response is not associated with increased adverse maternal or neonatal outcomes.

RESUMO

PURPOSE: To recognize prognostic factors for better final visual acuity (VA) in patients presenting with submacular hemorrhage (SMH) secondary to exudative age-related macular degeneration. METHODS: This retrospective study included patients who presented to a tertiary ophthalmology department between 2012 and 2019 with SMH and were treated by pars plana vitrectomy (PPV) or injection of tissue plasminogen activator (tPA) with pneumatic displacement. Baseline characteristics included demographic data, VA and optical coherence tomography (OCT) characteristics of the SMH. Patients were divided into groups by improvement of at least 2 lines in BCVA (best corrected visual acuity), and by having a final BCVA better than 20/200. RESULTS: Forty-three eyes of 43 patients were included. Mean age was 86.72 ± 7.18. Prognostic factors for final VA better than 20/200 included better VA at presentation (1.25 vs 1.90 logMAR, p < 0.001), smaller area of SMH in the infra-red image (19.47 mm2 vs 38.45 mm2, p = 0.024), and lower height of SMH as measured by OCT (713.5 µm vs 962.5 µm, p = 0.03). Third of the patients improved in ≥2 lines from presentation, all in the group of the pneumatic and TPA displacement. CONCLUSION: Smaller SMHs with good VA at presentation have a better chance for improvement and result in a better final VA. These patients may benefit the most from pneumatic displacement of the SMH with intravitreal tPA and gas.

RESUMO

BACKGROUND: The number of nulliparous women over the age of 35 is consistently increasing, and the optimal delivery strategy is a subject of ongoing discussion. This study compares perinatal outcomes in nulliparous women aged ≥35 years undergoing a trial of labor (TOL) versus a planned cesarean delivery (CD). METHODS: A retrospective cohort study including all nulliparous women ≥ 35 years who delivered a single term fetus at a single center between 2007-2019. We compared obstetric and perinatal outcomes according to mode of delivery-TOL versus a planned CD, in three different age groups: (1) 35-37 years, (2) 38-40 years, and (3) >40 years. RESULTS: Out of 103,920 deliveries during the study period, 3034 women met the inclusion criteria. Of them, 1626 (53.59%) were 35-37 years old (group 1), 848 (27.95%) were 38-40 (group 2), and 560 (18.46%) were >40 years (group 3). TOL rates decreased as age increased: 87.7% in group 1, 79.3% in group 2, and 50.1% in group 3, p < 0.001. Rates of successful vaginal delivery were 83.4% in group 1, 79.0% in group 2, and 69.4% in group 3, p < 0.001). Neonatal outcomes were comparable between a TOL and a planned CD. Using multivariate logistic regression, maternal age was found to be independently associated with slightly increased odds for a failed TOL (aOR = 1.13, CI 95% 1.067-1.202). CONCLUSIONS: A TOL at advanced maternal age appears to be safe, with considerable success rates. As maternal age advances, there is a small additive risk of intrapartum CD.

RESUMO

PURPOSE: To compare the accuracy of the Barrett Integrated K (IK) toric calculator with the standard Barrett toric calculator. METHODS: Consecutive patients who underwent cataract extraction with implantation of a toric intraocular lens at the Rabin Medical Center, Israel, were reviewed. Errors in predicted postoperative refractive astigmatism were calculated for the Barrett toric calculator using biometry measurements only and with the IK tool using biometry and tomography. Both methods were assessed with predicted and measured posterior corneal astigmatism (PPCA and MPCA, respectively). RESULTS: The study included 73 eyes of 59 patients. The mean centroid prediction error using PPCA (0.08 ± 0.80 D @ 78°) was significantly different compared with MPCA (0.07 ± 0.80 D @ 48°, P = .016). In addition, a significant difference between IK-PPCA (0.06 ± 0.80 D @ 80°) and IK-MPCA (0.05 ± 0.80 D @ 38°) was found (P = .023). The median absolute prediction error ranged from 0.55 D using IK-PPCA to 0.60 D using PPCA, with no significant differences between the four calculation versions. No significant differences were found between the calculators in the predictability rates within ±0.50, ±0.75, and ±1.00 D. Analysis of one eye of each patient showed similar results. CONCLUSIONS: The IK calculator yielded comparable outcomes to the standard Barrett calculator. Although differences in the mean centroid errors were found, they were clinically insignificant and predominantly seen in the axis of the predicted astigmatism error. These minor differences were mainly attributed to the incorporation of the MPCA in the calculation. [J Refract Surg. 2022;38(9):565-571.].

RESUMO

The course of COVID-19 has been shown to be worse in pregnant women compared with their non-pregnant counterparts. The aim of this study is to share our experience treating pregnant women with COVID-19 and to establish a cohort for future studies of the long-term effects of the disease. We reviewed medical records of all SARS-CoV-2-positive pregnant women who were treated at our hospital for any reason, be it COVID-19 related or not, between April 2020 and February 2021. We extracted data regarding medical history, course of pregnancy, delivery, and neonatal outcomes. A total of 193 SARS-CoV-2-positive pregnant women were treated at our establishment during the study period, half of which were asymptomatic. Sixteen were hospitalized for COVID-19 symptoms, the most common being fatigue/malaise (58%) and cough (48%). Three women required mechanical ventilation and extracorporeal membrane oxygenation treatment. One hundred forty-four SARS-CoV-2-positive women were delivered during the study period. Of them, 24 (17%) underwent induction of labor, and four (17%) were due to symptomatic COVID-19. One hundred fifteen (80%) experienced vaginal delivery, and 29 (20%) underwent cesarean delivery. Neonatal outcomes were favorable; only 2% of 5-min Apgar scores were < 7, and all umbilical cord pH levels were > 7.1. Six infants tested positive for SARS-CoV-2; they were all asymptomatic, and none required treatment for viral infection. COVID-19 during pregnancy is a disease with potential substantial adverse maternal and neonatal outcomes. There is still much unknown regarding the long-term effects of the disease on parturients and their offspring.

RESUMO

A novel coronavirus termed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a new strain of coronavirus causing coronavirus disease 2019 (COVID-19) disease, which emerged as a global pandemic. Data regarding the implications of COVID-19 disease at early gestation on fetal and obstetric outcomes is scarce. Thus, our aim was to investigate the effect of first and second trimester maternal COVID-19 disease on fetal and perinatal outcomes. This was a prospective cohort study of pregnant women with a laboratory-proven SARS-COV-2 infection contracted prior to 26 weeks gestation. Women were followed at a single tertiary medical center by serial sonographic examinations every 4-6 weeks to assess fetal well-being, growth, placental function, anatomic evaluation and signs of fetal infection. Amniocentesis was offered to assess amniotic fluid SARS-COV-2-PCR (polymerase chain reaction) and fetal brain magnetic resonance imaging (MRI) was offered at 30-32 weeks gestation. Demographic, obstetric and neonatal data were collected from history intake, medical charts or by telephone survey. Perinatal outcomes were compared between women infected at first vs. second trimester. 55 women with documented COVID-19 disease at early gestation were included and followed at our center. The mean maternal age was 29.6 ± 6.2 years and the mean gestational age at viral infection was 14.2 ± 6.7 weeks with 28 (51%) women infected at the first trimester and 27 (49%) at the second trimester. All patients but one experienced asymptomatic to mild symptoms. Of 22 patients who underwent amniocentesis, none had evidence of vertical transmission. None of the fetuses exhibited signs of central nervous system (CNS) disease, growth restriction and placental dysfunction on serial ultrasound examinations and fetal MRI. Pregnancies resulted in perinatal survival of 100% to date with mean gestational age at delivery of 38.6 ± 3.0 weeks and preterm birth <37 weeks rate of 3.4%. The mean birthweight was 3260 ± 411 g with no cases of small for gestational age infants. The obstetric and neonatal outcomes were similar among first vs. second trimester infection groups. We conclude SARS-CoV-2 infection at early gestation was not associated with vertical transmission and resulted in favorable obstetric and neonatal outcomes.
