RESUMO

AIMS: To evaluate the coronavirus disease 2019 pandemic's impact on pregnancy outcomes in a Japanese rural area. METHODS: This retrospective study focused on the periods between March 1, 2020, and February 28, 2021 (during the coronavirus disease 2019 pandemic), and January 1, 2017, and December 31, 2019. Singleton pregnancies delivered at or after 22 gestational weeks were included. Preterm delivery, low-birth-weight, and small-for-gestational-age infant rates during the pandemic were compared to those in the preceding 3 years. RESULTS: In the pandemic and control groups, 1650 and 5762 pregnant women were included, respectively. Two pregnant women with coronavirus disease 2019 were identified (0.1%). There were no significant intergroup differences in preterm delivery rates (control, 4% vs. pandemic, 3.3%; difference: -0.7% [95% confidence interval: -1.7%-0.3%], p = 0.22). The low-birth-weight rate tended to decrease; however, the difference was insignificant (7.9% vs. 6.5%; difference: -1.4% [95% confidence interval: -2.8-0%], p = 0.06). The small-for-gestational-age infant rate was significantly lower in the pandemic than in the control group (7.3% vs. 5.2%; difference: -2.1% [95% confidence interval: -3.3-0.8%], p < 0.01). However, the interrupted time series analysis showed no significant trend. CONCLUSIONS: There were no significant changes in the rates of preterm delivery, low-birth-weight infants, and small-for-gestational-age infants during the pandemic's first year compared to those in the preceding 3 years. Behavioral changes, such as "stay-at-home" measures, may not improve pregnancy outcomes in Japan.

RESUMO

AIMS: Magnesium sulfate has neuroprotective effects in preterm infants. Whether other antepartum treatments interfere with the neuroprotective actions is not well known. This study aims to explore the impacts of antenatal administration of Magnesium sulfate or beta-2 adrenergic agonists as tocolytic agents on the developing brain in premature infants. METHODS: This is a retrospective cohort study in four tertiary perinatal centers in Japan. We collected data of pregnant women and infants born between 28 and 36 weeks for tocolytic agents, gestational age, sex, antenatal corticosteroid, fetal growth restriction, pathological chorioamnionitis, low umbilical arterial pH values (<7.1), multiple pregnancy, mode of delivery and institutions after excluding clinical chorioamnionitis, non-reassuring fetal status or major anomalies. Tocolytic agents were categorized into four groups: no-tocolysis, magnesium sulfate, beta-2 adrenergic agonists and the combination of them. We conducted multiple comparisons with multivariate analyses using generalized linear regression models to compare the prevalence of a poor perinatal outcome defined as infant's death, brain damage, particularly cerebral palsy and developmental delay. RESULTS: Among 1083 infants, 39% were no-tocolysis, 47% were magnesium sulfate, 41% were beta-2 adrenergic agonists and 27% were combination group, including the duplication. The incidence of poor perinatal outcome was decreased by magnesium sulfate (OR 0.27, 95% CI 0.10-0.72), but not changed significantly by beta-2 adrenergic agonists (OR 1.28, 95% CI 0.63-2.59) or the combination group (OR 2.24, 95% CI 0.67-7.54), compared with the no-tocolysis. CONCLUSION: The combination therapy for tocolysis with beta-2 adrenergic agonists diminished the magnesium sulfate neuroprotective action after adjusting for covariables.

RESUMO

AIM: To investigate the effects of Mycoplasma/Ureaplasma cultured in amniotic fluid on perinatal characteristics in preterm delivery between 22 and 33 weeks of gestation. METHODS: The study was conducted in a tertiary perinatal center and involved 38 pregnant women who had undergone amniocentesis to evaluate intrauterine infection due to preterm labor or premature rupture of membranes. The subjects were divided into three groups based on the culture results: negative (Negative Group, n = 24), positive for Mycoplasma/Ureaplasma (M/U Group, n = 6), and positive for other pathogens (Other Pathogens Group, n = 8). One-way analysis of variance was used to compare the three groups. RESULTS: The incidence of histological chorioamnionitis and neonatal sepsis was significantly different among the three groups (the Negative Group and the Other Pathogens Group, P < 0.01; the M/U Group and the Other Pathogens Group, P = 0.03). In the M/U Group, no infants had sepsis, severe intraventricular hemorrhage, cystic periventricular leukomalacia, or poor neurological outcomes, but one infant developed bronchopulmonary dysplasia and needed home oxygen treatment. Although one died of gastrorrhexis, the remaining five patients had normal brain magnetic resonance imaging findings and developed normally. CONCLUSION: The presence of Mycoplasma/Ureaplasma isolated from amniotic fluid did not cause neonatal sepsis or poor prognosis. In some infants, there was no histological chorioamnionitis in the placenta. These pathogens thus seem to be less invasive than any other microbes with respect to perinatal outcomes.

RESUMO

Fetoscopic laser photocoagulation (FLP) of placental anastomoses is a well-established procedure for twin-to-twin transfusion syndrome that improves fetal outcome with rare maternal complications. However, fetal hydrops can develop even after FLP, and mirror syndrome can occur, indicating that both the fetal and maternal courses should be monitored after FLP.

RESUMO

We conducted a questionnaire survey on the current obstetric management of preterm labor (PL) and preterm premature rupture of the membranes (pPROM). The questionnaire covered approximately a third of all preterm deliveries and nearly half of the preterm deliveries before 32 gestational weeks. The diagnostic criterion for PL was either painful uterine contractions or cervical dilatation. Tocolytic agents were primarily used as long-term maintenance therapy. Intrauterine infection was clinically diagnosed at most responding institutions. Amniocentesis was performed for PL or pPROM at only a small number (10%) of institutions. Prenatal steroids were administered for PL or pPROM, if indicated, at approximately 40-60% of responding institutions. Prophylactic antibiotics to maintain pregnancy were administered for pPROM at approximately 90% and for PL at approximately 20% of institutions. Maintenance therapy with a tocolytic agent was used for pPROM at approximately 90% of institutions.

RESUMO

Helicobacter cinaedi is a rare pathogen but known to cause bacteremia, cellulitis and enterocolitis. Recently, cases of involving various organs are increasingly reported such as endocarditis, meningitis, and kidney cyst infection. We report a case of intrauterine H. cinaedi infection leading preterm birth and neonatal sepsis. A 29-year-old pregnant women who was no underlying disease hospitalized due to threatened preterm labor at 22 weeks of gestation. Clinical findings showed uterine tenderness, fever, leukocytosis and elevated C-reactive protein. H. cinaedi was isolated from amniotic fluid obtained by transabdominal amniocentesis. We diagnosed as intrauterine H. cinaedi infection and administered intravenous ampicillin followed by oxytocin to terminate pregnancy. A live 446 g male infant was delivered. The patient was no signs of infection throughout postpartum course and discharged on post-delivery day 5. The neonate was admitted in neonatal intensive care unit and administered ampicillin and amikacin. H. cinaedi was isolated from umbilical cord blood culture. He has no signs of infection on day 5 but died from uncontrollable hyperglycemia and ketoacidosis on 15 days of age. H. cinaedi can cause intrauterine infection during pregnancy and lead preterm labor and neonatal sepsis.
