Perinatal mortality and morbidity is markedly increased in intrauterine growth restricted (IUGR) fetuses. Prenatal identification of IUGR is the first step in clinical management. For that purpose a uniform definition and criteria are required. The etiology of IUGR is multifactorial and whenever possible it should be assessed. When the cause is of placental origin, it is possible to identify the affected fetuses. The major complication is chronic fetal hypoxemia. By monitoring the changes of fetal vital functions it is thus possible to improve both management and outcome. The timing of delivery is crucial but the optimal management scheme has not yet been identified. When IUGR is identified at very early gestational ages, serial assessments of the risk of continuing the in utero fetal life under adverse conditions versus the risks of the prematurity should be performed. Delivery of IUGR fetuses should take place in centers where appropriate neonatal *This paper was produced under the auspices of the WAPM for a consensus on issues in perinatal practice, coordinated by Giampaolo Mandruzzato, MD. **Corresponding author: Giampaolo Mandruzzato, MD Via del Lazzaretto vecchio 9 34132 Trieste Italy E-mail: mandruzzatogiampaolo@tin.it assistance can be provided. Careful monitoring of the IUGR fetus during labor is crucial as the IUGR fetus can quickly decompensate once uterine contractions have started.

ObjectivesTo evaluate the strength of association between maternal and pregnancy characteristics and the risk of adverse perinatal outcomes in pregnancies with laboratory confirmed COVID-19.MethodsSecondary analysis of a multinational, cohort study on all consecutive pregnant women with laboratory-confirmed COVID-19 from February 1, 2020 to April 30, 2020 from 73 centers from 22 different countries. A confirmed case of COVID-19 was defined as a positive result on real-time reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assay of nasal and pharyngeal swab specimens. The primary outcome was a composite adverse fetal outcome, defined as the presence of either abortion (pregnancy loss before 22 weeks of gestations), stillbirth (intrauterine fetal death after 22 weeks of gestation), neonatal death (death of a live-born infant within the first 28 days of life), and perinatal death (either stillbirth or neonatal death). Logistic regression analysis was performed to evaluate parameters independently associated with the primary outcome. Logistic regression was reported as odds ratio (OR) with 95% confidence interval (CI).ResultsMean gestational age at diagnosis was 30.6±9.5 weeks, with 8.0% of women being diagnosed in the first, 22.2% in the second and 69.8% in the third trimester of pregnancy. There were six miscarriage (2.3%), six intrauterine device (IUD) (2.3) and 5 (2.0%) neonatal deaths, with an overall rate of perinatal death of 4.2% (11/265), thus resulting into 17 cases experiencing and 226 not experiencing composite adverse fetal outcome. Neither stillbirths nor neonatal deaths had congenital anomalies found at antenatal or postnatal evaluation. Furthermore, none of the cases experiencing IUD had signs of impending demise at arterial or venous Doppler. Neonatal deaths were all considered as prematurity-related adverse events. Of the 250 live-born neonates, one (0.4%) was found positive at RT-PCR pharyngeal swabs performed after delivery. The mother was tested positive during the third trimester of pregnancy. The newborn was asymptomatic and had negative RT-PCR test after 14 days of life. At logistic regression analysis, gestational age at diagnosis (OR: 0.85, 95% CI 0.8–0.9 per week increase; p<0.001), birthweight (OR: 1.17, 95% CI 1.09–1.12.7 per 100 g decrease; p=0.012) and maternal ventilatory support, including either need for oxygen or CPAP (OR: 4.12, 95% CI 2.3–7.9; p=0.001) were independently associated with composite adverse fetal outcome.ConclusionsEarly gestational age at infection, maternal ventilatory supports and low birthweight are the main determinants of adverse perinatal outcomes in fetuses with maternal COVID-19 infection. Conversely, the risk of vertical transmission seems negligible.

Despite the increasing number of published studies, objective evidence is still needed to draw any conclusion on the course of SARS-COV-2 infection acquired during pregnancy. What are the clinical implications of this work? The study showed that in pregnancies complicated by SARS-COV-2, the risk of maternal mortality was 0.8%, but about 11% of women required admission to ICU. Pregnancies affected by SARS-COV-2 were also complicated by 23% rate preterm birth, and 4.1% rate of perinatal death. The risk of vertical transmission was negligible.

BACKGROUND: Moderate hypothermia (temperature ,36°C) at birth is common in premature infants and is associated with increased mortality and morbidity.METHODS: A multidisciplinary practice plan was implemented to determine in premature infants ,35 weeks old whether a multifaceted approach would reduce the number of inborn infants with an admitting axillary temperature ,36°C by 20% without increasing exposure to a temperature .37.5°C. The plan included use of occlusive wrap a transwarmer mattress and cap for all infants and maintaining an operating room temperature between 21°C and 23°C. Data were obtained at baseline (n = 66), during phasing in (n = 102), and at full implementation (n = 193).RESULTS: Infant axillary temperature in the delivery room (DR) increased from 36.1°C 6 0.6°C to 36.2°C 6 0.6°C to 36.6°C 6 0.6°C (P , .001), and admitting temperature increased from 36.0°C 6 0.8°C to 36.3°C 6 0.6°C to 36.7°C 6 0.5°C at baseline, phasing in, and full implementation, respectively (P , .001). The number of infants with temperature ,36°C decreased from 55% to 6.2% at baseline versus full implementation (P , .001), and intubation at 24 hours decreased from 39% to 17.6% (P = .005). There was no increase in the number of infants with a temperature .37.5°C over time. The use of occlusive wrap, mattress, and cap increased from 33% to 88% at baseline versus full implementation. Control charts showed significant improvement in DR ambient temperature at baseline versus full implementation. CONCLUSIONS:The practice plan was associated with a significant increase in DR and admitting axillary infant temperatures and a corresponding decrease in the number of infants with moderate hypothermia. There was an associated reduction in intubation at 24 hours. These positive findings reflect increased compliance with the practice plan.
