Depressive symptoms in mothers of preterm infants before and during COVID-19 restrictions in neonatal intensive care units.

AIM: Little is known about the specific restriction measures used in intensive care units (NICUs) during the COVID-19 pandemic and their impact on parental well-being. Hence, this study aimed to assess the association between restriction measures and mothers' post-partum depressive symptoms. METHODS: This comparative cohort study included mothers who gave birth before 35 weeks of gestation in Estonia. The outcome measure was mothers' post-partum depressive symptoms at the time of infant discharge, evaluated using the Edinburgh Postnatal Depression Scale (EPDS). In addition to the pandemic itself, the number of restriction measures in the NICUs was analysed as a potential explanatory factor for depressive symptoms. RESULTS: The study included 55 mothers before the pandemic in 2018-2019 and 54 mothers during the COVID-19 pandemic in 2021. No significant difference was found in the median EPDS scores between the cohorts: 7.0 [interquartile range (IQR): 4.0-12.0] and 8.0 (IQR: 5.0-12.8) respectively. The number of restriction measures was not associated with mothers' EPDS scores in either unadjusted or adjusted models. CONCLUSION: The COVID-19 pandemic or the number of restriction measures used in Estonian NICUs did not associate with mothers' post = partum depressive symptoms.

Changes in care and short-term outcome for very preterm infants in Estonia.

AIM: To identify recent changes in short-term outcome and care for very preterm infants in Estonia. METHODS: Comparison of two population-based cohort of very preterm infants born alive at 22-31 gestational weeks. In 2007-2008, data were recorded prospectively in a neonatal register. For the cohort born in 2002-2003, the same variables were extracted retrospectively from the hospital records. Infants were followed up to discharge or death. RESULTS: The cohort of 2007-2008 contained a higher proportion of infants born by caesarean section and of infants who received antenatal corticosteroids, maternal antibiotics, or surfactant therapy than the earlier cohort. A higher proportion of infants was admitted for care in 2007-2008 (98% vs. 94%; p = 0.013). During the study period, survival until discharge increased (85% vs. 78%; p = 0.041), although the length of hospital stay was unchanged. The use of mechanical ventilation, inotropes, and postnatal antibiotics decreased. Neonatal morbidity remained unchanged, except for a decrease in severe periventricular/intraventricular haemorrhage. CONCLUSION: The outcome for very preterm infants in Estonia has improved since 2002. With proactive perinatal management and less invasive neonatal care, survival until discharge increased without concomitant increases in neonatal morbidity and the length of hospital stay.

Hospitalisation of late preterm infants due to lower respiratory tract infections in Lithuania, Latvia, and Estonia: incidence, disease severity, and risk factors.

BACKGROUND: By two years of age, almost all children experience at least one episode of respiratory syncytial virus (RSV) infection, the most common viral cause of hospitalisation due to lower respiratory tract infection (LRTI). We present data on LRTI hospitalisations (with a special focus on RSV), the course of illness, and LRTI hospitalisation risk factors in Lithuania, Latvia, and Estonia. MATERIALS AND METHODS: The analysed data were part of a large multinational study conducted in 23 countries (PONI). LRTI-related hospitalisations were observed during one RSV season for late premature infants (born between 33 weeks and 0 days and 35 weeks and 6 days of gestation) ≤6 months of age, who did not receive RSV prophylaxis. The potential risk factors and demographics were recorded at study enrolment and at the end of the RSV season. The primary endpoint was hospitalisation due to RSV LRTI; the secondary endpoints included severity, the course and the outcome of LRTI hospitalisations. RESULTS: Out of the 291 infants enrolled in three Baltic states, 19 were hospitalised due to LRTI (6.5%). RSV testing was performed for 14 hospitalised infants; five infants had a positive test for RSV (1.7%). The majority of the hospitalised infants (94.7%) had mild or moderate respiratory illness. Male sex, O2 dependency after birth, younger maternal age, and furred pets at home were significantly associated with an increased risk for LRTI hospitalisation. CONCLUSIONS: During one RSV season, the incidence of LRTI hospitalisations among late preterm infants was 6.5% and the incidence of RSV LRTI hospitalisations was 1.7%.
