Limited data are available on pregnant women with COVID-19 and their neonates. We aimed to evaluate the epidemiological and clinical characteristics of newborns born to women infected with COVID-19. A multicenter cohort study was conducted among newborns born to mothers with COVID-19 in 34 neonatal intensive care units (NICUs) in Turkey. Pregnant women ( n = 125) who had a positive RT-PCR test and their newborns were enrolled. Cesarean section, prematurity, and low-birthweight infant rates were 71.2%, 26.4%, and 12.8%, respectively. Eight of 125 mothers (6.4%) were admitted to an intensive care unit for mechanical ventilation, among whom six died (4.8%). Majority of the newborns (86.4%) were followed in isolation rooms in the NICU. Four of 120 newborns (3.3%) had a positive RT-PCR test result. Although samples taken on the first day were negative, one neonate became positive on the second day and the other two on the fifth day. Sample from deep tracheal aspirate was positive on the first day in an intubated case. Conclusion : COVID-19 in pregnant women has important impacts on perinatal and neonatal outcomes. Maternal mortality, higher rates of preterm birth and cesarean section, suspected risk of vertical transmission, and low rate of breastfeeding show that family support should be a part of the care in the NICU. Trial registration : ClinicalTrials.gov identifier: NCT04401540 What is Known: • The common property of previous reports was the conclusions on maternal outcomes, rather than neonatal outcomes. • Published data showed similar outcomes between COVID-19 pregnant women and others. What is New: • Higher maternal mortality, higher rates of preterm birth and cesarean section, suspected risk of vertical transmission especially in a case with deep tracheal aspiration during the intubation, and the possible role of maternal disease severity on the outcomes are remarkable findings of this study. • In contrast to recommendation for breastfeeding, parents’ preference to formula and expressed breast milk due to anxiety and lack of information shows that family support should be a part of the care in the NICU.

Arthrogryposis–renal dysfunction–cholestasis (ARC) syndrome is a rare autosomal recessive multisystem disorder caused by mutations in vacuolar protein sorting 33 homologue B (VPS33B) and VPS33B interacting protein, apical–basolateral polarity regulator (VIPAR). Cardinal features of ARC include congenital joint contractures, renal tubular dysfunction, cholestasis, severe failure to thrive, ichthyosis, and a defect in platelet alpha-granule biogenesis. Most patients with ARC do not survive past the first year of life. We report two patients presenting with a mild ARC phenotype, now 5.5 and 3.5 years old. Both patients were compound heterozygotes with the novel VPS33B donor splice-site mutation c.1225+5G>C in common. Immunoblotting and complementary DNA analysis suggest expression of a shorter VPS33B transcript, and cell-based assays show that c.1225+5G>C VPS33B mutant retains some ability to interact with VIPAR (and thus partial wild-type function). This study provides the first evidence of genotype–phenotype correlation in ARC and suggests that VPS33B c.1225+5G>C mutation predicts a mild ARC phenotype. We have established an interactive online database for ARC (https://grenada.lumc.nl/LOVD2/ARC) comprising all known variants in VPS33B and VIPAR. Also included in the database are 15 novel pathogenic variants in VPS33B and five in VIPAR. Hum Mutat 33:1656–1664, 2012. © 2012 Wiley Periodicals, Inc.

Hospital type and country socioeconomic level influence DA-HAI rates and overall mortality in developing countries.

Design. Before-after prospective surveillance study to assess the efficacy of the International Nosocomial Infection Control Consortium (INICC) multidimensional infection control program to reduce the rate of occurrence of ventilator-associated pneumonia (VAP). Setting. Neonatal intensive care units (NICUs) of INICC member hospitals from 15 cities in the following 10 developing countries: Argentina, Colombia, El Salvador, India, Mexico, Morocco, Peru, Philippines, Tunisia, and Turkey. Patients. NICU inpatients. Methods. VAP rates were determined during a first period of active surveillance without the implementation of the multidimensional approach (phase 1) to be then compared with VAP rates after implementation of the INICC multidimensional infection control program (phase 2), which included the following practices: a bundle of infection control interventions, education, outcome surveillance, process surveillance, feedback on VAP rates, and performance feedback on infection control practices. This study was conducted by infection control professionals who applied National Health Safety Network (NHSN) definitions for healthcare-associated infections and INICC surveillance methodology. Results. During phase 1, we recorded 3,153 mechanical ventilation (MV)-days, and during phase 2, after the implementation of the bundle of interventions, we recorded 15,981 MV-days. The VAP rate was 17.8 cases per 1,000 MV-days during phase 1 and 12.0 cases per 1,000 MV-days during phase 2 (relative risk, 0.67 [95% confidence interval, 0.50-0.91]; [Formula: see text]), indicating a 33% reduction in VAP rate. Conclusions. Our results demonstrate that an implementation of the INICC multidimensional infection control program was associated with a significant reduction in VAP rate in NICUs in developing countries.

Late-preterms have significantly higher risk of morbidity and mortality compared with term newborns. Greater concern and attention is required for the care of this ignored, at-risk population.

None of the preterm infants in this study had normal vitamin D level, which underlined the burden of vitamin D deficiency in pregnant women and their offspring. RDS was more common in severely vitamin D-deficient preterms. Determination of vitamin D status of the mothers and appropriate supplementation might be a valuable strategy to reduce RDS, in addition to antenatal steroids. Besides, since vitamin D is a regulatory factor in many organs during fetal development, long-term effects of in utero vitamin D deficiency warrant further studies.
