Respiratory problems in full term newborns, which parameters are related to the length of in-patient stay?

OBJECTIVE: To analyze respiratory problems of full term newborn babies during their first hours of life, compare parameters related to the length of neonatal intensive care unit (NICU) in-patient stay, and discuss perinatal care practices, which could prevent consequences, and/or reduce associated costs of NICU hospitalization. MATERIAL AND METHODS: Retrospective chart review between July 31st 2017 and March 2nd 2018 in a tertiary maternity hospital. Chi-square testing analyzed qualitative data. Mann-Whitney test was used for quantitative variables. Multiple linear regression models determined odds ratios for associations were found to be significant in univariate analyses. RESULTS: 86 babies with respiratory problems were studied. Delivery mode was vaginal in 11.6% and caesarean section in 88.4% of newborns. About 52.3% of admitted newborns had transient tachypnea and improved relatively quickly. Newborns resuscitated in (P = 0.004) or admitted to the NICU from the delivery room (P = 0.000) displayed greater need for O2 administration. Twenty neonates were intubated; 16 of them were administered surfactant. Infection (P < 0.05), abnormal chest x-ray (P = 0.022), and the severity of respiratory system morbidity (P < 0.05) prolonged neonatal in-patient stay. Respiratory problems (P = 0.003) and intubation (P = 0.032) incurred greater hospitalization costs. Breastfeeding initiation before the 3rd day of life (P = 0.031), and O2 administration for more than 72 h (P = 0.036) were significantly associated with the length of in-patient stay in the multivariate regression analysis. CONCLUSION: Mandating the presence of a pediatrician in the delivery room would optimize justified direct NICU admissions and reduce the possibility of delayed diagnosis of respiratory distress during rooming-in. NICU in-patient stay in full term neonates should be based on combining diagnostic markers of sepsis, such as procalcitonin or interleukin-6. A specific protocol regarding surfactant administration in intubated full term infants is also necessary. The severity of respiratory system morbidity is not the key determinant of infant feeding. Maternal information regarding infant health and breastfeeding abilities may improve breastfeeding rates.

Knowledge, attitudes and practices about vaccine-preventable diseases and vaccinations of children among pregnant women in Greece.

Vaccine hesitancy has been recognized by the World Health Organization as one of ten threats to public health globally in 2019. Pregnant women constitute an extremely important group for the study of knowledge and attitudes towards pediatric vaccinations. This is a cross-sectional survey conducted in two maternity hospitals in Athens. A standardized questionnaire was used. A total of 814 pregnant women with a mean age of 33.1 years and a mean gestational age of 24.4 weeks were studied. Overall, 717 (89%) of 804 pregnant women reported that they intend to vaccinate their baby in accordance with the National Vaccination Program, 7 (1%) that they do not, while 80 (10%) reported that they have not decided yet. The women provided a mean of 11.4 correct replies out of 14 questions about vaccine-preventable diseases and vaccines (mean knowledge score: 81.5%). A pediatrician has been recognized as the source for information about vaccines in most cases (611/809, 75.5%), while in 215 (26.6%) the internet was also used. Overall, pregnant women trusted physicians about information for vaccines ("very much trusted" in 55.9% and "quite trusted" in 40% of cases). Lastly, 642 (81%) women agreed with the statement "vaccinations should be mandatory for school entry" while 70 (9%) women agreed with the statement "parents should have the right to refuse their children vaccinations". A multivariate analysis found that a gestational age of ≤20 weeks (OR = 2.33, CIs: 1.27-4.28, p-value = 0.006), having another child (OR = 4.44, CIs: 2.30-8.58, p-value < 0.001), a history of influenza vaccination (OR = 2.54, CIs = 1.37-4.71, p-value = 0.003), and a higher knowledge score about vaccine-preventable diseases and vaccines (OR = 1.33, CIs: 1.23-1.45, p-value < 0.001) were significantly associated with an increased probability to get their child vaccinated in accordance with the National Vaccination Program.

Neonatal screening for congenital CMV infection stresses the importance of maternal nonprimary infection even in an area where prenatal serology testing is common.

AIM AND METHODS: Dried blood spots from 2149 newborns were examined to diagnose congenital cytomegalovirus (cCMV). RESULTS: Prenatal CMV-IgG antibodies had been measured during prenatal care in 1287 (60.3%) of mothers and 980 (76.1%) of them were found seropositive. cCMV incidence was 0.47%. All newborns were asymptomatic; 9/10 were born post nonprimary maternal infection; two developed sensorineural hearing loss. CONCLUSIONS: In a country where prenatal CMV testing is common and therefore a false sense of control might prevail, nonprimary maternal infection should not be overlooked. Indeed, women of childbearing age should be educated on CMV prevention measures irrespectively to their serostatus.

Effect of Formula Containing Lactobacillus reuteri DSM 17938 on Fecal Microbiota of Infants Born by Cesarean-Section.

OBJECTIVES: Microbiota modulation by probiotics in infants born by cesarean (C)-section is poorly understood. We aimed at assessing the response of C-section-delivered infant microbiota to a formula containing Lactobacillus reuteri Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH (DSM) 17938 and comparing it with that of vaginally delivered infants. METHODS: Infants delivered by C-section (C) and vaginally (V) were randomized to receive either control formula (CCt, n = 10; VCt, n = 10) or the same formula containing L reuteri (CLr, n = 11; VLr, n = 9) within 72 hours following birth. Stool samples were collected at 2 weeks and 4 months of age. Microbial DNA was extracted, amplified, and pyrosequenced. RESULTS: The phylogenetic profiles of the CLr, VCt, and VLr microbiota were not significantly different at any age but diverged from that of CCt at 2 weeks. Compared with VCt, CCt displayed lower Bifidobacterium and higher Enterobacter, unclassified Enterobacteriaceae, Enterococcus, Clostridium, and unclassified Clostridiaceae relative abundance at 2 weeks, as well as lower Collinsella and higher Enterococcus and Coprococcus abundance at 4 months. The level of most of these taxa was not significantly different between the CLr and the vaginal-delivery groups. Compared with VCt, the only difference observed in VLr microbiota was higher Lactobacillus at the 2 study ages and Coprococcus at 4 months. CONCLUSIONS: Our results show that a formula containing L reuteri DSM 17938 does not essentially alter the microbiota in vaginally born infants. In C-section-delivered infants, however, this strain seems to play the role of keystone species by modulating the early development of the microbiota toward the composition found after vaginal delivery.

A Randomized Double Blind Controlled Safety Trial Evaluating d-Lactic Acid Production in Healthy Infants Fed a Lactobacillus reuteri-containing Formula.

BACKGROUND: d-Lactic acidosis in infants fed lactic acid bacteria-containing products is a concern. METHODS: The primary objective of this non-inferiority trial was to compare urinary d-lactic acid concentrations during the first 28 days of life in infants fed formula containing Lactobacillus reuteri (1.2 × 10(6) colony forming units (CFU)/ml) with those fed a control formula. The non-inferiority margin was set at a two-fold increase in d-lactic acid (0.7 mmol/mol creatinine, log-transformed). Healthy term infants in Greece were enrolled between birth and 72 hours of age, and block randomized to a probiotic (N = 44) or control (N = 44) group. They were exclusively fed their formulae until 28 days of age and followed up at 7, 14, 28, 112, and 168 ± 3 days. Anthropometric measurements were taken at each visit and tolerance recorded until 112 days. Urine was collected before study formula intake and at all visits up to 112 days and blood at 14 days. RESULTS: d-Lactic acid concentration in the probiotic group was below the non-inferiority margin at 28 days: treatment effect -0.03 (95% confidence interval [CI]: [-0.48 to 0.41]) mmol/mol creatinine but was above the non-inferiority margin at 7 and 14 days-treatment effect 0.50 (95% CI: [0.05-0.96]) mmol/mol creatinine and 0.45 (95% CI: [0.00-0.90]) mmol/mol creatinine, respectively. Blood acid excess and pH, anthropometry, tolerance, and adverse events (AEs) were not significantly different between groups. CONCLUSION: Intake of L. reuteri-containing formula was safe and did not cause an increase in d-lactic acid beyond two weeks.

Impact of postpartum influenza vaccination of mothers and household contacts in preventing febrile episodes, influenza-like illness, healthcare seeking, and administration of antibiotics in young infants during the 2012-2013 influenza season.

BACKGROUND: Influenza is associated with an increased risk for serious illness, hospitalization, and mortality in infants aged <6 months. However, influenza vaccines are not licensed for administration in this age group. The study evaluated the effectiveness of postpartum influenza vaccination of mothers and household members in infants. METHODS: The influenza vaccine was offered to mothers and household members of neonates born or hospitalized in 3 hospitals prior to the 2012-2013 season. Mothers were contacted every 2 weeks during the influenza season, and data regarding the onset of fever and/or respiratory symptoms in infants, healthcare seeking, hospitalization, and administration of antibiotics were collected. RESULTS: The study group consisted of 553 mothers who delivered 573 neonates. The influenza vaccine was administered to 841 of 1844 (45.6%) household contacts. Vaccination coverage rates ranged between 41.9% for neonates siblings and 49% for mothers. Five hundred thirty infants were analyzed for vaccine effectiveness. For outcomes in the infant, postpartum maternal vaccination had 37.7% effectiveness against acute respiratory illness (ARI), 50.3% against a febrile episode, 53.5% against influenza-like illness (ILI), 41.8% against related healthcare seeking, and 45.4% against administration of antibiotics. Multiple logistic regression analyses showed that maternal influenza vaccination was significantly associated with a decreased probability for febrile episodes, ARIs, and/or ILIs in infants, related healthcare seeking, and/or administration of antibiotics during the influenza season. Vaccination of other household contacts had no impact. CONCLUSIONS: Maternal postpartum vaccination against influenza was associated with a significant reduction of influenza-related morbidity, healthcare seeking, and antibiotic prescription in infants during the influenza season.

Serological and virological profile of chronic HBV infected women at reproductive age in Greece. A two-year single center study.

OBJECTIVE: Seroprevalence of HBsAg in 26,746 women at reproductive age in Greece and evaluation of HBeAg/anti-HBe serological status as well as serum HBV-DNA levels in a subgroup of HBsAg(+) women at labor. STUDY DESIGN: Serological markers were detected using enzyme immunoassays. Serum HBV-DNA was calculated using a sensitive quantitative PCR assay, with a lower limit of quantification of 200 copies/ml. RESULTS: Overall, 1.53% of women were HBsAg(+) and the majority of them (64.96%) were Albanian. Among Albanian women the mean prevalence of HBsAg was 4.9%, 5.57% among Asian women, and 1.29% among women from Eastern European countries. The prevalence of HBsAg among African (0.29%) and Greek women (0.57%) was very low and significantly lower in comparison with the mean value of the studied population. Only 2.67% of HBsAg(+) women were HBeAg(+). Of a subgroup of women in labor with available serum samples 28.6% had undetectable levels of viremia (<200 copies/ml) and 15.9% had extremely low levels of viral replication (<400 copies/ml). Only 12.7% of pregnant women evaluated at labor exhibited extremely high serum HBV-DNA levels (>10,000,000 copies/ml) whereas 42.8% of them exhibited HBV-DNA levels between 1500 and 40,000 copies/ml. CONCLUSIONS: The overall prevalence of HBsAg is relatively low among women at reproductive age in Greece but is higher among specific ethnic populations (Asian, Albanian). The HBeAg(-)/antiHBe(+) serological status is a finding observed in the vast majority of HBsAg(+) women of our study population, and a significant percentage of them (approximately 44.5%) exhibit extremely low or even undetectable levels of viral replication at labor, suggesting possibly that only a proportion of HBsAg(+) women in Greece exhibit an extremely high risk of vertical transmission of the infection.
