Fathers' experiences of supporting their partners during their preterm infant's stay in the neonatal intensive care unit: a multi-method study.

OBJECTIVE: To explore how the fathers experience their role as a support for their partner and the relationship with them during their preterm infant's stay in the NICU. STUDY DESIGN: Multi-method longitudinal study involving ethnographic observation, semi-structured interviews, self-report questionnaires, and clinical information. Twenty fathers of preterm infants hospitalized in a level-III-NICU were included. Data were analyzed using thematic continent analysis. RESULTS: Three main themes were identified: support for mother (subthemes: putting mother's and infant's needs first; hiding worries and negative emotions; counteracting the sense of guilt; fear that the mother would reject the child), mother's care for the infant (subthemes: observing mother engaged in caregiving; mother has "something extra"), and couple relationship (subthemes: collaboration; bond). CONCLUSION: Fathers supporting their partners during the stay in the NICU experience emotional distress and the need for being supported that often are hidden. This demands a great deal of emotional and physical energy.

Levels of Growth Factors and IgA in the Colostrum of Women from Burundi and Italy.

Colostrum is produced in the first days postpartum. It is a known source of immune mediators for a newborn within the first week of life. Although it is still unclear if colostrum composition varies between populations, recent data suggest differences. Hepatocyte growth factor (HGF); transforming growth factor-ß (TGF-ß) 1, 2, and 3; and immunoglobulin A (IgA) are key immunological components of colostrum that stimulate neonatal gastrointestinal and immune system development. We aimed to investigate the differences in the concentration between immune markers in the colostrum of mothers living in Burundi and Italy, and to identify the factors associated with differences. In this cross-sectional birth cohort study, a total of 99 colostrum samples from Burundian (n = 23) and Italian (n = 76) women were collected at 0 to 6 days postpartum. A clinical chemistry analyser was used for IgA quantification and electro-chemiluminescence, for HGF and TGFß1-3 assessment. A univariate analysis and multivariate linear regression model were used for statistical testing. The concentrations of TGF-ß2 (p = 0.01) and IgA (p < 0.01) were significantly higher in the colostrum from the women residing in Burundi than in Italy, both in a univariate analysis and upon the adjustment for confounding factors. A similar trend is seen for HGF, reaching statistical significance upon a multivariate analysis. We found a moderate to strong positive correlation between the TGF-ß isoforms and IgA concentration in both countries (p < 0.01), with stronger concentration in the colostrum from Burundi. The results of this study are in support of previous data, suggesting that concentration of the immune active molecules is higher in the human milk of women residing in developing countries. However, with a small sample size, caution must be applied, as the findings require further confirmation. Future work should also be focused on other factors (e.g., lipid and microbial composition), as well as the investigation into colostrum and between populations comparison, adjusting for potential confounders.

Fathers' experiences with their preterm babies admitted to neonatal intensive care unit: A multi-method study.

AIM: The aim of this study was to investigate fathers' emotional experiences of their infant's preterm birth and subsequent stay in neonatal intensive care unit. BACKGROUND: When a baby is born preterm, there is also the premature interruption of the process of preparation for fatherhood. As a result, the impact on fathers of the preterm birth can bring negative consequences for the development of father-infant relationship. DESIGN: A multi-method approach was used which included ethnographic observation, semi-structured interviews with fathers, a self-report questionnaire and clinical information between September 2015-March 2017. METHOD: Data were analysed using a mixed-method: a thematic analysis of data from the interviews and quantitative analyses to detect possible clusters of fathers' emotional experiences and associations between clusters and fathers' and/or infants' characteristics. RESULTS: Two clusters were identified. The "fathers-of-preterm-infants" touched their baby as soon as they were given the opportunity and without fear that they would harm their infant. They were struck by their baby's physical appearance. In contrast, the "preterm fathers" preferred not to touch their baby when first given the chance, for fear of breaking/damaging/infecting her/him. They were struck both by the baby's physical appearance and by the technology/equipment around her/him and were afraid that their infant would die. All the "fathers-of-preterm-infants", but only just over half of the "preterm fathers", were actively engaged in their infant's care. Clusters were associated with the infant's gestational age. CONCLUSION: Fathers of preterm infants should receive personalized support specifically addressed to them and based on the infant's gestational age.

Predictive algorithms for early detection of retinopathy of prematurity.

PURPOSE: To evaluate sensitivity, specificity and the safest cut-offs of three predictive algorithms (WINROP, ROPScore and CHOP ROP) for retinopathy of prematurity (ROP). METHODS: A retrospective study was conducted in three centres from 2012 to 2014; 445 preterms with gestational age (GA) ≤ 30 weeks and/or birthweight (BW) ≤ 1500 g, and additional unstable cases, were included. No-ROP, mild and type 1 ROP were categorized. The algorithms were analysed for infants with all parameters (GA, BW, weight gain, oxygen therapy, blood transfusion) needed for calculation (399 babies). RESULTS: Retinopathy of prematurity (ROP) was identified in both eyes in 116 patients (26.1%), and 44 (9.9%) had type 1 ROP. Gestational age and BW were significantly lower in ROP group compared with no-ROP subjects (GA: 26.7 ± 2.2 and 30.2 ± 1.9, respectively, p < 0.0001; BW: 839.8 ± 287.0 and 1288.1 ± 321.5 g, respectively, p = 0.0016). Customized alarms of ROPScore and CHOP ROP correctly identified all infants having any ROP or type 1 ROP. WINROP missed 19 cases of ROP, including three type 1 ROP. ROPScore and CHOP ROP provided the best performances with an area under the receiver operating characteristic curve for the detection of severe ROP of 0.93 (95% CI, 0.90-0.96, and 95% CI, 0.89-0.96, respectively), and WINROP obtained 0.83 (95% CI, 0.77-0.87). Median time from alarm to treatment was 11.1, 5.1 and 9.1 weeks, for WINROP, ROPScore and CHOP ROP, respectively. CONCLUSION: ROPScore and CHOP ROP showed 100% sensitivity to identify sight-threatening ROP. Predictive algorithms are a reliable tool for early identification of infants requiring referral to an ophthalmologist, for reorganizing resources and reducing stressful procedures to preterm babies.

Microbiota network and mathematic microbe mutualism in colostrum and mature milk collected in two different geographic areas: Italy versus Burundi.

Human milk is essential for the initial development of newborns, as it provides all nutrients and vitamins, such as vitamin D, and represents a great source of commensal bacteria. Here we explore the microbiota network of colostrum and mature milk of Italian and Burundian mothers using the auto contractive map (AutoCM), a new methodology based on artificial neural network (ANN) architecture. We were able to demonstrate the microbiota of human milk to be a dynamic, and complex, ecosystem with different bacterial networks among different populations containing diverse microbial hubs and central nodes, which change during the transition from colostrum to mature milk. Furthermore, a greater abundance of anaerobic intestinal bacteria in mature milk compared with colostrum samples has been observed. The association of complex mathematic systems such as ANN and AutoCM adopted to metagenomics analysis represents an innovative approach to investigate in detail specific bacterial interactions in biological samples.

A modified echocardiographic approach improves reliability of superior vena caval flow quantification.

OBJECTIVE: To assess accuracy and repeatability of a modified echocardiographic approach to quantify superior vena cava (SVC) flow volume that uses a short-axis view to directly measure SVC area and a suprasternal view to measure flow velocity, both at the level of the right pulmonary artery. SETTING: Three tertiary-level neonatal intensive care units. DESIGN: This was a multicentre, prospective, observational study. Accuracy of the traditional and modified approach was first assessed by comparing echo measurements according to both techniques with Phase contrast MRI (PCMRI) assessments, in a cohort of 10 neonates. In a second cohort of 40 neonates, intraobserver scan-rescan repeatability and interobserver analysis-reanalysis repeatability were assessed by repeated SVC flow echo measurements, according to both techniques. RESULTS: The traditional echocardiographic approach to assessment of SVC flow had a moderate agreement with PCMRI (r2 0.259), a scan-rescan intraobserver repeatability index (RI) of 37% (limits of agreement (LOA) -47/+51 mL/kg/min) and an interobserver analysis-reanalysis RI of 31% (LOA -38/+40 mL/kg/min). The modified approach showed a stronger agreement with PCMRI (r2 0.775), an improved intraobserver scan-rescan repeatability (RI 22%, LOA -24/+18 mL/kg/min) and improved interobserver analysis-reanalysis repeatability (RI 18%, LOA -18/+20 mL/kg/min). CONCLUSIONS: Echocardiographic assessment of SVC flow volume by tracing area from a short-axis view and measuring velocity-time integral from a suprasternal view offered an improvement in accuracy and repeatability, building on the traditional approach previously described.

Protein C concentrate as adjuvant treatment in neonates with sepsis-induced coagulopathy: a pilot study.

The objective of the study is to describe safety and effects of protein C concentrate (PCConc) administration in neonates with sepsis-induced coagulopathy. Eighteen neonates (12 preterm and 6 full term) aged between 1 and 28 days who have severe sepsis (n = 6) or septic shock (n = 12), with coagulopathy and acquired protein C (PC) deficiency received PCConc (i.v. bolus of 100 IU/kg, followed by 50 IU/kg every 6 h for 72 h). Platelet counts, prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen, D-dimer, C-reactive protein (CRP), antithrombin (AT), PC, CRP, and neonatal therapeutic intervention scoring system (NTISS) were assessed before and 24, 48, and 72 h after the study entry. According to Clinical Risk Index for Babies II score (CRIB II score), the expected mortality in preterms was 10%. After 24 h of treatment, PC activity levels increased from an average of 19% to 57%, and they were within normal limits before the last PCConc bolus. During the treatment period, a shortening of PT (P = 0.04) and activated partial thromboplastin time (P = 0.02), and an increase in antithrombin levels (P < 0.0001) were observed, along with a reduction in CRP (P = 0.005) and NTISS values (P = 0.003). No adverse events were observed. This pilot study shows that in neonatal severe sepsis, normalization of PC levels is safe and probably effective in modulating the inflammatory response and in controlling coagulopathy. However, for the potential beneficial effects of PCConc administration on morbidity and mortality, a placebo-controlled, double-blind study is required.

Routine coagulation tests in newborn and young infants.

BACKGROUND: The diagnostic approach to haemostatic defects in the newborn is challenging and requires appropriate interpretation of coagulation tests according to reference values dependent on the postnatal age. METHODS: This investigation was designed to study the postnatal development of the human coagulation system in newborn infants and to develop appropriate reference ranges for prothrombin time (PT), activated partial thromboplastin time (APTT) and fibrinogen (FBG) according at the day of birth and for the following postnatal period (days 1, 2, 3, 4, 5, 6, from 7 to 10 and from 11 to 44). RESULTS: The mean FBG value was already within the adult reference range in newborns at birth, the mean PT value fell within the adult reference range in infants aged 4 days or more, whereas the mean APTT value was still higher than the upper limit of the adult reference range in infants aged between 11 and 20 days. The prevalence of infants with pathological values according to the actual adult reference ranges was limited for FBG (from 24 to 7%), decreased from 92 to 8% in infants aged 0 and 11-20 days for PT, but remained elevated throughout the observational period for APTT (from 94 to 71%). CONCLUSIONS: The results of the present investigation demonstrate that the actual adult reference ranges for coagulation screening tests, especially PT and APTT, cannot be applied to newborns and young infants.

The influence of timing of elective cesarean section on risk of neonatal pneumothorax.

OBJECTIVE: To determine whether the timing of elective cesarean delivery at term influences the risk of neonatal pneumothorax. STUDY DESIGN: Chart reviews confirmed gestational age, delivery modalities, and diagnosis of pneumothorax of 66,961 term infants delivered in the Veneto region of northern Italy. Of these neonates, 17,783 (26.5%) were delivered by cesarean section, including 9988 elective (56.1%) and 7795 emergency (43.8%). RESULTS: In 5498 (55.0%) of neonates, an elective cesarean section was performed before 39 completed weeks. Fifty-nine neonates had pneumothorax diagnosed (0.88/1000 births). Neonates delivered by elective cesarean section had an increased incidence of pneumothorax (2.90/1000 births), in comparison with neonates delivered by emergency cesarean (1.53/1000 births; OR 4.21; 95% CI 2.02-8.74) or vaginally delivered (0.39/1000 births; OR 7.95; 95% CI 4.41-14.32). In elective cesarean sections there was a significant progressive reduction in the incidence of pneumothorax from week 37 0/7 to 37 6/7 onward (P < .01). CONCLUSIONS: The timing of elective cesarean section influences the pneumothorax risk. A reduction in neonatal iatrogenic pneumothorax would result if elective deliveries were performed after the 39 completed weeks of pregnancy.

Familial haemophagocytic lymphohistiocytosis: survival of a premature twin with immuno-chemotherapy and bone marrow transplantation from an HLA-identical unrelated donor.

UNLABELLED: We describe a premature twin born at 30 wk of gestational age, affected with familial haemophagocytic lymphohistiocytosis. Two different mutations were identified in his DNA: one inherited from the mother and one from the father. Haemophagocytosis had been confirmed in his twin brother, who died soon after birth, as well as in the re-evaluation of the autopsy of his older sister, who died 1 y earlier. At 26 d of age, chemotherapy and immune-suppressive treatment were started according to the HLH-94 protocol. At 6 mo of age, a bone marrow transplant from an HLA-identical, unrelated volunteer was performed. Now at 32 mo of age, the infant is healthy and without signs of graft-versus-host disease. CONCLUSION: This case report shows that immuno-chemotherapy and allogenic bone marrow transplant are feasible even in premature infants affected with familial haemophagocytic lymphohistiocytosis, which should be ruled out in unknown bleeding disorders of neonates.

Antepartum management and neonatal outcome of triplet pregnancies.

MATERIALS AND METHODS: The maternal and neonatal outcome of 27 triplet and 1 quadruplet gestations was studied at the University Hospital of Verona. RESULTS: Mean maternal age was 31.7+/-3.7 years; 24 women (85.7%) were nulliparous. Six (21.4%) patients had conceived spontaneously. Common maternal complications were: preterm labor (78.6%), anemia (57.1%), preeclampsia (25.0%). Thirteen patients (46.4%) had cervical cerclage, 21(75%) received tocolysis, 20 (71.4%) corticosteroid prophylaxis, 4 (14.3%) unfractionated heparin. All patients underwent Caesarean section with mean gestational age of 32+/-2.5 weeks and mean postoperative stay was 9 days. Three patients were treated in ICU after delivery, 1 was hysterectomized and 6 received blood transfusions. The live newborns were 80, the stillborns 5. Mean birth weight was 1,520+/-516 g (range 650-2,665), 95.0% being LBW. The following neonatal complications were observed: RDS (28.7%), cerebral hemorrhage (26.2% of II degrees and 1.2% of III degrees ), anemia (20%), PDA (12.5%), ROP (6.5%), polyglobulia (3.75%), NEC (2.5%). Mean hospitalization time was 30.6 days (range 2-132). DISCUSSION: Iatrogenic multiple births are increasing as the use of assisted conception techniques expands. Gynecologists should be aware of maternal complications and neonatal outcome of triplet pregnancies and infertility management strategies should try to avoid iatrogenic multiple gestations.

Serendipitous diagnosis of infracardiac total anomalous pulmonary venous return by umbilical venous catheter blood gas samples.

Total anomalous pulmonary venous return (TAPVR) is a rare congenital heart defect that occurs when all four pulmonary veins connect to the systemic venous circulation. We describe a full-term male neonate who presented with cyanosis and mild tachypnea shortly after birth. One umbilical artery and the umbilical vein were catheterized, and oxygen treatment was provided. Four echocardiograms indicated severe pulmonary hypertension and were negative for any congenital heart defects. After the umbilical artery catheter was removed, high partial pressure of oxygen was detected in blood samples drawn from the umbilical venous catheter that was positioned below the diaphragm. Based on this finding, TAPVR was suspected and confirmed with angiography through a central venous catheter. The neonate underwent a successful surgical repair to correct the cardiac defect.
