We compared face-to-face and videoconference delivery of an education programme for health professionals on the subject of neonatal stabilization skills. A pre-test/post-test control group design was used to compare knowledge acquisition and satisfaction between the two modalities. There were no statistically significant differences between delivery modalities for knowledge acquisition. Both groups showed significant gains in knowledge when pre- and post-test scores were compared. Responses to most of the items in a survey of satisfaction with the course did not differ significantly between the two groups. Face-to-face participants expressed higher levels of comfort in interacting with the presenter, and those in the videoconference group were more willing to receive the course via videoconference in the future. Videoconferencing provided an effective and acceptable way of delivering neonatal stabilization skills. [ABSTRACT FROM AUTHOR]

Summary: We examined (1) the observer variability (both interobserver and intraobserver) in interpretation of abdominal radiographs of infants with suspected necrotizing enterocolitis (NEC), (2) the interobserver variability for individual radiologic signs used to diagnose NEC, and (3) the influence of experience in determining the extent of observer variability. Our hypotheses were (1) there would be considerable observer variability in interpretation of abdominal radiographs of infants with suspected NEC; (2) the extent of observer variability would differ for individual radiologic signs of NEC; and (3) the extent of observer variability would be determined by the observer's experience. The participants included 12 observers: two pediatric radiologists, four attending neonatologists, three neonatal fellows, and three pediatric residents. The participating observers under similar interpretation conditions, twice independently, interpreted the same 40 pairs of abdominal radiographs from infants with suspected NEC. The interval between the two interpretations was 3 to 6 months. Intraobserver and interobserver variability was assessed by applying the Kappa statistic to the radiologic signs of NEC for the two separate interpretations. The observers were blinded to patient's identity and the clinical course. Each observer recorded the absence, suspicion, or presence of (1) intestinal distention, (2) air fluid levels; (3) bowel wall thickening, (4) pneumatosis intestinalis, (5) portal venous gas, (6) pneumoperitoneum, and (7) NEC. We found low intraobserver and interobserver agreements. There was considerable variation in observer variability for individual radiologic signs. Trained observers performed better than in-training observers. We conclude that the radiologic signs in isolation should not be considered reliable. We recommend studies to formulate more objective criteria for many of the radiographic features of NEC. Standardization and periodic enforcement o... [ABSTRACT FROM AUTHOR]

Objective:The objective of this study was to examine the changes in level of respiratory support following transfusion in neonates who require intermediate or intensive care.Study Design:Data on respiratory support were collected retrospectively from the medical record before, during and after transfusion. Neonatal post transfusion lung injury (NPTLI) was defined as an increase in the highest mean airway pressure (MAP) of ⩾2 cm H2O or FiO2 >0.15 in the 6-h after transfusion that persisted from 6 to 18 h post transfusion.Result:A total of 373 (330 packed red blood cell) transfusions were given to 108 infants. NPTLI occurred following 31 (8.3%) transfusions in 23 patients. During the first 6 h after transfusion, FiO2 or MAP was increased in 47 transfusions (12.6%) and the changes persisted in 31 transfusions (7.8%). Infants who developed NPTLI were less mature (27.1±0.7 vs 31.0±0.5 weeks; P=0.005) and of lower birth weight (1001±110 vs1692±104 g; P=0.001). Infants who developed NPTLI were more likely to develop necrotizing enterocolitis (6/24 vs 4/85; P=0.002) and die within 24 h of transfusion (5/22 vs 3/85; P=0.003).Conclusion:In neonates receiving intensive or intermediate care, blood transfusion was associated with need for increased respiratory support in a significant number of cases. Development of NPTLI was associated with poorer outcomes. [ABSTRACT FROM AUTHOR]

Objective:To compare neonatal outcomes of preterm infants (born at <32 weeks' gestation) with focal/spontaneous intestinal perforation (SIP), necrotizing enterocolitis (NEC)-related perforation, NEC without perforation or no NEC/perforation.Study Design:Retrospective cohort study of 17 426 infants admitted to Canadian neonatal intensive care units during 2010 to 2013. The primary outcome was a composite of mortality or morbidity (bronchopulmonary dysplasia, severe retinopathy, periventricular leukomalacia or nosocomial infection). Association of intestinal perforation with neonatal outcome was evaluated using multivariate logistic regression.Result:SIP was present in 178 (1.0%) infants, NEC-related perforation in 246 (1.4%) and NEC without perforation in 538 (3.1%). Any intestinal perforation was associated with higher odds of the composite outcome (adjusted odds ratio (AOR): 8.21, 95% confidence interval (95% CI) 6.26 to 10.8); however, the odds were significantly lower for focal/SIP compared with NEC-related perforation (AOR: 0.29, 95% CI 0.17 to 0.51).Conclusion:Of the two types of intestinal perforation, NEC-related perforation was associated with the highest risk of an adverse neonatal outcome.

Objective:To compare risk-adjusted changes in outcomes of preterm infants <29 weeks gestation born in 1996 to 1997 with those born in 2006 to 2007.Study Design:Observational retrospective comparison of data from 15 units that participated in the Canadian Neonatal Network during 1996 to 1997 and 2006 to 2007 was performed. Rates of mortality and common neonatal morbidities were compared after adjustment for confounders.Result:Data on 1897 infants in 1996 to 1997 and 1866 infants in 2006 to 2007 were analyzed. A higher proportion of patients in the later cohort received antenatal steroids and had lower acuity of illness on admission. Unadjusted analyses revealed reduction in mortality (unadjusted odds ratio (UAOR): 0.83, 95% confidence interval (CI): 0.63, 0.98), severe retinopathy (UAOR: 0.68, 95% CI: 0.50 to 0.92), but increase in bronchopulmonary dysplasia (UAOR: 1.61, 95% CI: 1.39 to 1.86) and patent ductus arteriosus (UAOR: 1.22, 95% CI: 1.07 to 1.39). Adjusted analyses revealed increases in the later cohort for bronchopulmonary dysplasia (adjusted odds ratio (AOR): 1.88, 95% CI: 1.60 to 2.20) and severe neurological injury (AOR: 1.49, 95% CI: 1.22 to 1.80). However, the ascertainment methods for neurological findings and ductus arteriosus differed between the two time periods.Conclusion:Improvements in prenatal care has resulted in improvement in the quality of care, as reflected by reduced severity of illness and mortality. However, after adjustment of prenatal factors, no improvement in any of the outcomes was observed and on the contrary bronchopulmonary dysplasia increased. There is need for identification and application of postnatal strategies to improve outcomes of extreme preterm infants. [ABSTRACT FROM AUTHOR]
