New Ballad Score, expanded to include extremely premature infants
ABSTRACT The Ballard Maturational Score was refined and expanded to achieve greater accuracy and to include extremely premature neonates. To test validity, accuracy, interrater reliability, and optimal postnatal age at examination, the resulting New Ballard Score (NBS) was assessed for 578 newly born infants and the results were analyzed. Gestational ages ranged from 20 to 44 weeks and postnatal ages at examination ranged from birth to 96 hours. In 530 infants, gestational age by last menstrual period was confirmed by agreement within 2 weeks with gestational age by prenatal ultrasonography (C-GLMP). For these infants, correlation between gestational age by NBS and C-GLMP was 0.97. Mean differences between gestational age by NBS and C-GLMP were 0.32 +/- 1.58 weeks and 0.15 +/- 1.46 weeks among the extremely premature infants (less than 26 weeks) and among the total population, respectively. Correlations between the individual criteria and C-GLMP ranged from 0.72 to 0.82. Interrater reliability of NBS, as determined by correlation between raters who rated the same subgroup of infants, ws 0.95. For infants less than 26 weeks of gestational age, the greatest validity (97% within 2 weeks of C-GLMP) was seen when the examination was performed before 12 hours of postnatal age. For infants at least 26 weeks of gestational age, percentages of agreement with C-GLMP remained constant, averaging 92% for all postnatal age categories up to 96 hours. The NBS is a valid and accurate gestational assessment tool for extremely premature infants and remains valid for the entire newborn infant population.

- "Each mother brought her infant to the follow-up clinic when the infant was 4 months old (age corrected for prematurity for infants below 37 weeks gestation; Ballard et al., 1991). Infants were videotaped in the BAIT (Garcia Coll et al., 1988, 1992). "
ABSTRACT: This was a prospective longitudinal multisite study of the effects of prenatal cocaine and/or opiate exposure on temperament in 4-month-olds of the Maternal Lifestyle Study ( N = 958: 366 cocaine exposed, 37 opiate exposed, 33 exposed to both drugs, 522 matched comparison). The study evaluated positivity and negativity during The Behavior Assessment of Infant Temperament (Garcia Coll et al., 1988). Parents rated temperament (Infant Behavior Questionnaire; Rothbart, 1981). Cocaine-exposed infants showed less positivity overall, mainly during activity and threshold items, more negativity during sociability items, and less negativity during irritability and threshold items. Latent profile analysis indicated individual temperament patterns were best described by three groups: low/moderate overall reactivity, high social negative reactivity, and high nonsocial negative reactivity . Infants with heavy cocaine exposure were more likely in high social negative reactivity profile, were less negative during threshold items, and required longer soothing intervention. Cocaine- and opiate-exposed infants scored lower on Infant Behavior Questionnaire smiling and laughter and duration of orienting scales. Opiate-exposed infants were rated as less respondent to soothing. By including a multitask measure of temperament we were able to show context-specific behavioral dysregulation in prenatally cocaine-exposed infants. The findings indicate flatter temperament may be specific to nonsocial contexts, whereas social interactions may be more distressing for cocaine-exposed infants.Development and Psychopathology 06/2015; -1:1-18.

- "GERD was based on need for antireflux medications as determined by the physician. Maturity level was measured as GA in weeks at birth, which was determined by physical examination using the New Ballard Score (Ballard et al., 1991). Milk type was assessed on the day when infants reached each milestone as either having some breast milk or having formula and used as a time-varying covariate in the analysis because of its potential to affect the feeding progression. "
ABSTRACT: Among infants born prematurely, competence at oral feeding is necessary for growth and hospital discharge. Extremely preterm (EP) infants (28 weeks of gestational age [GA]) are at risk for a variety of medical complications, which can limit the infant's capacity to develop oral feeding competence. This study examined feeding progression by assessing timing of acquisition of five early feeding milestones among EP infants and the impact of immaturity and medical complications. A chart review was conducted for 94 EP infants who participated in a larger longitudinal randomized study. Feeding progression was defined as infants' postmenstrual age (PMA) at five milestones: first enteral feeding, full enteral feeding, first oral feeding, half oral feeding, and full oral feeding. GA at birth and five medical complications (neurological risk, bronchopulmonary dysplasia, necrotizing enterocolitis, patent ductus arteriosus, and gastroesophageal reflux disease) were used as potential factors influencing the feeding progression. Linear mixed models were used to examine feeding progression across the milestones and contributions of GA at birth and five medical complications on the progression, after controlling for milk type as a covariate. EP infants gradually achieved feeding milestones; however, the attainment of the feeding milestones slowed significantly for infants with younger GA at birth and the presence of medical complications, including neurological risk, bronchopulmonary dysplasia, necrotizing enterocolitis, and patent ductus arteriosus but not gastroesophageal reflux disease. Milk type was a significant covariate for all analyses, suggesting that infants fed with breast milk achieved each of five milestones earlier than formula-fed infants. Improved understanding of the timing of essential feeding milestones among EP infants and the contribution of specific medical conditions to the acquisition of these milestones may allow for more targeted care to support feeding skill development.Nursing research 05/2015; 64(3):159-167.

- "In brief, we included newborn twins born at the hospital maternity ward. The twins were thoroughly examined, including a clinical evaluation for congenital abnormalities by a neonatal nurse and Ballard score for gestational maturity (Ballard et al. 1991). Twin mothers were interviewed regarding age, ethnic group and socio-economic characteristics. "
ABSTRACT: Objective To examine mortality and hospitalisations among infant twins and singletons after the perinatal period in Guinea-Bissau.Methods The study was conducted from September 2009 to November 2012 by the Bandim Health Project (BHP). Newborn twins and unmatched singleton controls were included at the National Hospital Simão Mendes in the capital Bissau. Children were examined clinically at enrolment. Maternal, pregnancy and obstetric information was collected and HIV testing offered at birth. Follow-up occurred at home at 2, 6 and 12 months and through linkage with the paediatric admission register at the National Hospital.ResultsAbout 495 twins and 333 singletons were alive on day 7 after birth. In total, 36 twins and 12 singletons died during follow-up, the post-perinatal infant mortality rate being 91/1000 person-years for twins and 42/1000 for singletons (HR = 2.11, 95% CI: 1.09–4.07). In a multivariable analysis among twins only, birth weight <2000 g [3.32, (1.36–8.07)], death of the cotwin perinatally [2.54, (1.16–5.57)] and severe maternal illness during pregnancy [2.35, (1.00–5.51)] were significant risk factors for twin death. In the subgroup with available HIV status, maternal HIV infection was strongly associated with twin mortality [3.16, (1.24–8.05)]. Death occurred at home for 60% of twins and 67% of singletons. During follow-up, 90 first-time hospital admissions were registered, with similar rates observed for twins (139/1000) and singletons (143/1000) [0.97, (0.61–1.52)].Conclusion The post-perinatal infant mortality rate of twins was double that of singletons. No excess in twin hospitalisations was observed, possibly implying obstacles to hospital admission for twins in case of severe illness.Tropical Medicine & International Health 09/2014; 19(12).
