“…To achieve a normal daily weight gain of 20 to 30 g/day in this age group [11], the patients in our cohort consumed at S1P discharge an average of 117 ± 14 kcal/kg/day of fortified breast milk or infant formula that had an average caloric density of 26.6 kcal/oz, with 28 % requiring supplemental gastrostomy tube feeding.…”

Normal Interstage Growth After the Norwood Operation Associated With Interstage Home Monitoring

After stage 1 palliation (S1P) with a Norwood operation, infants commonly experience growth failure during the initial interstage period. Growth failure during this high-risk period is associated with worse outcomes. This study evaluated the growth patterns of patients enrolled in the authors’ interstage home-monitoring program (HMP), which uses a multidisciplinary team approach to nutrition management. From 2000 to 2009, 148 infants were enrolled in the HMP after S1P. Families recorded daily weights during the interstage period and alerted the interstage monitoring team about protocol violations of nutritional goals. Interstage monitoring and inpatient data from the S1P hospitalization were reviewed to identify risk factors for poor growth. Growth outcomes were compared with published norms from the Centers for Disease Control. Interstage survival for patients in the HMP was 98 % (145/148). Growth velocity during the interstage period was 26 ± 8 g/day. The weight-for-age z-scores decreased from birth to discharge after S1P (−0.4 ± 0.9 to −1.3 ± 0.9; p < 0.001) but then increased during the interstage period to the time of S2P (−0.9 ± 1; p < 0.001). The factors associated with improved growth during the interstage period included male gender, greater birth weight, full oral feeding at S1P discharge, and a later birth era. After S1P, infants enrolled in an HMP experienced normal growth velocity during the interstage period. Daily observation of oxygen saturation, weight change, and enteral intake together with implementation of a multidisciplinary feeding protocol is associated with excellent interstage growth and survival.

Commercial software package "Growth Analyser Viewer Edition" ("GAVE") aims to document, monitor and analyze growth and development in children and adolescents. Although its clinical and scientific use is widespread, there are no published studies that describe the method and its validation. We were informed that GAVE calculates the weight velocity (kg/year) at age t from the weight difference between t and 448 days earlier or at birth, divided by the time difference. We recently discussed a case of false child abuse diagnosis (Pediatric Condition Falsification), resulting in the separation of the child from its parents, in which GAVE played a negative contributing role. To prevent such inappropriate diagnoses, we analyzed GAVE from a schematic representation of the measured clinical weight curve, with precisely defined weight velocities. In conclusion, the 448 days included for weight velocity predictions by GAVE caused the erroneous outcomes. Until the necessary changes to the software are implemented and validated, we advise against the use of GAVE in infants younger than 1.5 years, if multiple weight changes occur within 448 days, and following a long-lasting weight velocity change. Our analysis suggests to discard all medical software packages that lack public description and proof of validation.

“…The difference between true velocity values based on individuals and the pseudo‐velocities that Danner et al created from the cross‐sectional growth charts is illustrated in Table 1, which compares infant and toddler weight velocity values from the WHO Longitudinal Study 3 with values by Danner et al 1 The 3rd to the 5th percentile weight velocities from the WHO study barely overlap with the values from Danner et al at the youngest ages and not at all after 6 months. The WHO 50th percentile values are at the lower end of Danner's 50th percentile range at younger ages and barely overlap after 12 months.…”

“…The recent publication by Dr Danner and colleagues 1 on weight velocity in infants and children is based on a misunderstanding about the nature of growth charts and the construction and use of growth velocity data. It is imperative for readers to appreciate these simple principles regarding growth velocity before considering the use of these data for clinical purposes.…”
