Long-Term Linear Growth and Puberty in Pediatric Liver Transplant Recipients
The Journal of pediatrics, 2013Co-Authors: Saeed Mohammad, Wanrong Yin, Ravinder Anand, Adda Grimberg, Elizabeth B. Rand, Estella M. AlonsoAbstract:Objective To explore Linear Growth, puberty, and predictors of Linear Growth impairment among pubertal liver transplant recipients. Study design Review of data collected prospectively through the Studies of Pediatric Liver Transplantation registry. Thirty-one variables were tested as risk factors for Linear Growth impairment, and factors significant at P Results A total of 892 patients surviving their first liver transplant by >1 year, with ≥1 height recorded, who were between 8 and 18 years old between the years 2005 and 2009 were included. Median follow-up was 70.2 ± 38.6 months, mean age was 12.9 ± 3.3 years, and mean height z-score (zH) was −0.5 ± 1.4 SD. Twenty percent had Linear Growth impairment at last follow-up. Of 353 subjects with Tanner stage data, 39% of girls and 42% of boys ages 16-18 years were not yet Tanner 5. Growth impairment rates were higher among boys than girls (30% vs 7%, P P P ≤ .0001), re-transplantation (OR 4.37, P = .001), non-white race ( P = .0026), and primary diagnosis other than biliary atresia ( P = .0105). Conclusions Linear Growth impairment and delayed puberty are common in pubertal liver transplant recipients, with pre-transplant Growth impairment identified as a potentially modifiable risk factor. Catch-up Growth by the end of puberty may be incomplete.

Linear Growth Patterns in Prepubertal Children Following Liver Transplantation
American journal of transplantation : official journal of the American Society of Transplantation and the American Society of Transplant Surgeons, 2009Co-Authors: Estella M. Alonso, R. Shepherd, Karen Martz, Wanrong Yin, Ravinder AnandAbstract:Factors impacting Linear Growth following pediatric liver transplantation (LT) are not well understood. This longitudinal analysis examines predictors of Linear Growth impairment in prepubertal children included in Studies of Pediatric Liver Transplantation. In 1143 children with serial measurements, mean height scores increased from -1.55 at LT to -0.87 and -0.68 at 24 and 36 months post LT with minimal subsequent catch up Growth observed until 60 months. Subgroup analysis of height measurements at 24 months (n = 696), 33.8% were below 10th percentile at 24 months post LT. Multivariate analysis revealed Linear Growth impairment more likely in patients with metabolic disease (OR 4.4, CI: 1.83-10.59) and >18 months of steroids exposure (OR 3.02, CI: 1.39-6.55). Higher percentiles for weight (OR 0.80, CI: 0.65-0.99) and height (OR 0.62, CI: 0.51-0.77) at LT decreased risk. Less Linear catch up was observed in patients with metabolic disease, non-Biliary atresia cholestatic diseases and lower weight and higher height percentiles prior to LT. Prolonged steroid exposure and elevated calculated glomerular filtration rate and gamma-Glutamyltransferase following LT were associated with less catch up Growth. Linear Growth impairment and incomplete Linear catch up Growth are common following LT and may improve by avoiding advanced Growth failure before LT and steroid exposure minimization.

Examine the local Linear Growth rate of collisional Rayleigh‐Taylor instability during solar maximum
Journal of Geophysical Research, 2006Co-Authors: Chien-chih LeeAbstract:[1] This study is the first attempt to examine the effects of terms in the Growth rate formula on the magnitude of Growth rate during April 1999 to March 2000 (solar maximum). The estimation of Linear Growth rate is based on the local Linear Growth rate of collisional Rayleigh-Taylor instability (Ossakow et al., 1979). The monthly average values of Linear Growth rate (γ) and associated terms are calculated from the electron profile of Jicamarca digisonde and the atmospheric quantities of MSISE-90 model under geomagnetic quiet condition. The result shows that the Linear Growth rate is an essential factor for the development of equatorial spread F (ESF). Furthermore, during this period, the monthly variation in gradient density scale length is neither correlated nor anticorrelated to that in Growth rate. In contrast, the monthly variations in the collision frequency and recombination rate are anticorrelated with that in Growth rate during this period. Additionally, the altitude range of γ profile is another important factor for the ESF generation.
