We recommend using the PH model for predicting mean LOS when the PH assumption for patients with different clinical characteristics is satisfied. However, the proposed method only applies to rehabilitating stroke patients.
We conclude that there was no significant difference of paediatric ESRD patient survival between HD and PD treatment in Taiwan. The older paediatric ESRD patients had better survival than younger patients.
Recent studies reveal that salivary cortisol measurements accurately refl ect blood cortisol levels in older children and adults; yet, the relationship between the two values in premature infants has not been established. This study explores the use of salivary cortisol as an accurate measure of adrenal steroid concentrations in premature infants to provide a reliable and less invasive tool for investigating hormonal stress response. Premature infants (n = 51) were recruited, with saliva and blood collected immediately after birth, and cortisol levels measured by radioimmunoassay. A linear relationship emerged between cord plasma and salivary cortisol values in the 102 paired samples [(salivary cortisol) = 0.546 + 0.192 × (plasma cortisol), r = 0.481 and p = 0.0003]. Findings demonstrated that salivary and plasma cortisol levels were correlated in premature infants. This information will be useful in future studies that assess use of salivary cortisol to evaluate neonatal stress axis function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
