ICF-Based simple scale for children with cerebral palsy: Application of Mokken scale analysis and Rasch modeling.

Children with cerebral palsy (CP) are faced with long-term dysfunction. The International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY) has been proposed but the complicated procedure limits the feasibility of clinical application and the exploration of health degrees. This study was aimed to establish a Mokken scale based on the ICF-CY for CP, and then to estimate psychometric properties through the derived Rasch model. 150 children with CP were assessed by the categories of "b" and "d" components in the core set. The binarized data was screened by the Mokken scale analysis and utilized for generating a reliable Rasch model. The validity of the final model was checked by the correlation between person ability, Gross Motor Function Classification System (GMFCS) and total scores. Using the Mokken scale to guide Rasch modeling, we can parameterize the properties of ICF-CY and realize the simple assessment of person abilities for children with CP.

Factors related to completeness of medical abortion with mifepristone and misoprostol.

BACKGROUND: Medical abortion that occurs in early pregnancy is generally safe and successful, but incomplete medical abortion can result in complications. This study aimed to examine factors related to completeness of medical abortion with mifepristone and misoprostol, and then to provide a new direction for research into establishing complete abortion with mifepristone and misoprostol. METHODS: Sixty-three patients with early pregnancy requesting medical abortion with mifepristone and misoprostol were selected. Immunohistochemistry was used to detect the expression and location of progesterone receptor, estrogen receptor, insulin-like growth factor-1, and vascular endothelial growth factor in chorionic villi among these women. Reverse transcriptase polymerase chain reaction was then used to determine the expression of insulin-like growth factor-1 and vascular endothelial growth factor mRNA. RESULTS: According to the outcome of medical abortion, the women were divided into either the incomplete medical abortion group (n=34) or the complete medical abortion group (n=29). Immunohistochemical analysis showed that progesterone receptor and estrogen receptor protein expression was not detected in chorionic villi in the two groups. However, compared with the complete abortion group, there was a marked decrease in the expression of insulin-like growth factor-1 and a significant increase in the expression of vascular endothelial growth factor (p<0.05) in the incomplete abortion group. There was no significant difference in mRNA expression between the incomplete and complete abortion groups. CONCLUSION: The expression of insulin-like growth factor 1 protein and vascular endothelial growth factor protein in chorionic villi may be related to the outcome of medical abortion with mifepristone and misoprostol.
