Perinatal HIV transmission risk has declined with increasing perinatal zidovudine use and changes in other factors. Further reduction in transmission for women taking zidovudine may be possible by reducing the incidence of other potentially modifiable risk factors, such as long duration of membrane rupture and prematurity.
High maternal viral load increases the likelihood of perinatal transmission of HIV-1 in women without AIDS and advanced immunosuppression. HIV-1 infected pregnant women without advanced disease, shown by others to have the lowest risk of perinatal transmission, may benefit the most from efforts to identify and decrease viral load at delivery.
Objective This study examined the prevalence of learning disability (LD), level of school achievement; and prevalence of grade retention by type of cleft and gender at two craniofacial centers. Setting The setting included two university-based craniofacial centers. Design/Patients Participants included 84 consecutively evaluated patients from one center who were matched by cleft type, age, and gender with 84 patients evaluated at the second center. Outcomes The outcomes included learning disability, school achievement, and grade retention. Results The results revealed that 46% of subjects with cleft had LD, 47% had deficient educational progress, and 27% had repeated a grade (excluding kindergarten) in school. Males with cleft palate only (CPO) had a significantly higher rate of LD than any other subject group. Males with CPO and females with cleft lip and palate (CLP) were more likely to repeat a grade in school than were females with CPO and males with CLP. Conclusions Children with cleft are at risk for learning disability, low school achievement, and grade retention.
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.
