Barriers to cancer clinical trial accrual can be prospectively identified and addressed in the development and conduct of future studies, which may potentially lead to more robust clinical trials enrollment. Investigation of patient perceptions regarding the clinical trials process and the role of third party-payers is warranted.

Based on data from 1979–1990 NLSY interviews, we investigate the implications of rising economic inequality for young men’s marriage timing. Our approach is to relate marriage formation to the ease or difficulty of the career-entry process and to show that large race/schooling differences in career development lead to substantial variations in marriage timing. We develop measures of current career “maturity” and of long-term labor-market position. Employing discrete-time event-history methods, we show that these variables have a substantial impact on marriage formation for both blacks and whites. Applying our regression results to models based on observed race/schooling patterns of career development, we then estimate cumulative proportions ever married in a difficult versus an easy career-entry process. We find major differences in the pace of marriage formation, depending on the difficulty of the career transition. We also find considerable differences in these marriage timing patterns across race/schooling groups corresponding to the large observed differences in the speed and difficulty of career transitions between and within these groups

Previous studies of racial inequality have relied on official statistics that presumably use self-classification of race. Using novel data from a 1995 national survey in Brazil, we find that the estimates of racial income inequality based on self-classification are lower than those based on interviewer classification. After human capital and labor market controls, whites earn 26% more than browns with interviewer classification but earn only 17% more than browns with self-classification. Black-brown differences hardly change: Blacks earn 13% and 12% less than browns with interviewer classification and self-classification, respectively. We contend that interviewer classification of race is more appropriate because analysts of racial inequality are interested in the effects of racial discrimination, which depends on how others classify one's race.

In patients with chronic hepatitis C, 23.0% had elevated serum AFP that is independently associated with stage III/IV hepatic fibrosis, elevated level of AST, and prolonged INR.

Objective To determine whether eligible extremely-low-birth-weight children (<1000 g) were enrolled in the federally enacted, state-coordinated Early Intervention (EI) program intended to help children with developmental delay or disability regardless of parental income, and the factors associated with enrollment. Methods Retrospective analysis of 884 EI-eligible ELBW children born in South Carolina with birth weight 401 to 999 g, gestation ≥24 weeks, and survival for the first 120 days of life. We created a linked data set with data from Early Intervention (1996–2001), Vital Records (1996–1998), death certificates, and Medicaid. Each child was followed from birth to 3 years old, the program eligibility period. Results A total of 54% of ELBW children were enrolled in EI at any time from birth to 36 months. Even among children ever enrolled in Medicaid (83% of all ELBW children), only 63% were enrolled in EI. Being born in a multiple gestational birth, having heavier birth weight (750 to 999 g), and having ever enrolled in Medicaid were positively associated with EI enrollment. Among Medicaid patients for whom perinatal data were available, additional risk adjustment showed that EI enrollment was more likely with birth in level 3 hospitals, birth weight 750 to 999 g, Neonatal Medical Index severity level V (most severe), and longer initial length of hospital stay. Conclusions Only about half of eligible ELBW children in South Carolina were enrolled—much lower than reported elsewhere. Efforts are needed to understand why eligible infants are not being enrolled and to develop strategies to remedy the situation.

The authors adapt the segmented assimilation theory to a model of population health, which posits that assimilation is actually harmful to migrants' health. The authors also specify models of individual and contextual factors to indirectly test the theory of segmented assimilationa theory that posits interactions between individual and residential circumstances.
