STUDY OBJECTIVE We assess the feasibility, effectiveness, and cost of routinely recommended HIV/sexually transmitted disease screening in an urban emergency department (ED). METHODS From April 2003 to August 2004, patients aged 15 to 54 years were offered rapid HIV testing, and those aged 15 to 25 years were also offered gonorrhea and chlamydia testing(More)
Non-Latina black breast cancer patients experience a shorter survival from breast cancer than their non-Latina white counterparts. We compared breast cancer-specific survival for the subset of black and white patients with estrogen and/or progesterone receptor-positive tumors that are generally targeted with endocrine therapy. Using data collected from a(More)
The HschiA1 gene of the archaeon Halobacterium salinarum CECT 395 was cloned and overexpressed as an active protein of 66.5 kDa in Escherichia coli. The protein called HsChiA1p has a modular structure consisting of a glycosyl hydrolase family 18 catalytic region, as well as a N-terminal family 5 carbohydrate-binding module and a polycystic kidney domain.(More)
INTRODUCTION Non-Hispanic (nH) Black and Hispanic women are disproportionately affected by early onset disease, later stage, and with more aggressive, higher grade and ER/PR negative breast cancers. The purpose of this analysis was to examine whether genetic ancestry could account for these variation in breast cancer characteristics, once data were(More)
Small-area analysis in health is essential in uncovering local-level disparities often masked by health estimates for large areas (e.g., cities, counties, states). In this context, 14 health status indicators (HSIs) were examined for six Chicago community areas that reflect the substantial diversity of the city. HSIs were compared over time (from 1989–90 to(More)
OBJECTIVES Although local-level chronic disease and risk factor data are not typically available, they are valuable for guiding public health interventions and policies. To present a case for disaggregated community-level health data, we conducted a study exploring the relevance of such data to research on health disparities. METHODS We designed a(More)
BACKGROUND Racial/ethnic disparities exist along the breast cancer continuum, including time to a diagnosis. Previous research has largely focused on patient-level factors, and less is known about the role that health care facilities may play in delayed breast cancer care. OBJECTIVES We examined racial/ethnic disparities in delayed diagnosis for breast(More)
INTRODUCTION The quality of population-based cancer registries are largely defined by the completeness, accuracy, and timeliness of incident cases and demographics reported. However, both Surveillance, Epidemiology, and End Results (SEER) cancer registries and non-SEER population-based state cancer registries have been regularly used to examine treatment(More)
Conflicting study results with regards to racial/ethnic disparities in chemotherapy use among breast cancer patients may be due to the different sample populations, treatment data sources, and treatment eligibility definitions used. This study examined chemotherapy disparity in the context of changing treatment guidelines and explored factors that may help(More)
OBJECTIVES This study examined Chicago residents' progress toward the Healthy People 2000 goal of reducing racial disparities in health and compared the results with a recent analysis of US data. METHODS Non-Hispanic Black-to-non-Hispanic White rate ratios were computed for 14 health status indicators for 1990 and for 1998. RESULTS Nationally and in(More)
