BACKGROUND Patients with human immunodeficiency virus (HIV) infection need lifelong medical care, but many do not remain in care. The effect of poor retention in care on survival is not known, and we sought to quantify that relationship. METHODS We conducted a retrospective cohort study involving persons newly identified as having HIV infection during(More)
BACKGROUND Diabetes has been associated with an increased risk of hepatocellular carcinoma (HCC) in studies of referred patients. This is the first population based case control study in the USA to examine this association while adjusting for other major risk factors related to HCC. METHODS We used the Surveillance Epidemiology and End-Results Program(More)
BACKGROUND Poor retention in HIV care leads to poor survival. The predictors of poor retention in HIV care are not well understood, especially from US nationwide datasets. We determined the predictors of poor retention in HIV care among a group of US veterans and examined whether poor retention was confounded by other predictors of survival. METHODS We(More)
UNLABELLED Surveillance for hepatocellular carcinoma (HCC) in patients with cirrhosis is recommended but may not be performed. The extent and determinants of HCC surveillance are unknown. We conducted a population-based United States cohort study of patients over 65 years of age to examine use and determinants of prediagnosis surveillance in patients with(More)
BACKGROUND & AIMS The incidence of intrahepatic cholangiocarcinoma has been recently increasing in the United States. In this case-control study, we used the Surveillance, Epidemiology, and End Results-Medicare database to evaluate the prevalence of known risk factors for intrahepatic cholangiocarcinoma and explore other potential risk factors. METHODS We(More)
BACKGROUND Among elderly persons, falls account for 87% of all fractures and are contributing factors in many nursing home admissions. This study evaluated the effect of an easily implemented, low-intensity exercise program on the incidence of falls and the time to first fall among a clinically defined population of elderly men and women. METHODS This(More)
BACKGROUND AND AIMS A significant increase in the incidence of hepatocellular carcinoma (HCC) has been reported in the United States. The risk factors underlying this increase remain unclear. METHODS By using Surveillance, Epidemiology, and End-Results program (SEER)-Medicare-linked data, we conducted a population-based study to examine temporal changes(More)
A dozen studies have been published showing that opiate antagonists suppress alcohol drinking in animals, and two independent placebo-controlled, double-blind clinical trials of naltrexone found this agent was associated with decreased alcohol craving and consumption in alcohol-dependent patients. Nalmefene is a newer opiate antagonist that has a number of(More)
While large differences by race/ethnicity in breast cancer survival are well established, it is unknown whether differences in quality of chemotherapy delivered explain the racial/ethnic disparities in survival among black, Hispanic, Asian, and white women with breast cancer. We evaluated factors associated with time to initiation of adjuvant chemotherapy(More)
OBJECTIVE To assess the effectiveness of a Spanish surname match for improving the identification of Hispanic women in Medicare administrative data in which Hispanics are historically underrepresented. DATA SOURCES We collected self-identified race/ethnicity data (N=2,997) from a mailed survey sent to elderly Medicare beneficiaries who resided in 11(More)
