Urban communities vary from suburban and rural communities in several ways, which are reflected in a modified risk for different causes of chronic renal disease. Many rural communities are more similar to urban communities in regard to socioeconomic adversities, access to health care, and other related challenges. It is important to recognize that high population density is commonly associated with a unique set of cultural practices including higher rates of perceived stress, recidivism and incarceration, and substance abuse. Each of these may predispose to higher rates of selected renal disorders such as hypertensive nephrosclerosis, human immunodeficiency virus (HIV) nephropathy, and substance abuse-associated renal disease. Having an understanding of urban culture and lifestyle can increase the awareness of potential contributing factors to chronic renal failure (CRF) in this population and assist in developing screening programs for high-risk individuals, considering specific diagnoses that may not be readily apparent and implementing effective early treatment.

We examined the prevalence and correlates of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) risk behaviors in a large sample of severely mentally ill (SMI) patients. Risk levels were correlated with demographic factors, diagnosis, symptom severity, trauma history, post-traumatic stress disorder (PTSD), substance use disorder (SUD), and sexual orientation. SMI clients from urban and rural settings (N = 275) were assessed regarding HIV/AIDS risk behaviors, and hypothesized risk factors. Patients exhibited substantial levels of risky behavior, particularly sexual risk. Correlates of increased risk included SUD, trauma, male homosexual orientation, younger age, and symptom severity. Structural equation modeling identified SUD and sexual orientation as the primary determinants of both drug and sexual risk behavior. We conclude that specific illness related variables appear to have less impact on risk behavior among people with SMI than previously hypothesized. Substance abuse prevention and treatment may be the most effective means of reducing HIV risk in this population.

Hepatitis C virus (HCV) is a common chronic bloodborne virus infection that affects an estimated 2.7 million persons in the United States. HCV infection causes an estimated 8,000-10,000 deaths each year from cirrhosis and hepatocellular carcinoma and is the leading reason for liver transplantation. Because injection drug use is a major risk factor for both human immunodeficiency virus (HIV) and HCV transmission, publicly funded HIV counseling and testing sites (HIV CTS) may have a role in HCV prevention. To evaluate the need for HCV services at these sites, the Connecticut Department of Public Health (CDPH) conducted an anonymous HCV seroprevalence study among clients of HIV CTS. This report summarizes the results of this analysis, which indicate that, among clients of these HIV CTS, the prevalence of antibody to HCV (anti-HCV) was 9.8%, compared with 1.3% for HIV, with significantly higher prevalence among clients of substance abuse treatment sites (40.2%), compared with other sites (6.9%). HCV counseling and testing should be integrated into all HIV CTS, especially those associated with substance abuse treatment.

We examined patients' attitudes toward HIV testing in the setting of acute substance abuse treatment and determined the prevalence of offering routine on-site testing for human immunodeficiency virus (HIV) in inpatient state-funded detoxification centers in New England. Voluntary questionnaires were administered to patients (N = 66 respondents) at the only two state-funded inpatient drug detoxification treatment centers in Rhode Island, and a telephone survey of all state-funded inpatient detoxification facilities across the New England area was conducted. In New England, 17/38 (44.7%) of all state-funded inpatient detoxification facilities didnot routinely offer on-site HIV testing to clients. Of participants, 97% responded positively to the question, "Do you think HIV testing should be available to patients in drug detoxification facilities such as this one?" There were 89% who reported that they would cope "about the same" or "better" with receiving a positive HIV test result while in detoxification treatment versus elsewhere. The greatest number of participants ranked the Orasure HIV test, an assay for HIV-1 transmucosal antibody, as the test they would most prefer while in drug treatment. However, 59% of patients responded that the type of test offered would not make a difference in whether they chose testing. Most patients indicated that they would want to see a physician within a few days of a positive diagnosis of HIV infection. Despite the controversy surrounding the provision of HIV testing to patients in inpatient acute substance abuse treatment, HIV testing is desired among these patients provided that HIV clinical care is readily available.

Access to care by low-income persons and residents of rural and poor inner-city areas is a persistent problem, yet physicians tend to be maldistributed relative to need. The objectives were to describe preferences of resident physicians to locate in underserved areas and to assess their preparedness to provide service to low-income populations. A national survey was made of residents completing their training in eight specialties at 162 US academic health center hospitals in 1998, with 2,626 residents responding. (Of 4,832 sampled, 813 had invalid addresses or were no longer in the residency program. Among the valid sample of 4,019, the response rate was 65%.) The percentage of residents ranking public hospitals, rural areas, and poor inner-city areas as desirable employment locations and the percentage feeling prepared to provide specified services associated with indigent populations were ascertained. Logistic regressions were used to calculate adjusted percentages, controlling for sex, race/ethnicity, international medical graduate (IMG) status, plans to subspecialize, ownership of hospital, specialty, and exposure to underserved patients during residency. Only one third of residents rated public hospitals as desirable settings, although there were large variations by specialty. Desirability was not associated with having trained in a public hospital or having greater exposure to underserved populations. Only about one quarter of respondents ranked rural (26%) or poor inner-city (25%) areas as desirable. Men (29%, P <.01) and noncitizen IMGs (43%, P <.01) were more likely than others to prefer rural settings. Residents who were more likely to rate poor inner-city settings as desirable included women (28%, P =.03), noncitizen IMGs (35%, P =.01), and especially underrepresented minorities (52%, P <.01). Whereas about 90% or more of residents felt prepared to treat common clinical conditions, only 67% of residents in four primary care specialties felt prepared to counsel patients about domestic violence or to care for human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) or substance abuse patients (all 67%). Women were more likely than men to feel prepared to counsel patients about domestic violence (70% vs. 63%, P =.002) and depression (83% vs. 75%, P <.01). Underrepresented minority residents were more likely than other residents to feel prepared to counsel patients about domestic violence (P <.01) and compliance with care (P =.04). Residents with greater exposure to underserved groups were more prepared to counsel patients about domestic violence (P =.01), substance abuse (P =.01), and to treat patients with HIV/AIDS (P =.01) or with substance abuse problems (P <.01). This study demonstrates the need to expose graduate trainees to underserved populations and suggests a continuing role of minorities, women, and noncitizen physicians in caring for low-income populations.

Trauma care in South Africa has a number of unique challenges. South Africa is a large country with an uneven distribution of services; a restrictive infrastructure; severe financial restraints on the entire health system; and an overwhelming incidence of patients with human immunodeficiency virus, acquired immunodeficiency disease syndrome, and tuberculosis. Substance abuse and violence are common cofactors in trauma. A profile of injuries encountered in South Africa is discussed.

Homeless and runaway youth face a variety of health risks, including those related to substance abuse and use of unsterile needles. During 1998-1999, we recruited 201 Minneapolis homeless youths aged 15-22 years; these youths were interviewed by experienced street outreach workers from settings where street youth were known to congregate. Respondents spent a median of 6 months in the previous year living on the streets or "couch hopping." There were 37% who reported having 15 or more alcoholic drinks per week, 41% smoked 1 pack or more of cigarettes per day, and 37% used marijuana 3 or more times a week; 15% reported lifetime injection drug use, including 6% who used injection drugs within the previous month. Twenty percent had received a tattoo, and 18% body piercing with a needle that had not been sterilized or had been used by someone else. There were 68% who had been tested for human immunodeficiency virus (HIV), 52% for hepatitis B, and 25% for hepatitis C. There were 44% who said they did not have enough information about hepatitis B and C. Less than half (43%) received hepatitis B vaccine; however, 51% of unvaccinated youths indicated that they would receive vaccination if offered. These Midwestern homeless youths face multiple health risks, including those related to substance use and exposure to unsterile needles. Despite unsafe behaviors, many of these youths were interested in methods to protect their health, including education, knowing their HIV or viral hepatitis serostatus, and obtaining hepatitis B immunization.

Injection drug users represent a major vector of human immunodeficiency virus (HIV) infection in the nation's inner cities, and are an important population for harm reduction treatment interventions to target. However, there has been relatively little research examining the specific contribution of the multiple factors contributing to cognitive functioning among injection drug users that may affect engagement in, and response to, addiction and HIV-related interventions. The current study examined the independent contributions to neuropsychological (NP) test performance of premorbid educational attainment, medical and psychiatric history, long- and short-term drug use, assessed by laboratory, observation, and self-report measures, and HIV disease, assessed by plasma HIV-1 RNA viral load and CD4+ count, in a sample of 90 HIV-positive injection drug users dually addicted to heroin and cocaine. Fully 88% of the sample showed evidence of impairment (>1 standard deviation below the population mean) on an NP test battery selected to assess processes associated with successful engagement in the treatment of substance abuse and HIV, such as learning and memory of verbal information, capacity to solve new problems and deal with more than one stimulus at a time, visual-motor coordination, and visual tracking and cognitive flexibility. In addition to drug use, independent predictors of NP test performance were HIV viral load, educational attainment, and premorbid medical and psychiatric problems. Findings underscore the multiplicity of factors that contribute to cognitive impairment in HIV-positive drug-abusing individuals in addition to drug use. Clinical implications are discussed.
