Abstract
While rape and sexual violence have long been a widespread social problem, and one that has garnered significant attention, research that specifically examines the phenomenon of male victimization of sexual violence remains lacking. Addressing the gaps in the research, the current study uses 10 years of law enforcement data from the United States' National Incident-based Reporting System (2007-2016) on sexual victimization of males 14 years of age or older. The study sought to assess the impact of victim, offender, and incident characteristics associated with the outcome of the case (i.e., open, arrest, and exceptional clearance due to the victim declining or the prosecution refusing to pursue the case) for 20,701 male victims who reported a forcible sex offense to law enforcement as well as agency variation for cleared crimes. Using multilevel multinomial logistic regression, exceptionally cleared cases are more likely to resemble open cases than those resulting in arrest with incident characteristics having a larger influence than victim and offender characteristics. Cases involving concomitant offenses, committed by a stranger, resulting in injury, increase the likelihood of arrest-all of which support the "real rape" hypothesis. Exceptionally cleared cases represent more than one-third of cleared cases and there is significant department variation in the usage of exceptional clearance, as a number of agencies are exceptionally clearing more than half of their cleared cases, artificially increasing their clearance rate. These results, in conjunction with research on female victims, suggests that the handling of sexual assault cases reported to law enforcement remains problematic.

Abstract
BACKGROUND People who inject drugs (PWID) in Puerto Rico engage in high levels of injection and sexual risk behavior, and they are at high risk for HIV and hepatitis C (HCV) infection, relative to their US counterparts. Less is known, however, about the clustering of risk behavior conducive to HIV and HCV infection among rural Puerto Rican communities. OBJECTIVES The purpose of this study was to examine concurrent injection and sexual risk subtypes among a rural sample of PWID in Puerto Rico. METHODS Data were drawn from a respondent-driven sample collected in 2015 of 315 PWID in 4 rural communities approximately 30-40 miles from San Juan. Latent class analysis (LCA) was used to examine risk subtypes using 3 injection and 3 sexual risk indicators. In addition, demographic and other PWID characteristics were examined as possible predictors of latent class membership. RESULTS Four LCA subtypes were identified: low risk (36%), high injection/low sexual risk (22%), low injection/high sexual risk (20%), and high risk (22%). Younger age and past year homelessness predicted high risk latent class membership, relative to the other classes. In addition, daily speedball use predicted membership in the high injection/low sexual risk class, relative to the low risk and low injection/high sexual risk classes. CONCLUSION/IMPORTANCE The findings suggest ways in which PWID risk clusters can be identified for targeted interventions.

Abstract
INTRODUCTION In contrast to urban populations, little is known about polysubstance use among rural people who inject drugs (PWID), particularly in Puerto Rico where injection drug use and related health consequences are prevalent. The aim of the study is to compare injection and non-injection substance use profiles among separate urban and rural samples of Puerto Rican PWID. MATERIAL AND METHODS Data for the urban sample come from 455 PWID who participated in the CDC's National HIV Behavioral Surveillance survey of injection drug use in San Juan. The data for the rural sample come from 315 PWID residing in four rural cities approximately 40-miles from San Juan. Latent class analysis was used to derive separate urban and rural profiles of weekly injection and non-injection substance use. Injection behaviors were examined as possible correlates of latent class membership. RESULTS Five latent classes were identified in the urban sample, and three latent classes were identified in the rural sample. Classes were similar across samples; however, key differences emerged. Both samples had classes of primary heroin injectors, primary speedball injectors, and cocaine-heroin injectors. The urban sample had one high polysubstance class. Polysubstance use profiles that shared similar characteristics between samples also shared similar injection patterns, with some variation. DISCUSSION Variations in substance use patterns and associated health risks are likely shaped by social and geographic boundaries. CONCLUSIONS Understanding variations in substance use patterns across rural and urban locales may improve surveillance efforts and tailor desistance and harm reduction efforts at the state and local levels.

Abstract
Older women's risk of acquiring HIV should not be discounted, because researchers have noted that older women may be at an increased risk of contracting HIV due to their heterosexual sexual practices and/or substance use behaviors. HIV prevention efforts must be directed at older adults who engage in high-risk sexual and drug behaviors, particularly those who may not perceive themselves to be at risk for HIV infection. This study is based on 183 women, mostly African American, divided into two age cohorts (ages 18 to 29, and ages 40 and older). The authors investigate factors associated with HIV risk perception in several domains, including individual, psychosocial, and sociodemographic characteristics as well as sexual and drug use behaviors. Multivariate analyses revealed differences in factors associated with younger and older women's HIV risk perceptions. Our findings indicate a need for HIV risk prevention programs to take age into consideration when developing intervention messages and strategies.

Abstract
Latino adolescent reproductive health has become an increasingly important topic because of the growth in the numbers of Latino youth and because Latino youth are at high risk for negative reproductive health outcomes. Latinas now have the highest teen birth rates, and Latinos have disproportionately high rates of HIV/AIDS. These trends highlight the need for greater understanding of the sexual and reproductive health and behavior of Latino youth. This overview provides an introduction to key aspects of the Latino population. It then examines and synthesizes the existing literature by domains useful to the study of Latinos. Areas that receive in-depth coverage are socioeconomic status, family, national origin, peers and partners, and acculturation. Based on the current state of knowledge and the issues facing young Latinos, suggestions for future research and uses for existing data and past research are included.

Abstract
INTRODUCTION AND AIMS Little is known about injection-associated risk behaviours, knowledge and seroprevalence of viral infections among people who inject drugs (PWID) in nonurban locales in the US. Harm reduction services are more available in urban locales. The present study examined a cohort of active PWID residing in non urban areas of Connecticut to investigate how primarily injecting in urban or non urban areas was associated with injection-associated risk behaviours, knowledge and prevalence of blood-borne viruses. DESIGN AND METHODS We described the sample and performed bivariate and multivariable analyses on injection-associated risk behaviours, HIV/hepatitis/overdose knowledge and baseline serological data to identify differences between individuals who injected primarily in nonurban locales and those who did not. RESULTS Harm reduction knowledge and use of harm reduction services were poor in both groups. Those injecting most often in urban settings were 1.88 (1.19, 2.98 95% confidence interval) times more likely to engage in at least one injection-associated risk behaviour than their nonurban counterpart. Seroprevalence rates (23.6% for hepatitis B virus, 39.2% for hepatitis C virus, and 1.1% for HIV) were no different between the two groups. DISCUSSION AND CONCLUSIONS The data provided little evidence that the benefits of urban harm reduction programs, such as syringe exchange, risk reduction interventions and education programs have penetrated into this nonurban population, even among those who injected in urban locales where such programs exist. Harm reduction interventions for nonurban communities of PWID are needed to reduce HIV and hepatitis B and C transmission. [Grau LB, Zhan W, Heimer R.

Abstract
We assessed the efficacy of a Spanish-language HIV/AIDS and HIV testing video as a substitute for comparable orally-delivered information in healthcare and non-health care settings for Spanish-speakers regardless of health literacy level. In a non-inferiority clinical trial, Spanish-speaking Latinos from an emergency department, a clinic, and community-based organizations were randomly assigned to receive HIV/AIDS and HIV testing information orally or from a video. Comprehension of the information was measured using a questionnaire. Of the 150 participants, 39 % met criteria for lower health literacy and 75 % previously had been tested for HIV. Mean scores on the questionnaire for the video (20.4; 95 % CI 19.5 ~ 21.3) and the orally-delivered information arms (20.6; 95 % CI 19.7 ~ 21.5) were similar (Δ = -0.15; 95 % CI -1.4 ~ 1.1). Mean scores among lower health literacy participants also were similar (18.3 (video) vs. 19.6 (in-person); p < 0.30). This Spanish-language video is a viable substitute for orally-delivered HIV/AIDS and HIV testing information.

Abstract
BACKGROUND We have sought to identify ethnic- and gender-specific differences in HIV prevalence among heroin users receiving opioid maintenance treatment in the canton of Zurich, Switzerland. METHODS We used a generalized linear model (GEE) to analyze data from the anonymized case register for all opioid maintenance treatments in the canton of Zurich. Patients who received either methadone or buprenorphine between 1991 and 2012 (n=11,422) were evaluated for gender (male vs. female), ethnic background (Swiss vs. non-Swiss), and lifetime method of drug use (ever injector vs. non-injector). We addressed missing data by multiple imputation. RESULTS The overall prevalence of HIV among patients declined substantially from 33.7% in 1991 to 10.6% in 2012 in the complete dataset. In the imputed datasets, the respective prevalence dropped from 32.8% in 1991 to 9.7% in 2012. Non-injectors had a four to five times lower risk ratio (RR) compared to the reference group, 'Swiss males who ever injected'. In addition, we found a significantly higher risk ratio of HIV prevalence among females who had ever injected; this was true both for the complete dataset and the imputed dataset (Swiss RR 1.18 CI 95% 1.04-1.34, non-Swiss RR 1.58 CI 95% 1.18-2.12). CONCLUSION In this population, gender, ethnic background, and lifetime method of drug use influenced the risk of being HIV positive. Different access to treatment and different characteristics of risk exposure among certain subgroups might explain these findings. In particular, the higher risk for women who inject drugs-especially for those with an immigrant background-warrants additional research. Further exploration should identify what factors deter women from using available HIV-prevention measures and whether and how these measures can be better adapted to high-risk groups.

Abstract
Deported injection drug users (IDUs) in Mexico may be vulnerable to HIV infection following expulsion from the USA. We examined factors associated with HIV risk perception among a sample of deportees in Tijuana. From January to April 2010, 313 male IDUs who reported ever being deported from the USA completed a questionnaire. Overall, 35% (N=110) of deportees perceived HIV risk. In multivariate logistic regression analyses, factors independently associated with HIV risk perception included ever having a steady female partner in Tijuana post-deportation (adjusted odds ratio [AOR]: 2.26; 95% confidence interval [CI]: 1.01-5.07) and years spent in a US prison (AOR: 1.29 per year; 95% CI: 1.13-1.48). Conversely, years of drug injection use (AOR: 0.95 per year; 95% CI: 0.91-0.99), ever witnessing family members use drugs prior to first migration trip (AOR: 0.24; 95% CI: 0.09-0.65), years of residence in the USA (AOR: 0.91 per year; 95% CI: 0.84-0.98) and being a Tijuana native (AOR: 0.40; 95% CI: 0.16-0.99) were negatively associated with HIV risk perception. US-Mexico border cities that receive deported migrants should target HIV prevention interventions to specific subgroups, including drug-using male deportees. Interventions should consider migrant's time in the USA, the role of their social networks, and reducing missed opportunities for HIV testing/education.

Abstract
HIV-negative injection drug users (IDUs) who engage in both receptive syringe sharing and unprotected sex ("dual HIV risk") are at high risk of HIV infection. In a cross-sectional study conducted in New York City in 2009, active IDUs aged ≥18 years were recruited using respondent-driven sampling, interviewed, and tested for HIV. Participants who tested HIV-negative and did not self-report as positive were analyzed (N = 439). Adjusted odds ratios (aOR) and 95 % confidence intervals (95 % CI) were estimated using multinomial logistic regression. The sample was: 77.7 % male; 54.4 % Hispanic, 36.9 % white, and 8.7 % African-American/black. Dual risk was engaged in by 26.2 %, receptive syringe sharing only by 3.2 %, unprotected sex only by 49.4 %, and neither by 21.2 %. Variables independently associated with engaging in dual risk versus neither included Hispanic ethnicity (vs. white) (aOR = 2.0, 95 % CI = 1.0-4.0), married or cohabiting (aOR = 6.3, 95 % CI = 2.5-15.9), homelessness (aOR = 3.4, 95 % CI = 1.6-7.1), ≥2 sex partners (aOR = 8.7, 95 % CI = 4.4-17.3), ≥2 injecting partners (aOR = 2.9, 95 % CI = 1.5-5.8), and using only sterile syringe sources (protective) (aOR = 0.5, 95 % CI = 0.2-0.9). A majority of IDUs engaged in HIV risk behaviors, and a quarter in dual risk. Interventions among IDUs should simultaneously promote the consistent use of sterile syringes and of condoms.

Abstract
BACKGROUND In the United States, Hispanics are disproportionately affected by HIV infection. However, Hispanic subgroups of varied national origin differ culturally and HIV may impact them differently. METHODS We used information on Hispanics/Latinos diagnosed with HIV during 2006-2009 in 40 states and Puerto Rico, and aged ≥13 years, reported to the Centers for Disease Control and Prevention through June 2010, to examine the distribution of disease by selected characteristics, including place of birth and place of residence at diagnosis. We used Poisson regression to calculate the estimated annual percent change in the rate of HIV diagnoses and estimated prevalence ratios of a short HIV-to-AIDS interval (AIDS diagnosis within 12 months of HIV diagnosis). Analyses were adjusted for reporting delays and missing risk factor information. RESULTS During 2006-2009, HIV infection was diagnosed among 33,498 Hispanics/Latinos. From 2006 to 2009, the annual rate of diagnoses decreased among Hispanics/Latinos [estimated annual percent change = -4.3%; 95% confidence interval (CI) = -6.5 to -2.0) including men (-2.8%; 95% CI = -5.2 to -0.4) and women (-9.8%; 95% CI = -13.2 to -6.3). The rate of HIV diagnosis remained stable by place of birth but decreased among Puerto Ricans (-13.1%; 95% CI = -17.0 to -9.0). Among Hispanics/Latinos, a short HIV-to-AIDS interval was more common in nonurban areas than in urban areas. DISCUSSION Diagnosis of HIV infection among Hispanics/Latinos decreased and HIV-to-AIDS intervals varied by place of birth and area of residence. To continue to decrease the incidence of HIV infection among Hispanics, prevention programs need to address cultural and regional differences.

Abstract
Little information exists on the population prevalence or geographic distribution of injection drug users (IDUs) who are Hispanic in the USA. Here, we present yearly estimates of IDU population prevalence among Hispanic residents of the 96 most populated US metropolitan statistical areas (MSAs) for 1992-2002. First, yearly estimates of the proportion of IDUs who were Hispanic in each MSA were created by combining data on (1) IDUs receiving drug treatment services in Substance Abuse and Mental Health Services Administration (SAMHSA)'s Treatment Entry Data System, (2) IDUs being tested in the Centers for Disease Control and Prevention (CDC) HIV-Counseling and Testing System, and (3) incident AIDS diagnoses among IDUs, supplemented by (4) data on IDUs who were living with AIDS. Then, the resulting proportions were multiplied by published yearly estimates of the number of IDUs of all racial/ethnic groups in each MSA to produce Hispanic IDU population estimates. These were divided by Hispanic population data to produce population prevalence rates. Time trends were tested using mixed-effects regression models. Hispanic IDU prevalence declined significantly on average (1992 mean = 192, median = 133; 2002 mean = 144, median = 93; units are per 10,000 Hispanics aged 15-64). The highest prevalence rates across time tended to be in smaller northeastern MSAs. Comparing the last three study years to the first three, prevalence decreased in 82% of MSAs and increased in 18%. Comparisons with data on drug-related mortality and hepatitis C mortality supported the validity of the estimates. Generally, estimates of Hispanic IDU population prevalence were higher than published estimates for non-Hispanic White residents and lower than published estimates for non-Hispanic Black residents. Further analysis indicated that the proportion of IDUs that was Hispanic decreased in 52% and increased in 48% of MSAs between 2002 and 2007. The estimates resulting from this study can be used to investigate MSA-level social and economic factors that may have contributed to variations across MSAs and to help guide prevention program planning for Hispanic IDUs within MSAs. Future research should attempt to determine to what extent these trends are applicable to Hispanic national origin subgroups.

Abstract
BACKGROUND International borders are unique social and environmental contexts characterized by high levels of mobility. Among drug users, mobility increases risk for human immunodeficiency virus (HIV) in part through its effects on the social environment. However, the social dynamics of drug users living in border regions are understudied. METHODS 1056 injection drug users (IDUs) residing in Tijuana, Mexico were recruited using respondent-driven sampling (RDS) from 2006 to 2007, and underwent surveys and testing for HIV, syphilis, and tuberculosis (TB). Using logistic regression on baseline data, we identified correlates of having ever injected drugs with someone from the US. RESULTS Almost half (48%) reported ever injecting drugs with someone from the US. In RDS-adjusted logistic regression, factors independently associated with having ever injected with someone from the US included: having greater than middle school education (Adjusted Odds Ratio [AOR] 2.91; 95% confidence interval [C.I.] 1.52, 5.91), speaking English (AOR 3.24, 95% C.I. 1.96, 5.36), age (AOR 1.10 per year; 95% C.I. 1.07, 1.14), age at initiation of injection drug use (AOR 0.90 per year; 95% C.I. 0.86, 0.94), homelessness (AOR 2.61; 95% C.I. 1.27, 5.39), and having ever been incarcerated (AOR 11.82; 95% C.I., 5.22, 26.77). No associations with HIV, syphilis, TB, drug use, or injection risk behavior were detected. CONCLUSION Findings suggest that IDU networks in Mexico and the US may transcend international borders, with implications for cross-border transmission of infectious disease. Binational programs and policies need to consider the structure and geographic distribution of drug using networks.

Abstract
The importance of identifying differences in HIV risk between Hispanic subgroups is the focus of this article. Data are drawn from two New York?based HIV-related studies: among Puerto Rican drug users and among new immigrants from Central America, the Dominican Republic, and Mexico. Results indicated that intercultural individuals (i.e., those involved in both Puerto Rican and mainland cultures) were less risky in terms of injection- and sex-related risk behaviors and that geographic and other contextual factors, along with cultural norms, influence risk behaviors for immigrants. Both studies indicate the need to differentiate subgroup factors affecting HIV risk and prevention behaviors to develop appropriate and effective community-based interventions. The study's limitations are noted.

Abstract
At the start of the HIV epidemic, 50% of new infections were among injection drug users (IDUs) in New York City. While HIV has declined among IDUs since the mid-1990s, parenteral transmission continues to overburden Blacks/Hispanic IDUs. Individual risk behaviors do not explain the distribution of HIV/AIDS among IDUs. Social and/or structural factors are likely fueling racial disparities creating a high-risk socioenvironmental context. While increased access to structural interventions (i.e., syringe exchange and pharmacy syringe access) is needed, it may not be sufficient to eliminate HIV/AIDS disparities among IDUs. Research on incorporating structural factors into intervention strategies is needed.

Abstract
The objective of this study was to examine lay health advisor (LHA) programs designed to promote health among US Latinos and the extent to which educator-only versus educator-plus-bridge programs differed in designs and outcomes achieved. Two independent coders reviewed 128 published articles on LHAs yielding information at two levels: (i) study design and participant and LHA characteristics from 61 studies that broadly compared educator-only versus educator-plus-bridge programs and (ii) implementation features and outcomes from 17 randomized controlled trials or quasi-experimental studies with outcome data. LHA programs have been widely used with Latinos in certain US regions; our findings indicate that LHAs are effective intervention agents. We identified differences between educator-only and educator-plus-bridge LHA programs, although the small number of educator-plus-bridge programs with outcome data limited comparisons. Major gaps remain in research targeting Latino subgroups other than Mexican immigrants/Mexican Americans. Sufficient research has evaluated LHA programs among Latinos on their ability to achieve health behavior and/or health status changes. In the future, more of a focus on organizational and policy changes is warranted. Questions remain about diversity in LHAs' characteristics and roles, which influence not only outcomes but also program sustainability and dissemination.

Abstract
To determine whether migration impacted on drug use and HIV-related risk behaviors among injection drug users (IDU), we identified participants in a prospective cohort of IDU (Vancouver Injection Drug User Study) who had reported migrating out of Greater Vancouver between May 1996 and November 2005. We compared risk behaviors before and after a move for individuals who migrated (movers) and for a similar period for non-movers using linear growth curve analyses. In total, 1,122 individuals were included, including 430 (38.3%) women and 331 (29.5%) Aboriginal participants. Among these, 192 (17.1%) individuals reported migrating out of Greater Vancouver between 1996 and 2005 while 930 (82.9%) did not. Movers were significantly younger than non-movers: 32.0 (Interquartile Range [IQR]: 24.3-39.2) and 34.6 (IQR: 26.9-40.8) respectively. A significant decrease in those reporting unstable housing, frequent heroin and cocaine injection occurred only in movers. Our findings suggest that, in this setting, risk-taking among IDU declines following periods of migration out of Greater Vancouver.

Abstract
OBJECTIVES We sought to identify factors associated with harmful microinjecting practices in a longitudinal cohort of IDU. METHODS Using data from the Vancouver Injection Drug Users Study (VIDUS) between January 2004 and December 2005, generalized estimating equations (GEE) logistic regression was performed to examine sociodemographic and behavioral factors associated with four harmful microinjecting practices (frequent rushed injecting, frequent syringe borrowing, frequently injecting with a used water capsule, frequently injecting alone). RESULTS In total, 620 participants were included in the present analysis. Our study included 251 (40.5%) women and 203 (32.7%) self-identified Aboriginal participants. The median age was 31.9 (interquartile range: 23.4-39.3). GEE analyses found that each harmful microinjecting practice was associated with a unique profile of sociodemographic and behavioral factors. DISCUSSION We observed high rates of harmful microinjecting practices among IDU. The present study describes the epidemiology of harmful microinjecting practices and points to the need for strategies that target higher risk individuals including the use of peer-driven programs and drug-specific approaches in an effort to promote safer injecting practices.

Abstract
BACKGROUND Hispanic subgroups of varied national origin differ culturally; overall, Hispanics in the United States are disproportionately affected by HIV infection. METHODS We analyzed cases of HIV infection that were diagnosed among Hispanics in 33 states and US-dependent areas during 2003-2006 and reported to the Centers for Disease Control and Prevention through June 2007. We used Poisson regression to calculate the estimated annual percent change in the number and rate of HIV diagnoses and used logistic regression to analyze the association between birthplace and a short (<12 months) HIV-to-AIDS interval. RESULTS HIV infection was diagnosed among 30,415 Hispanics. Of 24,313 with reported birthplace, 61% were born outside the continental United States. The annual number of diagnoses increased among Mexican-born males [estimated annual percent change = 8.8%; 95% confidence interval (CI) = 3.5 to 14.5] and Central American-born males (18.6%; 95% CI = 9.4 to 28.6) and females (24.6%; 95% CI = 8.8 to 42.7) but decreased among US-born Hispanic females (-8.2%; 95% CI = -13.3 to -2.8). A short HIV-to-AIDS interval was more common among Mexican-born Hispanics than among US-born Hispanics. DISCUSSION Diagnosis trends and HIV-to-AIDS intervals varied by place of birth. To decrease the incidence of HIV infection among Hispanics, prevention programs need to address cultural differences.

Abstract
We identified factors associated with shooting gallery attendance among injection drug users (IDUs) in two Mexico-US border cities. IDUs in Tijuana (n=222) and Ciudad Juarez (n=205), Mexico, who were >or=18 years and injected illicit drugs in the last month were recruited using respondent-driven sampling (RDS). An interviewer-administered survey collected sociodemographic and behavioral data. Logistic regression was used to examine correlates of shooting gallery attendance in each of the two cities. Homelessness and being arrested for syringe possession--both structural level factors--were associated with shooting gallery use in both cities. In Ciudad Juarez, younger age and having overdosed were also associated with shooting gallery use. Our study highlights the need for structural interventions that mitigate homelessness among IDUs and facilitate changes in law enforcement practices associated with shooting gallery use. Harm reduction interventions based within shooting galleries should also be considered to prevent transmission of blood-borne pathogens among IDUs.

Abstract
OBJECTIVE We examined correlates of HIV infection among injection drug users (IDUs) in Tijuana, Mexico, a city bordering the United States, which is situated on major migration and drug trafficking routes. METHODS IDUs aged > or =18 years were recruited using respondent-driven sampling. Participants underwent antibody testing for HIV and syphilis and structured interviews. Weighted logistic regression identified correlates of HIV infection. RESULTS Of 1056 IDUs, the median age was 37 years, 86% were male, and 76% were migrants. HIV prevalence was higher in female participants than in male participants (8% vs. 3%; P = 0.01). Most IDUs testing HIV-positive were previously unaware of their serostatus (93%). IDUs reported injecting with a median of 2 people in the prior 6 months and had been arrested for having injection stigmata (ie, "track-marks") a median of 3 times. Factors independently associated with HIV infection were being female, syphilis titers consistent with active infection, larger numbers of recent injection partners, living in Tijuana for a shorter duration, and being arrested for having track-marks. CONCLUSIONS Individual, social, and environmental factors were independently associated with HIV infection among IDUs in Tijuana. These findings suggest the need to intervene not solely on individual risk behaviors but on social processes that drive these behaviors, including problematic policing practices.

Abstract
AIMS To determine the contribution of heroin, prescription opioids, cocaine and alcohol/drug combinations to the total overdose death rate and identify changes in drug overdose patterns among New Mexico subpopulations. DESIGN We analyzed medical examiner data for all unintentional drug overdose deaths in New Mexico during 1990-2005. Age-adjusted drug overdose death rates were calculated by sex and race/ethnicity; we modeled overall drug overdose death adjusting for age and region. FINDINGS The total unintentional drug overdose death rate in New Mexico increased from 5.6 per 100 000 in 1990 to 15.5 per 100 000 in 2005. Deaths caused by heroin, prescription opioids, cocaine and alcohol/drug combinations together ranged from 89% to 98% of the total. Heroin caused the most deaths during 1990-2005, with a notable rate increase in prescription opioid overdose death during 1998-2005 (58%). During 1990-2005, the 196% increase in single drug category overdose death was driven by prescription opioids alone and heroin alone; the 148% increase in multi-drug category overdose death was driven by heroin/alcohol and heroin/cocaine. Hispanic males had the highest overdose death rate, followed by white males, white females, Hispanic females and American Indians. The most common categories causing death were heroin alone and heroin/alcohol among Hispanic males, heroin/alcohol among American Indian males and prescription opioids alone among white males and all female subpopulations. CONCLUSIONS Interventions to prevent drug overdose death should be targeted according to use patterns among at-risk subpopulations. A comprehensive approach addressing both illicit and prescription drug users, and people who use these drugs concurrently, is needed to reduce overdose death.

Abstract
Migration is one of many social factors contributing to the spread of HIV and other blood-borne or sexually transmitted infections (STI). Bringing together large numbers of people from diverse settings, the process of migration moves infected individuals to diverse geographic locations. Injection drug users (IDU) are a relatively mobile group, often moving between cities, smaller communities, and across international borders for reasons of work, security, or access to narcotics. This mobility indicates the potential for IDU who engage in risky behavior outside their home areas to transmit HIV infection to other IDU, their sex partners, and others in the population. The objectives of this review are to examine: (1) the influence of drug trafficking and the spread of drug use on the diffusion of HIV, (2) the influence of migration on drug use and HIV-related risk behaviors among migrants, and (3) the mobility patterns of IDU and its role in the spread of HIV. We also discuss the potential policy implications of addressing prevention and care issues in mobile drug using populations.

Abstract
HIV/AIDS has disproportionately impacted Hispanics/Latinos in the United States. This literature review focuses on the disparities that exist in the impact of HIV/AIDS across Hispanic subgroups. Elimination of these disparities requires attention to underlying biological, behavioral and psychological, social and cultural, and economic and structural factors. Attention to factors within these domains has important implications for the reduction of other health-related disparities that exist across Hispanic/Latino subgroups in the United States.

Analyses focused on the relation between sex role attitudes, sex education, anxiety, and consistent condom use. RESULTS Nearly 60% of Puerto Rican and Mexican American women received no sex education from parents. Twenty-one percent of Puerto Rican and 38.3% of Mexican American women reported no sex education in schools. Women with some sex education in school, less than 13 years of education, or higher sex role attitude scores were more likely than other women to have partners who consistently used condoms.

Abstract
The rate of HIV infection in the migrant farm worker community is 10 times the national average. A survey was conducted of 106 female migrant farm workers in rural Northwest Ohio to assess HIV knowledge. The average participant's age was 28.7 years, 78 spoke Spanish, and 47 had an < or =8th- grade education. Fifty-six women received their information on HIV/AIDS from television. Eighty-seven women identified sexual contact as the major source of HIV transmission and 54 women identified the combination of sex, use of needles, and blood contact as the important routes. Sixty-nine women identified both homosexual and heterosexual intercourse as risk factors. Only 58 women identified perinatal infection as a route of HIV transmission and 59 women knew that treatment was available to prevent perinatal transmission. Although the majority of women had a good general knowledge of HIV transmission, further prevention education on perinatal transmission is needed among this population.

Abstract
OBJECTIVES We compared injection-related HIV risk behaviors of Puerto Rican current injection drug users (IDUs) living in New York City and in Puerto Rico who also had injected in the other location with those who had not. METHODS We recruited Puerto Rican IDUs in New York City (n = 561) and in Puerto Rico (n = 312). Of the former, 39% were "newcomers," having previously injected in Puerto Rico; of the latter, 14% were "returnees," having previously injected in New York. We compared risk behaviors within each sample between those with and without experience injecting in the other location. RESULTS Newcomers reported higher levels of risk behaviors than other New York IDUs. Newcomer status (adjusted odds ratio [OR] = 1.62) and homelessness (adjusted OR = 2.52) were significant predictors of "shooting gallery" use; newcomer status also predicted paraphernalia sharing (adjusted OR = 1.67). Returnee status was not related to these variables. CONCLUSIONS Intervention services are needed that target mobile populations who are coming from an environment of high-risk behavior to one of low-risk behavior.

Abstract
OBJECTIVES We examined differences in HIV seroprevalence and the likely timing of HIV infection by birth region. METHODS We analyzed unlinked HIV antibody data on 61 120 specimens from 7 public health centers in Los Angeles County from 1993 to 1999. RESULTS Most (87%) immigrant clients were Central American/Mexican-born. HIV prevalence was similar for US- and foreign-born clients (1.8% [95% confidence interval (CI) = 1.7%, 1.9%] and 1.6% [95% CI = 1.5%, 1.8%], respectively). Seroprevalence was high among sub-Saharan African females and low among Asian/Pacific Islander males and females. For HIV-positive immigrants, the average age at and time since immigration were 20.6 years and 12.3 years, respectively. CONCLUSIONS The relatively young age at arrival and long time since arrival for HIV-positive foreign-born clients suggest that most were infected after immigration.

Abstract
PURPOSE This article describes 12 HIV Outreach Demonstration Projects funded by the Center for Substance Abuse Treatment in 1995, and the clients these projects served. The article also summarizes the findings of multivariate statistical analyses aimed at identifying important project and client characteristics that influenced project success in achieving two key outcomes: persuading at-risk clients to obtain HIV tests, and facilitating entry by substance-abusing clients into structured substance abuse treatment (SAT). METHODS Hierarchical linear modeling (HLM) analysis was used to conduct the analyses. RESULTS The findings support the hypothesis that HIV Outreach, as an integrated approach to addressing the multiple problems clients have due to substance abuse and related problems, can be an effective model for reaching clients who have not been reached through traditional means. IMPLICATIONS By implementing a complement of comprehensive HIV Outreach interventions, many of the HIV Outreach projects were successful in addressing the various needs of their clients. However, as detailed in this article, some services and service delivery procedures, were more effective than others in achieving project objectives.

Abstract
Photodynamic antimicrobial agents based on the well-established phenothiazinium biological stain methylene blue offer a simple method for the inactivation or destruction of pathogens contained in donated blood and blood products. The technique is currently concentrated on viruses and the disinfective procedure can be carried out in blood bags using basic low-power light sources. Pathogens of the bacterial, yeast and protozoal classes are also susceptible to phenothiaziniums. The photoantimicrobial mode of action is usually via oxidative damage to cellular components, either due to redox reactions between the agent and a biomolecular target or by the action of reactive oxygen species generated in situ by photodynamic action. The targeting of various microbial species is discussed in relation to the physicochemical make-up of the photosensitizers, and future directions are suggested.
