RESUMEN
People who inject drugs (PWID) who migrate from Puerto Rico (PR) to New York City (NYC) are at elevated risk for hepatitis C (HCV), HIV and drug overdose. There is an urgent need to identify a sustainable path toward improving the health outcomes of this population. Peer-driven HIV/HCV prevention interventions for PWID are effective in reducing risk behaviors. Additionally, the concept of intravention-naturally occurring disease prevention activities among PWID (Friedman, 2004)-is a suitable theoretical framework to cast and bolster PWID-indigenous risk reduction norms and practices to achieve positive health outcomes. From 2017-2019, we conducted an ethnographic study in the Bronx, NYC to identify the injection risks of migrant Puerto Rican PWID, institutional barriers to risk reduction and solutions to these barriers. Study components included a longitudinal ethnography with 40 migrant PWID (e.g., baseline and exit interviews and monthly face-to-face follow-ups for 12 months), two institutional ethnographies (IEs) with 10 migrants and six service providers, and three focus groups (FGs) with another 15 migrant PWID. Data were analyzed using a grounded theory approach. In this article, we present findings from the IEs and FGs, specifically regarding a promising intravention pathway to promote health empowerment among these migrants that leverages an existing social role within their networks: the PR-indigenous ganchero. A ganchero is a vein-finding expert who is paid with drugs or cash for providing injection services. Ethnographic evidence from this study suggests that gancheros can occupy harm reduction leadership roles among migrant Puerto Rican PWID, adapting standard overdose and HIV/HCV prevention education to the specific experiences of their community. We conclude by noting the culturally appropriate risk reduction service delivery improvements needed to mitigate the health vulnerabilities of migrants and provide a roadmap for improving service delivery and identifying future research avenues.
RESUMEN
BACKGROUND: Among people who inject drugs (PWID) in New York City (NYC), racial minorities are disproportionately infected with HIV and hepatitis C (HCV). Prior research has shown that PWID who started injecting drugs in Puerto Rico (P.R.) tend to maintain the risky injection behaviors learned there. This study identifies the P.R.-native norms supporting the continued injection risk behavior of migrant Puerto Rican PWID in NYC to inform a culturally appropriate risk-reduction intervention. METHODS: 40 migrant Puerto Rican PWID were recruited in NYC for a longitudinal qualitative study. The sample was stratified to include 20 migrants with <3 years in NYC and 20 migrants with >3-6 years in NYC. Time-location sampling was used to curb possible network bias in recruitment. Over 12 months, migrants completed semi-structured interviews at baseline, monthly follow-ups, and study exit. Analyses were guided by grounded theory. RESULTS: Most participants (90%) reported having had chronic HCV, and 22.5% reported being HIV-positive. Syringe- and cooker-/cotton-sharing were widespread in both P.R. and NYC. The ubiquitous practice of cleaning used syringes by "water-rinsing and air-blowing" was guided by a normative belief, learned in P.R., that "water and air kill HIV." Sterile syringe use was not a priority. HCV was not a concern. P.R.-native abstinence-only narratives discouraged opioid agonist treatment (OAT) enrollment among recent migrants (≤3 years). Experiences with drug dealers, prison-power groups, and injection doctors ("Gancheros") in P.R. influenced migrants' injection risk behavior in NYC. Those who were Gancheros in P.R. continued working as Gancheros in NYC. CONCLUSIONS: Injection risks make migrant Puerto Rican PWID in NYC vulnerable to HIV/HCV. Harm reduction programs should pay closer attention to the rationales behind these injection risks. A risk-reduction intervention that incorporates the Ganchero figure may be a credible way to help migrants reduce injection risk and accept OAT and syringe exchange programs (SEP).

OBJECTIVE: The objective of this study was to assess the frequency of urinary tract infection (UTI) with urine samples obtained via catheterization among women undergoing cesarean delivery at term pregnancy. MATERIALS AND METHODS: A cross-sectional study involving 159 women in whom cesarean delivery was conducted at term pregnancy after a regular follow-up from first to third trimester. For screening and diagnosis of UTI during antenatal period, the authors used dipstick test and microscopic urinalysis, and urine culture was used in the presence of symptomatic UTI unresponsive to initial antibiotic therapy. A urine sample was obtained immediately after insertion of Foley catheter for urine dipstick test, microscopic urinalysis, and culture during cesarean delivery. Obstetric and UTI data were recorded. RESULTS: Of 159 pregnant women, 95 (59.8%) did not develop UTI during antenatal care. There was no patient with symptomatic UTI at the admission for cesarean delivery. The authors found UTI with urine dipstick and microscopic urinalysis in 12 patients and of them, four patients had no history of UTI, and all the remaining eight patients had asymptomatic UTI during antenatal follow-up. UTI according to urine culture was encountered in three patients, two of them had one episode of UTI, and one had two episodes of UTI during antenatal follow-up. CONCLUSIONS: After regular antenatal follow-up screening with urine dipstick, microscopic urinalysis, and counseling of pregnant women regarding UTIs, the frequency of bacteriuria decreases considerably during cesarean delivery.

OBJECTIVE: To study the influence of the sedatives propofol and midazolam on cardiovascular parameters in patients undergoing fiberoptic bronchoscopy (FOB). METHODS: 100 patients without a history of cardiac disease undergoing diagnostic FOB were investigated in a prospective-randomized design. After premedication with intramuscular atropine (0.01 mg/kg BW) patients received sedation with either propofol (group P, n = 50) or midazolam (group M, n = 50). Heart rate, arterial oxygen saturation (psaO (2)) and non-invasive blood pressure were recorded prior to and immediately after induction of sedation, when at the level of vocal cords, during the interventional diagnostic procedure (IDP) and 15 min after the end of the FOB. RESULTS: The mean heart rate and systolic pressure were significantly lower in group P when compared with group M when at the level of vocal cords and during the IDP (p < 0.05). The total incidence of major arrhythmias was 10 % and the incidence of minor arrhythmias was 62 %. A decline in psaO (2) < 90 % occurred in 16 patients of group M and 5 patients of group P (p = 0.44). CONCLUSION: Propofol, when used as a sedative for FOB, is associated with lower hemodynamic side effects than in patients undergoing FOB with midazolam. In addition, it is well-tolerated by patients with pre-existing pulmonary disease. Even patients without a history of heart disease should be monitored for cardiac arrhythmia while undergoing FOB for pulmonary disease, especially patients with a FEV (1) of less than 50 % of the predicted value.

A dual site project was conducted to assess determinants of injection and sex-related risk behaviors among Puerto Rican drug users. The project focused on injection drug users and crack smokers, and was conducted in East Harlem, NY and Bayamón, PR in 1996-2000. Qualitative methods included ethnographic mapping, focus groups, in-depth interviews, and observations. A survey component (East Harlem, n = 800; Bayamón, n = 400) was also conducted. Procedures to ensure integration of methodologies and comparability of data were developed. This paper describes the qualitative and survey methods used, and presents the comparative HIV risk behaviors. The integration of the two methodologies served multiple functions: each component identified issues to be addressed in the other, enhanced cross-site comparability of data, and assisted in interpretation of findings. The survey data showed high levels of risk behaviors in both communities, with significantly higher levels of risk reported in Bayamón. Conducting studies of similar ethnic groups in different communities provides opportunities to examine diverse sources of influence on risk behaviors. The integration of qualitative and quantitative methods can enhance comparability and understanding of findings, particularly when there are differences in behaviors between communities.

This article investigates the association between residential status and human immunodeficiency virus (HIV) risk behaviors among island and New York Puerto Rican injection drug users (IDUs). We assigned 561 subjects from New York City and 312 from Puerto Rico to five residential status categories: living in parent's home, living in own home, living in other's home, living in temporary housing (hotel, single-room occupancy [SRO] hotels), and homeless (living in streets/shelters). Dependent variables included injection- and sex-related risk behaviors (sharing syringes, sharing other injection paraphernalia, shooting gallery use, and having paid sex). Chi square, t tests, and multivariate logistic analysis tests were performed separately by site. About one-quarter of the sample in each site was homeless. Island Puerto Ricans were more likely to live with their parents (44% vs. 12%, p < .001), and more New York IDUs lived in their own home (30% vs. 14%, p < .001). In New York, gallery use and paid sex were associated with living in other's home, living in parent's home, and being homeless. Sharing paraphernalia was related to living in other's home, living in temporary housing, and being homeless. In Puerto Rico, having paid sex was associated with homelessness. High-risk behaviors were more likely among homeless IDUs in both sites. Programs to provide housing and target outreach and other prevention programs for homeless IDUs would be helpful in reducing HIV risk.

This study examines the concurrence of drug users' self-reports of current HIV status with serotest results. The analyses are based on data obtained from face-to-face interviews with 7,256 out-of-treatment injection drug and/or crack users in 10 sites that participated in the Cooperative Agreement for AIDS Community-Based Outreach/Intervention Research Program (funded by the U.S. National Institute on Drug Abuse ). Although the degree of concurrence between HIV-negative individuals' self-reports of their current HIV status and their serotest results was high (specificity, 99%), this was not the situation for individuals who tested positive for HIV (sensitivity, 44%).

Frequency of injection has been consistently found to be higher among Puerto Rican Injection drug users (IDUs) than among other groups of IDUs. Several explanations have been suggested, but an empirical explanation has yet to be presented. This study compares the frequency of injection of Puerto Rican IDUs in East Harlem, New York, with that of IDUs in Bayamon, Puerto Rico. Study subjects comprised 521 Puerto Rican IDUs from East Harlem and 303 IDUs from Bayamon. The mean frequency of injection among IDUs in East Harlem was 2.8, the corresponding mean in Bayamon was 5.4. Younger IDUs reported a higher number of daily injection episodes than older IDUs, and the IDU group in Bayamon was 5 years younger than the group in East Harlem. The drug use variables accounted for a greater portion of the between-city difference than the demographic and psychosocial variables. Use of noninjected drugs, as well as the use of prescribed methadone, were found to be associated with a lower number of daily injections. Conversely, injection of cocaine, injection of cocaine mixed with heroin ("speedball"), and injection of larger amounts of drug solution were found to be associated with a higher number of daily injections.

New entrants to methadone maintenance treatment programs (MMTP) have been reported to have different drug use patterns than re-admissions. This study assesses differences between 211 re-admissions and 128 new admissions to a NYC MMTP. Those new to MMTP were found to be less likely to have ever injected drugs, have used more types of drugs, and used heroin at higher frequencies in the 30 days prior to admission. Within the first three months of treatment, new admissions dropped out at a higher rate than the re-admissions (31% vs. 20%, p < 0.05). The most frequent reasons for dropout, for both groups, included "lost to contact" and incarceration. Further research on strategies to address polydrug use of MMTP admissions is needed. Efforts to identify concerns of new admissions early in treatment, and programs to continue drug treatment services to incarcerated clients, are indicated.

This study assessed trends in HIV seroprevalence and needle-sharing behaviors among Puerto Rican injection drug users (IDUs) in Puerto Rico and New York. Data from two studies of IDUs conducted from 1992 through 1995 and 1998 through 1999 in Bayamón, Puerto Rico, and East Harlem, New York, were examined to assess trends over this period. Separate analyses were conducted for IDUs who were current crack smokers. Significant decreasing trends in seroprevalence were found among IDUs in the New York and Puerto Rico samples (p <.001). Significant decreasing trends in receptive and distributive needle sharing were found in the New York sample, and a significant decline in receptive sharing was found in the Puerto Rico sample. Overall, higher levels of needle-sharing behaviors were reported in Puerto Rico compared with New York. Decreasing trends in needle sharing and seroprevalence in both communities are an encouraging finding. Ongoing epidemiologic studies to monitor the epidemic and continued prevention efforts to help maintain or further these declines are needed, particularly to address the higher rates of needle sharing in Puerto Rico.

Time in drug treatment has been shown to be one of the best predictors of post-treatment success. Since as many as half of the enrollees leave methadone treatment during the first year, the project described in this article was designed to test the effectiveness of an alternative program for individuals who have recently dropped out of methadone maintenance treatment. The goals of this "Alternative Program" are to help participants re-connect with formal drug treatment and other community or medical programs, reduce their HIV risk behavior, decrease or eliminate drug use, join self-help groups, and obtain entitlements. Program components include: contacts by local outreach workers, cognitive-behavioral relapse-prevention group counseling, and individual counseling for needs assessment and referral. This paper describes the basis for development of the intervention, summarizes the methodology being used, and provides preliminary data on participation in the Alternative Program.

Many studies have found that the longer a drug user remains in treatment, the more positive the outcome. The majority of studies on the effects of time in treatment have followed subjects from the time they enter treatment. The subjects of the present study are injection drug users and crack users who were out of treatment at the time of their recruitment to the study. Between the initial and six-month follow-up interviews, some chose to enroll in drug treatment. The more time a subject spent in treatment during the follow-up period, the more likely it was that s/he was not using heroin or cocaine at follow-up (OR=.51; 95% C.I., .39-.67; p<.001). Unlike the results of some prior studies, positive effects of time in treatment were found even when time in treatment was less than 90 days. The findings of the present study strongly suggest that treatment is beneficial even for those who remain for less than 90 days. Those who provide treatment services to drug users should attempt to maintain contact with dropouts, and support their return to treatment.

As AIDS cases among US women continue to increase, a better understanding of women's behavioural risk patterns is needed to inform intervention efforts. Data were from 2,945 women drug injectors and crack users. Statistical analyses compared sociodemographic variables, lifetime behavioural risk patterns, HIV sero-prevalence and history of sexually transmitted diseases, and determined predictors of HIV infection separately in 16 low and four high sero-prevalence sites. Based on risk patterns, four behaviourally-defined sub-groups were constructed, and rates of HIV sero-prevalence were compared. In comparisons between low and high sero-prevalence sites, there were significant differences on most variables examined, and in the relative importance of the sociodemographic characteristics and risk patterns predicting HIV. Drug injection and sex exchange were each independent, significant, behavioural predictors of infection, with no significant difference between the odds ratios attributed to each predictor. HIV sero-prevalence was significantly different among four sub-groups. Interventions must be tailored to address observed differences among women in low and high sero-prevalence sites. Injection drug use and exchanging sex each play a major role in the transmission of HIV infection to US women. Prevention efforts targeted at women should address differences in behavioural risk patterns. Aggressive and innovative interventions are needed for women who exchange sex. AIDS research must investigate how socioeconomic factors impact women's risk for HIV infection.

OBJECTIVES: We assessed recent (1992-1997) HIV incidence in the large HIV epidemic among injection drug users in New York City. METHODS: Data were compiled from 10 separate studies (N = 4979), including 6 cohort studies, 2 "repeat service user" studies, and 2 analyses of voluntary HIV testing and counseling services within drug treatment programs. RESULTS: In the 10 studies, 52 seroconversions were found in 6344 person-years at risk. The observed incidence rates among the 10 studies were all within a narrow range, from 0 per 100 person-years at risk to 2.96 per 100 person-years at risk. In 9 of the 10 studies, the observed incidence rate was less than 2 per 100 person-years at risk. The weighted average incidence rate was 0.7 per 100 person-years at risk. CONCLUSIONS: The recent incidence rate in New York City is quite low for a high-seroprevalence population of injection drug users. The very large HIV epidemic among injection drug users in New York City appears to have entered a "declining phase," characterized by low incidence and declining prevalence. The data suggest that very large high-seroprevalence HIV epidemics may be "reversed."

One hundred fifty-eight drug users received an interview that included self-reported drug use. Opiate/cocaine use in the prior 48 hours was assessed by urinalysis. Fifty-five subjects received a urine test after the interview and 103 were tested before. Chi-square tests were performed to determine if agreement between self-reported drug use and urine test results was associated with timing of urine testing. The rate of agreement was 58% when the urine test was performed after the interview and 93% when performed before the interview (chi2 = 28.6, p < .001). Conducting urine tests before an interview can increase the accuracy of self-reports.

Crack cocaine users are at high risk for HIV, with higher frequency crack users engaging in higher rates of HIV-related sexual risk behaviors. This study will assess the variables impacting changes in crack use frequency. Out-of-treatment crack users were street recruited in East Harlem, NY. Subjects (n = 727) were 33% female, 91% minority, and 28% reported recent drug injecting. Baseline and 6-month follow-up interviews were administered. There was a significant reduction in crack use over time (p < .0001). Subjects were categorized according to five groups, based on their change in level of crack use between the two interviews, to predict those who stopped, maintained, or changed their level of use. Discriminant analyses identified six variables as the best predictors of the five groups, including having been in drug treatment since baseline and having been a drug injector (both related to reduced levels of crack use). The overall reduction in crack use for the sample masked the fact that important subgroups remained at high use levels or increased their use. The identification of subgroups who may be most resistant to reducing drug use can be helpful in developing more effective interventions.

OBJECTIVES: This study assessed the relation between year of recruitment into an AIDS prevention project and likelihood of engaging (yes/no) in injection risk behaviors. METHODS: In total, 834 injection drug users were recruited over a 44-month period (January 1992-August 1995) in New York City. Logistic regression was used to examine trends in three behaviors, across four successive annual cohorts: using needles/syringes that were previously used by another person, using injection supplies (e.g., cookers, cotton, rinse water) that had been previously used, and giving or lending of used needles/syringes to another person. RESULTS: Significant (p < .0001) decreasing trends occurred in two behaviors: giving or lending of used needles/syringes to another person and use of injection supplies that had been used by another person. Sample characteristics were generally consistent over time and did not obviate significant injection risk trends. CONCLUSIONS: Decreasing trends in injection risk behaviors could not be explained by changing sample characteristics. Even though some injectors report engaging in risky injection practices, the confluence of numerous AIDS prevention efforts in the 1990s has contributed to an overall reduction in the likelihood of such behaviors.

Focus groups and individual structured interviews were conducted in six cities with 98 predominantly street-recruited men who had a recent history of smoking crack or injecting drugs and who reported having had sex with other men (MSM) in the past year. Twenty-six focus groups explored the cultural and social context of participant's drug use and sexual activity and addressed outreach and HIV prevention issues pertinent to this population. Narrative summaries developed from verbatim focus group transcripts identified seven themes: (a) sexual orientation and gender identity; (b) interactions within and between MSM networks; (c) drug use, sexual activity and personal relationships; (d) HIV transmission bridges; (e) preferred HIV information sources; (f) HIV knowledge, prevention practices and risk behaviours; and (g) availability of HIV and drug-related services. Of the 98 MSM drug users, 42% identified publicly as gay or homosexual; 35% identified publicly, but only 21% privately, as heterosexual. A total of 51% had one or more female sex partners in the past year. There was a high frequency of unprotected sex in conjunction with drug use and a distinct preference for having sex when high. For most participants, drug use rather than sexual orientation formed the core of personal identity. Participants reported associating primarily with other drug users, usually MSM, and had limited contact with people who did not use drugs and the mainstream gay community. Participants' sexual and drug-injecting activities were judged to be a bridge for transmission of HIV to both people who used drugs and those who did not.

OBJECTIVES: This study assessed recent trends in HIV seroprevalence among injecting drug users in New York City. METHODS: We analyzed temporal trends in HIV seroprevalence from 1991 through 1996 in 5 studies of injecting drug users recruited from a detoxification program, a methadone maintenance program, research storefronts in the Lower East Side and Harlem areas, and a citywide network of sexually transmitted disease clinics. A total of 11,334 serum samples were tested. RESULTS: From 1991 through 1996, HIV seroprevalence declined substantially among subjects in all 5 studies: from 53% to 36% in the detoxification program, from 45% to 29% in the methadone program, from 44% to 22% at the Lower East Side storefront, from 48% to 21% at the Harlem storefront, and from 30% to 21% in the sexually transmitted disease clinics (all P < .002 by chi 2 tests for trend). CONCLUSIONS: The reductions in HIV seroprevalence seen among injecting drug users in New York City from 1991 through 1996 indicate a new phase in this large HIV epidemic. Potential explanatory factors include the loss of HIV-seropositive individuals through disability and death and lower rates of risk behavior leading to low HIV incidence.

In developing HIV prevention efforts, it is critical to determine whether interventions are effective in achieving declines in risk behavior among both HIV-positive and HIV-negative individuals. Based on a multisite intervention study of injection drug users (IDUs) and crack smokers, 488 seropositive IDUs and 364 seropositive crack users were compared with randomly selected matched samples of seronegatives (with matching based on recruitment site, gender, age group and ethnicity) at baseline and six-month follow-up to compare changes in risk behaviors by serostatus. Results indicated that overall, risk behaviors declined substantially over time; significant interaction effects indicated that seropositives reported a greater decline in sex risk behaviors than seronegatives. These data support the utility of HIV testing for high-risk drug users, and indicate that interventions have produced reductions in risk behaviors of both seropositives and seronegatives. Further research on the impact of site seroprevalence, and to enhance our understanding of those who continue to engage in risky behaviors, is needed.
