Objective. To explore the association among HIV status; negative psychological symptoms (anxiety, depression, and hostility); and risky sexual behaviors (multiple sexual partners and unprotected sexual intercourse) in a Chilean sample of men who have sex with men (MSM). Methods. This study had a cross-sectional design and a sample of 325 MSM whose ages ranged from 18 to 64 years (mean: 30.8; standard deviation: 9.8). Association tests (chi-squared) and group mean comparisons (Student's t-tests and F-tests) were performed. Results. No statistically significant differences were found for condom use or for the number of sexual partners between HIV-positive men and those who are not infected. In both groups, about 50% reported sexual encounters without condom use in the past six months. There were statistically significant differences in symptoms associated with depression between the two groups. Conclusions. These results reveal the need to strengthen messages about the importance of condom use, as the only way to prevent HIV, and as a means of preventing HIV infection and reinfection, in national prevention and self-care programs for sexually active subjects. More studies are needed in Latin America to advance HIV prevention efforts for the MSM population. The data generated by this study can be used to inform the development of HIV prevention programming strategies and interventions targeting the MSM population in Latin America.

Objectives. To describe patients' suggestions on improving the management of antiretroviral therapy (ART) and to identify the roles that key stakeholders should play in taking responsibility for those recommendations. Methods. This research was embedded within a national cross-sectional study on patient adherence to ART and the associated factors. A subsample of the study patients were asked to offer suggestions on how to improve daily management of ART, and their answers were analyzed using a content analysis approach. The recommendations were then interpreted in terms of who should be responsible for them, and the suggestions were organized into three levels: micro (patient), meso (health care team), and macro (researchers, policymakers, family, friends, and the general public). Results. Of the 552 participants from the subsample, 60% were male, their average age was 44.1 years, and 62% were nonadherent in at least at one of three dimensions (missing doses, improper timing, or improper dosing). The categories underlying the micro level were "believing in treatment efficacy," "being motivated," "accepting HIV status," and "sharing experiences with other patients." At the meso level the suggestion categories were "more information from health care providers" and "humanization of care." The macro level categories were "social support and actions against stigma," "research proposals," and "improvement of health care services." Conclusions. Patients are influenced by the health policies, care, and support offered by health care providers, organizations, policymakers, and communities. In turn, these stakeholders develop the policies and deliver their care and support based on the responses and actions of patients. All stakeholders should work together to engage, educate, and support patients in addressing ART management. [ABSTRACT FROM AUTHOR]

Objective: To highlight the current context of the HIV response in the Caribbean and what remains to be addressed to close gaps in HIV treatment and care and end AIDS by 2030. Methods: We reviewed and analyzed reports from peer-reviewed and gray literature for the period of 2005-2015 on HIV treatment progress and gaps in the Caribbean, based on searches done in four bibliographic databases and three organizations' websites and/or libraries. Data were extracted using forms detailing study objectives, thematic areas for HIV care and treatment in the Caribbean, results, and other key information. Before being included in the descriptive review, each publication was assessed for its relevance to the HIV response in the Caribbean. Results: We carefully analyzed a total of 62 sources addressing HIV treatment coverage in the Caribbean, including peer-reviewed articles, gray literature reports, and abstracts. The Caribbean has made remarkable progress in reducing new infections and in increasing health care access. Coverage with antiretroviral (ARV) treatment rose between 2005 and 2015, and HIV-related mortality fell by half. Despite the decline in HIV incidence rates, some Caribbean countries have reported challenges with linkages to care, access and adherence to ARV treatment, and viral suppression. Conclusion: The risk of HIV infection in the Caribbean among at-risk populations, including men who have sex with men, transgender persons, and sex workers, is disproportionately high. Caribbean countries need to work together to face the HIV threat. National programs need to fast-track HIV treatment services and accelerate other responses to HIV by 2020, and then maintain sustained actions up through 2030. [ABSTRACT FROM AUTHOR]

Men who have sex with men (MSM) can reduce their risk of acquiring human immunodeficiency virus (HIV) by using various prevention strategies and by understanding the effectiveness of each option over the short- and long-term. Strategies examined were: circumcision; insertive anal sex only; consistent, 100% self-reported condom use; and pre-exposure prophylaxis (PrEP). PrEP efficacy was based on three levels of adherence. The cumulative HIV acquisition risk among MSM over periods of 1 year and 10 years were estimated with and without single and combinations of prevention strategies. A Bernoulli process model was used to estimate risk. In the base case with no prevention strategies, the 1-year risk of HIV acquisition among MSM was 8.8%. In contrast, the 1-year risk associated with circumcision alone was 6.9%; with insertive sex only, 5.5%; with 100% self-reported condom use, 2.7%; and with average, high, and very high PrEP adherence, 5.1%, 2.5%, and 0.7%, respectively. The 10-year risk of HIV acquisition among MSM with no prevention strategy was 60.3%. In contrast, that associated with circumcision alone was 51.1%; with insertive sex only, 43.1%; with 100% self-reported condom use, 24.0%; and with average, high, and very high PrEP adherence, 40.5%, 22.2%, and 7.2%, respectively. While MSM face substantial risk of HIV, there are now a number of prevention strategies that reduce risk. Very high adherence to PrEP alone or with other strategies appears to be the most powerful tool for HIV prevention. [ABSTRACT FROM AUTHOR]

Objective. Interpret perceptions of Colombian health professionals concerning factors that obstruct and facilitate the introduction of rapid syphilis and HIV testing in prenatal care services. Methods. A qualitative study based on semi-structured interviews was carried out. A convenience sample was selected with 37 participants, who included health professionals involved in prenatal care services, programs for pregnant women, clinical laboratories, and directors of health care units or centers, as well as representatives from regional departments and the Ministry of Health. Results. Colombia does not do widespread screening with rapid syphilis and HIV tests in prenatal care. The professionals interviewed stated they did not have prior experience in the use of rapid tests--except for laboratory staff--or in the course of action in response to a positive result. The insurance system hinders access to timely diagnosis and treatment. Health authorities perceive a need to review existing standards, strengthen the first level of care, and promote comprehensive prenatal care starting with contracts between insurers and health service institutional providers. Participants recommended staff training and integration between health-policymaking and academic entities for updating training programs. Conclusions. The market approach and the characteristics of the Colombian health system constitute the main barriers to implementation of rapid testing as a strategy for elimination of mother-to-child transmission of syphilis and HIV. Measures identified include making changes in contracts between insurers and health service institutional providers, adapting the timing and duration of prenatal care procedures, and training physicians and nurses involved in prenatal care.

Objective. To evaluate novel eligibility criteria and outreach methods to identify and recruit women at high risk of HIV-1 infection in the Caribbean. Methods. A prospective cohort study was conducted in 2009-2012 among 799 female commercial sex workers in the Dominican Republic, Haiti, and Puerto Rico. Minimum eligibility criteria included exchange of sex for goods, services, or money in the previous 6 months and unprotected vaginal or anal sex with a man during the same period. Sites used local epidemiology to develop more stringent eligibility criteria and recruitment strategies. Participants were asked questions about HIV/AIDS and their level of concern about participating in an HIV vaccine trial. Logistic regression modeling was used to assess predictors of prevalent HIV infection and willingness to participate in a future HIV vaccine study. Results. HIV prevalence at screening was 4.6%. Crack cocaine use [odds ratio (OR) = 4.2, 95% confidence interval (CI) (1.8-9.0)] was associated with and having sex with clients in a hotel or motel [OR = 0.5, CI (0.3-1.0)] was inversely associated with HIV infection. A total of 88.9% of enrolled women were definitely or probably willing to participate in a future HIV vaccine trial. Conclusions. This study indicated that local eligibility criteria and recruitment methods can be developed to identify and recruit commercial sex workers with higher HIV prevalence than the general population who express willingness to join an HIV vaccine trial.

Objective. To compare the sensitivity and specificity of an Oral Rapid Test (ORT) to that of the Enzyme-Linked Immunosorbent Assay (ELISA) for HIV testing in Santiago, Chile; to track the number of study participants returning for ELISA testing results; and to analyze the participants' perceptions of the ORT compared to the ELISA. Methods. A total of 497 people were recruited in Santiago, Chile: 153 had previously tested positive for HIV, and 344 were of unknown status. Participants were tested for HIV using both the ELISA and the ORT to examine and compare specificity and sensitivity. Qualitative data were collected from 22 participants to compare perceptions of the testing experience with ORT versus ELISA. Results. The ELISA reported 184 (37%) of the 497 participants as being "positive" for HIV antibodies; the ORT showed 181 (36.4%) as being "reactive" for HIV. The ORT showed a sensitivity of 98.4% (95.7%--99.9%, 95% Confidence Interval) and specificity of 100%. The Kappa test produced K = 0.983 (P < 0.0001). Of the 344 participants whose HIV status was unknown at the start of the study, 55 failed to return for their ELISA results. Participants positively perceived ORT as having reduced both waiting time and anxiety over obtaining their test results. ORT oral swabbing appeared more practical and less invasive than drawing blood for the ELISA. Conclusions. The ORT and ELISA were statistically equal in specificity and sensitivity. ORT provides quicker results, potentially ensuring that more people receive them, and does not require handling of or exposure to potentially hazardous blood products. [ABSTRACT FROM AUTHOR]

Objective. To compare distributions of human rights violations and disease risk; to juxtapose these patterns against demographic and structural environmental variables, and to formulate implications for structural interventions. Methods. Female sex workers who inject drugs were surveyed in Tijuana and Ciudad Juarez, Mexico. Structured interviews and testing for sexually transmitted infections (STIs) were conducted (October 2008 to October 2009). Frequencies of individual and environmental factors, including police abuse, risk of HIV infection, and protective behaviors, were compared between sites using univariate logistic regression. Results. Of 624 women, almost half reported police syringe confiscation despite syringes being legal; 55.6% reported extortion (past 6 months), with significantly higher proportions in Ciudad Juarez (P < 0.001). Reports of recent solicitation of sexual favors (28.5% in Tijuana, 36.5% in Ciudad Juarez, P = 0.04) and sexual abuse (15.7% in Tijuana, 18.3% in Ciudad Juarez) by police were commonplace. Prevalence of STIs was significantly lower in Tijuana than in Ciudad Juarez (64.2% and 83.4%, P < 0.001), paralleling the lower prevalence of sexual risk behaviors there. Ciudad Juarez respondents reported significantly higher median number of monthly clients (6.8 versus 1.5, P < 0.001) and lower median pay per sex act (US$ 10 versus US$ 20, P < 0.001) (in the past month). Relative to Tijuana, security deployment, especially the army's presence, was perceived to have increased more in Ciudad Juarez in the past year (72.1% versus 59.2%, P = 0.001). Conclusions. Collateral damage from police practices in the context of Mexico's drug conflict may affect public health in the Northern Border Region. Itinerant officers may facilitate disease spread beyond the region. The urgency for mounting structural interventions is discussed. [ABSTRACT FROM AUTHOR]

Latino communities continue to grow in the United States. These communities are significantly affected by HIV infection. New Orleans is a city whose demographics have changed since Hurricane Katrina in 2005, as numerous Latinos/Hispanics came to the city to help rebuild it. This population might have a higher risk of HIV acquisition and problems with access to health care. Data on HIV infection in these populations are insufficient. Active community participation and commitment of key stakeholders are important for developing strategies to bring about change. Political and social support is also a major determinant of any potential change. The following were common ground points after meetings with key stakeholders: (1) to analyze and diagnose health situations in documented and undocumented communities with HIV/AIDS in the city of New Orleans; (2) to develop partnerships and networks among stakeholders with a significant presence in Latino/Hispanic communities in the city; (3) to strengthen research in Latino/Hispanic community issues among research centers, academicians, and health care services; (4) to investigate the development of prevention strategies and technical innovations; (5) to advocate strategies to improve health care access among documented and undocumented immigrants. This project will report additional findings soon. [ABSTRACT FROM AUTHOR]

Objectives. To strengthen prevention of mother-to-child HIV transmission (pMTCT) program implementation in La Romana (LR) province, by estimating HIV prevalence and identifying characteristics associated with HIV infection in parturients. Methods. Umbilical cord blood samples were collected at seven obstetrical sites where over 95% of LR's deliveries occur during four phases (pilot, expanded pilot, full study, and pMTCT program monitoring) from 2 August 2002 to 30 September 2006. Results were linked to data abstracted from delivery records. Results. HIV seroprevalence was 2.6% (263/10 040 overall; 114/4 452, full-study phase (95% confidence interval== 2.1%-3.1%)). Most HIV-infected parturients were Dominican (68.9%) and urban (64.0%). However, prevalence was higher among Haitians (3.7%) than Dominicans (2.3% (p < 0.001)), especially those aged 21-25 years (5.2% vs. 2.3% (p < 0.001)), and among rural, batey, and peri-urban (vs. urban) parturients (3.4% vs. 2.3%, (p = 0.003)). HIV prevalence was associated with commercial sex work (reported by only 0.4%), and prior pregnancy. In logistic regression analysis, commercial sex work, Haitian nationality, and prior pregnancy were independently associated with HIV infection. Caesarean deliveries were more frequent, and rose in the last years of the study, among HIV seropositives; however, most deliveries among seropositives (57.5%) were vaginal. Conclusions. HIV prevalence among LR parturients was higher than the estimated prevalence in the Dominican Republic (0.8%-1.0%) and, in contrast to past studies, predominantly affected urban Dominicans. HIV prevalence among LR Haitian parturients was higher than among Dominican counterparts and prenatal clinic attendees in Haiti (who had a rate of 3.1%). Consistently implemented, targeted pMTCT interventions are needed. [ABSTRACT FROM AUTHOR]

Objectives. To describe the effectiveness of a program designed to reduce the rate of mother-to-child transmission (MTCT) of HIV at the primary HIV testing and treatment center in Haiti between 1999 and 2004. Methods. All pregnant, HIV-positive women who attended the major HIV testing and treatment clinic in Port-au-Prince, Haiti, between March 1999 and December 2004 were asked to participate in an MTCT prevention program. Of the 650 women who participated, 73.3% received zidovudine (AZT), 2.9% received nevirapine (NVP), and 10.1% received triple-drug therapy when it became available in 2003 and if clinical/laboratory indications were met. Approximately 13.8% received no antiretroviral medication. All participants received cotrimoxazole prophylaxis and infant formula for their children. Kaplan-Meier survival analysis and the log rank test were used to evaluate program impact on child survival. Results. Complete data were available for 348 mother-infant pairs who completed the program to prevent MTCT of HIV. The rate of MTCT in the study was 9.2% (95% CI: 6.14-- 12.24), in contrast to the historical mother-to-child transmission rate of 27% in Haiti. HIV-positive infants were less likely to survive than HIV-negative infants at 18 months of followup (χ² = 19.06, P < .001, log rank test). Infant survival improved with early pediatric diagnosis and antiretroviral treatment. Conclusions. The MTCT prevention program described proved to be feasible and effective in reducing vertical HIV transmission in Haiti. The authors emphasize the need to expand testing, extend services to rural areas, and implement early HIV diagnosis to reduce infant mortality. [ABSTRACT FROM AUTHOR]

Objective. The goal of this study is to describe the sexual practices, drug use behaviors, psychosocial factors, and predictors of unprotected anal intercourse (UAI) in a sample of Hispanic men who have sex with men (MSM) born in Latin American and Caribbean (LAC) countries who currently reside in Miami-Dade County, Florida. Methods. Hispanic MSM (N = 566) recruited from community and Internet venues completed a computer-assisted self-interview assessing sociodemographic factors, drug use, sexual behaviors, and psychosocial factors. We focused on the 470 men who were born in LAC countries, including Puerto Rico. We first examined separately, by country of origin, the sexual practices, drug use behaviors, and psychosocial factors of the sample. We then collapsed the groups and examined the factors associated with UAI in the previous 6 months for the entire sample of Hispanic MSM from LAC countries. Results. In the previous 6 months, 44% of the sample engaged in UAI, and 41% used club drugs. At the multivariate level, psychological distress, higher number of sexual partners, club drug use, HIV-positive status at the time of immigration, and greater orientation to American culture were significantly associated with UAI in the previous 6 months. Conclusion. Many MSM born in LAC countries engage in HIV-related risk behaviors in the AIDS epicenter of Miami-Dade County, Florida. Culturally appropriate interventions should address these risk behaviors in this underserved population. [ABSTRACT FROM AUTHOR]
