RESUMEN

BACKGROUND: Public health organizations have inconsistent recommendations for screening adolescents and young adults for Chlamydia trachomatis and Neisseria gonorrhoeae infections. Guidelines suggest different combinations of anorectal, pharyngeal, and urogenital testing based on age, sex, and sexual activity. Further evaluation of how identity and behaviors impact the anatomic distribution of C. trachomatis and N. gonorrhoeae infection is needed to optimize future screening practices. METHODS: We assessed the positivity of C. trachomatis and N. gonorrhoeae infections at different anatomic sites in a cohort of at-risk sexually active adolescents and young adults aged 12-24 years in New Orleans, Louisiana and Los Angeles, California. Participants were tested for C. trachomatis and N. gonorrhoeae at 3 sites (anorectum, pharynx, and urethral/cervix) every 4 months using self-collected swabs. We stratified anatomic distributions of infection into 4 gender and sexual behavior categories: (1) cisgender men who have sex with men and transgender women (MSMTW); (2) cisgender heterosexual males; (3) cisgender heterosexual females; and (4) gender minorities assigned female at birth. RESULTS: While three-site testing detected all infections, two-site (anorectum and urethra/cervix) testing identified 92%-100% of C. trachomatis or N. gonorrhoeae infections in participants assigned female at birth and cisgender heterosexual males. For MSMTW, two-site anorectal and pharyngeal testing vs single-site anorectal testing increased the proportion of individuals with either infection from 74% to 93%. CONCLUSIONS: Sexual behavior and gender identity may influence detection of C. trachomatis and N. gonorrhoeae infections at specific anatomic testing sites. Testing guidelines should incorporate sexual behavior and gender identity. CLINICAL TRIALS REGISTRATION: NCT03134833.

RESUMEN

The Zero Suicide (ZS) approach to health system quality improvement (QI) aspires to reduce/eliminate suicides through enhancing risk detection and suicide-prevention services. This first report from our randomized trial evaluating a stepped care for suicide prevention intervention within a health system conducting ZS-QI describes 1) our screening and case identification process, 2) variation among adolescents versus young adults; and 3) pandemic-related patterns during the first COVID-19 pandemic year. Between April 2017 and January 2021, youths aged 12-24 with elevated suicide risk were identified through an electronic health record (EHR) case-finding algorithm followed by direct assessment screening to confirm risk. Eligible/enrolled youth were evaluated for suicidality, self-harm, and risk/protective factors. Case finding, screening, and enrollment yielded 301 participants showing suicide risk-indicators: 97% past-year suicidal ideation, 83% past suicidal behavior; 90% past non-suicidal self-injury (NSSI). Compared to young adults, adolescents reported: more past-year suicide attempts (47% vs 21%, p<.001) and NSSI (past 6-months, 64% vs 39%, p<.001); less depression, anxiety, posttraumatic stress, and substance use; and greater social connectedness. Pandemic-onset was associated with lower participation of racial-ethnic minority youths (18% vs 33%, p<.015) and lower past-month suicidal ideation and behavior. Results support the value of EHR case-finding algorithms for identifying youths with potentially elevated risk who could benefit from suicide-prevention services, which merit adaptation for adolescents versus young adults. Lower racial-ethnic minority participation after the COVID-19 pandemic-onset underscores challenges for services to enhance health equity during a period with restricted in-person health care, social distancing, school closures, and diverse stresses.

RESUMEN

BACKGROUND: Both compulsory detoxification treatment and community-based methadone maintenance treatment (MMT) exist for heroin addicts in China. We aim to examine the effectiveness of three intervention models for referring heroin addicts released from compulsory detoxification centers to community methadone maintenance treatment (MMT) clinics in Dehong prefecture, Yunnan province, China. METHODS: Using a quasi-experimental study design, three different referral models were assigned to four detoxification centers. Heroin addicts were enrolled based on their fulfillment to eligibility criteria and provision of informed consent. Two months prior to their release, information on demographic characteristics, history of heroin use, and prior participation in intervention programs was collected via a survey, and blood samples were obtained for HIV testing. All subjects were followed for six months after release from detoxification centers. Multi-level logistic regression analysis was used to examine factors predicting successful referrals to MMT clinics. RESULTS: Of the 226 participants who were released and followed, 9.7% were successfully referred to MMT(16.2% of HIV-positive participants and 7.0% of HIV-negative participants). A higher proportion of successful referrals was observed among participants who received both referral cards and MMT treatment while still in detoxification centers (25.8%) as compared to those who received both referral cards and police-assisted MMT enrollment (5.4%) and those who received referral cards only (0%). Furthermore, those who received referral cards and MMT treatment while still in detoxification had increased odds of successful referral to an MMT clinic (adjusted OR = 1.2, CI = 1.1-1.3). Having participated in an MMT program prior to detention (OR = 1.5, CI = 1.3-1.6) was the only baseline covariate associated with increased odds of successful referral. CONCLUSION: Findings suggest that providing MMT within detoxification centers promotes successful referral of heroin addicts to community-based MMT upon their release.

RESUMEN

Women's disclosure of their HIV serostatus across social network ties was examined in a sample of women living in Los Angeles (n = 234), using multivariate random intercept logistic regressions. Women with disclosure-averse attitudes were less likely to disclose, while women with higher CD4+ counts were significantly more likely to disclose, regardless of relationship type. Relative to all other types of relationships, spouses/romantic partners were greater than four times more likely to be the targets of disclosure. Women were more than 2.5 times more likely to disclose to a given network member if that target provided the woman with social support. Social network members whom women believed to be HIV-positive were more than 10 times more likely to be the targets of disclosure. The implications for how social roles and social identities are manifest in these results are discussed, including the implications such an interpretation has for future prevention research.

RESUMEN

Enacted and perceived HIV stigma was examined among substance-using young people living with HIV (YPLH) in Los Angeles, San Francisco, and New York City (N = 147). Almost all YPLH (89%) reported perceived stigma, and 31% reported enacted experiences in the past 3 months; 64% reported experiences during their lifetime. The HIV stigma questions were characterized by factors of avoidance, social rejection, abuse, and shame. In multivariate models, enacted stigma was associated with gay or bisexual identity, symptomatic HIV or AIDS, and bartering sex. Perceived stigma was associated with female gender, symptomatic HIV or AIDS, bartering sex, lower injection drug use, and fewer friends and family knowing serostatus. Gay or bisexual YPLH who were also HIV symptomatic or AIDS diagnosed experienced more HIV stigma than their heterosexual peers.

RESUMEN

BACKGROUND: Interventions are needed to reduce poor perinatal health. We trained community health workers (CHWs) as home visitors to address maternal/infant risks. METHODS: In a cluster randomised controlled trial in Cape Town townships, neighbourhoods were randomised within matched pairs to 1) the control, healthcare at clinics (n = 12 neighbourhoods; n = 594 women), or 2) a home visiting intervention by CBW trained in cognitive-behavioural strategies to address health risks (by the Philani Maternal, Child Health and Nutrition Programme), in addition to clinic care (n = 12 neighbourhoods; n = 644 women). Participants were assessed during pregnancy (2% refusal) and 92% were reassessed at two weeks post-birth, 88% at six months and 84% at 18 months later. We analysed 32 measures of maternal/infant well-being over the 18 month follow-up period using longitudinal random effects regressions. A binomial test for correlated outcomes evaluated overall effectiveness over time. The 18 month post-birth assessment outcomes also were examined alone and as a function of the number of home visits received. RESULTS: Benefits were found on 7 of 32 measures of outcomes, resulting in significant overall benefits for the intervention compared to the control when using the binomial test (p = 0.008); nevertheless, no effects were observed when only the 18 month outcomes were analyzed. Benefits on individual outcomes were related to the number of home visits received. Among women living with HIV, intervention mothers were more likely to implement the PMTCT regimens, use condoms during all sexual episodes (OR = 1.25; p = 0.014), have infants with healthy weight-for-age measurements (OR = 1.42; p = 0.045), height-for-age measurements (OR = 1.13, p<0.001), breastfeed exclusively for six months (OR = 3.59; p<0.001), and breastfeed longer (OR = 3.08; p<0.001). Number of visits was positively associated with infant birth weight ≥2500 grams (OR = 1.07; p = 0.012), healthy head-circumference-for-age measurements at 6 months (OR = 1.09, p = 0.017), and improved cognitive development at 18 months (OR = 1.02, p = 0.048). CONCLUSIONS: Home visits to neighbourhood mothers by CHWs may be a feasible strategy for enhancing maternal/child outcomes. However, visits likely must extend over several years for persistent benefits. TRIAL REGISTRATION: ClinicalTrials.gov NCT00996528.

RESUMEN

Family environment and rates of mental health and behavioral problems in HIV-negative adolescents and their parents living with HIV (PWH) were compared to adolescents and parents from non HIV-affected families living in similar inner-city neighborhoods. Adolescents and their parents were interviewed and a case-control sample was constructed. Data on sixty-two matched pairs of adolescents of PWH and those of neighborhood parents and forty-six matched pairs of PWH and HIV-negative parents were examined. Compared to neighborhood controls, adolescents of PWH experienced greater life stressors and family conflict and reported lower self-esteem. PWH reported greater emotional distress and substance use. However, there were no significant differences in emotional distress or externalized problem behaviors between the two adolescent groups. Clinical implications are discussed.

RESUMEN

BACKGROUND/AIM: Recipients of orthotopic liver transplant for hepatitis C (HCV) invariably develop recurrent disease. The risk factors for death and retransplantation following the development of cirrhosis from HCV are unclear. The aim of this study was to identify predictors of survival in liver transplant recipients who develop cirrhosis from recurrent HCV. METHODS: We reviewed records of patients who underwent liver transplantation for cirrhosis due to HCV between January 1990 and December 2001. Prognostic factors of patient survival following the development of recurrent cirrhosis were identified through multivariate analysis. RESULTS: During the study period, 511 patients underwent transplantation for HCV cirrhosis. Of these, 65 patients (13%) developed biopsy proven recurrent cirrhosis from HCV; 43 (8%) were relisted for transplantation, and 24 (5%) underwent retransplantation. The overall Kaplan-Meier patient survival rates after the histologic diagnosis of cirrhosis at 1 and 5 years were 66% and 30%, respectively. A multivariate Cox proportional hazards model showed patients with higher last (i.e. at follow-up or prior to retransplantation) International normalized ratio (INR) values (hazard ratios (HR)=2.02, 95% confidence interval 1.26, 3.24, P<0.01) to have an increased risk of death. CONCLUSION: Our results suggested survival was decreased after the diagnosis of cirrhosis from recurrent HCV. Higher INR was associated with an increased risk of death following the development of cirrhosis.

RESUMEN

The use of hepatitis B core antibody (HBcAb)- and hepatitis C virus antibody (HCV+) liver grafts for transplantation in selected populations has not affected patient and graft survival. We reexamined the clinical outcomes of using these HBcAb+ and HCV+ grafts at our institution, in addition to studying recipients of combined HBcAb+/HCV+ grafts. We identified 377 patients who underwent transplantation for either hepatitis B and/or hepatitis C, or received both HBcAb+ and HCV+ grafts. Patient and graft survival at 5 years posttransplantation was 73% and 71%, respectively, in the HBcAb+ grafts compared with 81% and 75% in the HBcAb- grafts (P =.65; P =.94). For HCV+ grafts, patient and graft survival at 5 years posttransplantation was 89% and 73%, respectively, compared with 69% and 59% in the HCV- grafts; (P =.22; P =.77). The 5-year patient and graft survival rate in those who received combined HBcAb+/HCV+ grafts was 74% and 69%, respectively, and there was no statistical difference compared with the HBcAb+ and HCV+ grafts (P =.76; P =.90). The 5-year patient and graft survival rate in patients who received dual HBV prophylaxis with hepatitis B immunoglobulin (HBIg) and lamivudine was 88% and 84%, respectively, which was significantly higher than for patients who received single prophylaxis or no prophylaxis (P <.01; P =.02). Our study supports previous observations that patient and graft survival is not affected with the use of HBcAb+ and HCV+ grafts, and that dual prophylaxis with HBIg and lamivudine offers substantial survival benefits. Furthermore, the use of combined HBcAb+/HCV+ grafts did not impact patient or graft survival. This provides a potential new pool of donor livers that can be used for transplantation in select patients.
