Workplace-based interventions could improve work disability outcomes for workers with CMHCs. Facilitation of access to clinical treatment, and workplace-based high-intensity psychological intervention were most effective in improving work functioning and quality of life, and in reducing costs.
Human herpesvirus-8 (HHV-8) is frequently detected in oropharyngeal secretions from HIV-infected men who have sex with men (MSM), and contact with saliva may be an important mode of HHV-8 transmission. A total of 196 MSM were followed over 2 years to determine the correlates of HHV-8 oropharyngeal shedding. A total of 134 (68%) of 196 participants were HHV-8 seropositive upon enrollment, and 9 (15%) of 62 participants seroconverted to HHV-8 during follow-up. HHV-8 DNA was detected in 43 (22%) of 196 participants: 39 (27%) of 134 HHV-8 seropositive, 4 (8%) of 53 HHV-8 seronegative, and 5 (56%) of 9 seroconverters to HHV-8. HHV-8 was detected in 101 (15%) of 696 total oral specimens: 84 (17%) of 481 samples from HHV-8-seropositive men, 6 (3%) of 180 samples from HHV-8-seronegative men, and 11 (31%) of 35 samples from seroconverters. Using adjusted marginal structural models, HHV-8 shedding was higher in men not receiving highly active antiretroviral therapy (odds ratio 2.4, 95% CI 1.0-6.0, P = 0.06), with CD4 counts > 200 cells/mm (odds ratio 4.8, 95% CI 1.0-22.8, P = 0.05), or with detectable oral leukocyte esterase (odds ratio 5.0, 95% CI 2.0-12.5, P < 0.01). CD4 count, antiretroviral therapy, and oral inflammation may influence HHV-8 oropharyngeal shedding.
We monitored trends in HIV risk behaviors and seroconversion among out-of-treatment injection drug users (IDUs) receiving street-based outreach intervention. Beginning in 1988, 641 HIV-seronegative IDUs were recruited by targeted sampling methods to reflect broader IDU populations and were followed for 4 years (1988-1992). All were active injectors not in treatment when recruited. Cohort members were targets of HIV-prevention outreach. The intervention was guided by the Indigenous Leader Outreach Model: Exaddicts deliver HIV-prevention services targeting IDU social networks in community settings. Primary outcome measures were HIV seroconversion and HIV risk behaviors. Observed incidence of HIV infection decreased, from 8.4 to 2.4 per 100 person-years. Prevalence of drug risk behaviors also decreased, from 100 to 14%. Seroconversion was associated with injection risk behavior [risk ratio (RR) = 9.8]. Sex risk behavior also decreased, but less dramatically, from 71 to 45%. Out-of-treatment IDUs in Chicago have reduced their rates of new HIV infection by reducing their injection risk behavior. New infections were strongly associated with injection risk behavior but not with sex risk behavior.
Kaposi's sarcoma-associated herpesvirus (KSHV) in oral and genital secretions of women may be involved in horizontal and vertical transmission in endemic regions. Nested polymerase chain reaction assays were used to detect KSHV DNA sequences in one-third of oral, vaginal, and cervical specimens and in 42% of peripheral blood mononuclear cell (PBMC) specimens collected from 41 women infected with human immunodeficiency virus type 1 who had Kaposi's sarcoma (KS). KSHV DNA was not detected in specimens from 100 women without KS, 9 of whom were seropositive for KSHV. A positive association was observed between KSHV DNA detection in oral and genital mucosa, neither of which was associated with KSHV DNA detection in PBMC. These data suggest that KSHV replicates in preferred anatomic sites at levels independent of PBMC viremia. Detection of genital-tract KSHV only among relatively immunosuppressed women may provide an explanation for infrequent perinatal transmission of KSHV.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
