Recent outbreaks of syphilis among men who have sex with men (MSM) in major cities in the United States and reported increases in sexual risk behavior have raised concerns about potential increases in human immunodeficiency virus (HIV) transmission. The majority of MSM who have early syphilis are HIV infected; in preliminary studies, rates of recent HIV infection among them are also high. Data from San Francisco, Los Angeles, and Seattle-King County, however, suggest no temporal increases in HIV incidence among MSM seeking HIV testing at select large public sites during the syphilis outbreaks. Because most HIV incidence and behavioral data are from large metropolitan areas with large gay populations and well-established HIV epidemics, we do not know whether, nationally, incidence of HIV infection among MSM has been increasing, decreasing, or stable during syphilis outbreaks. Further studies of HIV incidence in larger and smaller cities with different maturities of HIV epidemic are warranted. Comprehensive and integrated HIV/STD prevention and control efforts are also needed to halt the spread of syphilis and reduce HIV transmission among gay and bisexual men.

This study investigates cognitive, cultural, and contextual factors that influence HIV-related risk behaviors among Asian women who engage in sex work at massage parlors in San Francisco. Focus groups and qualitative interviews were conducted for Vietnamese and Thai masseuses and massage parlor owners/managers. Economic pressure as well as subjective evaluation of customers for the risk of HIV/STD infection increase unprotected sexual behaviors among Asian masseuses. Massage parlor owners/managers do not establish a clear policy for condom use at their parlors. Consequently, male customers often manipulate their intention not to use a condom while negotiating with masseuses. HIV/STD prevention intervention programs should address specific risks and needs for Asian masseuses, owners/managers, and male customers in order to promote health and well being among Asian masseuses who have been neglected by public health and social services.

Throughout the world, injection drug users (IDUs) are the group at highest risk for hepatitis C virus (HCV) infection. IDUs residing in the island of Puerto Rico and Puerto Rican IDUs residing in the U.S. mainland have been shown to be at very high risk of infection with HIV. However, the extent to which HCV infection has spread among IDUs in Puerto Rico is not yet known. The aims of this study were to estimate seroprevalence of HCV and to identify the correlates associated with HCV transmission. The sample was drawn through street outreach strategies and was comprised of 400 injection drug users not in treatment, living in the San Juan metropolitan area. HCV and HIV infection were detected by enzyme-linked immunosorbent assay and the results were confirmed by Western blot. Information on sociodemographics, drug use patterns, and risk behaviors was obtained through structured interviews. Bivariate analyses and multivariate logistic regression were used to assess covariates of infection with HCV. The prevalence of HCV infection was 89%. After controlling for sociodemographic characteristics, HCV infection was positively associated with increasing years of injection, injecting in a shooting gallery, tattooing in prison, and self-reported STD infection. Notably, IDUs who had initiated drug injection within the year prior to the study interview had an HCV infection rate of 57%. This study indicates that more aggressive educational programs are urgently needed to reduce the spread of HCV infection among IDUs in Puerto Rico.

Slurry sampling electrothermal vaporization (ETV) inductively coupled plasma mass spectrometry (ICP-MS) has been applied to determine As and Se in soil and sludge samples. The influences of instrument operating conditions and slurry preparation on the ion signals were reported. Pd and ascorbic acid were used as mixed modifiers to enhance the ion signals. The effectiveness of ETV sample introduction technique for alleviating various spectral interferences in ICP-MS analysis has been demonstrated. This method has been applied to determine As and Se in NIST SRM 2709 San Joaquin soil reference material and NIST SRM 2781 domestic sludge reference material and a farmland soil sample collected locally. Since the sensitivities of As and Se in slurry solution and aqueous solution were different, analyte addition technique was used to determine As and Se in these samples. The As and Se analysis results of the reference materials agreed with the certified values. The precision between sample replicates was better than 5% for all determinations. The method detection limit estimated from analyte addition curves was about 0.03 and 0.02 microg g(-1) for As and Se, respectively, in original soil and sludge samples.

HIV/AIDS epidemic is crucial in China; however, few studies were performed on youths. This study was performed to examine the effectiveness of peer-led HIV prevention intervention on HIV-related knowledge, attitudes and behaviour intention in senior high-school students in San-ming, a medium-sized city in Fujian province. Three thousand and sixty-eight students completed self-administered questionnaires before and after intervention, of which 981 students (the intervention group) accepted peer-led HIV/AIDS prevention intervention and others (the control groups) continued the usual teacher-led health education curriculum. Significant increases were observed in the intervention group in HIV-related knowledge, in attitudes and in behaviour intention after intervention. The results of this research also indicated an inconsistent level of HIV/AIDS knowledge and attitude among students, with a significant gender, health education history and style difference in session delivery. More concerted efforts in HIV prevention are needed to improve young people's sexual health.

In Central America, nearly 70% of pediatric cancer is related to hemato-oncologic disorders, especially acute lymphoblastic leukemia (ALL). Preliminary studies have described a high incidence of childhood leukemia in these countries; however, no molecular analyses of these malignancies have yet been carried out. We studied diagnostic samples from 84 patients from the National Children's Hospital in San Jose, Costa Rica (65 precursor B-ALL, 5 T-cell ALL, and 14 acute myeloblastic leukemia). Our methodology included cytogenetic, fluorescent in situ hybridization, and polymerase chain reaction approaches. The observed rate of leukemia was 52.2 cases per million children per year. Twelve out of 65 (18.4%) precursor B-ALL tested positive for TEL-AML1 and 3 cases for BCR-ABL (4.6%). In addition, we detected 2 patients carrying an E2A-PBX1 transcript (3.1%) and 1 patient with an MLL-AF4 fusion gene (1.5%). None of the T-cell ALL cases were positive for either SIL-TAL1 or HOX11L2. Within 14 acute myeloblastic leukemia patients, we confirmed 2 cases with FLT3-internal tandem duplication+, 1 patient with AML1-ETO, and only 1 case carrying a PML-RARalpha rearrangement. The present study confirms the relatively high incidence of pediatric leukemia in Costa Rica and constitutes the first report regarding the incidence of the main molecular alterations of childhood leukemia in our region.

The expense in time and money limit the use of randomized clinical trials (RCT) and cohort studies for evaluating long-term AIDS treatment outcomes. We conducted a case-control study to characterize predictors of AIDS mortality after the availability of highly active antiretroviral therapy (HAART) in San Francisco, in which cases were matched with controls on stage of disease, year of AIDS diagnosis and year of HAART initiation. Overall, 266 cases and 1173 controls were included, representing >90% of eligible patients. The class of initial HAART regimen was not associated with mortality. Predictors of mortality were older age ([adjusted odds ratio] AOR 1.23, 95% [confidence interval] CI: 1.13-1.35), public versus private health insurance (AOR 2.80, 95% CI: 1.77-4.42), no versus private insurance (AOR 1.45, 95% CI: 1.02-2.07) and unboosted saquinavir (AOR 2.50, 95% CI: 1.34-4.65). Survival benefit was found in following the 2004 US Department of Health and Human Services preferred treatment guidelines; borderline survival benefits were found in following the guidelines from other years. Similar predictors were found for all-cause and AIDS-specific mortality. Our findings mirrored those of RCT and multi-centre cohort studies, and may be applicable to other settings. Our findings support similar survival benefit to persons initiating HAART with non-nucleoside reverse transcriptase inhibitor- or protease inhibitor-based regimens.

The presence of the JAK2 V617F mutation is now part of clinical diagnostic algorithms, and JAK2 status is routinely assessed when BCR/ABL- chronic myeloproliferative neoplasms (MPNs) are suspected. The aim of this study was to evaluate performance of 3 screening and 1 quantitative method for JAK2 V617F detection. For the study, 43 samples (27 bone marrow aspirates and 16 peripheral blood samples) were selected. The screening assays were the JAK2 Activating Mutation Assay (InVivoScribe, San Diego, CA), JAK2 MutaScreen kit (Ipsogen, Luminy Biotech, Marseille, France), and a home-brew melting curve analysis method. Ipsogen's JAK2 MutaQuant assay was used for quantification of mutant and wild-type alleles. The limit of detection was 1% for the kit-based screening methods and 10% for the melting curve method. The JAK2 MutaQuant assay demonstrated analytic sensitivity of 0.01%. All 4 methods detected cases of BCR/ABL- MPNs and gave negative results with BCR/ABL+ chronic myelogenous leukemia, multiple myeloma, myelodysplastic syndrome, and normal cases.

Rectal gonorrhea cases among males remained stable in San Francisco during 2005-2008, but rectal chlamydia increased 38 percent. While testing increased, rectal gonorrhea positivity declined at the STD clinic, and both infections remained stable elsewhere. Sentinel surveillance provides a better understanding of disease trends than case reporting alone.
