The purpose of this study was to examine patterns and predictors of HIV/STI risk over time among Latino migrant men in a new receiving community. Latino men (N = 125) were interviewed quarterly for 18 months and HIV/STI tested annually. Selected individual, environmental and cultural factors by partner type and condom use were explored longitudinally and in a cross-section. Sex with female sex workers (FSWs) and multiple partners decreased, sex with main partners and abstinence increased, while the number of casual partners remained stable. Consistent condom use was highest with FSWs, lowest with main partners and midrange with casual partners with no trends over time. STI morbidity was low; no HIV was detected. Drug use and high mobility were associated with inconsistent condom use with FSW, whereas having family in the household was protective. HIV/STI prevention efforts should focus on drug using Latino migrants who are highly mobile and should foster healthy social connections. 相似文献

Misconceptions about HIV transmission and prevention may inhibit individuals’ accurate assessment of their level of risk.
We used venue-based sampling to conduct a cross-sectional study of heterosexually active adults (N = 1,221) within areas exhibiting high poverty and HIV/AIDS rates in Miami-Dade and Broward counties in 2007. Two logistic
regression analyses identified correlates of holding inaccurate beliefs about HIV transmission and prevention. Belief in incorrect
HIV prevention methods (27.2%) and modes of transmission (38.5%) was common. Having at least one incorrect prevention belief
was associated with being Hispanic compared to white (non-Hispanic), being depressed, and not knowing one’s HIV status. Having
at least one incorrect transmission belief was associated with being younger, heavy alcohol use, being depressed, not having
seen a physician in the past 12 months, and not knowing one’s HIV status. Among low-income heterosexuals, HIV prevention and
transmission myths are widespread. Debunking them could have HIV prevention value. 相似文献

Objective. To determine whether MPO contributes to oxidative stress and disease activity in RA and whether it produces hypochlorous acid in SF. Methods. Plasma and where possible SF were collected from 77 RA patients while 120 healthy controls supplied plasma only. MPO and protein carbonyls were measured by ELISAs. 3-Chlorotyrosine in proteins and allantoin in plasma were measured by mass spectrometry. Results. Plasma MPO concentrations were significantly higher in patients with RA compared with healthy controls [10.8?ng/ml, inter-quartile range (IQR): 7.2-14.2; P?0.05], but there was no significant difference in plasma MPO protein concentrations between RA patients with high disease activity (HDA; DAS-28 >3.2) and those with low disease activity (LDA; DAS-28 ≤3.2) (HDA 27.9?ng/ml, 20.2-34.1 vs LDA 22.1?ng/ml, 16.9-34.9; P?>?0.05). There was a significant relationship between plasma MPO and DAS-28 (r?=?0.35; P?=?0.005). Plasma protein carbonyls and allantoin were significantly higher in patients with RA compared with the healthy controls. MPO protein was significantly higher in SF compared with plasma (median 624.0?ng/ml, IQR 258.4-2433.0 vs 30.2?ng/ml, IQR 25.1-50.9; P?0.0001). The MPO present in SF was mostly active. 3-Chlorotyrosine, a specific biomarker of hypochlorous acid, was present in proteins from SF and related to the concentration of MPO (r?=?0.69; P?=?0.001). Protein carbonyls in SF were associated with MPO protein concentration (r?=?0.40; P?=?0.019) and 3-chlorotyrosine (r?=?0.66; P?=?0.003). Conclusion. MPO is elevated in patients with RA and promotes oxidative stress through the production of hypochlorous acid. 相似文献
