“…This is of particular concern because previous research suggests that substance use may inhibit disclosure practices by HIV-positive MSM (Semple et al, 2006) and increase the likelihood of unsafe sex without disclosure (Marks and Crepaz, 2001;Purcell et al, 2005). These fi ndings may be the result of the portal survey methodology used in the current study, which is intended to provide more generalizable results than past studies (of different populations) that have relied largely on samples of convenience (see Johnson et al, 2006;Kelley-Baker et al, 2007;Lange et al, 1999;Voas et al, 2006).…”

ABSTRACT. Objective: This study examined substance use (intended and actual), unprotected sex, and HIV disclosure practices (disclosure and questioning) among HIV-positive men who have sex with men (MSM) at two party-oriented vacations, where substance use and sexual risk may be heightened. Method: A random sample of 489 MSM attending one of two party-oriented vacations participated in PartyIntents, a short-term longitudinal survey. Nearly half (47%) completed a follow-up assessment at the event or online for up to 2 weeks after the event. We examined rates of baseline intentions to use substances, actual substance use, and unprotected intercourse among HIV-positive men in attendance. Rates among HIV-negative men were estimated for comparison. Multiple logistic regression was used to assess the impact of illegal drug use and HIV status on unprotected anal intercourse (UAI). Results: HIV-positive attendees (17%) were signifi cantly more likely than HIV-negative attendees to use nitrite inhalants (or "poppers") (24.3% vs. 10.7%). HIVpositive attendees were also signifi cantly more likely to have insertive UAI (64.3% vs. 34.1%) and receptive UAI (68.8% vs. 22.2%). Multivariate models showed associations between HIV status and illegal drug use with UAI (for HIV status, odds ratio [OR] = 4.5, p = .001; for any illegal drug use, OR = 16.4, p < .001). There was no evidence that the infl uence of drug use moderated risk by HIV status. Rates of HIV disclosure and questioning did not differ by HIV status. Conclusions: HIV-positive men attending these events engaged in higher rates of illegal drug use and sexual risk than HIV-negative men. Prevention campaigns targeting MSM at high-risk events should include messages geared toward HIVpositive men. (J. Stud. Alcohol Drugs, 74, 158-167, 2013)

“…The San Diego-Tijuana binational region, however, shares one of the busiest border crossings in the United States with Baja, Mexico (28), where M. bovis is prevalent in cattle and consumption of unpasteurized dairy products is a common cultural practice (29)(30)(31)(32). Mexican dairy products, including the popular queso fresco (soft, unpasteurized cheese), may be brought into the United States for personal use and are sometimes distributed illegally (27).…”

The epidemiology of tuberculosis (TB) in the United States is changing as the incidence of disease becomes more concentrated in foreign-born persons. Mycobacterium bovis appears to be contributing substantially to the TB incidence in some binational communities with ties to Mexico. We conducted a retrospective analysis of TB case surveillance data from the San Diego, California, region from 1994 through 2005 to estimate incidence trends, identify correlates of M. bovis disease, and evaluate risk factors for deaths during treatment. M. bovis accounted for 45% (62/138) of all culture-positive TB cases in children (<15 years of age) and 6% (203/3,153) of adult cases. T he pattern of tuberculosis (TB) in the United States is changing as the incidence of TB disease becomes more concentrated in foreign-born persons. Of the annual total US TB cases, >54% are now concentrated in persons born outside of the United States (1); in communities with high immigration, the proportion can exceed 70% (2). TB prevention and treatment strategies, particularly those in communities on the border with Mexico, will need to be adapted to accommodate the changing epidemiology of TB (3).San Diego, California, together with its sister city Tijuana-Tecate, Mexico, is the largest binational metropolitan region in the United States, accounting for 34% of the southern border population (4). In San Diego County, the Hispanic population has grown from 20% to 29% in the past 15 years (5). Of the total annual TB cases in San Diego, >70% occurred among foreign-born persons, of whom nearly half originated from Mexico (2). A review of culture-positive TB cases in San Diego County in the late 1990s indicated that 6.6% of all adult TB cases and 39% of all pediatric (<15 years of age) TB cases from this region were not caused by Mycobacterium tuberculosis, the most common TB pathogen in the United States, but were instead caused by M. bovis, a pathogen more often associated with TB in cattle (6). This fi nding represented the highest reported proportional incidence of TB from M. bovis among industrialized countries (7).M. bovis is a pathogen in the complex of bacteria that includes M. tuberculosis, which causes TB in humans and animals. TB from M. bovis has been generally considered rare in the United States after its successful eradication from cattle in the mid-1900s (8), but wider use of laboratory tools for species-level diagnosis of TB pathogens has started to shed light on an unexpected regional presence of M. bovis in communities with large Hispanic populations. While M. bovis TB has been most often documented in Hispanic communities with close proximity to Mexico (6,9), a recent review of M. bovis cases in New York City indicates that the problem is not limited to US regions that border Mexico (10).The clinical and pathologic characteristics of M. bovis TB is indistinguishable from M. tuberculosis TB in most cases, but there are relevant considerations for prevention and treatment strategies in communities where M. bovis contributes to TB incid...

“…A larger body of literature has emerged which has examined cross-border drinking in the US/Mexican context. The research indicates that this border region has widely established and problematic alcoholrelated behaviours among young adults (Clapp et al, 2001;Lange et al, 1999;Lange and Voas, 2001;Voas et al, 2002aVoas et al, , 2002b. Specifically, an estimated 1000 US San Diegans return from Tijuana, Mexico, every hour between midnight and 5:00 a.m. after drinking (Baker et al, 2000).…”

Purpose-This study evaluated the cross-border safety impact of extended drinking hours from 1:00 to 2:00 a.m., in licensed establishments in Ontario, Canada.Methods-This study examined patterns in total and alcohol-related casualties in: (1) Windsor, Ontario, Canada compared to Detroit, Michigan, US with a 2:00 a.m. closing time, and (2) Ontario compared to Michigan for overall trends. The criterion outcome indicators were: (1) monthly motor vehicle casualties (major injuries and fatalities) for the city-regions of Windsor and Detroit and (2) Ontario and Michigan monthly motor vehicle fatalities occurring between 11:00 p.m. and 3:00 a.m. for 4 years pre-and 3 years post-policy change. In order to examine cross-border drinking consequences, data were disaggregated to assess trends of motor vehicle injury collisions involving vehicles with US licence plates and with US drivers aged 16-20 in the Windsor region; similarly trends were assessed for motor vehicle injury collisions involving vehicles with Ontario licence plates in the Detroit region.Results-The Windsor region total motor vehicle casualty data showed a non-significant pre-post increase, while the Detroit region showed a statistically significant decrease for total motor vehicle casualties. In the Windsor region, a significant increase was found for alcohol-related motor vehicle casualties after the drinking hours were extended. However, the Detroit region showed a statistically significant decrease in alcohol-related motor vehicle casualties concomitant with Ontario's drinking hour extension. No similar trends were found for the province of Ontario and the state of Michigan as a whole. Moreover, a significant decrease was found for injury collisions involving vehicles with Ontario licence plates in the Detroit region but no similar pattern was found for injury collisions involving vehicles with US licence plates and with 16-20-year-old US drivers in the Windsor region.Discussion-These data seem to support a cross-border impact of the Ontario extended drinking policy. A significant increase in alcohol-related motor vehicle casualties was found in the Windsor region and concomitantly, significant decreases in total and alcohol-related motor vehicle casualties were found in the Detroit region after the extended drinking hours amendment.
