BackgroundCannabis use and cannabis regulatory policies recently re-surfaced as noteworthy global research and social media topics, including claims that Mexicans have been sending cannabis and other drug supplies through a porous border into the United States. These circumstances prompted us to conduct an epidemiological test of whether the states bordering Mexico had exceptionally large cannabis incidence rates for 2002–2011. The resulting range of cannabis incidence rates disclosed here can serve as 2002–2011 benchmark values against which estimates from later years can be compared.MethodsThe population under study is 12-to-24-year-old non-institutionalized civilian community residents of the US, sampled and assessed with confidential audio computer-assisted self-interviews (ACASI) during National Surveys on Drug Use and Health, 2002–2011 (aggregaten ∼ 420,000) for which public use datasets were available. We estimated state-specific cannabis incidence rates based on independent replication sample surveys across these years, and derived meta-analysis estimates for 10 pre-specified regions, including the Mexico border region.ResultsFrom meta-analysis, the estimated annual incidence rate for cannabis use in the Mexico Border Region is 5% (95% CI [4%–7%]), which is not an exceptional value relative to the overall US estimate of 6% (95% CI [5%–6%]). Geographically quite distant from Mexico and from states of the western US with liberalized cannabis policies, the North Atlantic Region population has the numerically largest incidence estimate at 7% (95% CI [6%–8%]), while the Gulf of Mexico Border Region population has the lowest incidence rate at 5% (95% CI [4%–6%]). Within the set of state-specific estimates, Vermont’s and Utah’s populations have the largest and smallest incidence rates, respectively (VT: 9%; 95% CI [8%–10%]; UT: 3%; 95% CI [3%–4%]).DiscussionBased on this study’s estimates, among 12-to-24-year-old US community residents, an estimated 6% start to use cannabis each year (roughly one in 16). Relatively minor variation in region-wise and state-level estimates is seen, although Vermont and Utah might be exceptional. As of 2011, proximity to Mexico, to Canada, and to the western states with liberalized policies apparently has induced little variation in cannabis incidence rates. Our primary intent was to create a set of benchmark estimates for state-specific and region-specific population incidence rates for cannabis use, using meta-analysis based on independent US survey replications. Public health officials and policy analysts now can use these benchmark estimates from 2002–2011 for planning, and in comparisons with newer estimates.

AbstractConcrete biodeterioration is defined as the damage that the products of microorganism metabolism, in particular sulfuric acid, do to hardened concrete. In Canada and in the northern part of the United States, sewer failures from concrete biodeterioration are almost unknown. In the southern part of the United States and in Mexico, however, it is a serious and expensive problem in sewage collection systems, which rapidly deteriorate. Also, leaking sewage systems result in the loss of groundwater resources particularly important in this arid region. Almost every city in the Mexican-American border region, who's combined population is more than 15 million people, faces this problem. The U.S. cities have made some provision to face these infrastructure problems, but the Mexican cities have made less effort. We recommend here the Mexican norm (NMX-C-414-ONNCCE-2004) [1] to be reviewed, or at least that a warning be issued as a key measure to avoid concrete biodeterioration.

Abstract Objective HIV-associated neurocognitive impairment (NCI) is prevalent and impactful. Yet, there is an absence of published studies that investigate its correlates among Spanish-speaking Latinos living in mainland US- a demographic that represents a large and vulnerable segment of the HIV+ population. The goal of the current study was to examine predictors of NCI among Spanish-speaking Latinos with HIV living in the United States. Participants and Method 153 Spanish-speaking Latinos living with HIV from the US-Mexico border region (Age: M = 38.2, SD = 9.7; Education: M = 10.9, SD = 3.6; 73% female; 56% AIDS) completed comprehensive neuropsychological, neuromedical, and psychiatric evaluations in Spanish. Scores across 7 cognitive domains were converted to a Global Deficit Score (GDS) based on T-scores on individual tests using newly developed, region specific, and demographically-corrected norms for Spanish-speaking Latinos. NCI was determined using cutoff of GDS > 0.5 (39.2% of sample). Examined predictors included HIV disease characteristics (e.g., AIDS status, current CD4 count, duration of antiretroviral therapy (ART) exposure) and psychiatric comorbidities. Results A multivariable logistic regression - including predictors that were associated with NCI in univariable analyses - showed a significant interaction between lifetime history of substance use disorder (LT SUD) and duration of ART exposure, after accounting for AIDS status (LR Chi2 = 3.99, p = 0.046). Stratified analyses showed that among participants who did not have LT SUD, longer ART exposure was associated with decreased NCI (p = 0.01), while rates of NCI among those with LT SUD were not influenced by months of ART exposure (p = 0.91). Conclusions Present findings showed that HIV disease burden and psychiatric characteristics might interact to impact NCI among Spanish-speaking Latinos. Considering these influences may help in the provision of comprehensive care to Spanish-speaking, Latino minority groups that suffer from NCI and HIV.

Abstract Background Human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) decreases HIV transmission. Some studies have raised concerns about a potential association between the implementation of HIV PrEP and the growing incidence rates of sexually transmitted infections (STIs) in the United States. Methods We conducted a quasi-experimental (interrupted time series) analysis of STI (syphilis, gonorrhea, and chlamydia) rates before (2000–2012) and after (2013–2017) the implementation of HIV PrEP. We also performed correlations between HIV PrEP utilization and STI cases at the national (2012–2017) and state (2017) levels. We defined HIV PrEP utilization as the number of people taking tenofovir disoproxil fumarate/emtricitabine for HIV prevention. Results HIV PrEP implementation was associated with 25% (relative risk [RR] 1.254, 95% confidence interval [CI] 1.245–1.263; P < .001) and 26% (RR 1.260, 95% CI 1.257–1.264; P < .001) increases in syphilis and gonorrhea rates, respectively, and a 12% reduction in chlamydia rates (RR: 0.884, 95% CI 0.883–0.885; P < .001). HIV PrEP utilization was correlated with the numbers of syphilis, gonorrhea, and chlamydia cases (spearman coefficients 1.00, 0.94, and 0.94, respectively; P < .001, P < .01, and P < .01, respectively). At the state level, HIV PrEP was also correlated with the number of cases of syphilis, gonorrhea, and chlamydia (spearman coefficients 0.85, 0.81, and 0.85, respectively; Ps < .001 for all correlations). Conclusions The implementation and utilization of HIV PrEP in the United States were associated with increased rates of STIs. Further studies to confirm these associations and to elucidate potential causes are needed.

Public education in the United States acts as a governmental tool of neoliberalism, through which state power and sovereignty are deployed and transformed in daily life. Here, I examine how the divergence of sovereignty is exerted over refugee students and their families in US public education. Drawing on 42 months of ethnographic data collected on refugee and other immigrant networks in Southern Arizona, a US–Mexico border region marked by increasing anti-immigrant policies and practices, I reveal how the everyday practices and policies of one school district reflect and reinforce the government’s control over refugee students. I argue that the ways in which the students are sorted, marginalized, and denied opportunities as learners is inextricable from their positioning as non-citizens by the federal and state governments. Specifically, I demonstrate the linkages between the federal education policy, Every School Succeeds Act, Arizona State’s Proposition 203: English Language Education for the Children in Public Schools, which eliminated bilingual education, and the school district’s approach to teaching refugee students. Finally, I offer recommendations for creating more inclusive, assets-based learning environments for refugee students that push back against the neoliberal favoring of competition and one-size-fits-all solutions in public education.

Hundreds of 19th-century newspapers and magazines published in the region of the US–Mexico border are housed in archival collections in Mexico and the United States, and they provide access to historical, cultural, and ideological perspectives involving two world spheres that are intimately connected. Archival collections in the following databases provide access to periodicals published in the United States as well as in Mexico: the Newspaper and Periodicals Collection at the National Autonomous University of Mexico; the Readex Collection of Hispanic American Newspapers, 1808–1980; the Nettie Lee Benson Library’s microfilmed collection of 19th-century independent newspapers; the digital collection of periodicals and magazines from the Capilla Alfonsina Biblioteca Universitaria and the Biblioteca Universitaria Raúl Rangel Frias, at the Universidad Autónoma de Nuevo León; and the EBSCO Arte Público Hispanic Historical Collections, Series 1 and 2. These collections house digitized and microfilmed newspapers that include those published in the US states of California, Arizona, Nevada, New Mexico, and Texas, as well as Mexican states such as Baja California, Sonora, Chihuahua, Coahuila, Nuevo León, and Tamaulipas. The region includes areas that share not only a physical border but also a cultural memory based on the effects of historical collisions that have contributed to the formation of new meanings regarding these world spheres that can be understood as two intersecting semiotic systems that exist as a continuum. The intersection of these spaces represents the transnational aspect of periodical print culture of the late 19th century that communicates worldviews that are semiotically and ideologically heterogeneous. Indeed, cultural spaces that exist in the borderland (or that symbolic space that forms a border or frontier in a cultural sense), are semiotic realities that unfold in unpredictable and indeterminate ways as a result of historical processes. Periodical print culture produced in the border region provides access to diverse social, cultural, political, and religious perspectives. Furthermore, the history of print culture involves a process of communication of both social and cultural history. As objects of study, borderland newspapers ultimately provide the basis for understanding the circulation of ideas.

Abstract Trimodal or bimodal age-specific incidence rates for Burkitt lymphoma (BL) were observed in the United States general population, but the role of immunosuppression could not be excluded. Incidence rates, rate ratios, and 95% confidence intervals for BL and other non-Hodgkin lymphoma (NHL), by age and CD4 lymphocyte count categories, were estimated using Poisson regression models using data from the United States HIV/AIDS Cancer Match study (1980-2005). BL incidence was 22 cases per 100 000 person-years and 586 for non-BL NHL. Adjusted BL incidence rate ratio among males was 1.6× that among females and among non-Hispanic blacks, 0.4× that among non-Hispanic whites, but unrelated to HIV-transmission category. Non-BL NHL incidence increased from childhood to adulthood; in contrast, 2 age-specific incidence peaks during the pediatric and adult/geriatric years were observed for BL. Non-BL NHL incidence rose steadily with decreasing CD4 lymphocyte counts; in contrast, BL incidence was lowest among people with ≤ 50 CD4 lymphocytes/μL versus those with ≥ 250 CD4 lymphocytes/μL (incidence rate ratio 0.3 [95% confidence interval = 0.2-0.6]). The bimodal peaks for BL, in contrast to non-BL NHL, suggest effects of noncumulative risk factors at different ages. Underascertainment or biological reasons may account for BL deficit at low CD4 lymphocyte counts.
