Risk Factors for HIV Transmission Among Hispanic Men Who Have Sex With Men in Atlanta
This study assessed and compared demographic factors, psychosocial factors, health seeking behavior, and sexual practices of two convenience samples of Hispanic/Latino gay men and men who have sex with men (MSM) in the metropolitan Atlanta region. The aim was to obtain data on emerging HIV/AIDS patterns in this group. Bilingual surveys were conducted in 2000 and 2006 at local gay bars. Discrepancies observed between HIV/AIDS knowledge and sexual behaviors in 2000 were replicated in 2006. Contrary to expected improvements due to enhanced HIV/AIDS education and awareness, risk behavior for HIV/STDs increased significantly between 2000 and 2006. These findings should inform the design and delivery of programs aimed at meeting the HIV/AIDS prevention, education and treatment needs of this growing population
Smoke, curtains and mirrors: the production of race through time and title registration
This article analyses the temporal effects of title registration and their relationship to race. It traces the move away from the retrospection of pre-registry common law conveyancing and toward the dynamic, future-oriented Torrens title registration system. The Torrens system, developed in early colonial Australia, enabled the production of ‘clean’, fresh titles that were independent of their predecessors. Through a process praised by legal commentators for ‘curing’ titles of their pasts, this system produces indefeasible titles behind its distinctive ‘curtain’ and ‘mirror’, which function similarly to magicians’ smoke and mirrors by blocking particular realities from view. In the case of title registries, those realities are particular histories of and relationships with land, which will not be protected by property law and are thus made precarious. Building on interdisciplinary work which theorises time as a social tool, I argue that Torrens title registration produces a temporal order which enables land market coordination by rendering some relationships with land temporary and making others indefeasible. This ordering of relationships with land in turn has consequences for the human subjects who have those relationships, cutting futures short for some and guaranteeing permanence to others. Engaging with Renisa Mawani and other critical race theorists, I argue that the categories produced by Torrens title registration systems materialise as race
Stakeholders' perspectives on health workforce policy reform
We administered an electronic survey in October-November 2006 to gauge stakeholder perspectives on Australia's recently adopted health workforce policies. Nearly all of the 41 survey respondents (65% response rate) ranked workforce as very important to overall health policy. Respondents identified decreasing health disparities and rates of disease and mortality as top goals, and identified improved quality and safety and more professionals in rural areas as priority measures for success. Lack of coordination between the governments and insufficient long-range planning were seen as threats to the success of the new workforce initiatives. The survey results suggest the need for clear goals and measurable outcomes. Although they represented different organisations and perspectives, the health workforce policy opinion leaders that participated in this survey reflected remarkable commonality in goals, measures, alternatives, and potential threats
TRENDS IN ABDOMINAL OBESITY IN YOUNG PEOPLE: UNITED STATES 1988–2002
Objective: To determine the prevalence and trends of abdominal obesity from 1988–1994 to 1999–2002 in American White, Black, and Hispanic youths. Methods: Data (N55020) from the 1988– 1994 and 1999–2002 US National Health and Nutrition Examination Surveys were used for this analysis. Abdominal obesity was defined as sex-specific values $95th percentile for waist circumference. Prevalence of abdominal obesity was compared across study periods, race/ ethnicity, socioeconomic status (SES), and age groups 6–11 years. Results: Between 1988–1994 and 1999– 2002, increases in waist circumference exceeded those of body mass index in White, Black, and Hispanic young people. The prevalence of abdominal obesity was higher in the 1999–2002 than the 1988–1994 study periods. In 1988 1994, prevalences of abdominal obesity in White, Black, and Hispanic boys were 3.0%, 3.2%, and 6.2% compared with 5.6%, 5.0%, and 9.1% in 1999–2002. The values in girls were 3.9%, 2.9%, and 4.9% in 1988–1994 and 6.0%, 8.1%, and 8.5% in 1999–2002, respectively. Prevalences of abdominal obesity increased with decreasing level of SES in 1988–1994 and 1999–2002 for Whites, Blacks, and Hispanics. At same levels of SES, prevalences of abdominal obesity were higher in Blacks and Hispanic children compared to White children. Conclusion: The trend toward increasing obesity among White, Black, and Hispanic American youths is compounded by an unequal increase in abdominal fat accumulation. Further studies are needed to determine the long-term significance of these trends, particularly in Hispanic youths who have greater tendencies for abdominal obesity compared with White and Black youths. The higher increase in the anthropometric markers (waist circumference) of abdominal obesity compared to body mass index suggests that body mass index may be inadequate in estimating changes in generalized adiposity in young people. Health promotion programs in the United States including education, nutrition, and appropriate physical activity targeted at children may help to ameliorate obesity epidemics. Emphasis should be placed on reducing abdominal obesity through physical activity and nutrition, both in school and at home for all children

Risk of COVID-19 after natural infection or vaccinationResearch in context
Background: While vaccines have established utility against COVID-19, phase 3 efficacy studies have generally not comprehensively evaluated protection provided by previous infection or hybrid immunity (previous infection plus vaccination). Individual patient data from US government-supported harmonized vaccine trials provide an unprecedented sample population to address this issue. We characterized the protective efficacy of previous SARS-CoV-2 infection and hybrid immunity against COVID-19 early in the pandemic over three-to six-month follow-up and compared with vaccine-associated protection. Methods: In this post-hoc cross-protocol analysis of the Moderna, AstraZeneca, Janssen, and Novavax COVID-19 vaccine clinical trials, we allocated participants into four groups based on previous-infection status at enrolment and treatment: no previous infection/placebo; previous infection/placebo; no previous infection/vaccine; and previous infection/vaccine. The main outcome was RT-PCR-confirmed COVID-19 >7–15 days (per original protocols) after final study injection. We calculated crude and adjusted efficacy measures. Findings: Previous infection/placebo participants had a 92% decreased risk of future COVID-19 compared to no previous infection/placebo participants (overall hazard ratio [HR] ratio: 0.08; 95% CI: 0.05–0.13). Among single-dose Janssen participants, hybrid immunity conferred greater protection than vaccine alone (HR: 0.03; 95% CI: 0.01–0.10). Too few infections were observed to draw statistical inferences comparing hybrid immunity to vaccine alone for other trials. Vaccination, previous infection, and hybrid immunity all provided near-complete protection against severe disease. Interpretation: Previous infection, any hybrid immunity, and two-dose vaccination all provided substantial protection against symptomatic and severe COVID-19 through the early Delta period. Thus, as a surrogate for natural infection, vaccination remains the safest approach to protection. Funding: National Institutes of Health
