Due to stigma or legal issues, populations with higher HIV risk are often hard to reach, which impedes accurate population estimation of HIV burden. To better sample hard-to-reach populations (HTRPs) for HIV surveillance, various sampling methods have been designed and/or used since HIV epidemic following the first reported AIDS cases in 1981. ⋯ However, current evidence is still inadequate for RDS to be considered the best option for sampling HTRPs. The field must continue to assess RDS and to develop new sampling approaches or modifications to existing approaches.

Exposure to violence is a critical aspect of contemporary racial inequality in the United States. While extensive research has examined variations in violent crime rates across neighborhoods, less attention has been given to understanding individuals' everyday exposure to violent crimes. This study investigates patterns of exposure to violent crimes among neighborhood residents using cell phone mobility data and violent crime reports from Chicago. ⋯ Additionally, the analysis suggests that neighborhoods with more Hispanic and Asian residents are exposed to less and more violent crime, respectively, compared to neighborhoods with more White residents. However, this is only observed when not adjusting for the volume of visits points of interest receive; otherwise, the finding is reversed. This study offers valuable insights into potentially novel sources of racial disparities in exposure to violent crimes in everyday contexts, highlighting the need for further investigation.

Nine in 10 road traffic deaths occur in low- and middle-income countries (LMICs). Despite this disproportionate burden, few studies have examined built environment correlates of road traffic injury in these settings, including in Latin America. We examined road traffic collisions in Bogotá, Colombia, occurring between 2015 and 2019, and assessed the association between neighborhood-level built environment features and pedestrian injury and death. ⋯ Neighborhoods with more street trees (RR, 0.90; 95% CI, 0.82-0.98), traffic signals (0.89, 0.81-0.99), and bus stops (0.89, 0.82-0.97) were associated with lower pedestrian road traffic deaths. Neighborhoods with greater density of large roads were associated with higher pedestrian injury. Our findings highlight the potential for pedestrian-friendly infrastructure to promote safer interactions between pedestrians and motorists in Bogotá and in similar urban contexts globally.

Randomized Controlled Trial
Actual and Virtual Parks Benefit Quality of Life and Physical Activity: A Cluster Trial.
Urban parks provide connectedness to nature as a health resilience environment for promoting health. Virtual reality can provide opportunities for urban citizens to be exposed to natural elements with health benefits. The purpose was to explore the effects of actual and virtual parks on the quality of life and physical activity of urban residents. ⋯ Participants in the experimental groups of both kinds of parks had significant improvements in their self-rated health, physical and environmental quality of life, and sedentary time after the intervention. Urban parks are an important natural resource for citizens' health and physical activity promotion. Virtual parks can simulate actual parks and have similar health benefits and are thus are recommended for citizens who lack opportunities and motivation to go to actual parks.

Few studies have investigated plants' healing effects, particularly through touch-based therapy, on older adults. As hypertension rates continue to climb worldwide, touch-based therapy for hypertension prevention has become a significant priority in public health initiatives. This study investigated the impact of tactile interaction with real grass (a landscape activity) versus artificial grass on older adults' physical and cognitive abilities. ⋯ Furthermore, the participants' brainwave patterns-measured in mean power units-exhibited an upward trend while interacting with real grass, whereas they exhibited a downward trend during the interaction with artificial grass. Moreover, the mean systolic blood pressure significantly decreased following interaction with real grass. These findings suggest that engaging with real grass through touch potentially alleviates mental stress, in contrast to the effects of artificial grass.
