Empowerment through knowledge: Qualitative perceptions of 'undetectable equals Untransmittable' among people living with HIV and tuberculosis in South Africa.

Introduction: Undetectable equals untransmittable (U=U) is an education campaign promoting science that people living with human immunodeficiency virus (HIV) who maintain an undetectable viral load cannot transmit HIV to others. Researchers theorize that undetectable equals untransmittable messaging will decrease HIV stigma by reducing fears of HIV transmission and providing evidence to dismantle discriminatory policies. However, little is known about how people with HIV in South Africa interpret the results of their viral load tests, undetectable equals untransmittable messaging, or its impact on stigma.

Background: Advanced age brings a loss of plantar sensation, represented, for example, as higher sensation thresholds in standardized testing. This is thought to contribute to an increased risk of falls among older adults - an intuitive premise that has yet to be fully investigated, especially in the context of walking balance. The purpose of this study was to quantify the association between plantar sensation and the instability elicited by a suite of walking balance perturbations that differ in direction and context in a cohort of n = 28 older adults (73.

Climate change poses an unprecedented threat to human health and well-being in the United States. In this article, part of the National Academy of Medicine's Vital Directions for Health and Health Care: Priorities for 2025 initiative, we outline key strategies to address climate change, health, and equity, using a public health approach. We focus on three critical areas: transitioning to clean energy sources, upgrading health infrastructure, and scaling public health and health care resilience.

Nanostructured dielectric metasurfaces offer unprecedented opportunities to control light-matter momentum exchange, and thereby the forces and torques that light can exert on matter. Here we introduce optical metasurfaces as components of ultracompact untethered microscopic metaspinners capable of efficient light-induced rotation in a liquid environment. Illuminated by weakly focused light, a metaspinner generates torque via photon recoil through the metasurfaces' ability to bend light towards high angles despite their sub-wavelength thickness, thereby creating orbital angular momentum.

Objective: The adoption of policies promoting healthier restaurant food environments is contingent on their acceptability. Limited evidence exists regarding individual characteristics associated with restaurant food environment policy acceptability, especially health-related characteristics. This study examined associations between health characteristics and restaurant food environment policy acceptability among urban Canadians.
