Integrating community perceptions into One Health assessments is critical to understanding the structural barriers that create disproportionate health outcomes for community members, their pets, and the ecosystems that encompass them, particularly in historically marginalized and under-resourced communities. The validated One Health Community Assessment (OHCA) survey instrument was used to evaluate the associated impacts of The Humane Society of the United States' Pets for Life (PFL) programming on communities' perceptions of One Health. This evaluation took place across two phases, totaling four years. In phase one (May 2018 - December 2019), the PFL intervention was administered to one urban and one rural under-resourced community, while two demographically-paired communities served as comparison sites. Five OHCA subscales (human health, pet health, environmental health, community health, perceived links) were employed to measure changes in perceptions of One Health and fourteen OHCA items were used to measure perceptions of access to human healthcare, pet care, and the environment. Initiation of the confirmatory second phase of the study (May 2020-October 2021), in which all four communities received the intervention, coincided with the onset of the COVID-19 pandemic. The pandemic and its resulting public health mandates hindered both PFL programming and data collection. Generalized Estimating Equations were employed in both the first and second phase analyses to model changes in perceptions of One Health associated with the PFL intervention. In the study's first phase, PFL in the urban community was associated with significant increases in perceptions of community health and environmental health, and perceived access to human health care, pet care, and the environment. The presence of PFL during the study's second phase was associated with increased perceptions of environmental health. The variables of PFL and the pandemic were not able to be isolated within the analyses. However, due to the severe, negative One Health implications associated with the COVID-19 pandemic, the phase two results were interpreted from the perspective of the pandemic being the largest driver of the results. The results are consistent with previous research on the effects of the pandemic on community perceptions of health. These findings offer initial support for the hypothesis that deployment of resources focused on companion animals may affect perceptions across the One Health triad and confirms previous research on effects of the COVID-19 pandemic., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Hawes, O’Reilly, Mascitelli, Winczewski, Dazzio, Arrington and Morris.)

A 3D-printing approach is used to fabricate green bodies/precursor microarchitectures that, upon annealing, allow the fabrication of hierarchical 3D hollow microarchitectures (3DHMs). The 3DHMs are composed mainly of TiO 2 and inorganic stabilizers that enable the production of inorganic cellular units upon thermal annealing at 650 °C. Morphological inspection reveals that the 3D architecture beams comprise TiO 2 nanoparticles (NPs). The inner and outer diameters of the hollow beams are ∼80 μm and ∼150 μm, retained throughout the 3D hollow network. A proof-of-concept photo-Fenton reaction is assessed. The 3DHMs are impregnated with α-Fe 2 O 3 NPs to evaluate solar photo-Fenton degradation of organic compounds, such as MB used as control and acetaminophen, an organic pollutant. The optical, structural, and chemical environment characteristics, alongside scavenger analysis, generate insights into the proposed solar photo-Fenton degradation reaction over TiO 2 3DHMs loaded with α-Fe 2 O 3 . Our work demonstrates newly hollow printed microarchitecture with interconnected networks, which can help direct catalytic reactions., Competing Interests: There are no conflicts to declare., (This journal is © The Royal Society of Chemistry.)

Microscale functional materials permit advanced applications in optics and photonics. This work presents the additive manufacturing of three-dimensional structured phosphors emitting red, green, blue, and white. The development is a step forward to realizing additive colour synthesis within complex architectures of relevance in integrated optics or light-emitting sources.

Understanding social, economic, and structural barriers to accessing pet care services is important for improving the health and welfare of companion animals in underserved communities in the U.S. From May 2018-December 2019, six questions from the validated One Health Community Assessment were used to measure perceptions of access to pet care in two urban and two rural zip codes. One urban and one rural community received services from a pet support outreach program (Pets for Life), while the other served as a comparison community. After propensity score matching was performed to eliminate demographic bias in the sample (Urban = 512 participants, Rural = 234 participants), Generalized Estimating Equations were employed to compare the six measures of access to pet care between the intervention and comparison communities. The urban community with the Pets for Life intervention was associated with a higher overall measure of access to pet care compared to the urban site that did not have the Pets for Life intervention. When assessing each of the six measures of access to care, the urban community with the Pets for Life intervention was associated with higher access to affordable pet care options and higher access to pet care service providers who offer payment options than the community without the Pets for Life intervention. Further analyses with a subset of Pets for Life clients comparing pre-intervention and post-intervention survey responses revealed statistically significant positive trends in perceptions of two of the six measures of access to pet care. This study provides evidence that community-based animal welfare programming has the potential to increase perceptions of access to pet support services., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Hawes, Hupe, Winczewski, Elting, Arrington, Newbury and Morris.)
