Development, Implementation, and Evaluation of Three Outreach Events to Improve COVID-19 Vaccine Uptake Among Racial and Ethnic Minority Communities in Houston, Texas, 2022.

OBJECTIVES: Lack of access to timely, accurate, and linguistically appropriate COVID-19 information has complicated the dissemination of evidence-based information and contributed to vaccine hesitancy among racial and ethnic minority groups in the United States. We developed community events that provided outreach, education, and access to COVID-19 vaccination to overcome vaccine hesitancy in these communities. METHODS: Using spatial analysis techniques, we identified 3 communities with low vaccine uptake in Houston, Texas, in fall 2021; engaged 20 stakeholders from these communities via 4 focus groups to understand barriers to vaccination; and developed and implemented 3 COVID-19 vaccine education and outreach events tailored to the needs of these communities in January-March 2022. We used program evaluation surveys to assess attendee characteristics and satisfaction with the events. Vaccinated attendees also completed surveys on what motivated them to get vaccinated. RESULTS: Two communities were predominantly Hispanic, and the third had an equal number of Black and Hispanic residents. Based on community stakeholder input, the study team organized 2 health fairs and 1 community festival featuring dialogue-based COVID-19 vaccine engagement in January and March 2022. Across the 3 events, a total of 865 attendees received COVID-19 education and 205 (24.0%) attendees received a COVID-19 vaccine or booster. Of 90 attendees who completed program evaluation surveys, 81 (90%) rated the outreach event as good or excellent. Of 145 attendees who completed postvaccination surveys, 132 (91%) endorsed ≥1 key program feature as motivating them to either get vaccinated or vaccinate their child that day. CONCLUSION: Community outreach events are important strategies for disseminating information, building trust, and facilitating COVID-19 vaccine uptake.

An overview of GeoAI applications in health and healthcare.

The moulding together of artificial intelligence (AI) and the geographic/geographic information systems (GIS) dimension creates GeoAI. There is an emerging role for GeoAI in health and healthcare, as location is an integral part of both population and individual health. This article provides an overview of GeoAI technologies (methods, tools and software), and their current and potential applications in several disciplines within public health, precision medicine, and Internet of Things-powered smart healthy cities. The potential challenges currently facing GeoAI research and applications in health and healthcare are also briefly discussed.

Health risks from lost awareness of cultural behaviours rooted in traditional medicine: An insight in geophagy and mineral intake.

The term geophagy is applied to the recurrent intentional eating of soil with multifactorial motivation. Geophagists are generally defined by gender (women), age (children), physical status (e.g. pregnancy, lactation, postpartum), social status (people exposed to significant nutritional deficiencies), and culture, but lost awareness of traditional medical meaning of this practice is changing these consumption patterns and increasing health risks. Moreover, although the holistic anthropological perspective recognizes soil consumption as mineral supplementation under certain circumstances, we should consider how the living environment has changed and is changing, along with diet, nutrition requirements, and habits. Therefore, benefits-to-risks ratio of cultural behaviours initiated centuries ago based on traditional medical practices requires deep revision and assessment. Knowledge on minerals metabolism, bioavailability and interactions is required to properly assess the role of geophagy in a balanced and safe intake of micronutrients. Most important, the risk of unbalanced intake of minerals may be serious since the mineralogy and chemistry of geophagic clays are uncontrolled, variable, and difficult to standardize. In addition, other factors (radioactive materials, organic chemicals and soil pathogens) complicate the risk assessment for population groups consuming soil. Since the geophagic practice is expected to persist despite economic development, the paper discusses the multifaceted spectrum of geophagy to highlight critical aspects for risk management.

Waterborne toxoplasmosis investigated and analysed under hydrogeological assessment: new data and perspectives for further research

We present a set of data on human and chicken Toxoplasma gondiiseroprevalence that was investigated and analysed in light of groundwater vulnerability information in an area endemic for waterborne toxoplasmosis in Brazil. Hydrogeological assessment was undertaken to select sites for water collection from wells for T. gondiioocyst testing and for collecting blood from free-range chickens and humans for anti-T. gondiiserologic testing. Serologic testing of human specimens was done using conventional commercial tests and a sporozoite-specific embryogenesis-related protein (TgERP), which is able to differentiate whether infection resulted from tissue cysts or oocysts. Water specimens were negative for the presence of viable T. gondiioocysts. However, seroprevalence in free-range chickens was significantly associated with vulnerability of groundwater to surface contamination (p < 0.0001; odds ratio: 4.73, 95% confidence interval: 2.18-10.2). Surprisingly, a high prevalence of antibodies against TgERP was detected in human specimens, suggesting the possibility of a continuous contamination of drinking water with T. gondiioocysts in this endemic setting. These findings and the new proposed approach to investigate and analyse endemic toxoplasmosis in light of groundwater vulnerability information associated with prevalence in humans estimated by oocyst antigens recognition have implications for the potential role of hydrogeological assessment in researching waterborne toxoplasmosis at a global scale.
