RESUMO
OBJECTIVE: Prior evidence demonstrates that both firearm access and fighting can predict future violence and injury in adolescents. We aimed to examine associations between firearm access with fighting behavior and conflict perception in a sample of adolescents in an urban emergency department (ED) setting. METHODS: In 2023, we conducted a secondary analysis of 13,610 adolescent encounters in the ED of a U.S. children's hospital from 2013 to 2020, using a universally applied, self-administered computerized behavioral health survey. We compared patient characteristics by reported firearm access and fighting behavior using chi-squared tests. Generalized estimating equations (GEE) were used to investigate associations between 1) fighting behavior and firearm access, and 2) between fighting behavior and respondent preference to and reporting of fighting incident to law enforcement after adjusting for race and ethnicity, age, and gender. RESULTS: Approximately one-quarter of the sample reported past year fighting. Youth who reported fighting were more likely to report firearm access (AOR = 1.66, 95%CI = [1.49-1.86]). This association strengthened among youth who perceived continued conflict after a fight (AOR = 2.05, 95%CI = [1.73-2.43]). Youth who perceived continued conflict following a fight were more likely to report (AOR = 1.97, 95%CI = [1.65-2.36]) or want to report (AOR = 2.63, 95%CI = [1.81-3.81]) the fight to law enforcement. CONCLUSIONS: Those perceiving continued conflict after a fight were more likely to report access to firearms and endorse retaliation; however, they were more likely to want to report the fight to law enforcement. These findings highlight the potential for more comprehensive ED risk assessment to reduce retaliation and reinjury for adolescents reporting fighting behavior.

Livability, or how a place and its systems (e.g., housing, transportation) supports the ability to lead a livable life, is a determinant of health. There is a lack of standard, validated measures to assess livability in the US. This study employed factor analytic methods to create measures of livability in Connecticut using data from the DataHaven Community Wellbeing Survey (DCWS) (n = 32,262). Results identified a 3-factor model (safety, opportunity, and infrastructure) as the best fit, explaining 69% of the variance in survey items. Newly created livability measures had high internal consistency, in addition to high convergent validity with other area-level measures.
RESUMO
Introduction. Immigrant nail salon owners and employees face multiple barriers to accessing occupational health training and services. We formed an academic-community-based organization-business owner partnership-unique in that all partners were culturally congruent-to develop a pilot intervention program for the nail salon community. Methods. Eighteen individuals (nine salon owners and nine employees) from the Greater Philadelphia region received the training in their native language and provided feedback through in-depth qualitative interviews. Interview guide was developed using the Consolidated Framework for Implementation Research (CFIR). Themes of perceived benefits and barriers were identified and aligned with relevant CFIR constructs to gain better understanding of the implementation challenges. Results. Reported benefits of program were improved knowledge of the workplace hazards and safety practices, and the potential to attract more customers and retain employees. Perceived barriers to implementing recommended practices were limited availability of safer products and high cost, challenges communicating with customers, lack of engagement from some owners, organizational management practices affecting employees' motivation, and limited partnership with local government to assist small immigrant-owned businesses. Conclusions. Our study revealed multiple factors that pit long-term health protection of nail salon workers against the economic viability of the businesses that employ them. Our research highlights the need to (1) advocate for federal policies making safer products to be more accessible to the masses, (2) establish local policy and culturally appropriate technical support programs that engage community-based organizations, and (3) develop economic opportunities and mentorship for immigrant entrepreneurs to operate profitable healthy salons.

Connecting evidence-based public health recommendations to livability, a popular and relatable construct, can increase the policy relevance of research to improve community design. However, there are many different definitions and conceptualizations of livability and little consensus about its measurement. Improved measurement, including standardization, is needed to increase understanding of livability's influence on health and to facilitate comparisons across contexts. This study sought to review existing livability measures, how they were created, and evidence regarding their reliability and validity. A scoping review of three databases (PubMed, Google Scholar, and Web of Science) identified 744 eligible studies. After screening, 24 studies, 15 from the original search and 9 through backward citation searches, were included in the review. Most studies were carried out in an urban context. There was minimal consensus across studies on the conceptualization of livability. However, measure domains and indicators overlapped significantly. While the process used to validate the measures varied, most studies reported high levels of reliability and found that livability was correlated with similar measures (e.g. place satisfaction, neighborhood safety, and sense of place) and self-reported health and wellbeing. Further research is needed to develop parsimonious, standardized measures of livability in order to create and sustain livable communities worldwide.
RESUMO
Predicting future evolutionary change is a critical challenge in the Anthropocene as geographic range shifts and local extinction emerge as hallmarks of planetary change. Hence, spatial sorting-a driver of rapid evolution in which dispersal-associated traits accumulate along expanding range edges and within recolonized habitats-might be of growing importance in ecology and conservation. We report on the results of a natural experiment that monitored recolonization of host plants by the seed-feeding, red-shouldered soapberry bug, Jadera haematoloma, after local extinctions from catastrophic flooding in an extreme hurricane. We tested the contribution of spatial sorting to generate rapid and persistent evolution in dispersal traits, as well as in feeding traits unrelated to dispersal. Long-winged dispersal forms accumulated in recolonized habitats and due to genetic correlation, mouthparts also became longer and this shift persisted across generations. Those longer mouthparts were probably adaptive on one host plant species but maladaptive on two others based on matching the optimum depth of seeds within their host fruits. Moreover, spatial sorting eroded recently evolved adaptive divergence in mouthpart length among all host-associated biotypes, an outcome pointing to profound practical consequences of the extreme weather event for local adaptation, population resilience and evolutionary futures.

BACKGROUND: The nail salon industry in the US comprises mostly immigrant-owned, small mom-and-pop salons that employ primarily first-generation immigrant workers from Asia. Because of the cultural and language barriers, both owners and workers may not avail themselves of the occupational safety resources. We formed an academic-community partnership to co-design a feasibility study and multi-level occupational health intervention for Vietnamese-speaking salon owners, workers, and community-based organization. METHODS: The intervention for each salon included (i) 2-h in-person training covering chemical safety, infection control, musculoskeletal prevention, and workers' rights for both the owners and their employees, (ii) a tailored recommendation report for the owner, and (iii) check-ins with the owner during the 3-month follow-up. Community partner was trained to deliver the in-language training with technical assistance from the research team. Baseline and post-intervention individual data about health symptoms and behaviors, as well as personal chemical exposures were collected and analyzed. RESULTS: A total of 44 participants from 12 consented salons enrolled in the study. One salon dropped out at follow-up due to change of ownership. Analysis of the differences between post-and pre-intervention showed a tendency toward reduction in some self-reported symptoms in the respiratory system, skin, and eyes, neurotoxicity score, as well as chemical exposures. We could not rule out seasonality as an explanation for these trends. Increase in self-efficacy in some areas was observed post-intervention. CONCLUSIONS: Our study demonstrated a successful academic-community partnership to engage community members in the intervention study. While the intervention effects from this feasibility study should be interpreted with caution, our preliminary results indicated that our community-based intervention is a promising approach to reduce work-related exposures among Asian American nail salon workers.

Latino immigrant families in the United States were disproportionately affected by intensified interior immigration enforcement under the Trump administration. US-citizen children are victimized by policies targeting their immigrant parents; research is sparse regarding how these polices affect children who experience parental deportation and children who are at risk for parental deportation. Additionally, anti-immigrant rhetoric can result in increased discrimination that also threatens children's psychological health. This qualitative study (N = 22) explores children's lived experiences of discrimination, parental deportation or threat of parental deportation, and perceived impacts on mental health. Interviews conducted from 2019 to 2020 revealed that children who are directly affected by or at risk for parental deportation experience detrimental impacts to their psychological well-being. Children experience discrimination as Latinos and children of immigrants, which is also detrimental to their mental/emotional health. Incorporating children's perspectives is critical to informing public health interventions. Findings demonstrate the need for family-friendly immigration reform.
Las familias inmigrantes latinas en los Estados Unidos se vieron desproporcionadamente afectadas por las acciones del servicio de inmigración bajo la administración de Trump. Los niños y niñas con ciudadanía estadounidense son víctimas de las políticas dirigidas a sus padres inmigrantes; las investigaciones son escasas con respecto a cómo estas políticas afectan a los menores afectados por la deportación de sus padres así como los que corren riesgo de que sus padres sean deportados. Además, la retórica antiinmigrante puede provocar un aumento en la discriminación, lo cual también representa una amenaza para la salud psicológica de estos niños y niñas. Este estudio cualitativo (N = 22) explora las experiencias de discriminación y de deportación o amenaza de deportación de los padres vividas por los menores así como los impactos percibidos en su salud mental. Las entrevistas realizadas entre 2019 y 2020 revelan que las niñas y niños directamente afectados por la deportación o el riesgo de deportación de sus padres sufren un impacto perjudicial en su bienestar psicológico. Los menores experimentan discriminación como latinos e hijos de inmigrantes, lo cual también perjudica su salud mental y emocional. Es crucial que se incorporen las perspectivas de estos menores al informar las intervenciones de salud pública. Los hallazgos demuestran la necesidad de una reforma migratoria que sea solidaria con las familias.
RESUMO
Place-based initiatives attempt to reduce persistent health inequities through multisectoral, cross-system collaborations incorporating multiple interventions targeted at varying levels from individuals to systems. Evaluations of these initiatives may be thought of as part of the community change process itself with a focus on real-time learning and accountability. We described the design, implementation, challenges, and initial results of an evaluation of the West Philly Promise Neighborhood, which is a comprehensive, child-focused place-based initiative in Philadelphia, Pennsylvania. Priorities for the evaluation were to build processes for and a culture of ongoing data collection, monitoring, and communication, with a focus on transparency, accountability, and data democratization; establish systems to collect data at multiple levels, with a focus on multiple uses of the data and future sustainability; and adhere to grant requirements on data collection and reporting. Data collection activities included the compilation of neighborhood-level indicators; the implementation of a program-tracking system; administrative data linkage; and neighborhood, school, and organizational surveys. Baseline results pointed to existing strengths in the neighborhood, such as the overwhelming majority of caregivers reporting that they read to their young children (86.9%), while other indicators showed areas of need for additional supports and were programmatic focuses for the initiative (e.g., about one-quarter of young children were not engaged in an early childhood education setting). Results were communicated in multiple formats. Challenges included aligning timelines, the measurement of relationship-building and other process-focused outcomes, data and technology limitations, and administrative and legal barriers. Evaluation approaches and funding models that acknowledge the importance of capacity-building processes and allow the development and measurement of population-level outcomes in a realistic timeframe are critical for measuring the success of place-based approaches.

The prey naivety hypothesis posits that prey are vulnerable to introduced predators because many generations in slow gradual coevolution are needed for appropriate avoidance responses to develop. It predicts that prey will be more responsive to native than introduced predators and less responsive to introduced predators that differ substantially from native predators and from those newly established. To test these predictions, we conducted a global meta-analysis of studies that measured the wariness responses of small mammals to the scent of sympatric mammalian mesopredators. We identified 26 studies that met our selection criteria. These studies comprised 134 experiments reporting on the responses of 36 small mammal species to the scent of six introduced mesopredators and 12 native mesopredators. For each introduced mesopredator, we measured their phylogenetic and functional distance to local native mesopredators and the number of years sympatric with their prey. We used predator and prey body mass as a measure of predation risk. Globally, small mammals were similarly wary of the scent of native and introduced mesopredators; phylogenetic and functional distance between introduced mesopredators and closest native mesopredators had no effect on wariness; and wariness was unrelated to the number of prey generations, or years, since first contact with introduced mesopredators. Small mammal wariness was associated with predator-prey body mass ratio, regardless of the nativity. The one thing animals do not seem to recognize is whether their predators are native.
La hipótesis de la ingenuidad de la presa plantea que ésta es vulnerable a los depredadores introducidos porque se requiere que muchas generaciones atraviesen una coevolución lenta y gradual para que se desarrollen las respuestas de evasión adecuadas. La hipótesis supone que la presa será más sensible a los depredadores introducidos que difieren notoriamente de los nativos y de aquellos recién establecidos. Realizamos un metaanálisis global de estudios que midieron las respuestas cautelosas de mamíferos pequeños ante el rastro de meso depredadores simpátricos para probar estas suposiciones. Identificamos 26 estudios que cumplieron con nuestro criterio de selección. Estos estudios estuvieron conformados por 134 experimentos que reportaban las respuestas de 36 especies de mamíferos pequeños ante el rastro de seis meso depredadores introducidos y 12 nativos. Medimos la distancia funcional y filogenética entre cada meso depredador introducido y los meso depredadores locales nativos y el número de años simpátricos con su presa. Usamos la masa corporal del depredador y la presa como medida del riesgo de depredación. A nivel mundial, los mamíferos pequeños compartieron la cautela ante el rastro de los meso depredadores nativos e introducidos; la distancia funcional y la filogenética entre los meso depredadores introducidos y el meso depredador nativo más cercano no tuvieron efecto sobre la cautela; y la cautela no estuvo relacionada con el número de generaciones de la presa, o años, desde el primer contacto con los meso depredadores introducidos. La cautela de los mamíferos pequeños estuvo asociada con las proporciones de masa corporal entre el depredador y la presa, sin importar el origen. Lo único que los animales parecen no reconocer es si el depredador es nativo o no.

OBJECTIVE: Latino populations in the United States are disproportionately affected by substance use, HIV/AIDS, violence, and mental health issues (SAVAME). A growing body of evidence demonstrates the syndemic nature of SAVAME and the need for integrated strategies to reduce their impact. This study sought to understand the network of SAVAME services for Latino immigrants in Philadelphia to inform future interventions for SAVAME prevention and mitigation. METHODOLOGY: Key informant interviews (N = 30) were conducted with providers working in Latino-serving organizations providing SAVAME services. Interviews were analyzed using thematic coding and grounded theory. RESULTS: Latino-serving providers perceived a large need for, and important limitations in the availability, accessibility, and adequacy of SAVAME services for Latino immigrants. Gaps were seen as especially acute for mental health and substance use services, partly because of insufficient funding for these services. Latino immigrants' lack of health insurance, immigration status, limited English proficiency (LEP), stigma surrounding SAVAME issues, and limited knowledge of available services were identified as significant barriers preventing access to services. Providers noted that scarcity of well-trained, culturally competent, and ethnically concordant providers reduced the adequacy of SAVAME services for Latino immigrant clients. The small size, low levels of infrastructure, and limited capacity were reported as additional factors limiting the ability of many Latino-serving organizations to adopt a syndemic approach in the prevention and treatment of SAVAME services. CONCLUSIONS: The results call for changes in the structure of funding streams and communitywide strategies to foster collaboration across SAVAME providers working with Latino immigrant clients.

Latino immigrants are disproportionately impacted by substance use, HIV/AIDS, domestic violence, and mental health (SAVAME). The burden of these syndemic conditions is influenced by limited access to health and social services to prevent and treat these conditions. The syndemic nature of these factors necessitates an integrated, coordinated approach to address them simultaneously. We analyzed characteristics of Latino-serving organizations in Philadelphia, PA, that provide SAVAME-related health and/or social services, and their interorganizational collaborations to meet the needs of Philadelphia's Latino communities. We surveyed Latino-serving organizations (N=43) identified through existing resource directories and key informants. Network analyses identified patterns and density of collaborative ties (i.e., referrals, administrative, or planning/advocacy) across organizations and characterized these ties by type of service. Density (expressed as percent of all possible ties) revealed a higher referral rate (40%) than administrative (29%) or planning (26%) coordination. Network sociograms display clusters of providers by geography. Examination of bonding (within-group) ties revealed comparable perceptions of high value among both South/Center Philadelphia (57%) and in North Philadelphia providers (56%), but bridging (between-group) ties suggest lower levels of high-value perceptions (24%). No evident clustering by type of service based on syndemic factor was observed. Density of bridging across types of providers was highest for referrals (38%) followed by planning (23%) and administrative coordination (20%). Interventions to promote collaboration between providers should focus on facilitating administrative and planning collaborations that leverage existing capacity of the network. Given the syndemic nature of these conditions, greater collaboration between providers of complementing SAVAME services is imperative.

PURPOSE OF REVIEW: The purpose of this review is to describe the role, responsibilities, hiring, training, and retention of community health workers (CHWs) on clinical care teams in the United States. RECENT FINDINGS: CHWs are unique members of clinical care teams because of their ability to foster a deep trust and understanding with patients by sharing similar life experiences, participating in home visits, and providing constant support and advocacy. By partnering with CHWs, other clinical care members also gain a better understanding of their patients allowing them to deliver more culturally competent, patient/family-centered care. CHWs when incorporated into interdisciplinary teams have shown to lower healthcare costs, reduce hospital stays and admissions, and improve health outcomes and quality of life for children and families. However, the lack of standardization among CHW programs makes it difficult to quantify the overall effect and impact of integrating CHWs into clinical care teams. SUMMARY: CHWs are able to improve health outcomes and address social determinants of health when properly integrated into clinical care teams. However, without adequate support, integration, funding, and training, CHWs are not able to reach their full potential. The standardization of CHWs' responsibilities and training, like other clinical care team members, is lacking within the United States, making it a challenge to evaluate programs and maintain sustainable funding for these vital members of the clinical care team.

Transgenic crops that produce insecticidal proteins from Bacillus thuringiensis (Bt) can suppress pests and reduce insecticide sprays, but their efficacy is reduced when pests evolve resistance. Although farmers plant refuges of non-Bt host plants to delay pest resistance, this tactic has not been sufficient against the western corn rootworm, Diabrotica virgifera virgifera In the United States, some populations of this devastating pest have rapidly evolved practical resistance to Cry3 toxins and Cry34/35Ab, the only Bt toxins in commercially available corn that kill rootworms. Here, we analyzed data from 2011 to 2016 on Bt corn fields producing Cry3Bb alone that were severely damaged by this pest in 25 crop-reporting districts of Illinois, Iowa, and Minnesota. The annual mean frequency of these problem fields was 29 fields (range 7 to 70) per million acres of Cry3Bb corn in 2011 to 2013, with a cost of $163 to $227 per damaged acre. The frequency of problem fields declined by 92% in 2014 to 2016 relative to 2011 to 2013 and was negatively associated with rotation of corn with soybean. The effectiveness of corn rotation for mitigating Bt resistance problems did not differ significantly between crop-reporting districts with versus without prevalent rotation-resistant rootworm populations. In some analyses, the frequency of problem fields was positively associated with planting of Cry3 corn and negatively associated with planting of Bt corn producing both a Cry3 toxin and Cry34/35Ab. The results highlight the central role of crop rotation for mitigating impacts of D. v. virgifera resistance to Bt corn.

Large-bodied mammalian herbivores dominated Earth's terrestrial ecosystems for several million years before undergoing substantial extinctions and declines during the Late Pleistocene (LP) due to prehistoric human impacts. The decline of large herbivores led to widespread ecological changes due to the loss of their ecological functions, as driven by their unique combinations of traits. However, recently, humans have significantly increased herbivore species richness through introductions in many parts of the world, potentially counteracting LP losses. Here, we assessed the extent to which introduced herbivore species restore lost-or contribute novel-functions relative to preextinction LP assemblages. We constructed multidimensional trait spaces using a trait database for all extant and extinct mammalian herbivores ≥10 kg known from the earliest LP (â¼130,000 ybp) to the present day. Extinction-driven contractions of LP trait space have been offset through introductions by â¼39% globally. Analysis of trait space overlap reveals that assemblages with introduced species are overall more similar to those of the LP than native-only assemblages. This is because 64% of introduced species are more similar to extinct rather than extant species within their respective continents. Many introduced herbivores restore trait combinations that have the capacity to influence ecosystem processes, such as wildfire and shrub expansion in drylands. Although introduced species have long been a source of contention, our findings indicate that they may, in part, restore ecological functions reflective of the past several million years before widespread human-driven extinctions.

Although women with intellectual disabilities have the same breast cancer incidence rate as women without intellectual disabilities, they have fewer mammograms and higher mortality rates. Qualitative inquiry was employed to explore barriers and facilitators to mammography among this population. In-depth qualitative interviews were conducted with 30 women with intellectual disabilities and their caregivers in Philadelphia during 2015-2016. Thematic analysis was conducted using inductive and deductive coding. While results provide further evidence for prior research on barriers to mammography among women with intellectual disabilities (e.g. being unprepared, fear of the exam), this study generated novel barriers such as lack of breast ultrasound awareness, sedation failing to work, and lack of mammogram education in adult day programs, and novel facilitators such as extended family support and positive attitudes. Results support the need to address barriers and promote facilitators to improve the breast cancer screening experience among women with intellectual disabilities.
RESUMO
Conservation science involves the collection and analysis of data. These scientific practices emerge from values that shape who and what is counted. Currently, conservation data are filtered through a value system that considers native life the only appropriate subject of conservation concern. We examined how trends in species richness, distribution, and threats change when all wildlife count by adding so-called non-native and feral populations to the International Union for Conservation of Nature Red List and local species richness assessments. We focused on vertebrate populations with founding members taken into and out of Australia by humans (i.e., migrants). We identified 87 immigrant and 47 emigrant vertebrate species. Formal conservation accounts underestimated global ranges by an average of 30% for immigrants and 7% for emigrants; immigrations surpassed extinctions in Australia by 52 species; migrants were disproportionately threatened (33% of immigrants and 29% of emigrants were threatened or decreasing in their native ranges); and incorporating migrant populations into risk assessments reduced global threat statuses for 15 of 18 species. Australian policies defined most immigrants as pests (76%), and conservation was the most commonly stated motivation for targeting these species in killing programs (37% of immigrants). Inclusive biodiversity data open space for dialogue on the ethical and empirical assumptions underlying conservation science.
Cuando Toda la Vida Importa en la Conservación Resumen La ciencia de la conservación involucra la recolección y el análisis de datos. Estas prácticas científicas emergen de los valores que forman quién y qué se cuenta. Actualmente, los datos de conservación son filtrados a través de un sistema de valores que considera a la vida nativa como el único sujeto apropiado para el interés de la conservación. Examinamos cómo cambian las tendencias de riqueza de especies, distribución y amenazas cuando se considera a toda la vida silvestre con la adición de las poblaciones denominadas como no nativas y ferales a la Lista Roja de la Unión Internacional para la Conservación de la Naturaleza y a las evaluaciones de riqueza local de especies. Nos enfocamos en las poblaciones de vertebrados que cuentan con miembros fundadores llevados y extraídos de Australia (es decir, migrantes). Identificamos 87 especies inmigrantes de vertebrados y 47 especies emigrantes. Los informes formales de conservación subestimaron los rangos globales por un promedio del 30% para las especies inmigrantes y del 7% para las especies emigrantes; las inmigraciones rebasaron las extinciones en Australia por 52 especies; las especies migrantes estuvieron amenazadas de manera desproporcionada (33% de las especies inmigrantes y 29% de las especies emigrantes estaban amenazadas o declinando en sus distribuciones nativas); y la incorporación de las poblaciones migrantes a las evaluaciones de riesgo redujeron el estado mundial de amenaza para 15 de las 18 especies. Las políticas australianas definen a la mayoría de las especies inmigrantes como plagas (76%) y se citó a la conservación como la principal motivación para enfocarse en estas especies durante los programas de erradicación (37% de las especies inmigrantes). La información inclusiva de conservación genera un espacio para el diálogo sobre las suposiciones éticas y empíricas subyacentes en la ciencia de la conservación.

Cooperative management of pest susceptibility to transgenic Bacillus thuringiensis (Bt) crops is pursued worldwide in a variety of forms and to varying degrees of success depending on context. We examine this context using a comparative socioecological analysis of resistance management in Australia, Brazil, India, and the United States. We find that a shared understanding of resistance risks among government regulators, growers, and other actors is critical for effective governance. Furthermore, monitoring of grower compliance with resistance management requirements, surveillance of resistance, and mechanisms to support rapid implementation of remedial actions are essential to achieve desirable outcomes. Mandated resistance management measures, strong coordination between actors, and direct linkages between the group that appraises resistance risks and growers also appear to enhance prospects for effective governance. Our analysis highlights factors that could improve current governance systems and inform other initiatives to conserve susceptibility as a contribution to the cause of public good.

The use of skin-applied repellents is the primary method recommended by the Centers for Disease Control and Prevention for personal protection against biting mosquitoes. Historically, the majority of long-efficacy mosquito repellents have been N,N diethyl-3-methylbenzamide (deet)-based. Recently, a variety of new botanical formulations have been marketed, but their protection times generally continue to fall well short of high-concentration deet products. We present a laboratory arm-in-cage study of a Neo-Innova® repellent that has a prolonged action "NEO-PART®" (Prolonged Action Release Technology) formulation with 40% Citriodiol®. This formulation provides the botanical molecule para-menthane 3,8-diol (PMD) at 25% w/v of the total formulation. Against Aedes aegypti, Neo-Innova's mean complete protection time (CPT; 14.2 h) was approximately 2 to 3 times longer than that of 5 leading high-performance repellents marketed in the USA, including 25% deet and a 20% PMD ethanolic formulation. When testing Neo-Innova, 5 of the 6 subjects had no landings after 15 h. The 6th had single landings at 10 and 11 h (individual CPT of 10 h), but received no additional landings in further exposures made at 13 and 15 h. Neo-Innova repellency against Culex quinquefasciatus was similarly prolonged. The tremendous increment in repellency duration observed for the Neo-Innova product, when compared with both current standard and botanical repellent options, represents a milestone in repellent development and supports "once-a-day" applications as a practical strategy for personal protection against mosquitoes.

Little information exists on the associations between intellectual disability (ID) and race/ethnicity on mammogram frequency. This study collected survey and medical record data to examine this relationship. Results indicated that Hispanic and Black women with ID were more likely than White women with ID to have mammograms every 2 years. Participants who live in a state-funded residence, were aged 50+, and had a mild or moderate level of ID impairment were more likely to undergo mammography compared to participants living with family or alone, were <50, and had severe ID impairment. Further research is needed to understand the mechanisms explaining disparities in mammograms between these racial/ethnic groups.
