Informing Policy on Built Environments to Safeguard Children in Environmental Justice Communities: Case Study of Five AAP Climate Advocates

Climate change’s health effects are most strongly felt in Environmental Justice (EJ) communities which are predominantly people of color. This results in a disproportionate burden of climate change health effects on EJ communities. Climate change is a public health crisis, and more importantly to pediatricians – it is a pediatric public health crisis. We are five pediatricians who are part of the American Academy of Pediatrics (AAP) Climate Advocate Program representing four diverse regions; Colorado, California, Puerto Rico, and North Carolina. We are applied research practitioners, as we live in the world between academic research and clinical practice. We are natural advocates to ensure that the future world is rebuilt with children’s health, especially children of EJ communities, at the center. Each of us has seen the direct effects of climate change adversely impact EJ Communities. In this article, we will briefly review the literature on the dangers that children face in the air they breathe, the lack of natural green spaces, and the increasingly hostile built environments, especially to children in EJ communities. We will review opportunities in our local areas to change the built environment that will work toward reducing carbon emissions and increase overall pediatric health. We will illustrate the commonalities that helped us succeed as Climate Advocates including collaboration, working locally, and purposefully choosing to identify ourselves as climate advocates and child-advocates. The intersection between public health, policy, and medicine will now become increasingly important as we head into this new decade and approach the point of no return on climate change

Impact of the government's restrictions and guidance in relation to “social distancing” on the lives of ethnic minority populations:A mixed methods study

Background and Aims: The impacts of the COVID-19 pandemic have not been equal, with a disproportionate impact among ethnic minority communities. Structural inequalities in social determinants of health such as housing and employment have contributed to COVID-19's impact on deprived communities, including many ethnic minority communities. To compare (1) how the UK government's “social distancing” restrictions and guidance were perceived and implemented by ethnic minority populations compared to white populations, (2) the impact of restrictions and guidance upon these groups. Methods: An explanatory sequential mixed methods study incorporated a quantitative survey and qualitative semi-structured interviews to explore individual perceptions and experiences of COVID-19 and the national restrictions. Survey participants (n = 1587) were recruited from North West England; 60 (4%) participants were from ethnic minority communities. Forty-nine interviews were conducted; 19 (39%) participants were from ethnic minority communities. Interviews were transcribed verbatim and analysed using a thematic approach. Data collection was between April and August 2020. Results: Significant differences in demographics and household overcrowding were observed between white vs ethnic minority survey respondents, who were also significantly less confident in their knowledge of COVID-19, less likely to be high-risk drinkers, and marginally more likely to have experienced job loss and/or reduced household income. There were no group differences in wellbeing, perceptions, or nonfinancial impacts. Two inter-related themes included: (1) government guidance, incorporating people's knowledge and understanding of the guidance and their confusion/frustration over messaging; (2) the impacts of restrictions on keyworkers, home-schooling, working from home and changes in lifestyle/wellbeing. Conclusions: Further research is needed on the long-term impacts of COVID-19 on ethnic minority communities. If policy responses to COVID-19 are to benefit ethnic minority communities, there is a need for future studies to consider fundamental societal issues, such as the role of housing and economic disadvantage.</p

Hydration dynamics at fluorinated protein surfaces

Water-protein interactions dictate many processes crucial to protein function including folding, dynamics, interactions with other biomolecules, and enzymatic catalysis. Here we examine the effect of surface fluorination on water-protein interactions. Modification of designed coiled-coil proteins by incorporation of 5,5,5-trifluoroleucine or (4S)-2-amino-4-methylhexanoic acid enables systematic examination of the effects of side-chain volume and fluorination on solvation dynamics. Using ultrafast fluorescence spectroscopy, we find that fluorinated side chains exert electrostatic drag on neighboring water molecules, slowing water motion at the protein surface

Retracing Micro-Epidemics of Chagas Disease Using Epicenter Regression

Vector-borne transmission of Chagas disease has become an urban problem in the city of Arequipa, Peru, yet the debilitating symptoms that can occur in the chronic stage of the disease are rarely seen in hospitals in the city. The lack of obvious clinical disease in Arequipa has led to speculation that the local strain of the etiologic agent, Trypanosoma cruzi, has low chronic pathogenicity. The long asymptomatic period of Chagas disease leads us to an alternative hypothesis for the absence of clinical cases in Arequipa: transmission in the city may be so recent that most infected individuals have yet to progress to late stage disease. Here we describe a new method, epicenter regression, that allows us to infer the spatial and temporal history of disease transmission from a snapshot of a population\u27s infection status. We show that in a community of Arequipa, transmission of T. cruzi by the insect vector Triatoma infestans occurred as a series of focal micro-epidemics, the oldest of which began only around 20 years ago. These micro-epidemics infected nearly 5% of the community before transmission of the parasite was disrupted through insecticide application in 2004. Most extant human infections in our study community arose over a brief period of time immediately prior to vector control. According to our findings, the symptoms of chronic Chagas disease are expected to be absent, even if the strain is pathogenic in the chronic phase of disease, given the long asymptomatic period of the disease and short history of intense transmission

Consumo de comida ultraprocesada y nivel socioeconómico : un análisis transversal del Estudio Longitudinal Brasileño sobre Salud en la Edad Adulta (ELSA-Brasil)

The objective of the study was to estimate the contribution of ultra-processed foods to total caloric intake and investigate whether it differs according to socioeconomic position. We analyzed baseline data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil 2008-2010; N = 14.378) and data on dietary intake using a food frequency questionnaire, assigning it into three categories: unprocessed or minimally processed foods and processed culinary ingredients, processed foods, and ultra-processed foods. We measured the associations between socioeconomic position (education, per capita household income, and occupational social class) and the percentage of caloric contribution of ultra-processed foods, using generalized linear regression models adjusted for age and sex. Unprocessed or minimally processed foods and processed culinary ingredients contributed to 65.7% of the total caloric intake, followed by ultra-processed foods (22.7%). After adjustments, the percentage of caloric contribution of ultra-processed foods was 20% lower among participants with incomplete elementary school when compared to postgraduates. Compared to individuals from upper income classes, the caloric contribution of ultra-processed foods was 10%, 15% and 20% lower among the ones from the three lowest income, respectively. The caloric contribution of ultra-processed foods was also 7%, 12%, 12%, and 17% lower among participants in the lowest occupational social class compared to those from high social classes. Results suggest that the caloric contribution of ultra-processed foods is higher among individuals from high socioeconomic positions with a dose-response relationship for the associations.O estudo teve como objetivo estimar a contribuição dos alimentos ultraprocessados à ingestão calórica total e investigar se essa contribuição difere de acordo com nível socioeconômico. Analisamos os dados da linha de base do Estudo Longitudinal de Saúde do Adulto-Brasil (ELSA-Brasil 2008-2010; N = 14.378) e os de ingestão alimentar, usando um questionário sobre frequência de consumo alimentar, em três categorias: alimentos não processados ou minimamente processados e ingredientes culinários processados, alimentos processados e alimentos ultraprocessados. Estimamos as associações entre nível socioeconômico (escolaridade, renda domiciliar per capita e classe social ocupacional) e o percentual da contribuição calórica dos ultraprocessados, usando modelos lineares generalizados, ajustados por idade e sexo. Os alimentos não processados ou minimamente processados e ingredientes culinários processados representaram 65,7% da ingestão calórica total, seguidos pelos ultraprocessados (22,7%). Depois dos ajustes, a contribuição dos ultraprocessados foi 20% mais baixa entre participantes com ensino fundamental incompleto, quando comparados aos indivíduos com pós-graduação. Quando comparados aos indivíduos das classes de renda mais alta, a contribuição calórica dos ultraprocessados foi 10%, 15% e 20% mais baixa entre aqueles pertencentes aos três quintis de renda mais baixos, respectivamente. Além disso, a contribuição calórica dos ultraprocessados foi 7%, 12%, 12% e 17% mais baixa entre os participantes da classe social ocupacional mais baixa, comparados aos das classes sociais mais altas. Os resultados sugerem que a contribuição calórica dos alimentos ultraprocessados é mais alta entre os indivíduos de nível socioeconômico mais alto, com gradiente de dose e resposta nas associações.El objetivo del estudio fue estimar la contribución de las comidas ultraprocesadas en la ingesta total calórica e investigar si difiere según el nivel socioeconómico. Analizamos datos de referencia, procedentes del Estudio Longitudinal Brasileño sobre Salud en la Edad Adulta (ELSA-Brasil 2008-2010; N = 14.378) y datos de la ingesta nutricional, usando un cuestionario de frecuencia sobre comidas, asignándole tres categorías: comida sin procesar o mínimamente procesada e ingredientes culinarios procesados, comidas procesadas, y comidas ultraprocesadas. Medimos las asociaciones entre el nivel socioeconómico (educación, ingreso por hogar per cápita, y clase ocupacional social) y el porcentaje de la contribución calórica de la comida ultraprocesada, usando modelos de regresión lineal generalizada, ajustados por edad y sexo. Las comidas sin procesar o mínimamente procesadas con ingredientes culinarios procesados contribuyeron al 65,7% del total de la ingesta calórica, seguidos de la comida ultraprocesada (22,7%). Tras los ajustes, el porcentaje de la contribución calórica de la comida ultraprocesada fue un 20% menor entre los participantes con la escuela elemental incompleta, cuando se compararon con los postgraduados. Comparados con los individuos de las clases con ingresos superiores, la contribución calórica de las comidas ultraprocesadas fue un 10%, 15% y 20% menor entre quienes pertenecían a las tres categorías de ingresos más bajas, respectivamente. La contribución calórica de la comida ultraprocesada fue también un 7%, 12%, 12%, y 17% más baja entre los participantes en el nivel ocupacional social más bajo, comparados con aquellos de las clases sociales altas. Los resultados sugieren que la contribución calórica de la comida ultraprocesada es más alta entre quienes proceden de niveles socioeconómicos más altos con una relación dosis-respuesta para las asociaciones establecidas
