RESUMO

IMPORTANCE: Arboviruses, particularly those transmitted by mosquitoes, pose a significant threat to humans and are an increasing concern because of climate change, human activity, and expanding vector-competent populations. West Nile virus is of significant concern as the most frequent mosquito-borne disease transmitted annually within the continental United States. Here, we identify a previously uncharacterized signaling pathway that impacts West Nile virus infection, namely endothelin signaling. Additionally, we demonstrate that we can successfully translate results obtained from D. melanogaster into the more relevant human system. Our results add to the growing field of insulin-mediated antiviral immunity and identify potential biomarkers or intervention targets to better address West Nile virus infection and severe disease.

RESUMO

Spillover of sarbecoviruses from animals to humans has resulted in outbreaks of severe acute respiratory syndrome SARS-CoVs and the ongoing COVID-19 pandemic. Efforts to identify the origins of SARS-CoV-1 and -2 has resulted in the discovery of numerous animal sarbecoviruses-the majority of which are only distantly related to known human pathogens and do not infect human cells. The receptor binding domain (RBD) on sarbecoviruses engages receptor molecules on the host cell and mediates cell invasion. Here, we tested the receptor tropism and serological cross reactivity for RBDs from two sarbecoviruses found in Russian horseshoe bats. While these two viruses are in a viral lineage distinct from SARS-CoV-1 and -2, the RBD from one virus, Khosta 2, was capable of using human ACE2 to facilitate cell entry. Viral pseudotypes with a recombinant, SARS-CoV-2 spike encoding for the Khosta 2 RBD were resistant to both SARS-CoV-2 monoclonal antibodies and serum from individuals vaccinated for SARS-CoV-2. Our findings further demonstrate that sarbecoviruses circulating in wildlife outside of Asia also pose a threat to global health and ongoing vaccine campaigns against SARS-CoV-2.

RESUMO

This case study describes the country-level response to the COVID-19 pandemic in Kenya between February 2020 and May 2021. We organize the presentation of COVID-19 response strategies across the five stages of (a) engagement, (b) assessment, (c) planning, (d) action/implementation, and (e) evaluation. We describe the participatory monitoring and evaluation (M&E) process implemented in collaboration with the WHO Regional Office for Africa Monitoring and Evaluation Team. The M&E system was used to organize and make sense of emerging data regarding specific response activities and changing COVID incidence. We share the results of that collaborative sensemaking, with particular attention to our analysis of the factors that facilitated and those that impeded our pandemic response. We conclude with lessons learned and practical implications from Kenya's experience to help guide future country-level responses to rapidly changing public health crises.

RESUMO

As the COVID-19 pandemic swept throughout the world, it created a demand for information to help understand the public health response and its effects. Limited capacity to see and interpret data-"sensemaking" with measures of progress-affects the use of data for quality improvement. The World Health Organization Regional Office for Africa (WHO AFRO) supported partners from the Member States in using a participatory monitoring and evaluation system to document and systematically reflect on the COVID-19 response at the country level. The WHO AFRO's COVID-19 Response Monitoring and Evaluation (M&E) team captured and communicated response activities based on available reports from 35 of the 47 member countries. By reviewing reports and communications, the M&E team documented nearly 8,000 COVID-19 response activities during the study period (January 2020 through July 2021). A "sensemaking" protocol was used to support country partners in identifying factors associated with increases or decreases in both new cases and response activities. This report describes this participatory M&E approach and process of shared sensemaking. We illustrate with a country-level case study of the COVID-19 response in the Africa Region.

RESUMO

This report describes an Equity Lens Protocol and its use to guide partners' systematic reflection on harms and mitigation strategies of the COVID-19 response in a local public health system. This process evaluation tool is based on the Guidance document for assuring an equitable response to COVID-19 prepared by the Pan American Health Organization. We used a participatory approach to engage public health partners in systematically reflecting on harms, mitigation strategies, and lessons learned and implications for practice. Outputs from using this tool included identified: (a) specific harms (e.g., loss of income and challenges to learning) related to particular COVID-19 response measures (e.g., home confinement and school closure) and (b) mitigation strategies implemented to reduce harms. In response to the protocol's guiding questions, partners also identified lessons learned and practice recommendations for strengthening equity work in public health responses (e.g., an equitable response requires an investment in people, structures, and relationships before a crisis). This report-and accompanying protocol-illustrates use of a practical method for systematic reflection on public health responses through an equity lens.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic tested the capacity of local health systems to understand and respond to changing conditions. Although data on new cases of COVID-19 were widely shared in communities, there was less information on the multisector response activities and factors associated with implementation. To address this gap, this empirical case study examined (a) the pattern of implementation of COVID-19 response activities and (b) the factors and critical events associated with both the pattern of new cases and the implementation of the local COVID-19 response. We used a participatory monitoring and evaluation system to capture, code, characterize, and communicate 580 COVID-19 response activities implemented in the city of Lawrence and Douglas County, Kansas. Collaboration across sectors including public health, medical services, city/county government, businesses, social services, public schools, and universities enabled the local public health system's response effort. Documentation results showed the varying pattern of new COVID-19 cases and response activities over time and the factors identified as enabling or impeding the response and related new cases. Similar participatory monitoring and evaluation methods can be used by local health systems to help understand and respond to the changing conditions of COVID-19 response and recovery.

RESUMO

INTRODUCTION: Expert opinion suggests that efforts to address childhood obesity should seek to transform the environments in which children operate. The objective of this study was to describe the extent to which multisetting programs and policies interact with community and child predictors and are associated with child body mass index (BMI) in the 130 US communities participating in the Healthy Communities Study. METHODS: For 2 years beginning in fall 2013, we collected data through key informant interviews on community programs and policies related to healthy weight among children that occurred in the 10 years before the interview. We characterized community programs and policies by intensity of efforts and the number of settings in which a program or policy was implemented. Child height and weight were measured during household data collection. We used multilevel modeling to examine associations of community programs and policies in multiple settings and child and community predictors with BMI z scores of children. RESULTS: The mean number of settings in which community policies and programs were implemented was 7.3 per community. Of 130 communities, 31 (23.8%) implemented community programs and policies in multiple settings. Higher-intensity community programs and policies were associated with lower BMI in communities that used multiple settings but not in communities that implemented programs and policies in few settings. CONCLUSION: Efforts to prevent childhood obesity may be more effective when community programs and policies are both intensive and are implemented in multiple settings in which children live, learn, and play.

RESUMO

Implementation of the Ebola response was credited with reducing incidence of Ebola virus disease (EVD) in West Africa; however little is known about the amount and kind of Ebola response activities that were ultimately successful in addressing the 2014 outbreak. We collaboratively monitored Ebola response activities and associated effects in Margibi County, Liberia, a rural county in Liberia deeply affected by the outbreak. We used a participatory monitoring and evaluation system, including key informant interviews and document review, to systematically document activities, code them, characterize their contextual features, and discover and communicate patterns in Ebola response activities to essential stakeholders. We also measured incidence of EVD over time. Results showed a distinct pattern in Ebola response activities and key events, which corresponded with subsequent decreased EVD incidence. These data are suggestive of the role of Ebola response activities played in reducing the incidence of EVD within Margibi County, which included implementing safe burials, social mobilization and community engagement and case management. Systematic monitoring and evaluation of response activities to control disease outbreaks holds lessons for implementing and evaluating similar comprehensive and multi-sectoral community health efforts.

RESUMO

Although credited with ultimately reducing incidence of Ebola Virus Disease (EVD) in West Africa, little is known about the amount and kind of Ebola response activities associated with reducing the incidence of EVD. Our team monitored Ebola response activities and associated effects in two rural counties in Liberia highly affected by Ebola. We used a participatory monitoring and evaluation system, and drew upon key informant interviews and document review, to systematically capture, code, characterize, and communicate patterns in Ebola response activities. We reviewed situation reports to obtain data on incidence of EVD over time. Results showed enhanced implementation of Ebola response activities corresponded with decreased incidence of EVD. The pattern of staggered implementation of activities and associated effects-replicated in both counties-is suggestive of the role of Ebola response activities in reducing EVD. Systematic monitoring of response activities to control disease outbreaks holds lessons for implementing and evaluating multi-sector, comprehensive community health efforts.

RESUMO

Although the importance of health care access is widely acknowledged, less is known about how partnerships can help assure access to quality health services for those experiencing health inequities. This report describes implementation of collaborative efforts through the Health Access Committee of the Latino Health for All Coalition (Wyandotte County/Kansas City, Kansas) to address its three goal areas (1) improving cultural competence through organizational change, (2) improving access to quality health services through access to diabetes prevention services, and (3) improving access and linkage to care via enrollment in health insurance. Using community-based participatory approaches, we documented and reflected on the pattern of activities facilitated by the coalition and its partners for each goal area over a 1-year period. This case report outlines strategies, activities, and lessons learned by coalition partners. This article offers practical guidance about how to structure and implement a coalition that provides technical support for increasing health care access and cultural competency.

RESUMO

Climate change is a social justice as well as an environmental issue. The magnitude and pattern of changes in weather and climate variables are creating differential exposures, vulnerabilities, and health risks that increase stress on health systems while exacerbating existing and creating new health inequities. Examples from national and local health adaptation projects highlight that developing partnerships across sectors and levels are critical for building climate-resilient health systems and communities. Strengthening current and implementing new health interventions, such as using environmental information to develop early warning systems, can be effective in protecting the most vulnerable. However, not all projected risks of climate change can be avoided by climate policies and programs, so health system strengthening is also critical. Applying a health inequity lens can reduce current vulnerabilities while building resilience to longer-term climate change. Taking inequities into account is critical if societies are to effectively prepare for and manage the challenges ahead.

RESUMO

Successful implementation of the Affordable Care Act (ACA) depends on the capacity of local communities to mobilize for action. Yet the literature offers few systematic investigations of what communities are doing to ensure support for enrollment. In this empirical case study, we report implementation and outcomes of Enroll Wyandotte, a community mobilization effort to facilitate enrollment through the ACA in Wyandotte County, Kansas. We describe mobilization activities during the first round of open enrollment in coverage under the ACA (October 1, 2013-March 31, 2014), including the unfolding of community and organizational changes (e.g., new enrollment sites) and services provided to assist enrollment over time. The findings show an association between implementation measures and newly created accounts under the ACA (the primary outcome).

RESUMO

Considering the Arctic Ocean (including sea ice) as a defined volume, we develop equations describing the time-varying fluxes of mass, heat and freshwater (FW) into, and storage of those quantities within, that volume. The seasonal cycles of fluxes and storage of mass, heat and FW are quantified and illustrated using output from a numerical model. The meanings of 'reference values' and FW fluxes are discussed, and the potential for error through the use of arbitrary reference values is examined.

RESUMO

The case study analyzes the effects of training and technical assistance on the amount of community changes facilitated by members of a community coalition to prevent adolescent substance use. The study examines the sustainability of these changes in the community over time. The coalition implemented a Community Change Intervention that focused on building coalition capacity to support implementation of community changes-program, policy, and practice changes. Over the 2-year intervention period, there were 36 community changes facilitated by the coalition to reduce risk for adolescent substance use. Results showed that the coalition facilitated an average of at least 3 times as many community changes (i.e., program, policy and practice changes) per month following the intervention. Action planning was found to have accelerated the rate of community changes implemented by the coalition. After the intervention there was increased implementation of three key prioritized coalition processes: Documenting Progress/Using Feedback, Making Outcomes Matter, and Sustaining the Work. A 1-year probe following the study showed that the majority of the community changes were sustained. Factors associated with the sustainability of changes included the continued development of collaborative partnerships and securing multiyear funding.

RESUMO

OBJECTIVE: To measure the progress made by the collaborative actions of multisectorial partners in a community health effort using a systematic method to document and evaluate community/system changes over time. METHODS: This was a community-based participatory research project engaging community partners of the Latino Health for All Coalition, which based on the Health for All model, addresses health inequity in a low-income neighborhood in Kansas City, Kansas, United States of America. Guided by three research questions regarding the extent to which the Coalition catalyzed change, intensity of change, and how to visually display change, data were collected on community/system changes implemented by the community partners from 2009-2012. These changes were characterized and rated according to intensity (event duration, population reach, and strategy) and by other categories, such as social determinant of health mechanism and sector. RESULTS: During the 4-year study period, the Coalition implemented 64 community/system changes. These changes were aligned with the Coalition's primary goals of healthy nutrition, physical activity, and access to health screenings. Community/system efforts improved over time, becoming longer in duration and reaching more of the population. CONCLUSIONS: Although evidence of its predictive validity awaits further research, this method for documenting and characterizing community/system changes enables community partners to see progress made by their health initiatives.

RESUMO

Health promotion and social determinants of health approaches, when integrated, can better contribute to understanding and addressing health inequities. Yet, they have typically been pursued as two solitudes. This paper presents the key elements, principles, actions, and potential synergies of these complementary frameworks for addressing health equity. The value-added of integrating these two approaches is illustrated by three examples drawn from the authors' experiences in the Americas: at the community level, through a community-based coalition for reducing chronic disease disparities among minorities in an urban center in the United States; at the national level, through healthy-settings interventions in Canada; and at the Regional level, through health cooperation based on social justice values in Latin America. Challenges to integrating health promotion and social determinants of health approaches in the Americas are also discussed.

RESUMO

West Nile virus (WNV) is the most prevalent mosquito-borne virus in the United States with approximately 2,000 cases each year. There are currently no approved human vaccines and a lack of prophylactic and therapeutic treatments. Understanding host responses to infection may reveal potential intervention targets to reduce virus replication and disease progression. The use of Drosophila melanogaster as a model organism to understand innate immunity and host antiviral responses is well established. Previous studies revealed that insulin-mediated signaling regulates WNV infection in invertebrates by regulating canonical antiviral pathways. Because insulin signaling is well-conserved across insect and mammalian species, we sought to determine if results using D. melanogaster can be extrapolated for the analysis of orthologous pathways in humans. Here, we identify insulin-mediated endothelin signaling using the D. melanogaster model and evaluate an orthologous pathway in human cells during WNV infection. We demonstrate that endothelin signaling reduces WNV replication through the activation of canonical antiviral signaling. Taken together, our findings show that endothelin-mediated antiviral immunity is broadly conserved across species and reduces replication of viruses that can cause severe human disease. IMPORTANCE: Arboviruses, particularly those transmitted by mosquitoes, pose a significant threat to humans and are an increasing concern because of climate change, human activity, and expanding vector-competent populations. West Nile virus is of significant concern as the most frequent mosquito-borne disease transmitted annually within the continental United States. Here, we identify a previously uncharacterized signaling pathway that impacts West Nile virus infection, namely endothelin signaling. Additionally, we demonstrate that we can successfully translate results obtained from D. melanogaster into the more relevant human system. Our results add to the growing field of insulin-mediated antiviral immunity and identifies potential biomarkers or intervention targets to better address West Nile virus infection and severe disease.

RESUMO

This case study describes the Enough Abuse Campaign, a multidisciplinary, statewide effort to prevent child sexual abuse in Massachusetts. The study uses the Institute of Medicine's Framework for Collaborative Community Action on Health to provide a systematic description of the campaign's process of implementation, which includes: (a) developing a state-level infrastructure for child sexual abuse prevention, (b) assessing child sexual abuse perceptions and public opinion, (c) developing local infrastructures in three communities and implementing training programs focused on preventing perpetration of child sexual abuse, (d) facilitating changes in local communities to child-sexual-abuse-related systems, and (e) inviting Massachusetts residents to join an advocacy-based movement to prevent child sexual abuse. This case study concludes with future directions for the campaign and topics for future research related to child sexual abuse.

RESUMO

Illness caused by hantaviruses is often severe and is typically characterized by diffuse pulmonary disease or renal insufficiency depending on the type of hantavirus. Here we report 2 cases of hantavirus infection that resulted in severe cognitive impairment but did not have any pulmonary or renal manifestations. These 2 cases may be indicative of previously underreported symptoms of hantavirus infection and might represent examples of hantavirus-related encephalopathy.
