Climate-change information, health-risk perception and residents' environmental complaint behavior: an empirical study in China.

Wang, Shanyong; Jiang, Jingjing; Zhou, Yu; Li, Jun; Zhao, Dingtao; Lin, Shoufu
| Idioma(s):
Motivating residents to deliver environmental complaints is beneficial for environmental authorities to help them manage environmental issues and alleviate the adverse effects caused by climate change. The major aim of the present study is to understand how climate-change information and residents' health-risk perceptions (both physical and mental dimensions) affect residents' environmental complaint behavior. The research framework was developed according to planned behavior theory, risk perception behavior and information behavior models. This framework was empirically assessed by employing questionnaire survey data gathered from 1273 respondents in China. The results indicate that climate-change information and residents' health-risk perceptions have all significantly positive effects on residents' attitudes toward environmental complaints and their intention to submit environmental complaints. Meanwhile, residents' health-risk perception is also positively affected by climate-change information. Mental health-risk perception plays a much stronger role in determining a residents' attitude and intention to submit an environmental complaint than does physical health-risk perception. Furthermore, attitude toward environmental complaint, perceived behavioral control and subjective norm all have significantly positive effects on a residents' intention to submit an environmental complaint. Additionally, this study also addresses the intention-behavior gap and suggests a positive relationship between intention and behavior. The present study may provide some practical implications to motivate residents to submit environmental complaints.

Maternal and Child Health Nutrition Faculty and Trainees Work Collaboratively with Community Partners to Assess Afterschool Nutrition Environments.

Barroso, Cristina; Spence, Marsha; Hill, Cheryl; Rodgers, Megan; Jennings, Krystal; Parkman, Kelsey; Waddill, Mary
| Idioma(s):
Purpose The purpose of this paper is to describe a collaborative service learning experience (SLE) which was part of the degree requirements of the Public Health Nutrition Graduate Program at the University of Tennessee. The SLE was collaboratively developed by the University of Tennessee's maternal and child health (MCH) nutrition leadership education and training (NLET) Program Director and the Knox County Health Department's healthy weight program manager. Description The SLE was a semester long project that included instructional time and fieldwork. Coursework focused on development of a community nutrition needs assessment, how to interpret and analyze assessment data, and how to use assessment data for program planning and policy development. Fieldwork consisted of interacting with an interprofessional team, assessing the nutrition environment at two afterschool sites, conducting a plate waste study to determine the amount of food consumed by children at the sites' dinner meals, interpreting and analyzing data, and developing and presenting recommendations for improvement. Assessment Trainees successfully completed all aspects of the SLE. They completed a community needs assessment of the neighborhoods surrounding the two afterschool program sites, conducted nutrition environment audits, including meal observations, and measured and analyzed plate waste from dinner meals served at the sites. Using the data gathered and collected, they prepared suggestions for nutrition environment improvements and policy development for community partners. Conclusion The SLE allowed trainees to develop MCH competencies and professional skills required in public health nutrition, while providing valuable data that subsequently was used to establish nutrition-related policies and interventions.

Understanding the Workplace Interactions of Young Adult Cancer Survivors With Occupational and Environmental Health Professionals.

Stone, Dawn S; Pavlish, Carol L; Ganz, Patricia A; Thomas, Elizabeth Anne; Casillas, Jacqueline N; Robbins, Wendie A
| Idioma(s):
Work provides satisfaction and stability to young adult cancer survivors. However, progressive health changes because of cancer may compromise safety and diminish functional ability. The purpose of this study was to describe long-term young adult cancer survivors' work experiences and describe their interactions with occupational and environmental health professionals (OEHPs) within the workplace. Cancer survivors were recruited from the Los Angeles County Cancer Surveillance Program. Professional organizations provided access to OEHPs. Constructivist grounded theory guided individual semi-structured interviews during data collection and analysis. Processes of interaction between cancer survivors and OEHPs found to influence work included revealing the survivor-self, sustaining work ability, gatekeeping (employment opportunities, return to work), and accessing support. OEHPs appeared to facilitate survivors' work ability in the long term if services were available, services were known to survivors, and survivors revealed needs. Educating workers about OEHP services throughout cancer experiences and survivorship could ultimately improve interactivity and provide supportive work environments.

Editorial Commentary: The Ever-changing Landscape of Health Care Economics-"The Future Ain't What It Used to Be".

Crall, Timothy S
| Idioma(s):
Payment models for orthopaedic services are constantly changing. Rather than have changes dictated to us, it is our responsibility as experts in arthroscopic surgery to advocate for patients and offer our unique insight to governmental agencies and payers. Before we can begin to understand this complex landscape, we need to start at the beginning and master the fundamentals of health care economics: cost-effectiveness analysis, cost minimization, cost benefit, and the like. Failure to do so will mean being left out of a conversation that will ultimately affect our ability to care for patients.

Toxicity and applications of surfactin for health and environmental biotechnology.

Santos, Vanessa Santana Vieira; Silveira, Edgar; Pereira, Boscolli Barbosa
| Idioma(s):
Characterized as one of the most potent biosurfactants, surfactin is a cyclic lipopeptide synthesized by several strains of Bacillus genus. The aim of this review was to present the physicochemical and structural properties of surfactin and to demonstrate advances and applications of this biosurfactant for health and environmental biotechnology. Further, this review also focused on toxicological effects of surfactin on in vivo and in in vitro systems. The hydrophobic nature of surfactin enables interaction with membrane-bound phospholipids and indicates the ability of the molecule to act as a new weapon with respect to therapeutic and environmental properties. Seeking to avoid environmental contamination produced by widespread use of synthetic surfactants, surfactin emerges as a biological control agent against pathogen species owing to its antibacterial and antiviral properties. In addition, the mosquitocidal activity of surfactin was suggested as new strategy to control disease vectors. The current findings warrant future research to assess the toxicity of surfactin to enable an optimizing anticancer therapy and to seek refined methodologies, including nanotechnology techniques, to allow for an improved delivery of the biogenic molecule on target cells.

Health Economic Evaluations of Digital Health Interventions for Secondary Prevention in Stroke Patients: A Systematic Review.

Valenzuela Espinoza, Alexis; Steurbaut, Stephane; Dupont, Alain; Cornu, Pieter; van Hooff, Robbert-Jan; Brouns, Raf; Putman, Koen
| Idioma(s):
BACKGROUND: In the first 5 years after their stroke, about a quarter of patients will suffer from a recurrent stroke. Digital health interventions facilitating interactions between a caregiver and a patient from a distance are a promising approach to improve patient adherence to lifestyle changes proposed by secondary prevention guidelines. Many of these interventions are not implemented in daily practice, even though efficacy has been shown. One of the reasons can be the lack of clear economic incentives for implementation. We propose to map all health economic evidence regarding digital health interventions for secondary stroke prevention. SUMMARY: We performed a systematic search according to PRISMA-P guidelines and searched on PubMed, Web of Science, Cochrane, and National Institute for Health Research Economic Evaluation Database. Only digital health interventions for secondary prevention in stroke patients were included and all study designs and health economic outcomes were accepted. We combined the terms "Stroke OR Cardiovascular," "Secondary prevention," "Digital health interventions," and "Cost" in one search string using the AND operator. The search performed on April 20, 2017 yielded 163 records of which 26 duplicates were removed. After abstract screening, 20 articles were retained for full-text analysis, of which none reported any health economic evidence that could be included for analysis or discussion. Key Messages: There is a lack of evidence on health economic outcomes on digital health interventions for secondary stroke prevention. Future research in this area should take health economics into consideration when designing a trial and there is a clear need for health economic evidence and models.

Training Community Residents to Address Social Determinants of Health in Underresourced Communities.

Wennerstrom, Ashley; Sliver, Julia; Pollock, Miranda; Gustat, Jeanette
| Idioma(s):
Disparities in chronic disease and life expectancy remain a significant public health problem and are largely attributable to social determinants of health. Community health workers (CHWs) promote health equity through individual- and community-level activities, and leadership and advocacy skills training make CHWs more likely to catalyze structural change. CHWs are increasingly being integrated into clinical practices to support care management, creating a need for new grassroots community-level advocates. We adapted for community residents an existing CHW training curriculum focused on social determinants of health and effecting community change. We offered 36 hours of training at community-based locations in New Orleans, Louisiana. We assessed baseline civic and community participation and pre- and postknowledge for each lesson. Among 43 enrollees, 42 completed the program. The majority were Black (92.7%), female (92.7%), and retired or unemployed (77.5%), with a median age of 61.5 years. In the past year, 85% of participants had volunteered, 57.1% had been involved with a community organization, and 32.4% had contacted the city council. Participants demonstrated statistically significant increases in knowledge in 5 of 6 lessons. Our success in increasing knowledge of advocacy among a civically engaged group suggests that trainees may become community leaders in addressing social determinants of health.

Environmental exposure and health effects in a highly polluted area of Northern Italy: a narrative review.

Alias, Carlotta; Benassi, Laura; Bertazzi, Luca; Sorlini, Sabrina; Volta, Marialuisa; Gelatti, Umberto
| Idioma(s):
Human health and well-being are strongly linked to the state of the environment. The high industrial pressure present in the Province of Brescia, located in Northern Italy, produced strong environmental and health concerns. This narrative review of the literature aims at identifying the studies focused on the association between exposure to environmental pollutants and health effects in the population living in this area. Thirteen papers fitted the inclusion criteria: five were focused on the connection among pollutants present in air matrix and health effects, seven on both air and soil, and one on soil. No study investigated the relationship with water pollution. The great variability in the analyzed end-points made it difficult to draw precise conclusions, but the fact that, in almost all the studies, the investigated health effects have a positive association with the exposure to different kinds of pollutants, allows us to hypothesize that the considered population is living in an area where the "environmental pressure" could produce significant health effects in the future.

Why public health matters today more than ever: the convergence of health and social policy.

Littlejohns, Lori Baugh; Smith, Neale; Townend, Louise
| Idioma(s):
We argue that public health matters more today than ever because it is uniquely positioned as a meeting point or fulcrum between health care and social welfare policy perspectives on the social determinants of health. It combines a grounding in the sciences of biomedicine and epidemiology with the moral imperatives of social advocacy. Health cannot be delivered through health care policy alone and neither can social welfare policy ensure the well-being of all citizens on its own. Social policy is at a disadvantage because it does not engender universal consent the way health policy can. While the way that illness should be addressed is debated, it should be addressed to be not contested, as is social welfare for vulnerable populations. The convergence of health and social policy to address the social determinants of health means public health advocacy must explicitly leverage biomedicine to provide materialist and substantive arguments and social welfare to provide the normative and moral arguments. We conclude that a new model of public health advocacy or social lobbying is necessary to effectively raise concerns that health care-focused thinking will not, but with potential heft that social welfare, historically, has not been able to command.
