Agricultural workers, designated as "essential" at the start of the COVID-19 pandemic, work in harsh labor conditions, and now have the added challenge of continuing to work during the COVID-19 pandemic. The aim of this study was to assess agricultural workers' COVID-19 related history, employer-based safety measures, individual preventive practices, and COVID-19 vaccination uptake. A questionnaire study was conducted among agricultural workers in Central Florida about COVID-19 during the month of June 2020 and again in July 2021. Among 92 agricultural workers in June 2020, 47% were obese; 11% had had a COVID-19 nasal test; 87% were able to social distance at work and 34% reported employer provided face masks; 15% reported not willing to get the COVID-19 vaccine and 25% were unsure. 40% could self-isolate if they contracted COVID-19. In a follow-up visit in July 2021, 53% of participants reported receiving a COVID-19 vaccine. Agricultural workers are particularly vulnerable to COVID-19 due to existing health risk factors and lack of essential protective resources. Occupational health protections social safety net programs are urgently needed to prevent infections in vulnerable workers, and reduce community spread, and increase COVID-19 vaccination rates.

With the recent impact by the COVID‐19 pandemic, nursing research has gone through unexpected changes across the globe. The purpose of this special report is to present the commonalities in the impact of the COVID‐19 pandemic on nursing research across four countries, including the United States, South Korea, Japan, and Taiwan, and one region, that is, Hong Kong, and to make recommendations for future nursing research during the immediate postpandemic period and future pandemic situations. To identify the commonalities, seven researchers/leaders from the five countries/regions had discussions through 3 days of an international workshop. The content for this discussion paper derived from: (a) the exemplars/cases of the COVID‐19 impact on the research process, (b) researchers/leaders' presentations on the COVID‐19 impact, and (c) memos from the workshop. The materials were analyzed using a simple content analysis. The commonalities included: (a) “a heavy emphasis on teaching and fluctuating productivity,” (b) “increased funding opportunities and governmental support,” (c) “gendered experience complicated by professional differences,” (d) “delays and changes/modifications in research process,” (e) “limited research settings and difficulties in getting access,” and (f) “increased online dissemination activities with positive changes in the image of nursing.” With all collective wisdom that nurse researchers have obtained during the COVID‐19 pandemic, nursing research will evolve again for the successful future of the nursing discipline.

Globally, there is increasing recognition that agricultural workers are at risk for chronic kidney disease of unknown etiology (CKD u). Recurrent heat exposure, physical exertion, dehydration, muscle damage, and inflammation are hypothesized to contribute to the development of CKD u, but the relative importance of these processes and the interactions among them remain unclear. Moreover, there is a need to identify biomarkers that could distinguish individuals who are at greatest risk for kidney damage to target preventative interventions for CKD u. In this study, we evaluated dehydration and markers of inflammation, muscle damage, and renal function in agricultural workers at a non-workday baseline assessment. Urine specific gravity and kidney function were measured before and after work shifts on three subsequent days, and heat index, core body temperature, and heart rate were monitored during the work shifts. A combination of direct comparisons and machine learning algorithms revealed that reduced levels of uromodulin and sodium in urine and increased levels of interleukin-6 and C-reactive protein in serum were indicative of dehydration at baseline, and that dehydration, high body mass index, reduced urine uromodulin, and increased serum interleukin-6, C-reactive protein, and lipopolysaccharide-binding protein at baseline were predictive of acute kidney injury on subsequent workdays. Our findings suggest a method for identifying agricultural workers at greatest risk for kidney injury and reveal potential mechanisms responsible for this process, including pathways overlapping in dehydration and kidney injury. These results will guide future studies confirming these mechanisms and introducing interventions to protect kidney health in this vulnerable population.

Introduction: Agricultural workers perform intense labor outside in direct sunlight and in humid environmental conditions exposing them to a high risk of heat-related illness (HRI). To implement effective cooling interventions in occupational settings, it is important to consider workers’ perceptions. To date, an analysis of agricultural workers’ experience and perception of cooling devices used in the field while working has not been published. Methods: Qualitatively data from 61 agricultural workers provided details of their perceptions and experiences with cooling interventions. Results: The participants in the bandana group reported the bandana was practical to use at work and did not interfere with their work routine. Cooling vest group participants agreed that the vest was effective at cooling them, but the practicality of using the vest at work was met with mixed reviews. Conclusion: The findings of this qualitative study support and extend existing research regarding personal cooling and heat prevention research interventions with vulnerable occupational groups. Personal cooling gear was well received and utilized by the agricultural workers. Sustainable heat prevention studies and governmental protection strategies for occupational heat stress are urgently needed to reduce the risk of heat-related morbidity, mortality, and projected climate change health impacts on outdoor workers.

The purpose of this article is to identify the commonalities in nursing perspectives among 6 countries/regions (United States, South Korea, Taiwan, Japan, Hong Kong, and Thailand). Nine leaders from the 6 countries/regions reflected on what nursing perspectives were in their own countries/regions and provided exemplars/cases from their own experiences and literature reviews. The data were analyzed using a content analysis. Seven themes were extracted: (a) "embedded in cultural and historical contexts"; (b) "based on philosophical pluralism"; (c) "women-centered perspectives"; (d) "care-oriented holistic views"; (e) "ethical and humane views"; (f) "respecting and advocating"; and (g) "considering diversities."

Background COVID-19 has tested the capacity of every nursing school, but its impact has varied according to the size, location, and baseline infrastructure of each school. This makes the pandemic an important lens through which to study crisis management principles, such as flexibility and scalability (the ability to expand and reduce efforts based on situational demands). Purpose This article provides a roadmap for academic crisis management, modeled on the National Incident Management System (NIMS). It is tailored to the unique needs of nursing schools and applies COVID-19 as a case study. Methods The authors explore the elements of the NIMS that were deployed within 1 top-ranked school of nursing during COVID-19. Results and conclusions The article includes best practices, tips, and resources to help academic nurse leaders and educators navigate large-scale or unprecedented crises, such as COVID-19.

Background Adverse health effects among agricultural workers due to chronic heat exposure have been characterized in the literature as not only due to high ambient temperatures but also due to intensive manual labor in hot and humid conditions. The aim of this study was to use biomonitoring equipment to examine the effectiveness of selected cooling devices at preventing agricultural workers from exceeding the core body temperature threshold of 38.0°C (Tc38) and attenuating heat-related illness symptoms. Methods A convenience sample of 84 agricultural workers in Florida was randomized to one of four groups: (a) no intervention, clothing as usual; (b) cooling bandana; (c) cooling vest; and (d) both the cooling bandana and cooling vest. Biomonitoring equipment worn by the participants included core body temperature monitor and an accelerometer to capture physical activity. Findings A total of 78 agricultural workers completed one intervention workday trial. Compared with the control group, the bandana group had lower odds of exceeding Tc38 (odds ratio [OR] = 0.7, 90% confidence interval [CI] = [0.2, 3.2]) and the vest group had higher odds of exceeding Tc38 (OR = 1.8, 90% CI = [0.4, 7.9]). The simultaneous use of cooling vest and bandana showed an effect little different from the control group (OR = 1.3, 90% CI = [0.3, 5.6]). Conclusion/Application to Practice This is the first field-based study to examine cooling intervention among agricultural workers in the United States using biomonitoring equipment. This study found that using a bandana while working in a hot agricultural environment has the potential to be protective against exceeding the recommended Tc38 threshold.

Facing the onset of the COVID-19 pandemic and increasing outbreaks among farmworkers and food processing workers across the nation, the Oregon Occupational Health and Safety Administration (OR OSHA) issued temporary regulations, in contrast to optional recommendations, in late spring. These regulations aimed to reduce the risk of COVID-19 transmission among farmworkers, but made compromises that may fail to reduce the risk of further outbreaks among Oregon's agricultural workers, particularly those living in agricultural labor housing. Instead of considering the scientific literature that called for attention to space and length of time for social distancing among unrelated persons in indoor areas, the agency accepted the 6-foot social distancing rule of thumb and allowed even shorter distances between beds with the installation of plastic or plywood barriers. The 6-foot distance (or less with a barrier) between people sleeping next to each other in poorly ventilated housing has proved disastrous. Additionally, testing for migrant and seasonal farmworkers is neither uniform nor thorough, and little data have been collected to assess the success of existing testing efforts. New regulations must be adopted for farm labor housing that limit occupancy to at most two unrelated individuals for a room of 200 square feet; include expanded specification on the provision of fresh air in shared living spaces; and support increased access to testing, surveillance testing, and alternative safe housing at labor housing sites for identified cases.

Background In 2004, the American Association of Colleges of Nursing (AACN) called for all nursing schools to phase out master's-level preparation for advanced practice registered nurses (APRNs) and transition to doctor of nursing practice (DNP) preparation only by 2015. Today, five years after the AACN's deadline, nursing has not yet adopted a universal DNP standard for APRN practice entry. Purpose The purpose of this paper is to examine the factors influencing the ability of nursing schools to implement a universal DNP standard for APRNs. Methods Deans from top-ranked nursing schools explore the current state of the DNP degree in the US. The authors draw upon their collective experience as national leaders in academic nursing, long-time influencers on this debate, and heads of DNP programs themselves. This insight is combined with a synthesis of the literature and analysis of previously unpublished data from the AACN on trends in nursing doctoral education. Findings This paper highlights issues such as the long history of inconsistency (in messaging, curricula, etc.) surrounding the DNP, certification and accreditation challenges, cost barriers, and more. The authors apply COVID-19 as a case study to help place DNP graduates within a real-world context for health system stakeholders whose buy-in is essential for the success of this professional transition. Discussion This paper describes the DNP's standing in today's professional environment and advances the conversation on key barriers to its adoption. Insights are shared regarding critical next steps to ensure national acceptance of the DNP as nursing's terminal practice degree.

To estimate the impact of hydration interventions on postworkday hydration status and incidence of acute kidney injury (AKI).Thirty agricultural workers were first monitored on a workday without any interventions. On the intervention workday, the same workers were randomized to one of two groups: 169 ounces (oz) (5 L) of plain water (n = 16) or 169 oz (5L) of water with electrolytes (n = 14).No participants in the electrolyte group had an estimate glomerular filtration rate (eGFR) at the end of the workday of less than 90 mL/min/1.73 m2 or met the criteria for AKI in comparison to the water group (eGFR90: 15%; AKI: 23%) or the control group (eGFR90: 28%; AKI: 18%).The study showed that drinking water with electrolytes may lower the risk for development of AKI among agricultural workers.

To examine the health status of Hispanic agricultural workers in Florida and Georgia. Health data from agricultural workers in the Farm Worker Family Health Program (June 2019) and research studies in Florida (May 2015 and May 2019) were examined. Data from 728 agricultural workers were collected through sociodemographic questionnaire and clinical data. In the Florida sample, 83% were overweight or obese, 70% elevated blood pressure, 60% met the definition of prediabetes. In Georgia, 64% were overweight or obese and 67% had elevated blood pressure. Weak correlations were observed between BMI and systolic blood pressure (unadjusted r = 0.20), diastolic blood pressure (unadjusted r = 0.19), and glucose (unadjusted r = 0.14). Adjusting for age and gender did not show statistically significant correlation between BMI and systolic and diastolic blood pressure or glucose. While BMI has been shown to be strongly associated with high blood pressure and impaired glucose, we found a weak correlation among agricultural workers. Given the common and high use of pesticides and elevated rates of hypertension, impaired glucose, and adiposity in agricultural workers, the public health impact of this relationship may require and lead to occupational reform that protects the health of agricultural workers. Future studies should assess occupational and environmental factors and lifestyle differences between agricultural workers and the general population to better understand these discrepancies in health status.

With expected increases in extreme weather, there may be a greater risk of injury from extreme heat in outdoor worker populations. To plan for future adaptation measures, studies are needed that can characterize workers’ physiologic responses to heat in outdoor settings such as agriculture. The objective of this study was to characterize occupational heat exposure, key vulnerability factors (e.g., gender, energy expenditure), and physiologic heat stress response in a sample of fernery workers. Forty-three fernery workers over 86 workdays were examined regarding heat-related illness (HRI) during the summer months of 2012 and 2013. The key outcome measure was whether a participant’s body core temperature (Tc) reached or exceeded 38.0°C (100.4ºF; Tc38). Participants’ Tc exceeded 38.0°C on 49 (57%) of the workdays, with 30 of 40 participants reaching or exceeding Tc38 on at least one workday. Adjusting for sex, there was a 12% increase in the odds of Tc38 for every 100 kilocalories of energy expended (OR: 1.12; 95% Confidence Interval [CI]: [1.03, 1.21]). Adjusting for energy expenditure, females had 5 times greater odds of Tc38 compared with males (OR: 5.38; 95% CI: [1.03, 18.30]). These findings provide evidence of elevated Tc in Florida fernery workers, indicating an increased risk of occupational HRI, and the need for policy and interventions to address this health risk.

For the past two decades, agricultural workers in regions of Central America have reported an epidemic of chronic kidney disease of undetermined etiology (CKDu) that is not associated with established risk factors of chronic kidney disease. Several hypotheses have emerged, but the etiology of CKDu remains elusive and controversial. The aim of this literature review was to describe the potential risk factors of CKDu in Mesoamerica and implications for the U.S. agricultural worker population. PubMed and CINAHL databases were searched for articles published between 2000 and 2018 that examined CKDu in Mesoamerica; 29 original studies were included in this review. CKDu is a multifactorial disease that is often asymptomatic with hallmark characteristics of elevated serum creatinine and blood urea nitrogen (BUN), low glomerular filtration rate, electrolyte abnormalities, and non-nephrotic proteinuria. Reducing the global prevalence of CKDu will require more robust studies on causal mechanisms and on interventions that can reduce morbidity and mortality in vulnerable populations.

(1) Polybrominated diphenyl ethers (PBDEs) were widely produced in the United States until 2004 but remain highly persistent in the environment. The potential for PBDEs to disrupt normal neuroendocrine pathways resulting in depression and other neurological symptoms is largely understudied. This study examined whether PBDE exposure in pregnant women was associated with antenatal depressive symptomatology. (2) Data were collected from 193 African American pregnant women at 8–14 weeks gestation. Serum PBDEs and depressive symptoms were analyzed and a mixture effect was calculated. (3) Urban pregnant African American women in the Southeastern United States had a high risk of depression (27%) compared to the National average. Increased levels of PBDEs were found. BDE-47 and -99 exposures are significantly associated with depressive symptomatology in the pregnant cohort. The weighted body burden estimate of the PBDE mixture was associated with a higher risk of mild to moderate depression using an Edinburgh Depression Scale cutoff score of ≥10 (OR = 2.93, CI 1.18, 7.82). (4) Since antenatal depression may worsen in postpartum, reducing PBDE exposure may have significant clinical implications.

Background Since its founding, professional nursing has applied an environmental lens to healing. Methods This CANS 2020 Keynote article describes the history of nursing environmental science and nurses important contributions to the US Environmental Justice Movement. Starting with Florence Nightingale's Notes on Nursing, which established Environmental Theory, the paper introduces key figures throughout nursing history who have studied and advocated for environmental health and justice. Findings The paper emphasizes that nursing has always been about environmental health and that, regardless of specialty or practice setting, all nurses are called to incorporate environmental science and translation into their research and practice. Conclusion This call to action is especially critical today in the context of urgent issues like climate change, environmental racism and racial health disparities, emerging infectious diseases like COVID-19, and chemical exposures in the home and workplace (among others).

Background There is a compelling need to identify agricultural workers at risk for heat related illness (HRI). Methods Data from Florida agricultural workers (N = 221) were collected over 3 summer workdays (2015 to 2017) to examine risk factors for exceeding NIOSH-recommended core temperature (Tc) thresholds (38 °C [Tc38] and 38.5 °C [Tc38.5]) using generalized linear mixed models. Results On an average workday, 49% of participants exceeded Tc38 and 10% exceeded Tc38.5. On average, participants first exceeded both thresholds early in the day; the Tc38 threshold mid-morning (10:38 AM), and Tc38.5 about a half hour later (11:10 AM). Risk factors associated with exceeding Tc38 included years working in US agriculture, body mass index, time performing moderate-to-vigorous physical activity, increasing heat index, and field crop work. Conclusions The high prevalence of core temperatures exceeding recommended limits emphasizes the serious need for mandated HRI prevention programs for outdoor workers.

Background As global temperatures rise, increasing numbers of individuals will work in hot environments. Interventions to protect their health are critical, as are reliable methods to measure the physiological strain experienced from heat exposure. The physiological strain index (PSI) is a measure of heat strain that relies on heart rate and core temperature but is challenging to calculate in a real-world occupational setting. Methods We modified the PSI for use in field settings where resting temperature and heart rate are not available and used the modified physiological strain index (mPSI) to describe risk factors for high heat strain (mPSI ≥ 7) experienced by agricultural workers in Florida during the summers of 2015 through 2017. mPSI was calculated for 221 workers, yielding 465 days of data. Results A higher heat index (β = 0.185; 95% CI: 0.064, 0.307) and higher levels of physical activity at work (0.033; 95% CI: 0.017, 0.050) were associated with a higher maximum mPSI. More years worked in US agriculture (-0.041; 95% CI: -0.061, -0.020) were protective against a higher maximum mPSI. Out of 23 workdays that a participant experienced a maximum mPSI ≥ 7, 22 were also classified as strained by at least one other measure of high heat strain (core temperature [Tc] >38.5°C, sustained heart rate >(180 - age), and mean heart rate > 115 bpm). Conclusions This study provides critical information on risk factors for elevated heat strain for agricultural workers and suggests a practical approach for using PSI in field-based settings.

Nurses are well-positioned to be groundbreaking researchers, scientists, leaders, and innovators to improve the health and well-being of individuals, families, and communities. Nurse scientists are needed to contribute to scientific discoveries that inform effective strategies to improve patient care and outcomes and to inform future policies. Thoughtful consideration is required about the preparation of nurse scientists to ensure they are equipped with the knowledge and skill sets to meet the needs of society. Evolving health needs and priority areas of inquiry along with an ever-increasing array of sophisticated methodologies and centrality of interdisciplinary teams to solve complex problems should drive how we prepare PhD students. This paper reflects a panel and subsequent dialogue with nurse leaders at the PhD summit held at the University of Pennsylvania in October 2019. Three aspects of PhD education and the advancement of nursing science are discussed 1) examining important elements to support nurse scientist development; 2) identifying key gaps in science that the discipline needs to address in educating the next generation of nurse scientists; and 3) preparing nurse scientists for the competitive funding environment.

Background The purpose of this systematic review is to examine cooling intervention research in outdoor occupations, evaluate the effectiveness of such interventions, and offer recommendations for future studies. This review focuses on outdoor occupational studies conducted at worksites or simulated occupational tasks in climatic chambers. Methods This systematic review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. PubMed, Embase, and Web of Science were searched to identify original research on intervention studies published in peer-reviewed journals that aimed at reducing heat stress or heat-related illness from January 2000 to August 2020. Results A systematic search yielded a total of 1042 articles, of which 21 met the inclusion criteria. Occupations with cooling intervention studies included agriculture (n = 5), construction (n = 5), industrial workers (n = 4), and firefighters (n = 7). The studies focused on multiple types of cooling interventions cooling gear (vest, bandanas, cooling shirts, or head-cooling gel pack), enhanced heat dissipation clothing, forearm or lower body immersion in cold water, water dousing, ingestion of a crushed ice slush drink, electrolyte liquid hydration, and modified Occupational Safety and Health Administration recommendations of drinking water and resting in the shade. Conclusion Current evidence indicates that using multiple cooling gears along with rest cycles may be the most effective method to reduce heat-related illness. Occupational heat-related illnesses and death may be mitigated by targeted cooling intervention and workplace controls among workers of vulnerable occupational groups and industries.

In 2015, Ethiopia's first PhD in nursing program was established in collaboration between the Addis Ababa University (AAU) and Emory University Schools of Nursing. Eleven students have entered the program since its inception, six have successfully defended their proposals, one has graduated, and two have received Fogarty Global Health Fellowships. This paper describes the evolution of this international partnership and the innovative processes and mechanisms involved in program implementation; the authors address the description of the program, central implementation challenges, notable outcomes, and student achievements. One key implementation challenge has been that, although nursing is one of the largest healthcare workforces in Ethiopia, nurses remain underutilized and undervalued in the workplace. This treatment is due, in part, to limited professional regulations, leading some of the PhD students to apply their leadership skills to advocate for national practice reform. According to students, the PhD program has been a means not only to improve nursing research capacity and education in Ethiopia, but also to generate the regulations necessary for graduates to practice according to their degree. While the opportunity to generate knowledge is vitally important, students also value the chance to transform the profession of nursing.

Objectives To analyze the predictors of health care utilization among respondents to the National Agricultural Worker Survey. Specifically, we hypothesized that English proficiency would predict utilization of health care services within the last 2 years. Methods Using the 2015-2016 National Agricultural Worker Survey, we performed a secondary data analysis to analyze the predictors of health care utilization within the last 2 years in the United States' agricultural worker population. Data were cleaned and analyzed using decision tree analysis, which produced a classification tree model that was trained on 90% of the data and validated on 10%. Results Exposure to English was not a predictor of health care utilization in our classification tree. The first major partition that predicted utilization was insurance status. Additional partitions were on age, gender, hypertension diagnosis, and public aid. Conclusions By partitioning on insurance status and use of public aid, the decision tree provided evidence that systemic factors are key determinants of health care utilization in the agricultural worker community. This highlights the importance of agencies that connect agricultural workers with resources that provide insurance and improve access to health care. This is especially important given that agricultural workers are one of the highest risk groups for occupational injury or death in the United States.

Recent findings suggest that laboring in hot occupational environments is related to kidney damage in agricultural workers. We examined hydration status and kidney function in 192 Florida agricultural workers.Blood and urine samples were collected over 555 workdays during the summers of 2015 and 2016. Urine-specific gravity (USG), serum creatinine, and other kidney function markers were examined pre- and post-shift on each workday. Multivariable mixed modeling was used to examine the association of risk factors with hydration status and acute kidney injury (AKI).Approximately 53% of workers were dehydrated (USG ≥1.020) pre-shift and 81% post-shift; 33% of participants had AKI on at least one workday. The odds of AKI increased 47% for each 5-degree (°F) increase in heat index.A strikingly high prevalence of dehydration and AKI exists in Florida agricultural workers.

Human exposure to endocrine disrupting chemicals (EDCs) has become common as a result of widespread application of these chemicals to the food supply, environmental contamination, and occupational exposures (Caserta et al., 2011). However, relatively little is known about the effects of EDCs such as ethylene thiourea (ETU) in developing fetuses and the lasting implications of this disruption on human development from birth through adulthood. Of highest concern are chronic, low-dose exposures among industrial and agricultural workers. Current knowledge regarding the significance of endocrine thyroid signaling on normal human development raises serious concerns about the possible deleterious effects of EDCs in the developing fetus, children, and mature adults. Occupational health nurses are critical in identifying women and families at increased risk of ETU exposure and mitigating early exposures in pregnancy.

The objective of this study was to assess work-related hygiene practices and the frequency and location of skin rashes due to cutaneous contact with crop-associated materials (e.g., pesticides) for female nursery and fernery workers in Central Florida. A cross-sectional, community-based participatory research study of 237 female nursery and fernery workers between the ages of 19 and 43 years with significant cutaneous contact with foliage crops was conducted using a self-report questionnaire and a skin rash chart assessment tool. Of the 237 farmworkers surveyed, 37.1% ( n = 88) reported a rash on at least one area of their bodies. Women who were pregnant during the study were 4.7 times more likely to report more than 30% total body surface area (TBSA) covered by rash compared with non-pregnant fernery workers ( p = .045; 95% confidence interval [CI] [1.04, 21.35]). Further research is needed to better understand the development of skin rashes among farmworkers, to generate effective prevention strategies.

The objective of this study was to determine the feasibility of field-based biomonitoring of heat-related illness (HRI) phenomena in Florida farmworkers. The authors determined feasibility through participant interviews regarding acceptability, data capture, recruitment and retention, and observed barriers and challenges to implementation.Study participants were employed in fernery operations in northeast Central Florida where ornamental ferns are grown and harvested in a seasonally high-heat environment. In this pilot, a total of 43 farmworkers participated during summers 2012 and 2013 and measurements included body core temperature, heart rate, energy expenditure, urine and blood osmolality, and self-reported HRI symptoms.Data capture was approximately 90%. Participants reported that the study methods were nonobtrusive to their work, and that they were comfortable with study measures.These results open possibilities for characterizing HRI utilizing physiologic biomonitoring in vulnerable occupational groups.

OBJECTIVE This study was designed to examine the associations between regional weather data and agricultural worksite temperatures in Florida. METHODS Florida farmworkers (n = 105) were each monitored using iButton technology paired with simultaneous data from regional weather stations. Conditional inference tree models were developed for (1) regional environmental temperatures and iButton (worksite) temperatures, and (2) regional heat index (HI) and iButton HI. RESULTS Worksite temperatures were partitioned by regional temperature at the primary node of 29.1°C. Worksite HI was partitioned at nodes of 33.0°C, 36.0°C, 37.0°C, and 40.0°C. The nodes at 33.0°C and 40.0°C mirror the National Weather Service's category entry points for "extreme caution" and "danger" regarding the risk of developing heat-related illness. CONCLUSION Regional weather data have the potential to provide estimations of worksite environmental conditions allowing employers to quickly implement strategies to protect workers.

Background Laboring in hot and humid conditions is a risk factor for heat-related illnesses. Little is known about the amount of physical activity performed in the field setting by agricultural workers, a population that is among those at highest risk for heat-related mortality in the United States. Methods We measured accelerometer-based physical activity and work activities performed in 244 Florida agricultural workers, 18 to 54 years of age, employed in the fernery, nursery, and crop operations during the summer work seasons of 2015-2017. Environmental temperature data during the participant's workdays were collected from the Florida Automated Weather Network and used to calculate wet bulb globe temperature (WBGT). Generalized linear mixed model regression was used to examine the association between WBGT on physical activity, stratified by the agricultural sector. Results Fernery workers had the highest overall volume of physical activity, spending nearly 4 hours in moderate to vigorous activity per workday. Activity over the course of the workday also differed by the agricultural sector. A reduction on average physical activity with increasing environmental temperature was observed only among crop workers. Conclusions The quantity and patterns of physical activity varied by the agricultural sector, sex, and age, indicating that interventions that aim to reduce heat-related morbidity and mortality should be tailored to specific subpopulations. Some workers did not reduce overall physical activity under dangerously hot environmental conditions, which has implications for policies protecting worker health. Future research is needed to determine how physical activity and climatic conditions impact the development of heat-related disorders in this population.

Background: Girasoles is an academic–community partnership investigating heat-related illness (HRI) among farm-workers. An unexpected outcome is health screening and intervention for participants without access to health care. Objectives: We present a case of renal failure in a farmworker, detected during data collection, to illustrate how academic–community collaboration can result in clinical benefits for study participants. Methods: Girasoles is examining physiologic responses to heat stress, associated vulnerability factors, and HRI symptoms. Data include blood pressure, fasting and non-fasting blood glucose, blood creatinine, blood urea nitrogen, and urine dipsticks. Participants with out-of-range findings are referred to local health care providers. Results: During two summers, health screenings of 192 workers resulted in 71 referrals (37%) for conditions to be rechecked and treated. One of these referrals involved chronic renal failure requiring extensive follow-up by research team members. Conclusions: The case of renal failure illustrates the value of collaborative research as a health intervention with vulnerable populations.

There is no escaping the fact that the ability to skillfully influence change is a requirement for nurse leaders. This need is intensified as the national health care system reforms and as the morphology of health care systems continues to change, especially in academic health care systems. The purpose of this article was 2-fold. The first objective was to relay the experience of the integration of nursing practice, education, and research within an academic health care system. The second was to, through this story of integration, expose the uniqueness and importance of nurse leader roles influencing innovation across a multisystem enterprise to fulfill the organization's mission.

Repealing the Affordable Care Act (ACA) has significant implications for the future of occupational health nursing practice. As changes are proposed and implemented, occupational health nurses must continue to prioritize preventive care, chronic disease management, healthy communities, environmental health, and sustainability. In particular, immigrant workers are a vulnerable population needing attention by occupational health nurses.

To examine changes in health beliefs, pesticide safety knowledge, and biomarkers of pesticide exposure in indigenous farmworkers who received enhanced pesticide safety training compared with those receiving the standard training.Farmworkers in Oregon were randomly assigned to either a promotors pesticide safety training program or a standard video-based training. Spot urine samples were analyzed for dialkyl phosphate urinary metabolites. Pre-/postintervention questionnaires were used to measure pesticide safety knowledge, health beliefs, and work practices.Baseline to follow-up improvements in total pesticide knowledge scores were higher in the promotor group than in the standard video group. Pairwise differences in mean concentrations of dialkyl phosphate metabolite levels showed declines from baseline to follow-up for both intervention groups.Results showed reductions in pesticide exposure in indigenous-language speaking farmworkers who received enhanced pesticide safety training.

While the impact of active maternal smoking during pregnancy on child health has been well investigated, the association between maternal passive smoking, or environmental tobacco smoke (ETS), or second-hand smoke, and behavioral development of offspring is less clear. This study examines the association between maternal ETS exposure during pregnancy and child behavior problems.Cross-sectional data of 646 mother-child pairs from the Jintan China Cohort Study were used in the analyses. Mother's exposure to tobacco smoking at home, the workplace, and other places during pregnancy (for the determination of maternal ETS exposure) and children's behaviors (via Child Behavior Checklist) were assessed when the children were 5-6 years old. Logistic regression models were constructed to examine associations between maternal exposure to ETS during pregnancy and internalizing and externalizing behavior problems, adjusting for potential cofounders including child sex and parental characteristics.37% of mothers reported ETS during pregnancy. Children of mothers exposed to ETS during pregnancy had higher scores for externalizing and total behavior problems, with 25% of children whose mothers were exposed to ETS compared to 16% of children of unexposed mothers. After adjusting for potential confounders, ETS exposure was associated with a higher risk of externalizing behavior problems in offspring of exposed mothers (OR=2.08, 95% confidence interval [CI] 1.27-3.43). Analysis after multiple imputations and sensitivity analysis further verified the association, but no dose-response relationship was found. ETS exposure, however, was not associated with internalizing or total behavior problems.This study suggests that maternal ETS exposure during pregnancy may impact child behavioral development, particularly externalizing behaviors.

Work is a major part of the human experience, and most individuals spend over one third of their waking hours doing a job. Considering this span of time, what we experience and encounter while working undoubtedly has significant bearing on our health. Moreover, the jobs we do typically define a larg

Occupational pesticide exposure may be hazardous to pregnant farmworkers, yet few studies have focused on the health of female farmworkers distinct from their male counterparts or on the impact of agricultural work tasks on pregnancy outcomes. In the current community-based participatory research study, researchers conducted five focus groups with female nursery and fernery workers in Central Florida to enhance knowledge of attitudes about occupational risks and pregnancy health and to gather qualitative data to help form a survey instrument. This article presents the results from questions focused on pesticide exposure and its impact on general, reproductive, pregnancy, and fetal health. Workers reported a belief that pesticide exposure could be hazardous to pregnancy health; descriptions of symptoms and health concerns believed to be related to farmwork and to pesticide exposure; and descriptions of barriers preventing them from practicing safer occupational behaviors.

In 2004, the American Association of Colleges of Nursing (AACN) adopted a position statement concerning the future of advanced practice nursing education. A target date of 2015 was articulated as the point by which master's preparation for advanced practice nurses would be replaced by doctoral level education. Seismic shifts in the realities surrounding nursing education and practice have occurred since the proposal to require a Doctor of Nursing Practice (DNP) degree for entry into advanced practice nursing was proposed. Unprecedented economic challenges have resulted in significant budget downturns for all sectors, including higher education. The consequent cutbacks, furloughs, and restructuring in educational operations of all types have placed enormous demands on faculty, staff, and students across the country. In addition, the growing incidence and earlier onset of chronic disease, a rapidly aging population, health care reform agendas, a shortage of primary care practitioners, and projected severe shortages of nursing faculty have raised fundamental questions about the capacity of nursing education to produce the numbers of advanced practice nurses needed. This article addresses the changing realities and growing concerns associated with the future of advanced practice nursing. Recommendations to ensure continuing development of advanced nursing practice that serves the interests and needs of the public now and in the future are presented within the context of a national workforce perspective.

Since their discovery, the safety of artificial sweeteners has been controversial. Artificial sweeteners provide the sweetness of sugar without the calories. As public health attention has turned to reversing the obesity epidemic in the United States, more individuals of all ages are choosing to use these products. These choices may be beneficial for those who cannot tolerate sugar in their diets (e.g., diabetics). However, scientists disagree about the relationships between sweeteners and lymphomas, leukemias, cancers of the bladder and brain, chronic fatigue syndrome, Parkinson's disease, Alzheimer's disease, multiple sclerosis, autism, and systemic lupus. Recently these substances have received increased attention due to their effects on glucose regulation. Occupational health nurses need accurate and timely information to counsel individuals regarding the use of these substances. This article provides an overview of types of artificial sweeteners, sweetener history, chemical structure, biological fate, physiological effects, published animal and human studies, and current standards and regulations.

Personal care items including lotions, perfumes, deodorants, shampoos, and cosmetics are sources of phthalate exposure. Women of childbearing age, children, and beauty salon workers are at greater risk for exposure. Occupational health nurses are in an ideal position to rally support for improved regulatory laws and for funding of evidence-based research that will reduce phthalate exposures and improve client health. Occupational health nurses must support the establishment and implementation of procedures for workplace safety inspections among susceptible populations. Information regarding reduction of overall phthalate exposure must be available for clients. Resources like phthalate-free product lists can be valuable tools in helping clients make informed decisions about alternatives to phthalates.

The China Jintan Child Cohort study began in 2004 with 1656 pre-school participants and a research focus on studying the impact of environmental exposures, such as lead, on children’s neurobehavioural outcomes. This population cohort now includes around 1000 of the original participants, who have been assessed three times over a period of 10 years. Since the original IJE cohort profile publication in 2010, participants have experienced a critical developmental transition from pre-school to school age and then adolescence. The study has also witnessed an increase in breadth and depth of data collection from the original aim of risk assessment. This cohort has added new directions to investigate the mechanisms and protective factors for the relationship between early health factors and child physical and mental health outcomes, with an emphasis on neurobehavioural consequences. The study now encompasses 11 domains, composed of repeated measures of the original variables and new domains of biomarkers, sleep, psychophysiology, neurocognition, personality, peer relationship, mindfulness and family dynamics. Depth of evaluation has increased from parent/teacher report to self/peer report and intergenerational family report. Consequently, the cohort has additional directions to include: (i) classmates of the original cohort participants for peer relationship assessment; and (ii) parental and grandparental measures to assess personality and dynamics within families. We welcome interest in our study and ask investigators to contact the corresponding author for additional information on data acquisition.

The exposure of migrant and seasonal farmworkers and their families to agricultural and residential pesticides is a continuing public health concern. Pesticide exposure research has been spurred on by the development of sensitive and reliable laboratory techniques that allow the detection of minute amounts of pesticides or pesticide metabolites. The power of research on farmworker pesticide exposure has been limited because of variability in the collection of exposure data, the predictors of exposure considered, the laboratory procedures used in analyzing the exposure, and the measurement of exposure. The Farmworker Pesticide Exposure Comparable Data Conference assembled 25 scientists from diverse disciplinary and organizational backgrounds to develop methodologic consensus in four areas of farmworker pesticide exposure research: environmental exposure assessment, biomarkers, personal and occupational predictors of exposure, and health outcomes of exposure. In this introduction to this mini-monograph, first, we present the rationale for the conference and its organization. Second, we discuss some of the important challenges in conducting farmworker pesticide research, including the definition and size of the farmworker population, problems in communication and access, and the organization of agricultural work. Third, we summarize major findings from each of the conference's four foci-environmental exposure assessment, biomonitoring, predictors of exposure, and health outcomes of exposure-as well as important laboratory and statistical analysis issues that cross-cut the four foci.

The authors conducted factor analysis on survey data from 1,779 Persian Gulf War veterans. Their purposes were to: 1) determine whether factor analysis identified a unique "Gulf War syndrome" among veterans potentially exposed to chemical warfare agents; 2) compare the findings of factor analysis with those from an epidemiologic analysis of symptom prevalence; and 3) observe the behavior of factor analysis when performed on dichotomous data. The factor analysis identified three factors, but they were not unique to any particular deployment group. A unique pattern of illness was not found for the larger group of veterans potentially exposed to chemical warfare agents; however, veterans who had witnessed the demolition of chemical warfare agents at the Khamisiyah site in Iraq had a greater prevalence of dysesthesia. An analysis of the performance of dichotomous variables in factor analysis showed that the standard criteria used to determine the number of relevant factors and the dominant variables within them may be inappropriate. While Gulf War veterans appear to suffer an increased burden of illness, there is insufficient evidence to identify a unique syndrome in this population of deployed servicemen and women. Furthermore, the results provide evidence that factor analysis may make a limited contribution in this area of research.

Few epidemiological studies have been conducted that have incorporated clinical evaluations of Gulf War veterans with unexplained health symptoms and healthy controls. We conducted a mail survey of 2022 Gulf War veterans residing in the northwest United States and clinical examinations on a subset of 443 responders who seemed to have unexplained health symptoms or were healthy. Few clinical differences were found between cases and controls. The most frequent unexplained symptoms were cognitive/psychological, but significant overlap existed with musculoskeletal and fatigue symptoms. Over half of the veterans with unexplained musculoskeletal pain met the criteria for fibromyalgia, and a significant portion of the veterans with unexplained fatigue met the criteria for chronic fatigue syndrome. Similarities were found in the clinical interpretation of unexplained illness in this population and statistical factor analysis performed by this study group and others.

The agricultural industry has some of the highest incidence rates and numbers of occupational injuries and illnesses in the United States. Injuries and illnesses in agriculture result from accidents, falls, excessive heat, repetitive motion and adverse pesticide exposure. Women working in agriculture are exposed to the same hazards and risks as their male counterparts, but can face additional adverse impacts on their reproductive health. Yet, few occupational risk assessment studies have considered the reproductive health of female farmworkers. The objective of this community-based participatory research study was to conduct a retrospective, cross-sectional survey to collect information on workplace conditions and behaviors and maternal, pregnancy and infant health outcomes among a sample of female nursery and fernery farmworkers in Central Florida. Survey results showed that nursery workers were more likely to report health symptoms during their pregnancy than fernery workers. We also observed a self-reported increased risk of respiratory illness in the first year of life for infants whose mothers worked in ferneries. Our findings confirm that agricultural work presents potential reproductive hazards for women of childbearing age.

OBJECTIVE:: To compare workplace characteristics, workplace behaviors, and the health beliefs of female farmworkers of childbearing age with actual biomarkers of exposure to organophosphate pesticides and to the fungicide mancozeb. METHODS:: Hispanic and Haitian farmworkers between the ages of 18 and 40 years working in nursery or fernery operations were recruited to participate in a cross-sectional survey, examining demographics, work practices, work-related hygiene, and pesticide exposure beliefs. Single-void (spot) urine samples were analyzed for organophosphate and ethylenethiourea metabolites. RESULTS:: Women in nurseries worried less frequently about the effects of pesticides on their health than those in fernery operations. In summary, organophosphate and ethylenethiourea levels in nursery workers were significantly higher than levels in fernery workers and the control group. CONCLUSIONS:: Results showed that perceived pesticide exposure did not correspond to actual metabolite levels within differing agricultural subpopulations. Language: en

Although agricultural workers have elevated risks of heat-related illnesses (HRI), pregnant farmworkers exposed to extreme heat face additional health risk, including poor pregnancy health and birth outcomes. Qualitative data from five focus groups with 35 female Hispanic and Haitian nursery and fernery workers provide details about the women's perceptions of HRI and pregnancy. Participants believe that heat exposure can adversely affect general, pregnancy, and fetal health, yet feel they lack control over workplace conditions and that they lack training about these specific risks. These data are being used to develop culturally appropriate educational materials emphasizing health promoting and protective behaviors during pregnancy.

Recent evidence suggests that antecedent red blood cell (RBC) transfusions increase the risk for necrotizing enterocolitis (NEC), the most common gastrointestinal emergency encountered by very-low-birthweight (VLBW) infants. The underlying mechanism for this association is unknown. Altered oxygenation of the mesenteric vasculature during RBC transfusion has been hypothesized to contribute to NEC development and was investigated in this study.Oxygenation patterns among four VLBW infants who developed transfusion-related NEC (TR-NEC) were compared to four VLBW infants with similar gestational age who were transfused but did not develop NEC (non-NEC). Cerebral and mesenteric patterns were recorded before, during, and 48 hours after RBC transfusion using near-infrared spectroscopy (NIRS) technology. Percentage change from mean baseline regional oxygen saturation values and cerebrosplanchnic oxygenation ratios were analyzed.All TR-NEC infants (24-29 weeks' gestation; 705-1080 g) demonstrated greater variation in mesenteric oxygenation patterns surrounding transfusions than non-NEC infants (27.6-30 weeks' gestation; 980-1210 g). TR-NEC infants received larger mean volumes of total blood (27.75 ± 8.77 mL/kg) than non-NEC infants (15.25 ± 0.5 mL/kg).Wide fluctuation and decreases in mesenteric oxygenation patterns are more pronounced in TR-NEC infants, especially before TR-NEC onset, compared to non-NEC infants. Greater total volume of infused blood was associated with TR-NEC in preterm infants. Using NIRS, larger prospective studies are needed to further evaluate potential risk factors for NEC in this high-risk population.
