Respirable dust and crystalline silica concentrations among workers at a brick kiln in Bhaktapur, Nepal.

Exposure to respirable dust and crystalline silica (SiO2) has been linked to chronic obstructive pulmonary disease, silicosis, cancer, heart disease, and other respiratory diseases. Relatively few studies have measured respirable dust and SiO2 concentrations among workers at brick kilns in low- and middle-income countries. The purpose of this study was to measure personal breathing zone (PBZ) respirable dust and SiO2 concentrations among workers at one brick kiln in Bhaktapur, Nepal. A cross-sectional study was conducted among 49 workers in five job categories: administration, fire master, green (unfired) brick hand molder, green brick machine molder, and top loader. PBZ air samples were collected from each worker following Methods 0600 (respirable dust) and 7500 (respirable crystalline SiO2: cristobalite, quartz, tridymite) of the U.S. National Institute for Occupational Safety and Health. Eight-hour time-weighted average (TWA) respirable dust and quartz concentrations were also calculated. SiO2 percentage was measured in one bulk sample each of wet clay, the release agent used by green brick hand molders, and top coat soil at the brick kiln. The geometric mean (GM) sample and TWA respirable dust concentrations were 0.20 (95% confidence interval [CI]: 0.16, 0.27) and 0.12 (95% CI: 0.09, 0.16) mg/m3, respectively. GM sample and TWA quartz concentrations were 15.28 (95% CI: 11.11, 21.02) and 8.60 (95% CI: 5.99, 12.34) µg/m3, respectively. Job category was significantly associated with GM sample and TWA respirable dust and quartz concentrations (all p < 0.0001). Top loaders had the highest GM sample and TWA respirable dust concentrations of 1.49 and 0.99 mg/m3, respectively. Top loaders also had the highest GM sample and TWA quartz concentrations of 173.08 and 114.39 µg/m3, respectively. Quartz percentages in bulk samples were 16%-27%. Interventions including using wet methods to reduce dust generation, administrative controls, personal protective equipment, and education and training should be implemented to reduce brick kiln worker exposures to respirable dust and SiO2.

Exercise is Medicine on Campus: A Scoping Review of Evidence 2009 to 2021 and Call to Action.

ABSTRACT: The Exercise is Medicine On Campus (EIM-OC) program began in 2009 at Chatham University by Dr. Robert Sallis, Dr. Carena Winters, and ACSM leadership. The vision of EIM-OC is "to see all campus and community members across multiple disciplines discover, share, and adopt the principles of EIM that will help change the culture of physical activity and chronic disease prevention and management campus wide." Although EIM-OC maintains close track of programmatic details, such as the number of registered and recognized institutions, a comprehensive review of EIM-OC publications has not been previously reported. The purpose of this scoping review was to 1) identify and examine all peer-reviewed evidence of EIM-OC, including scholarly articles and published abstracts of presentations; 2) analyze the key themes of EIM-OC implementation and outcomes; and 3) identify gaps in the literature. The scoping review covered all peer-reviewed publications, including scholarly articles and published abstracts, from 2009 to December 2021. In total, 9 scholarly articles and 46 published abstracts were included in this review. The articles and abstracts covered a wide range of topics, including gold level (physical activity assessment and exercise referral), silver level (physical activity education), and bronze level (physical activity awareness and promotion) activities, as well as evaluation of EIM-OC programming. Now that EIM-OC programming is firmly established, we now call on campuses and leaders to strengthen their reporting of EIM-OC outcomes at all levels: gold, silver, and bronze. Publishing research evidence will strengthen EIM-OC programming and initiatives. Specifically, we encourage publishing scholarly articles and using broad means for increasing dissemination.

Sedentary behavior and physical activity of young adult university students.

Movement and non-movement behaviors include sleep, sedentary behavior (SB) and physical activity (PA). While young adults are generally perceived as healthy, the level and relationship of SB and PA in college-age students has not been greatly explored. The purpose of this study was to objectively measure the levels of SB and PA in 18-20 year-old university students, record their self-reported extracurricular activities, and explore the relationship of all these with body mass index (BMI) and waist circumference (WC). Male (n = 48) and female (n = 46) students participated in this cross-sectional study. Hierarchical multiple regression analyses were used to examine time spent in SB, moderate to vigorous physical activity (MVPA), number of self-reported sedentary extracurricular activities, and their relation to the dependent variables of BMI and WC. In correlation analyses, SB (p < .001) and MVPA (p = .017) both were negatively associated with BMI, and "other" race or ethnicity (African American, Hispanic, mixed; p = .013) and number of self-reported sedentary extracurricular activities (p = .006) were positively associated with BMI. In the WC regression model, SB (p = .018) was negatively associated and number of self-reported sedentary extracurricular activities (p = .006) was positively associated with WC. University students may be both highly active and highly sedentary. Future researchers should consider targeting interventions to reduce SB in addition to improving PA.

Validation of Accelerometer Thresholds and Inclinometry for Measurement of Sedentary Behavior in Young Adult University Students.

Sedentary behavior (SB) is a major contributor to obesity and significant morbidity and mortality in adolescence and adulthood, yet measurement of SB is still evolving. The purpose of this study was to assess the degree of construct validity of the inclinometer function and single-axis and vector magnitude accelerometry metrics of the ActiGraph GT3X+ in objectively measuring SB and physical activity in 28 young adult university students who performed nine semi-structured activities, each for five minutes: lying, sitting, reading, seated video gaming, video watching, seated conversation, standing, stationary biking, and treadmill walking. Inclinometry and four output metrics from the ActiGraph were analyzed in comparison to direct observation by a researcher recorded each minute. For overall accuracy in measuring both SB and physical activity, all four accelerometer metrics (94.7-97.8%) outperformed the inclinometer function (70.9%). Vector magnitude accelerometry with a threshold of 150 counts per minute as the cut point for sedentary behavior was superior to other methods. While accelerometry was more accurate overall at detecting the behaviors tested, inclinometry had some advantages over accelerometry methods at detecting walking, biking, and standing. The findings support use of accelerometry as a valid objective measure of body movement, while use of inclinometry as a sole measure is not recommended. Additional research would be beneficial to improve the calibration of the inclinometer and explore ways of combining this with accelerometer data for objectively measuring SB and physical activity.

mHealth Gratitude Exercise Mindfulness App for Resiliency Among Neonatal Intensive Care Unit Staff: Three-Arm Pretest-Posttest Interventional Study.

BACKGROUND: Health care is highly complex and can be both emotionally and physically challenging. This can lead health care workers to develop compassion fatigue and burnout (BO), which can negatively affect their well-being and patient care. Higher levels of resilience can potentially prevent compassion fatigue and BO. Strategies that enhance resilience include gratitude, exercise, and mindfulness. OBJECTIVE: The purpose of this study was to determine if a 3-week daily resiliency practice, prompted via a gratitude, exercise, and mindfulness smartphone app, impacted the professional quality of life, physical activity, and happiness level of health care workers in a newborn intensive care unit setting. METHODS: In total, 65 participants from a level III newborn intensive care unit at a regional hospital in the western United States completed this study. The Professional Quality of Life Scale, Physical Activity Vital Sign, and Subjective Happiness Score instruments were used to evaluate the effects of the mobile health (mHealth) intervention. Further, 2-tailed dependent paired t tests were used to evaluate participant pre- and postintervention instrument scores. Multiple imputation was used to predict scores of participants who practiced an intervention but did not complete the 3 instruments post intervention. RESULTS: Dependent t tests using the original data showed that participants, as a whole, significantly improved in BO (t35=2.30, P=.03), secondary trauma stress (STS; t35=2.11, P=.04), and happiness (t35=-3.72, P<.001) scores. Compassion satisfaction (CS; t35=-1.94, P=.06) and exercise (t35=-1.71, P=.10) were trending toward, but did not reach, significance. Using the original data, only the gratitude intervention group experienced significant improvements (CS, BO, and happiness), likely due to the higher number of participants in this group. Analysis using imputed data showed that participants, as a whole, had significant improvements in all areas: CS (t64=-4.08, P<.001), BO (t64=3.39, P=.001), STS (t64=4.08, P<.001), exercise (t64=-3.19, P=.002), and happiness (t64=-3.99, P<.001). Looking at the intervention groups separately using imputed data, the gratitude group had significant improvements in CS, BO, STS, and happiness; the exercise group had significant improvements in STS and exercise; and the mindfulness group had significant improvements in CS and happiness. CONCLUSIONS: Phone app delivery of resilience-enhancing interventions is a potentially effective intervention model for health care workers. Potential barriers to mHealth strategies are the technical issues that can occur with this type of intervention. Additional longitudinal and experimental studies with larger sample sizes need to be completed to better evaluate this modality.

Differential Inflammatory Cytokine Elaboration in Serum from Brick Kiln Workers in Bhaktapur, Nepal.

Previous studies involving workers at brick kilns in the Kathmandu Valley of Nepal have investigated chronic exposure to hazardous levels of fine particulate matter (PM2.5) common in ambient and occupational environments. Such exposures are known to cause and/or exacerbate chronic respiratory diseases, including chronic obstructive pulmonary disease (COPD) and asthma. However, there is a paucity of data regarding the status of systemic inflammation observed in exposed workers at brick manufacturing facilities within the country. In the current study, we sought to elucidate systemic inflammatory responses by quantifying the molecular cytokine/chemokine profiles in serum from the study participants. A sample of participants were screened from a kiln in Bhaktapur, Nepal (n = 32; 53% female; mean ± standard deviation: 28.42 ± 11.47 years old) and grouped according to job category. Blood was procured from participants on-site, allowed to clot at room temperature, and centrifuged to obtain total serum. A human cytokine antibody array was used to screen the inflammatory mediators in serum samples from each of the participants. For the current study, four job categories were evaluated with n = 8 for each. Comparisons were generated between a control group of administration workers vs. fire master workers, administration workers vs. green brick hand molders, and administration workers vs. top loaders. We discovered significantly increased concentrations of eotaxin-1, eotaxin-2, GCSF, GM-CSF, IFN-γ, IL-1α, IL-1ß, IL-6, IL-8, TGF-ß1, TNF-α, and TIMP-2 in serum samples from fire master workers vs. administration workers (p < 0.05). Each of these molecules was also significantly elevated in serum from green brick hand molders compared to administration workers (p < 0.05). Further, each molecule in the inflammatory screening with the exception of TIMP-2 was significantly elevated in serum from top loaders compared to administration workers (p < 0.05). With few exceptions, the fire master workers expressed significantly more systemic inflammatory molecular abundance when compared to all other job categories. These results reveal an association between pulmonary exposure to PM2.5 and systemic inflammatory responses likely mediated by cytokine/chemokine elaboration. The additional characterization of a broader array of inflammatory molecules may provide valuable insight into the susceptibility to lung diseases among this population.

Wearable Activity Trackers That Motivate Women to Increase Physical Activity: Mixed Methods Study.

BACKGROUND: Physical inactivity is a significant public health concern, particularly among women in the United States. Wearable activity trackers (WATs) have been proposed as a potential solution to increase awareness of and engagement in physical activity (PA). However, to be effective, WATs must include features and designs that encourage daily use. OBJECTIVE: This study aims to explore the features and designs of WATs that appeal to women and determine whether devices with these attributes are effective motivators for women to be physically active. METHODS: A mixed methods study guided by the self-determination theory was conducted among 15 women. Participants trialed 3 WATs with influence in their respective accessory domains: Apple Watch for the wrist; Oura Ring for the finger; and Bellabeat Leaf Urban for multiple sites (it can be worn as a bracelet, necklace, or clip). Participants documented their daily PA levels and rated their satisfaction with each device's comfort, features, and motivational effect. Focus groups were also conducted to gather additional feedback and experiences within the a priori areas of comfort, features, and motivation. RESULTS: Behavioral Regulation in Exercise Questionnaire-2 scores indicated that most participants (14/15, 93%) were motivated at baseline (amotivation score: mean 0.13, SD 0.45), but on average, participants did not meet the national minimum PA guidelines according to the self-reported Physical Activity Vital Sign questionnaire (moderate to vigorous PA score: mean 144, SD 97.5 min/wk). Mean WAT wear time was 16.9 (SD 4.4) hours, 19.4 (SD 5.3) hours, and 20.4 (SD 4.7) hours for Apple Watch, Bellabeat Leaf Urban, and Oura Ring, respectively. During focus groups, participants reinforced their quantitative ratings and rankings of the WATs based on personal experiences. Participants shared a variety of both activity-related and non-activity-related features that they look for in a motivating device. When considering what the ideal WAT would be for a woman, participants suggested features of (1) comfort, (2) extended battery life, (3) durability, (4) immediate PA feedback, (5) intuitive PA sensing, and (6) programmability. CONCLUSIONS: This study is the first to specifically address women's experiences with and preferences for different types of WATs. Those who work with women should realize how they view WATs and the role they play in motivation to be active.

HPV Infection and Vaccination: A Question and Answer Guide for School Nurses.

School nurses frequently interact with school-age children and their parents/guardians regarding vaccinations. As a trusted source of information, the school nurse is in a unique position to share vaccine information with parents/guardians and school-age children that may dispel myths and, consequently, improve vaccination rates. Nevertheless, some parents/guardians are still reluctant to vaccinate their school-age children against Human Papilloma Virus (HPV) for a variety of reasons. Common barriers to HPV vaccination include a lack of understanding of the vaccine's purpose, concerns regarding the vaccine's safety, and insufficient recommendation from healthcare workers. However, school nurses have many duties in addition to ensuring vaccine compliance. School nurses may have difficulty remaining up-to-date on evidence-based answers to parents'/guardians' questions about HPV vaccine. Therefore, the purpose of this article is to provide school nurses with a quick reference question and answer guide to parents'/guardians' common HPV-related vaccination questions.

Successfully incorporating Writing Across the Curriculum with advanced writing in nursing.

The purpose of this article is to explain the concepts of Writing Across the Curriculum, Writing in the Disciplines, and Writing to Learn, and to describe the incorporation of advanced writing into a baccalaureate nursing program and provide suggestions for accessing resources and promoting success. The goals of incorporating Writing Across the Curriculum, Writing in the Disciplines, and Writing to Learn concepts into nursing curriculum are to assist nursing students to achieve competence in clinically relevant writing assignments; to demonstrate critical thinking and communication skills, both oral and written; to execute useful literature searches; to read and understand research reports; and to encourage the incorporation of evidence into clinical practice. With a strong and established writing foundation, nursing students will be more successful in written and oral communication during their nursing program and throughout their nursing career.

Does family communication matter? Exploring knowledge of breast cancer genetics in cancer families.

Knowledge of breast cancer genetics is critical for those at increased hereditary risk who must make decisions about breast cancer screening options. This descriptive study explored theory-based relationships among cognitive and emotional variables related to knowledge of breast cancer genetics in cancer families. Participants included first-degree relatives of women with breast cancer who had received genetic counseling and testing. Study participants themselves did not have breast cancer and had not received genetic counseling or testing. Data were collected by telephone interviews and surveys. Variables analyzed included numeracy, health literacy, cancer-related distress, age, education, and the reported amount of information shared by the participants' family members about genetic counseling. The multiple regression model explained 13.9% of variance in knowledge of breast cancer genetics (p = 0.03). Best fit of the multiple regression model included all variables except education. Reported amount of information shared was the only independently significant factor associated with knowledge (ß = 0.28, p = 0.01). Participants who reported higher levels of information shared by a family member about information learned during a genetic counseling session also demonstrated increased knowledge about breast cancer genetics.

Cost-efficient treatment for uninsured or underinsured patients with hypertension, depression, diabetes mellitus, insomnia, and gastroesophageal reflux.

PURPOSE: As the number of uninsured and underinsured patients in the United States continues to rise, savvy nurse practitioners (NPs) must balance quality of care with cost of drugs. This article reviews evidence-based treatments in light of prescribing the most cost-efficient medications. DATA SOURCES: Searches of electronic databases including MEDLINE, MEDLINEPlus, EBSCO, PubMed, CINAHL, Clinical Pharmacology, Biomedical Reference Collection--Basic, Health Source--Consumer Edition, Health Source--Nursing/Academic Edition, Ovid, and the Cochrane Library Online. CONCLUSIONS: As the role of NP continues to evolve, it is important for NPs to establish themselves as economically conscious healthcare providers, striking a delicate balance between providing quality and cost-efficient care. An NP's familiarity with cost-efficient treatment options for common diagnoses such as hypertension, depression, diabetes mellitus, insomnia, and gastroesophageal reflux disorders can help ease the economic burden uninsured and underinsured patients endure, especially with respect to prescription drugs, and improve compliance with medication regimens. IMPLICATIONS FOR PRACTICE: NPs should acquire knowledge on how to best treat uninsured or underinsured patients in the most cost-efficient manner. Knowledge of prescription drug cost is one tool an NP can use to encourage patient compliance, improving the overall health of uninsured or underinsured individuals.

Qualitative Analysis of Student Perceptions of Bachelor of Science-to-Doctor of Philosophy in Nursing Programs.

BACKGROUND: To address the shortage of Doctor of Philosophy (PhD)-prepared nursing faculty, universities in the United States offer direct-entry Bachelor of Science in Nursing (BSN)-to-PhD nursing programs. Little research has been conducted to explore students' perceptions of these programs and to formally evaluate the successes and opportunities for growth of this academic track. METHOD: Focusing on the perceptions and experiential reflection of BSN-to-PhD education, a survey with open-ended questions was distributed among voluntary participants who are current BSN-to-PhD students or recent graduates (within 5 years) from various universities in the United States. Textual data were analyzed using a qualitative descriptive approach with thematic analysis. RESULTS: This article elaborates on opportunities, challenges, and suggestions related to this educational route, as recognized by 21 participants from seven universities. CONCLUSION: The study findings may facilitate discussion among nurse educators to revise programs to be congruent with the needs of current students while paving the way for future scholars.

Parental hesitation as a factor in delayed childhood immunization.

INTRODUCTION: One reason for lower immunization rates is that some parents hesitate to have their children immunized. A hesitancy questionnaire was developed to identify reasons parents hesitate in having their children immunized. METHODS: The hesitancy questionnaire was distributed from local pediatric and family practice offices and from the area's county health department. To be eligible, participants needed to be present in the clinic with a child needing a minimum of one immunization that was at least 6 months overdue. RESULTS: When questioned why their child was overdue for immunizations, the most common response was that participants were confused about the immunization schedule and not sure when to return. Of the participants who reported having concerns regarding immunizations, the child's pain/crying/anxiety was the most commonly occurring answer. When asked where they receive the majority of childhood immunization information, participants frequently identified their health care provider as the main source of information. DISCUSSION: Health care providers may be missing opportunities to educate hesitant parents about immunizations. Parents may not have ample opportunities to discuss their immunization concerns in detail with their health care provider during regularly scheduled clinic visits. It is important for health care providers to suggest ways parents can cope with their child's pain/crying/anxiety when receiving immunizations.
