Formulations of Job Strain and Psychological Distress: A Four-year Longitudinal Study in Japan.

Background: Different job strain formulations based on the Job Demand-Control model have been developed. This study evaluated longitudinal associations between job strain and psychological distress and whether associations were influenced by six formulations of job strain, including quadrant (original and simplified), subtraction, quotient, logarithm quotient, and quartile based on quotient, in randomly selected Japanese workers. Methods: Data were from waves I and II of the Survey of Midlife in Japan (MIDJA), with a 4-year follow-up period. The study sample consisted of 412 participants working at baseline and had complete data on variables of interest. Associations between job strain at baseline and psychological distress at follow-up were assessed via multivariable linear regression, and results were expressed as ß coefficients and 95% confidence intervals including R2 and Akaike information criterion (AIC) evaluation. Results: Crude models revealed that job strain formulations explained 6.93-10.30% of variance. The AIC ranged from 1475.87 to 1489.12. After accounting for sociodemographic and behavioral factors and psychological distress at baseline, fully-adjusted models indicated significant associations between all job strain formulations at baseline and psychological distress at follow-up: original quadrant (ß: 1.16, 95% CI: 0.12, 2.21), simplified quadrant (ß: 1.01, 95% CI: 0.18, 1.85), subtraction (ß: 0.39, 95% CI: 0.09, 0.70), quotient (ß: 0.37, 95% CI: 0.08, 0.67), logarithm quotient (ß: 0.42, 95% CI: 0.12, 0.72), and quartile based on quotient (ß: 1.22, 95% CI: 0.36, 2.08). Conclusion: Six job strain formulations showed robust predictive power regarding psychological distress over 4 years among Japanese workers.

A pilot study to improve provider adherence to NAEPP guidelines.

The prevalence and morbidity of Asthma in the United States has increased since the 1991 National Asthma Education and Prevention Program (NAEPP) and updated Expert Panel Report -3 (EPR-3) guidelines in 2007 were published. To improve provider adherence to the NAEPP EPR-3 guidelines Children's Hospital of Orange County (CHOC) in California integrated the HealtheIntentSM Pediatric Asthma Registry (PAR) into the electronic medical record (EMR) in 2015. METHODS: A serial cross-sectional design was used to compare provider management of CHOC MediCal asthma patients before 2014 (N = 6606) and after 2018 (N = 6945) integration of the Registry with NAEPP guidelines into the EMR. Four provider adherence measures (Asthma Control Test [ACT], Asthma Action Plan [AAP], inhaled corticosteroids [ICS] and spacers) were evaluated using General Linear Mixed Models and Chi square. FINDINGS: In 2018, patients were more likely to receive an ACT, (OR = 14.95, 95% CI 12.67, 17.65, p < .001), AAP (OR = 12.70, 95% CI 11.10, 14.54, p < .001), ICS (OR = 1.85, 95% CI 8.52, 14.54, p < .001) and spacer (OR = 1.45, 95% CI 1.31, 1.6, p < .001) compared to those in 2014. DISCUSSION: The pilot study showed integration of the Pediatric Asthma Registry into the EMR, as a computer decision support tool that was an effective intervention to increase provider adherence to NAEPP guidelines. Ongoing monitoring and education are needed to promote and sustain provider behavioral change. Additional research to include multi-sites and decreased time between evaluation years is recommended. APPLICATION TO PRACTICE: Can be used for excellent health policy decision making as a direct impact on patient care and outcomes, by improving provider adherence to the NAEPP guidelines.

Shift Work and Sleep Disturbance in the Oil Industry.

BACKGROUND: Rotating shift work is common in high-hazard industries, despite documented associations with sleep disturbance and impairment. In the oil industry, where rotating and extended shift schedules are used to staff safety-sensitive positions, work intensification and increasing overtime rates have been broadly documented over the last few decades. Research on the impacts of these work schedules on sleep and health has been limited for this workforce. METHODS: We examined sleep duration and quality among rotating shift workers in the oil industry and explored associations between schedule characteristics, sleep, and health outcomes. We recruited hourly refinery workers from the West and Gulf Coast oil sector members of the United Steelworkers union. FINDINGS: Impaired sleep quality and short sleep durations were common and associated with health and mental health outcomes common among shift workers. Shortest sleep durations followed shift rotations. Early rise and start times were associated with shorter sleep duration and poorer sleep quality. Drowsiness and fatigue-related incidents were common. CONCLUSION/APPLICATION TO PRACTICE: We observed lower sleep duration and quality and increased overtime in 12-hour rotating shift schedules. These long workdays with early start times may reduce available hours for quality sleep; here they were associated with reduced exercise and leisure activity which correlated with good sleep. This safety-sensitive population appears severely impacted by poor sleep quality, which has broader implications for process safety management. Later start times, slower rotation, and a reconsideration of two-shift schedules are interventions to consider for improving sleep quality among rotating shift workers.

Factors associated with health-related quality of life in children with sickle cell disease.

BACKGROUND: Sickle cell disease is an inherited haematological condition with life-threatening consequences. It can affect all aspects of the lives of children with the condition, including biopsychosocial and cognitive aspects. These children tend to have a low health-related quality of life (HRQoL). AIM: To identify factors associated with HRQoL in Omani children with sickle cell disease. METHOD: The study was a secondary analysis of data from a randomised controlled trial conducted with 72 parent-and-child dyads who were recruited from two tertiary hospitals in Oman. The aim of the original study was to examine the effects of an educational programme on the knowledge and self-efficacy of parents of children with sickle cell disease. As part of that study, parents and children completed two questionnaires on HRQoL, one generic and one specific to sickle cell disease. RESULTS: Parents' knowledge of sickle cell disease, parents' self-efficacy in managing their child's symptoms, parents' age, children's age and treatment with hydroxyurea were found to affect children's HRQoL. CONCLUSION: Healthcare providers need to include biopsychosocial and cognitive aspects of HRQoL in their assessments of children with sickle cell disease. Programmes designed to enhance parents' and children's knowledge and self-efficacy, as well as measures designed to ensure that children receive treatment with hydroxyurea, are likely to improve the HRQoL of children with sickle cell disease.

Suicide Ideation and the Association of Chronic Disease among American Indians.

Objective: To explore associations of chronic disease, perceived wellness, adverse experiences, and suicide ideation among American Indians. Methods: Thirteen California health clinic registries formed the random household survey sampling frame (N=459) during the first stage of an intervention trial on wellness. Measures included sociodemographics, wellness status, health conditions, suicide ideation, cultural connectivity (speaking tribal language, participating in cultural practices, and feeling connected to the community), and history of physical, sexual, verbal abuse and neglect in childhood, adolescence, and adulthood. Chi square and Fisher exact tests examined bivariate, unadjusted relationships, while multiple logistic regression analysis examined adjusted associations. Results: Adverse experiences, specifically physical abuse and sexual abuse, were associated with obesity in childhood. Having poor cultural connectivity was significantly associated with (1) low perceptions of wellness; (2) physical abuse in childhood and adolescence; (3) sexual abuse in childhood, adolescence, and adulthood; and (4) verbal abuse and neglect in adulthood. Poor perception of wellness was also correlated with suicide ideation. Conclusions: The relationships between suicide ideation, chronic disease, connectivity, and perception of wellness among American Indians are explored in this article.

Adulthood Psychosocial Disadvantages and Risk of Hypertension in U.S. Workers: Effect Modification by Adverse Childhood Experiences.

Hypertension is a key driver of cardiovascular diseases. However, how stressors contribute to the development of hypertension remains unclear. The objective of this study was to examine prospective associations of adverse childhood experiences (ACEs) and adulthood psychosocial disadvantages (APDs) with incident hypertension. Data were from the Mid-life in the United States (MIDUS) study, a national, population-based, prospective cohort study. ACEs were examined via retrospective reports, and APDs including work stress and social isolation were assessed using survey measures. Incident hypertension was defined based on self-reported physician diagnosis. Baseline data were collected in 1995, with follow-up in 2004-2006 and 2013-2014. Cox proportional hazards regression was applied to assess prospective associations of ACEs and APDs with incident hypertension in 2568 workers free from hypertension at baseline. After adjustment for covariates, baseline APDs were associated with increased incident hypertension (aHR and 95% CI = 1.48 [1.09, 2.01]) during a 20-year follow-up, whereas ACEs showed null associations. Moreover, a moderating effect by ACEs was observed-the effect of APDs on risk of hypertension was stronger when ACEs were present (aHR and 95% CI = 1.83 [1.17, 2.86]). These findings underscore the importance of psychosocial stressors as nontraditional risk factors of cardiometabolic disorders.

Working Conditions and Wellbeing among Prison Nurses during the COVID-19 Pandemic in Comparison to Community Nurses.

The psychological health and work challenges of nurses working in prisons during the COVID-19 pandemic are understudied. We evaluated the work and wellbeing characteristics of a California prison nurse group, with a comparison to those of a community nurse group. From May to November 2020, an online survey measured psychosocial and organizational work factors, sleep habits, psychological characteristics, COVID-19 impacts, and pre-pandemic recall among 62 prison nurses and 47 community nurses. Prison nurses had significantly longer work hours (54.73 ± 14.52, p < 0.0001), higher pandemic-related work demands, and less sleep hours (5.36 ± 1.30, p < 0.0001) than community nurses. Community nurses had significantly higher pandemic-related fear levels (work infection: p = 0.0115, general: p = 0.0025) and lower perceived personal protective equipment (PPE) supply (p = 0.0103). Between pre-pandemic and pandemic periods, both groups had significantly increased night shift assignments and decreased sleep hours, but the prison group had increased work hours. Although not statistically significant, both groups had high occupational stress and prevalence of post-traumatic stress symptoms. Our results indicate that prison nurses experienced work and wellbeing challenges during the pandemic. Future research and practice ought to address nurses' workload, PPE, and psychological resources in correctional facilities and healthcare organizations.

An analysis of prenatal exposure factors and offspring health outcomes in rodents from synthesized nanoparticles.

Over the past several decades the industry involving nanotechnology has developed at a rapid pace, increasing global human exposure to synthesized nanoparticles (NPs). A consensus within toxicology on the effect of synthesized NPs to human health has yet to be reached, and little is known about the NPs developmental toxicology to organisms exposed in utero. This review aimed to identify the current state of in vivo prenatal NP toxicology literature and to provide an overview of several influential factors on offspring exposure and health outcomes. Scientific peer-reviewed literature was identified through PubMed, Web of Science, and Google Scholar database searches using combinations of keywords relevant to prenatal NP exposure. The 220 articles yielded from the database search were screened for inclusion and exclusion criteria, and 37 articles were included in the final analysis. Across selected literature, eight NP materials and eight exposure routes were identified. Pregnant murine dams were exposed to NPs throughout the entire gestational period, and some studies expanded exposure durations into preconception or postnatal periods. The average particle size across all exposure routes was 27.03 nm, although aerosolized agglomerates and cellular uptake where not accounted for. Thirty-five studies reported significant adverse effects on offspring after birth, where abnormalities of the nervous system were most commonly reported. Although current literature suggests a biological plausibility for prenatal NP toxicity, the lack of standardized methodology and diverse endpoints contribute to the continued ambiguity as to the attributable risks of individual exposure factors on health outcomes and mechanisms of cellular toxicity.

Associations of COVID-19 Related Work Stressors with Psychological Distress: Racial and Ethnic Disparities in Californian Workers.

The COVID-19 pandemic continues to exert immense societal impacts, with recent data showing inequitable distribution of consequences among racial and ethnic groups. The objective of this study was to assess associations between COVID-related work stressors and psychological distress, with special emphasis on differences by race and ethnicity. Data were from the population-based California Health Interview Survey (CHIS) 2020. Associations of individual and cumulative work stressors, including job loss, reduced work hours, and working from home, with psychological distress in 12,113 workers were examined via multivariable linear regression, and stratified analyses were conducted for racial and ethnic subgroups. After adjustment for covariates, compared to workers with no work stressors, those who experienced either one or two/more work stressors had higher psychological distress (ßs and 95% CIs were 0.80 [0.51, 1.09] and 1.98 [1.41, 2.56], respectively). Notably, experiencing cumulative (two/more) work stressors had much stronger effects on psychological distress among participants who were Black (ß and 95% CI were 3.51 [1.09, 5.93]) or racial minorities (ß and 95% CI were 3.57 [1.10, 6.05]). Occupational consequences of the COVID-19 pandemic were associated with increased psychological distress in Californian workers and inequitably distributed, with racial and ethnic minorities suffering the greatest burden.

Associations of job strain and family strain with risk of major depressive episode: A prospective cohort study in U.S. working men and women.

BACKGROUND: Studies assessing sex differences in the associations of psychosocial strain with depression have shown mixed and inconsistent results. Our objective was to examine prospective associations of job strain and family strain with risk of major depressive episode (MDE) among United States workers, as well as assess potential effect modification by sex. METHODS: Using data from the nationally representative and population-based Mid-life in the United States (MIDUS) study with a prospective cohort design and a 9-year follow-up period, the effects of job strain and family strain at baseline on risk of MDE within the 12 months prior to the follow-up assessment were examined in 1581 workers (805 men, 776 women) who were free from MDE within the 12 months prior to the baseline survey, by multivariate Poisson regression analysis. RESULTS: After adjustment for relevant covariates, there was evidence for effect modification by sex for the association between job strain and MDE but not for the association between family strain and MDE. Indeed, high job strain was prospectively associated with the risk of MDE (RR and 95% CI = 2.14 [1.14, 4.03]) in men but not in women. Moreover, high family strain was prospectively associated with a higher risk of MDE (RR and 95% CI = 1.57 [1.05, 2.37]) in the whole sample. CONCLUSION: Family strain was associated with risk of MDE regardless of the sex of a person. In contrast, high job strain may involve an increased risk of developing MDE only in men but not in women.

Vascular Function and Serum Lipids in Women with Spontaneous Preterm Delivery and Term Controls.

Background: Spontaneous preterm delivery (sPTD) is associated with a twofold increased risk of future maternal cardiovascular disease. We hypothesized that women with sPTD would demonstrate greater vascular dysfunction postpartum compared to women with term delivery. Materials and Methods: In a case-controlled, matched pilot study, we enrolled 20 women with sPTD (gestation ≤34 weeks), and 20 term control women (gestation ≥39 weeks) were matched for age (±5 years), parity, ethnicity, and route of delivery. Vascular function, serum lipids, C-reactive protein, and interleukin-6 were completed within 24-72 hours postpartum. Statistical analysis included paired t-tests based on match and mixed effects linear regression models and adjusted for potential confounders. Results: The mean age for sPTD and term controls was 33 ± 6 years and 32 ± 6 years, respectively. Women with sPTD had significantly lower augmentation index-75 (24.1% ± 16.1% vs. 39.9% ± 15.2%, p = 0.001) and central pulse pressure (29.1 ± 5.4 mmHg vs. 34.6 ± 4.7 mmHg, p = 0.004), but no difference in pulse wave velocity (5.1 ± 1.6 m/s vs. 5.6 ± 1.5 m/s, p = 0.12) compared to controls. Women with sPTD had significantly lower high-density lipoprotein cholesterol (59.4 ± 12.5 mg/dL vs. 67.6 ± 13.1 mg/dL, p = 0.035) compared to controls. Analysis of chorioamnionitis and magnesium sulfate did not alter the results. Conclusions: Women with sPTD have signs of lower smooth muscle tone in the early postpartum period compared to women with term delivery. Further research is required to understand mechanistic pathways in sPTD and future maternal cardiovascular disease risk.

Metal(loid)s in Cucurbita pepo in a Uranium Mining Impacted Area in Northwestern New Mexico, USA.

More than 500 unreclaimed mines and associated waste sites exist on the Navajo Nation reservation as a result of uranium (U) mining from the 1940s through the 1980s. For this study, the impact of U-mine waste on a common, locally grown crop food was examined. The goal of this site-specific study was to determine metal(loid) concentration levels of arsenic (As), cadmium (Cd), cesium (Cs), molybdenum (Mo), lead (Pb), thorium (Th), U, vanadium (V) and selenium (Se) in Cucurbita pepo Linnaeus (squash), irrigation water, and soil using inductively coupled plasma-mass spectrometry. The concentrations of metal(loid)s were greatest in roots > leaves > edible fruit (p < 0.05), respectively. There were significant differences between metal(loid)s in squash crop plot usage (<5 years versus >30 years) for V (p = 0.001), As (p < 0.001), U (p = 0.002), Cs (p = 0.012), Th (p = 0.040), Mo (p = 0.047), and Cd (p = 0.042). Lead and Cd crop irrigation water concentrations exceeded the United States Environmental Protection Agency (USEPA) Maximum Contaminant Levels for drinking water for those metals. Edible squash concentration levels were 0.116 mg/kg of As, 0.248 mg/kg of Pb, 0.020 mg/kg of Cd, and 0.006 mg/kg of U. Calculated human ingestion of edible squash did not exceed Provisional Tolerable Weekly Intake or Tolerable Upper Limit levels from intake based solely on squash consumption. There does not appear to be a food-ingestion risk from metal(loid)s solely from consumption of squash. Safer access and emphasis on consuming regulated water was highlighted. Food intake recommendations were provided. Continued monitoring, surveillance, and further research are recommended.

High Carbon Monoxide Levels from Charcoal Combustion Mask Acute Endothelial Dysfunction Induced by Hookah (Waterpipe) Smoking in Young Adults.

BACKGROUND: Hookah smoking is marketed to youth as a harmless alternative to cigarettes. Although cigarette smoking acutely impairs endothelial function, the effect of smoking fruit-flavored hookah tobacco is unknown. Because charcoal traditionally is used to heat the hookah tobacco in the waterpipe, hookah smoke delivers tobacco toxicants and nicotine plus charcoal combustion products: not only carbon-rich nanoparticles, oxidants that may destroy nitric oxide and impair endothelial function, but also large amounts of carbon monoxide (CO), a putative vasodilator molecule. METHODS: To test the acute effect of hookah smoking on endothelial function, in young adult hookah smokers (n=30, age 26±1 years, mean±SE), we measured plasma nicotine, exhaled CO, and brachial artery flow-mediated dilation (FMD) before and after charcoal-heated hookah smoking. To remove the effect of charcoal combustion, the same measurements were performed when the same flavored hookah tobacco product was heated electrically (n=20). As a positive internal control, we studied age-matched cigarette smokers (n=15) who smoked 1 cigarette. To isolate the effect of the CO boost on FMD, hookah smokers (n=8) inhaled a 0.1% CO gas mixture to approximate their CO boost achieved with charcoal-heated hookah smoking. RESULTS: Nicotine levels increased similarly with all types of smoking, whereas exhaled CO increased 9- to 10-fold more after charcoal-heated hookah than after either electrically heated hookah or cigarette smoking. FMD did not decrease after smoking charcoal-heated hookah but instead increased by +43±7% ( P<0.001). In contrast, FMD decreased by -27±4% ( P<0.001) after smoking electrically heated hookah, comparable to the decrease after cigarette smoking. FMD increased markedly by 138±71% ( P<0.001) after breathing CO gas, 2.8 times more than the increase induced in the same subjects after smoking charcoal-heated hookah ( P<0.001), despite comparable increases in exhaled CO (24±1 versus 28±3 ppm, hookah versus CO). CONCLUSIONS: Smoking hookah tobacco, similar to cigarette tobacco, acutely impairs endothelial function. With traditional charcoal-heated hookah smoking, the acute endothelial dysfunction is masked by high levels of carbon monoxide, a potent vasodilator molecule generated by charcoal combustion. With respect to large-artery endothelial function, smoking hookah is not harmless. CLINICAL TRIAL REGISTRATION: URL: https://www.clinicaltrials.gov . Unique identifiers: NCT03616002 and NCT03067701.

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

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.

Acute Effect of Hookah Smoking on Arterial Stiffness and Wave Reflections in Adults Aged 18 to 34 Years of Age.

Hookah (waterpipe) smoking is rapidly increasing in popularity worldwide. Despite being heavily advertised in the media as a healthier alternative to cigarettes, the toxicology of hookah smoke suggest otherwise. Cigarette smoking unequivocally causes an acute increase in arterial stiffness, but whether hookah does the same is unknown. In 48 young healthy habitual hookah but not cigarette smokers, we measured heart rate, peripheral and central blood pressure, carotid-femoral pulse wave velocity (measure of arterial stiffness), aortic augmentation index (measure of wave reflection), plasma nicotine, and exhaled carbon monoxide before and after ad lib hookah smoking. Hookah smoking increased heart rate by +16 ± 1 beats/min and mean brachial arterial pressure by +6 ± 1 mm Hg (both p <0.05, mean ± SE). Most importantly, it increased carotid-femoral pulse wave velocity and aortic augmentation index by +0.66 ± 0.09 m/s-1 and +8.76 ± 3.99%, respectively (p <0.05, mean ± SE), denoting increased acute arterial stiffness. These vascular effects were accompanied by increases in plasma nicotine concentration (+5.8 ± 1.2 ng/ml, p <0.05) and expired carbon monoxide (+25.44 ± 1.68 ppm, p <0.05). All these parameters were unchanged during time-control studies (n = 14). Thus, in contrast to effective media marketing of hookah as a safer alternative to cigarettes, the present study shows for the first time that in young adult hookah smokers, a single hookah smoking session causes an acute increase in arterial stiffness of comparable magnitude to what has been previously reported for cigarettes. Further research is warranted to determine whether habitual hookah smoking accelerates the age-dependent development of hypertension and its cardiovascular complications.

Association of Spontaneous Preterm Delivery and Future Maternal Cardiovascular Disease.

Cardiovascular disease (CVD) risk factors are well established. However, little is known about a woman's cardiovascular response to pregnancy, which appears to be an early marker of future maternal CVD risk. Spontaneous preterm delivery (sPTD) has been associated with a ≤3-fold increased risk of maternal CVD death later in life compared with having a term delivery. This review focuses on 3 key areas to critically assess the association of sPTD and future maternal CVD risk: (1) CVD risk factors, (2) inflammatory biomarkers of interest, and (3) specific forms of vascular dysfunction, such as endothelial function and arterial stiffness, and mechanisms by which each may be linked to sPTD. The association of sPTD with subsequent future maternal CVD risk suggests that a woman's abnormal response to pregnancy may serve as her first physiological stress test. These findings suggest that future research is needed to understand why women with sPTD may be at risk for CVD to implement effective interventions earlier in a woman's life.

Job satisfaction, work environment and successful ageing: Determinants of delaying retirement among acute care nurses.

AIM: To determine the relationships between job satisfaction, work environment and successful ageing and how these factors relate to Registered Nurses' intent to retire. BACKGROUND: Although little studied, retention of older nurses by delaying early retirement, before age 65, is an important topic for research. Qualitative and quantitative studies have indicated that job satisfaction work environment and successful ageing are key motivators in acute care Registered Nurses retention and/or delaying retirement. This study was designed to provide information to administrators and policy makers about retaining older, experienced RNs longer and more productively. DESIGN: This was a correlational, descriptive, cross-sectional study. METHODS: An online survey of acute care Registered Nurses (N = 2,789) aged 40 years or older working in Florida was conducted from September - October 2013. Participants completed items related to job satisfaction, work environment, successful ageing and individual characteristics. Hypotheses derived from the modified Ellenbecker's Job Retention Model were tested using regression analysis. RESULTS: Job satisfaction scores were high. Highest satisfaction was with scheduling issues and co-workers; lowest with advancement opportunities. Successful ageing scores were also high with 81% reporting excellent or good health. Work environment explained 55% of the variance in job satisfaction. Years to retirement were significantly associated with successful ageing (p < .001), age (p < .001) and income (p < .010). CONCLUSIONS: This study provides quantitative evidence that environment and successful ageing are important areas that have an impact on job satisfaction and delay of retirement in older nurses and further studies in these areas are warranted to expand on this knowledge.

A Preliminary Community-Based Occupational Health Survey of Black Hair Salon Workers in South Los Angeles.

Black hair-salon workers face serious health hazards from the product they use on clients and other health hazards at their work. Currently there is a significant research gap in understanding the prevalence of workplace related exposures and health outcomes. The primary objective of this study was to gather preliminary data on workplace exposures and health outcomes of hair care workers in South Los Angeles. We conducted 22 surveys of salon workers at 16 salons. The results suggest the need for proper health and safety training within the salon worker community, specifically around chemical hair services. The results also suggest ergonomic workstation assessments and recommendations would be beneficial to reduce musculoskeletal disorders. Willingness of stylists to learn more about workplace hazards and how to mitigate their risks was high. Our findings indicate the need for a larger community based participatory research study on the workplace exposures of Black salon workers.

Uranium and Associated Heavy Metals in Ovis aries in a Mining Impacted Area in Northwestern New Mexico.

The objective of this study was to determine uranium (U) and other heavy metal (HM) concentrations (As, Cd, Pb, Mo, and Se) in tissue samples collected from sheep (Ovis aries), the primary meat staple on the Navajo reservation in northwestern New Mexico. The study setting was a prime target of U mining, where more than 1100 unreclaimed abandoned U mines and structures remain. The forage and water sources for the sheep in this study were located within 3.2 km of abandoned U mines and structures. Tissue samples from sheep (n = 3), their local forage grasses (n = 24), soil (n = 24), and drinking water (n = 14) sources were collected. The samples were analyzed using Inductively Coupled Plasma-Mass Spectrometry. Results: In general, HMs concentrated more in the roots of forage compared to the above ground parts. The sheep forage samples fell below the National Research Council maximum tolerable concentration (5 mg/kg). The bioaccumulation factor ratio was >1 in several forage samples, ranging from 1.12 to 16.86 for Mo, Cd, and Se. The study findings showed that the concentrations of HMs were greatest in the liver and kidneys. Of the calculated human intake, Se Reference Dietary Intake and Mo Recommended Dietary Allowance were exceeded, but the tolerable upper limits for both were not exceeded. Food intake recommendations informed by research are needed for individuals especially those that may be more sensitive to HMs. Further study with larger sample sizes is needed to explore other impacted communities across the reservation.

Young adult cancer survivors and work: a systematic review.

CONTEXT: Sixty-three percent of cancer survivors continue to work, or return to work after treatment. Among this population, work ability and challenges encountered in the workplace by young adult cancer survivors have not been well established. PURPOSE: The purposes of the study are to describe what is currently known about work-related issues for young adult cancer survivors diagnosed between ages 15 and 39, to identify gaps in the research literature, and to suggest interventions or improvements in work processes and occupational settings. METHODS: A narrative review of articles using PubMed, CINAHL, and PsychInfo was conducted without date limitations. Search phrases included young adult cancer survivors, long-term cancer survivors, young adults affected by cancer, further combined with key terms employment, work, and occupationally active. Inclusion criteria for publications were young adult cancer survivors initially diagnosed between the ages of 15 and 39, data about work or employment was presented, and articles written in English. RESULTS: Twenty-three publications met the inclusion criteria. Work-related issues included the potential for reduced work productivity from cancer-changed physical and cognitive functional ability that affected income, and resulted in distress. Coping style, support systems, and changing perspectives about work and life in general were also influential on career decisions among young adult cancer survivors. CONCLUSIONS: More research is needed to study interventions to better manage health changes in young adult cancer survivors within the context of the workplace. Since financial hardship has been shown to be especially high among young cancer survivors, employment is essential to ensure payment of cancer-associated costs and continued medical care. IMPLICATIONS FOR CANCER SURVIVORS: While young adult cancer survivors may initially grapple with cancer-related physical and psychosocial changes that impact work productivity or influence choice of occupation, employment appears to enhance overall quality of life.
