Sixteen mountain rescuers walked on a treadmill at 3.6 km/h for 5 min in each combination of three slopes (1%, 10%, 20%) and five backpack loads (0%, 10%, 20%, 30%, and 40% body weight). Relative heart rate (%HRmax), relative oxygen consumption (%VO2max), and rating of perceived exertion (RPE, Borg 1-10 scale) were compared across conditions using two-way ANOVA. Significant differences in %VO2max, %HRmax, and RPE across slopes and loads were found where burden increased directly with slope and load (main effect of slope, p < 0.001 for all; main effect of load, p < 0.001 for all). Additionally, significant slope by load interactions were found for all parameters, indicating an additive effect (p < 0.001 for all). Mountain rescuers should consider the physiological interaction between slope and load when determining safe occupational walking capacity.

Many factors contribute to the degree of exposure experienced in this setting. The study objective was to characterize the impact of workplace conditions, anthropometric variability, and task orientation on exposure for a simulated routine operations task. Methods: A chemical exposure laboratory simulation study was designed to evaluate the dependent variable of chemical exposure level in the breathing zone for methane and sulfur hexafluoride. The independent variables were (i) posture of the worker, (ii) worker anthropometry, (iii) process configuration, and (iv) gas density. Results: Pipe height was a significant predictor of gas concentration measured in the breathing zone when located in a position that encouraged the gas to enter the breathing zone of the worker. Worker anthropometry had a major impact; tall worker's (male) chemical concentrations exceeded those of the short worker (female) for methane simulations but the opposite resulted for sulfur hexafluoride. Also, worker posture had a significant impact on gas exposure where nonneutral postures were found to have higher levels of chemical concentration. Conclusions: The study findings indicate that the breathing zone location is altered by posture and worker height, which changes the exposures relative to the emission source depending on the gas density of the chemicals that are present. As a result, qualitative risk assessment cannot be performed accurately without accounting for these factors. Practically, controls may need to account for worker size differences and posture adaptations.

Little is known about personality trait differences between medical career and specialty choices after graduating from medical school when actually practicing different medical specialties. Moreover, whether personality traits contribute to important career choices such as choosing to work in the private or public sector or with clinical patient contact, as well as change of specialty, have remained largely unexplored. In a nationally representative sample of Finnish physicians (N = 2837) we examined how personality traits are associated with medical career choices after graduating from medical school, in terms of employment sector, patient contact, medical specialty and change of specialty. Methods: Personality was assessed using the shortened version of the Big Five Inventory (S-BFI). An analysis of covariance with posthoc tests for pairwise comparisons was conducted, adjusted for gender and age with confounders (employment sector, clinical patient contact and medical specialty). Results: Higher openness was associated with working in the private sector, specializing in psychiatry, changing specialty and not practicing with patients. Lower openness was associated with a high amount of patient contact and specializing in general practice as well as ophthalmology and otorhinolaryngology. Higher conscientiousness was associated with a high amount of patient contact and specializing in surgery and other internal medicine specialties. Lower conscientiousness was associated with specializing in psychiatry and hospital service specialties. Higher agreeableness was associated with working in the private sector and specializing in general practice and occupational health. Lower agreeableness and neuroticism were associated with specializing in surgery. Higher extraversion was associated with specializing in pediatrics and change of specialty. Lower extraversion was associated with not practicing with patients. Conclusions: The results showed distinctive personality traits to be associated with physicians' career and specialty choices after medical school independent of known confounding factors. Openness was the most consistent personality trait associated with physicians' career choices in terms of employment sector, amount of clinical patient contact, specialty choice and change of specialty. Personality-conscious medical career counseling and career guidance during and after medical education might enhance the person-job fit among physicians.

TY - Abstract or Summary AU - Lim CS AU - Ma Q AB - Fibrogenic carbon nanotubes (CNTs) induce the polarization of M1 and M2 macrophages in mouse lungs. Polarization of the macrophages differentiates the production of proinflammatory and pro-resolving lipid mediators (LMs) to mediate acute inflammation and its resolution in a time-dependent manner. In the present study, we examined the molecular mechanism by which multi-walled CNTs (MWCNTs) induce M1 polarization in vitro, with focus on induction of arachidonate 5-lipoxygenase (ALOX5), which is required to produce proinflammatory LMs, such as leukotriene B4 (LTB4). Treatment of J774A.1 macrophages with MWCNTs at a concentration of 2.5 µg/mL increased the expression of ALOX5 mRNA by 2.0-fold at 1-day and 2.5-fold at 3-day post-exposure. At a concentration of 10 µg/mL, MWCNTs increased the ALOX5 mRNA expression by 3.5-fold at 1-day and 5.0-fold at 3-day post-exposure. Immunoblotting shows that MWCNTs significantly increased the ALOX5 protein expression in macrophages. Luciferase reporter assays with the mouse ALOX5 promoter of 2 kilobase upstream of translation start codon demonstrate that the ALOX5 promoter activity increased more than 5-fold over background. This activity was significantly elevated following 5'-deletion analyses of ALOX5 promoter and further enhanced by MWCNT treatment, implicating a transcriptional mechanism in the induction of ALOX5. MWCNTs preferentially induced the expression of CD68, a cell surface marker of M1, by 2.5-fold and induction was persistently high to 3-day post-exposure. Moreover, both the expression and activity of the inducible nitric oxide synthase, an intracellular marker of M1 macrophages, were increased by MWCNTs, indicating induction of M1 polarization. Consistent with this notion, MWCNTs increased the capacity of the macrophages to produce proinflammatory cytokines, such as tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta), and proinflammatory LMs, such as LTB4 and prostaglandin E2 (PGE2), as measured by enzyme-linked immunosorbent assays. Taken together, these results support that persistent exposure to MWCNTs polarizes macrophages to M1 cells with induction of ALOX5 and elevated production of proinflammatory LMs to boost the acute inflammatory response to fibrogenic nanoparticles.

This review evaluates the potential for environmental transport and bioavailability of the active chemical to humans. Recent Findings: Bovine somatostatin is detectable in milk; however, there is no evidence that the protein persists in the environment nor that it is active in humans. In contrast, steroids are transported through milk and meat to humans where they may exert biological activity. Furthermore, environmental matrices such as raw water and dust may also allow for the environmental transport and bioavailability of steroids to humans. Summary: Endogenous and exogenous steroids can be found in the meat, milk, and waste materials produced by cattle. While the concentrations may be low, exposure to these matrices, most notably dairy products made with whole milk, can be a source of exogenous steroids to humans.

TY - Journal Article AU - Asfaw A AB - A growing literature has pointed out disparities in teleworking among different racial and ethnic (hereafter racial) workers. This study estimated racial disparities in teleworking due to the COVID-19 pandemic and the extent to which these disparities were mediated by four-year college education and occupation in the United States. The data source for this study was the Current Population Survey, May 2020 through July 2021. The results showed that in the reduced model, the odds for Black and Hispanic workers to telework were 35% and 55% lower, respectively, and for Asian workers 44% higher than for White workers, controlling for covariates. When four-year college education and occupation were included as mediator variables in the model, the odds for Black and Hispanic workers to telework were reduced to 7% and 16%, respectively. Overall, disparities in four-year college education and occupation explained 83% and 78% of the variation in the odds of teleworking for Black and Hispanic workers, respectively. Between the mediators, occupation explained more than 60% of the total effect. The results of this study could not rule out the possibility of racial discrimination in teleworking. Ultimately, reducing racial disparities in four-year college education and in different occupations might be a long-term solution for reducing racial disparities in teleworking.

We used data from the cross-sectional National Health and Nutrition Examination Surveys (NHANES) to assess the relationship between saturated fatty acid (SFA) intake and lung function in the general US adult population. Adults in NHANES (2007-2012) with pre-bronchodilator spirometry measurements and dietary SFA intake were included. Primary outcomes were lung function including forced expiratory volume in one second (FEV1), FEV1, forced vital capacity (FVC), FEV1/FVC ratio, percent predicted FEV1 and percent predicted FVC. Multivariable regression models in the general population as well as those with spirometry-defined airflow obstruction were used to assess the relationship between lung function measurements and dietary SFA intake after adjustment for confounders. 11,180 eligible participants were included in this study. Univariate analysis revealed a statistically significant positive association between total SFA intake and lung function outcomes; however, these relationships were attenuated after adjustment for covariates. A secondary analysis of individuals with spirometry-defined airflow obstruction (FEV1/FVC < 0.7) revealed that a lower intake of SFA was associated with reduced FEV1 (beta = -126.4, p = 0.04 for quartile 1 vs. quartile 4), FVC (beta = -165.8. p = 0.01 for quartile 1 vs. quartile 4), and percent predicted FVC (beta = -3.3. p = 0.04 for quartile 1 vs. quartile 4), after adjustment for relevant confounders. No associations were observed for the FEV1/FVC ratio and percent predicted FEV1. It is possible that characteristics such as food source and fatty acid chain length may influence associations between saturated fatty acid intake and health outcomes.

The purpose of this report is to provide information since the last climate change review with a focus on asthmatic disease. PubMed and Internet searches for topics included climate and weather change, air pollution, particulates, greenhouse gasses, traffic, insect habitat, and mitigation in addition to references contributed by the individual authors. Changes in patterns of outdoor aeroallergens caused by increasing temperatures and amounts of carbon dioxide in the atmosphere are major factors linked to increased duration of pollen seasons, increased pollen production, and possibly increased allergenicity of pollen. Indoor air pollution threats anticipated from climate changes include microbial and mold growth secondary to flooding, resulting in displacement of persons and need for respiratory protection of exposed workers. Air pollution from indoor burning of mosquito repellants is a potential anticipatory result of an increase in habitat regions. Air pollution from fossil fuel burning and traffic-related emissions can alter respiratory defense mechanisms and work synergistically with specific allergens to enhance immunogenicity to worsen asthma in susceptible subjects. Community efforts can significantly reduce air pollution, thereby reducing greenhouse gas emission and improving air quality. The allergist's approach to weather pattern changes should be integrated and anticipatory to protect at-risk patients.

Menstruation is implicated as a possible route of elimination for PFASs in women. The overall purpose of this study was to examine menstrual cycle characteristics as determinants of plasma PFAS concentrations in women. Methods: Our study sample consisted of 1977 pregnant women from the Norwegian Mother and Child Cohort (MoBa) study. The women were asked about menstrual cycle regularity in the year before the pregnancy and typical menstrual cycle length as well as other demographic and reproductive characteristics in a questionnaire completed during the pregnancy. Blood samples were collected around 17-18 weeks gestation and PFAS concentrations were measured in plasma. We examined the association between menstrual cycle characteristics and seven PFASs (perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), perfluorodecanoic acid (PFDA), perfluoroundecanoic acid (PFUnDA), perfluorohexane sulfonate (PFHxS), perfluoroheptane sulfonate (PFHpS), and perfluorooctane sulfonate (PFOS)) using multiple linear regression, adjusted for age, pre-pregnancy body mass index, smoking, education, income, parity, oral contraceptive (OC) use, inter-pregnancy interval, and breastfeeding duration. Results: Irregular cycles were not associated with PFAS concentrations. Overall, we found no evidence of associations between menstrual cycle length and PFAS concentrations. In subgroup analyses we found some evidence, among parous women, of decreased PFHpS and PFOS with short menstrual cycles; we also found, among recent OC users (in the 12 months before the questionnaire) increased PFNA and PFUnDA with long cycle length. Limitations of our study include misclassification of menstrual cycle characteristics, small sample sizes in the sub-group analyses, and a lack of information on duration and volume of menses. Conclusions: In the entire study sample, we found little evidence of menstrual cycle characteristics as determinants of PFAS concentrations. However, we observed some associations between cycle length and PFAS concentrations with some select PFAS compounds in subgroup analyses.

TY - Abstract or Summary AU - Marshall A AU - Symanski, Elaine AU - Whitworth K AB - Purpose: No studies of unconventional gas development (UGD) and preterm birth (PTB) have considered timing of UGD-activity during potentially sensitive windows of exposure nor potential differences in risk by UGD drilling phase. Methods: We conducted a case-control study nested within the cohort of women with singleton births in the expansive 24-county Barnett Shale area in North Texas, between November 30, 2010-November 29, 2012. All PTB cases during this period were included (n=13,328). We selected five controls per case, individually-matched on age and race/ethnicity. We truncated each control's time-at-risk according to the gestational age achieved by the matched case. We explored two UGD-activity metrics: 1) inverse distance-weighted (IDW) sum of wells in the completion phase ≤½ mile of the maternal residence at birth; and 2) IDW sum of gas produced ≤½ mile of the residence. Metrics were categorized as: zero wells ≤½ mile (ref), 1st, 2nd, and 3rd tertiles of UGD-activity. We considered both trimester- and gestation-specific UGD-activity. Conditional logistic regression was used to examine associations. Results: We found similarly increased odds of PTB in the 3rd tertiles of the UGD completion- [odds ratio (OR) 1.19, 95% confidence interval (CI) 1.05-1.35] and production- (1.15, 1.04-1.26) metrics for total gestation. Increased odds or PTB were observed in the 3rd tertiles of the UGD completion-metric for trimesters one (1.18, 1.01-1.38) and two (1.18, 1.01-1.39), but not trimester three. Increased odds of PTB were associated with production in all three trimesters, though the magnitude of the association was slightly attenuated in the 3rd trimester (3rd tertile OR's: trimester one 1.18, 1.07-1.30; trimester two 1.17, 1.06-1.29; trimester three 1.12, 1.01-1.23). Conclusion: Our results suggest an association between maternal residential proximity to UGD-activity and PTB. Though associations were similar by drilling phase, they were slightly stronger in the first two trimesters of pregnancy.

OBJECTIVE: Evaluate the effect of a sedentary behavior intervention on multiple dimensions of workplace health. METHODS:24 participants with chronic low back pain and desk jobs were randomized to either a sedentary behavior reduction intervention group or control. Outcomes included a modified Global Physical Activity Questionnaire (GPAQ), the Stanford Presenteeism Scale (SPS), Profile of Mood States (POMS), Health and Work Questionnaire (HWQ), SF-36 Health Survey (SF-36), and Pittsburgh Sleep Quality Index (PSQI). Six-month changes in outcomes were compared across intervention groups using ANCOVA regression, adjusting for baseline values. Cohen's d effect sizes were calculated for outcomes to explain the magnitude of group differences. RESULTS: The intervention group reported 1.5 hours/day less sitting time (p < 0.001) compared to controls at 6 months. SF-36 subscales of energy/fatigue, social functioning, and pain improved, and sleep disturbance was reduced among intervention participants. Productivity, concentration, and presenteeism were unchanged. CONCLUSIONS: A sedentary behavior reduction intervention may improve well-being and workplace health without impacting productivity and concentration in desk workers with chronic low back pain.

IL-6 has been shown to be involved in the pathogenesis of ICD; however, the involvement of the IL-22/IL-22Ra axis and its relation to IL-6 in the inflammatory response following irritant exposure are unknown. Using a chemical model of ICD, it was observed that mice with a keratinocyte-specific knockout of IL-6Ra (IL-6Radeltaker) presented with increased inflammation and IL-22Ra and IL-22 protein expression relative to WT following irritant exposure, indicating that IL-6Ra deficiency in epidermal keratinocytes leads to the upregulation of IL-22Ra and its ligand during ICD. Furthermore, it was shown that IL-6 negatively regulates the expression of IL-22Ra on epidermal keratinocytes. This effect is functional as the effects of IL-22 on keratinocyte proliferation and differentiation were markedly reduced when keratinocytes were pretreated with IL-6 prior to IL-22 treatment. These results show that IL-6 modulates the IL-22/IL-22Ra axis in the skin and suggest that this occurrence may be associated with the increased epidermal hyperplasia and exacerbated inflammatory response observed in IL-6Radeltaker mice during ICD.

Design: Case study. Methods: Data were collected in Liberia February-June 2019. Direct observation, semi-structured interviews and photographs were used to investigate how nurse practice is supported. Field notes, transcripts and photographs were coded using both directed and conventional content analysis. Reports were then generated by code to triangulate the data. Results: Thirty-seven nurses at 12 health facilities participated. The intellectual capital supporting inpatient and outpatient nurse practice differs in important ways. Inpatient nurse practice is more likely to be supported by facility-based protocols and trainings, whereas outpatient nurse practice is more likely to be supported by external protocols and trainings, often developed by the Liberian government or non-governmental organizations. This can lead to uneven provision of inpatient protocols and trainings, often favouring private facilities. Similarly, inpatient nurses rely primarily on other nurses at their facilities for clinical support while outpatient nurses often have external professional relationships that provided them with clinical guidance. Conclusion: Much has been accomplished to enable outpatient nurses to provide the primary- and secondary-care target services in the Essential Package of Health Services. However, as the Liberian government and its partners continue to work towards providing certain tertiary care services, developing analogous protocols, trainings and clinical mentorship networks for inpatient nurses will likely be fruitful, and will decrease the burden on individual facilities. Impact: Nurses are often expected to meet new service provision targets in post-emergency states. Further research into how best to support nurses as they work to meet those targets has the potential to strengthen health systems.

RESULTS: Although there was no change in total computer use in response to the hurricane (β 0.25), active computer use significantly declined (β -0.90). All measured computer use behaviors returned to baseline prior to the complete return to the physical workspace. CONCLUSION: Despite a transient period of reduced activity during closure of the workplace building, productivity returned to normal prior to the employees' return to a commercial workspace. The ability to work remotely may improve resiliency of employees to perform workplace tasks during events causing workplace displacement.

TY - Journal Article AU - Beschorner KE AU - Griffin SC AU - Hemler SL AB - Background: Shoe wear has been associated with increased slips and falls in the workplace. People wear down shoe tread at different rates; therefore, individualized shoe replacement timelines could improve resource targeting for organizations that use time as a basis for shoe replacement. Previous work has found that the shoe-floor kinetics, such as the friction requirements of walking, correlate with shoe wear rate. The use of easily measured metrics such as cadence, step length, or preferred walking speed to predict wear has not yet been investigated despite their relationship with friction requirements. Purpose: This study seeks to determine the association between shoe wear rate and gait spatiotemporal characteristics. Methods: Thirteen participants completed a longitudinal shoe wear study that consisted of a gait assessment followed by prolonged shoe wear in two pairs of slip-resistant shoes. The gait assessment was comprised of dry level-ground walking trials; kinematic and kinetic data were collected through optical motion capture and force plates. The participants' mean cadence, step length, and preferred walking speed were calculated. The participants then wore their shoes at work; the shoe wear rate was determined by measuring the periodic volumetric tread loss during this wear-at-work portion of the study. Results Three linear regression models found no significant association between the chosen gait metrics and the shoe wear rate. Conclusions: The lack of an association between the spatiotemporal gait characteristics and shoe wear rate indicates that these factors may not explain the differences in wear rate between participants. This negative finding suggests that other measures such as the required coefficient of friction are better for individualizing footwear replacement guidelines.

Forty women (50% White; age 18-40 years) participated in the study; 20 completed the task during the luteal phase and 20 during the follicular phase. Psychosocial stress was induced with the Trier Social Stress Test (TSST). On the day before the TSST, participants learned two lists of word pairs to 100% criterion. The next day, participants recalled one list after the control condition and the other after the TSST. Women in the follicular phase, but not the luteal phase, demonstrated a significant cortisol response to the TSST. There was a stress-induced decrease in emotional retrieval following the TSST, but this effect was not modified by menstrual phase. However, regression and correlational analyses showed that individual differences in stress-induced cortisol levels were associated with impaired emotional retrieval in the follicular phase only. The present findings indicate that cortisol responsivity and the impairing effects of cortisol on emotional memory are lower when levels of estradiol and progesterone are high compared to when levels are low.

Cigarette smoke exposure is a major cause of chronic obstructive pulmonary disease. Cadmium is a leading toxic component of cigarette smoke. Cadmium and zinc are highly related metals. Whereas, zinc is an essential metal required for normal health, cadmium is highly toxic. Zrt- and Irt-like protein 8 (ZIP8) is an avid transporter of both zinc and c ...

AU - Wyatt TA AU - Zweier JL AB - Cigarette smoke exposure is a major cause of chronic obstructive pulmonary disease. Cadmium is a leading toxic component of cigarette smoke. Cadmium and zinc are highly related metals. Whereas, zinc is an essential metal required for normal health, cadmium is highly toxic. Zrt- and Irt-like protein 8 (ZIP8) is an avid transporter of both zinc and cadmium into cells and is abundantly expressed in the lung of smokers compared to nonsmokers. Our objective was to determine whether disturbed zinc homeostasis through diet or the zinc transporter ZIP8 increase susceptibility to lung damage following prolonged cigarette smoke exposure. Methods: Cigarette smoke exposure was evaluated in the lungs of mice subject to insufficient and sufficient zinc intakes, in transgenic ZIP8 overexpressing mice, and a novel myeloid-specific ZIP8 knockout strain. Results: Moderate depletion of zinc intakes in adult mice resulted in a significant increase in lung cadmium burden and permanent lung tissue loss following prolonged smoke exposure. Overexpression of ZIP8 resulted in increased lung cadmium burden and more extensive lung damage, whereas cigarette smoke exposure in ZIP8 knockout mice resulted in increased lung tissue loss without a change in lung cadmium content, but a decrease in zinc. Conclusions: Overall, findings were consistent with past human studies. Imbalance in Zn homeostasis increases susceptibility to permanent lung injury following prolonged cigarette smoke exposure. Based on animal studies, both increased and decreased ZIP8 expression enhanced irreversible tissue damage in response to prolonged tobacco smoke exposure. We believe these findings represent an important advancement in our understanding of how imbalance in zinc homeostasis and cadmium exposure via tobacco smoke may increase susceptibility to smoking-induced lung disease.

TY - Journal Article AU - Qi C AU - Wang C AB - Copper-based preservatives consisting of micronized and nanoscale copper particles have been widely used in applications for wood protection. The widespread use of these preservatives along with the potential release of copper-containing nanoparticles (Cu NPs) during the life cycle of treated wood, has raised concerns over the impacts on the environment and occupational exposure. Along with assessing the potential hazards of these materials, a critical step is determining the chemical and morphological characteristics of the copper species released from copper-treated wood. Therefore, a combination of scanning transmission electron microscopy (STEM) and electron energy-loss spectroscopy (EELS) was utilized to characterize and differentiate the released copper-containing particles based on their structures, sizing, and chemical properties. Airborne wood dust samples were collected during the abrasion and sawing of micronized copper (MC) treated wood in a laboratory testing system. Based on the signature Cu L2,3 edge of EEL spectra, three different copper species (i.e., basic copper carbonate, copper, and copper-wood complex) were identified as major components of the embedded particles in wood dust. In addition, two types of individual Cu NPs consisting of basic copper carbonate and copper were identified. The variation of morphologies and chemical properties of copper-containing particles indicates the importance of copper-wood interactions to determine the formation and distribution of copper species in wood components. Our findings will advance the fundamental understanding of their released forms, potential transformation, and environmental fate during the life cycle.
