Viewing violent policing videos contributes to trauma symptoms for Black Americans.

OBJECTIVE: This research investigates how watching videos of police violence and experiences with police contributes to health disparities in well-being that disproportionately negatively affect Black Americans. METHOD: A large-scale survey of Americans (n = 1,240; nBlack American = 286, nWhite American = 954) examined the impact of negative experiences with police and watching violent policing videos as distal (i.e., external) stressors that contribute to symptoms of trauma. The proximal (i.e., internal) stressor of worrying about being stereotyped as criminal by police was also examined. RESULTS: Those who identified as Black were more likely to report negative experiences with police, exposure to violent policing videos, and greater worry about being stereotyped as criminal by police than those who identified as White. The three stressors were, in turn, associated with experiencing trauma symptoms. CONCLUSIONS: Exposure to violent policing videos is disproportionately associated with well-being for Black Americans, even when accounting for direct experiences with police. These findings demonstrate the importance of considering vicarious trauma in therapeutic settings and have implications for dissemination of these videos through media channels.

Perceived stress increases susceptibility to visual food cues in fast-food menu selections.

Individuals who report perceived stress often eat more unhealthy foods and more calories than those with lower stress levels, though individual differences and contexts are important. This study investigated how visual food cues on fast-food menus may increase calorie consumption intentions due to their potential motivational influences. A 2 (presence or absence of visual cues) x 4 (exemplar fast-food restaurant menu) fractionated experiment administered online (N = 325) indicated that when participants viewed menus with visual cues, they selected a greater number of calories to consume. Additionally, data showed an interaction effect of perceived stress and visual cues revealing that visual elements incentivized participants reporting higher stress to select more calories whereas visual cues did not have this effect for people reporting lower levels of perceived stress. Though important limitations exist, a key takeaway is that food cue exposure is another important factor to consider when predicting how stress may affect eating decisions.

The importance of being animate: Information selection as a function of dynamic human-environment interactions.

This study examined whether the stability of highly relevant animate and inanimate information predicted encoding. Participants (N = 149 young adults) viewed audiovisual media and completed a change detection task of screenshots taken from the viewing session. The screenshots were either left as originally viewed or a factor was altered. The factors were all motivationally (relevant to biological imperatives) and story (relevant to the ongoing narrative) relevant. Half were part of an animal and half were part of other environmental information. This was crossed with whether the information was stable or fleeting in the scene (e.g., a person's clothing vs. their gestures). Changes to animals were more recognized than inanimate information. Changes to fleeting inanimate information were better recognized than changes to stable inanimate information. These findings indicate potential for relevant change in environmental threat and opportunity is adaptively significant and likely to increase attention and encoding across animate and inanimate categories of information.

Decrements in lung function and respiratory abnormalities associated with exposure to diacetyl and 2,3-pentanedione in coffee production workers.

Coffee production workers are exposed to complex mixtures of gases, dust, and vapors, including the known respiratory toxins, diacetyl, and 2,3-pentanedione, which occur naturally during coffee roasting and are also present in flavorings used to flavor coffee. This study evaluated the associations of these two α-diketones with lung function measures in coffee production workers. Workers completed questionnaires, and their lung function was assessed by spirometry and impulse oscillometry (IOS). Personal exposures to diacetyl, 2,3-pentanedione, and their sum (SumDA+PD) were assigned to participants, and metrics of the highest 95th percentile (P95), cumulative, and average exposure were calculated. Linear and logistic regression models for continuous and binary/polytomous outcomes, respectively, were used to explore exposure-response relationships adjusting for age, body mass index, tenure, height, sex, smoking status, race, or allergic status. Decrements in percent predicted forced expiratory volume in 1 second (ppFEV1) and forced vital capacity (ppFVC) were associated with the highest-P95 exposures to 2,3-pentanedione and SumDA+PD. Among flavoring workers, larger decrements in ppFEV1 and ppFVC were associated with highest-P95 exposures to diacetyl, 2,3-pentanedione, and SumDA+PD. Abnormal FEV1, FVC, and restrictive spirometric patterns were associated with the highest-P95, cumulative, and average exposures for all α-diketone metrics; some of these associations were also present among flavoring and non-flavoring workers. The combined category of small and peripheral airways plus small and large airways abnormalities on IOS had elevated odds for highest-P95 exposure to α-diketones. These results may be affected by the small sample size, few cases of abnormal spirometry, and the healthy worker effect. Associations between lung function abnormalities and exposure to α-diketones suggest it may be prudent to consider exposure controls in both flavoring and non-flavoring settings.

Fast food menu calorie labeling contexts as complex contributing factors to overeating.

The effectiveness of menu calorie labeling in limiting the amount of calories selected has been called into question since it was mandated within the Affordable Care Act. This study examined how contexts that are known to influence motivational and information processing might limit the effectiveness of calorie labeling in order to shed some light on the mixed findings in this area. An online experiment was conducted in which calorie labels were paired or not paired with visual cues in different motivational contexts: greater and lesser variety and energy density choices available. Results contribute to the general conclusion that calorie labels are not particularly effective. Specifically, the only context in which a calorie label succeeded in reducing calories selected was a high variety mix of low and high energy density foods with visual food cues present; however, this type of context elicited the greatest number of calories selected on average, even more than when only highly energy density items were present. The findings from this study add to the body of knowledge about the effectiveness of calorie labeling by defining some boundary conditions on whether and when the presence of calorie labels are likely to reduce caloric intake. This knowledge is helpful in furthering food selection and choice research, but also may help health practitioners design effective intervention strategies.

Social Facilitation in Fear Appeals Creates Positive Affect but Inhibits Healthy Eating Intentions.

The social facilitation of eating plays a significant role in influencing individuals' eating decisions. However, how social eating cues are processed in health promotion messages is unclear. This study examined individuals' food craving in response to social cues in images (Experiment 1) and emotional experiences, perceived threat, perceived efficacy, behavioral intentions, and motivational coactivation elicited by social eating cues in obesity prevention fear appeals (Experiment 2). Results suggested that the presence of a group of people eating in an image facilitated food craving for the presented foods. Moreover, fear appeals that presented obesity and its consequences with more social eating cues, versus individual eating cues, generated greater positive emotional responses, perceived threat severity, response and self-efficacy, and motivational coactivation indicating more attention and threat vigilance. However, these cues also generated fewer self-reported intentions to change unhealthy eating behaviors. Implications and suggestions for future research are discussed.

Family visitation policies, facilities, and support in Australia and New Zealand intensive care units: A multicentre, registry-linked survey.

OBJECTIVE: The objective of this study was to describe family visitation policies, facilities, and support in Australia and New Zealand (ANZ) intensive care units (ICUs). METHODS: A survey was distributed to all Australian and New Zealand ICUs reporting to the Australian and New Zealand Intensive Care Society Centre for Outcomes and Resources Evaluation Critical Care Resources (CCR) Registry in 2018. Data were obtained from the survey and from data reported to the CCR Registry. For this study, open visiting (OV) was defined as allowing visitors for more than 14 h per day. SETTING AND PARTICIPANTS: This study included all Australian and New Zealand ICUs reporting to CCR in 2018. MAIN OUTCOME MEASURES: The main outcome measures were family access to the ICU and visiting hours, characteristics of the ICU waiting area, and information provided to and collected from the relatives. FINDINGS: Fifty-six percent (95/170) of ICUs contributing to CCR responded, representing 44% of ANZ ICUs and a range of rural, metropolitan, tertiary, and private ICUs. Visiting hours ranged from 1.5 to 24 h per day, with 68 (72%) respondent ICUs reporting an OV policy, of which 64 (67%) ICUs were open to visitors 24 h a day. A waiting room was part of the ICU for 77 (81%) respondent ICUs, 74 (78%) reported a separate dedicated room for family meetings, and 83 (87%) reported available social worker services. Most ICUs reported facilities for sleeping within or near the hospital. An information booklet was provided by 64 (67%) ICUs. Only six (6%) ICUs required personal protective equipment for all visitors, and 76 (80%) required personal protective equipment for patients with airborne precautions. CONCLUSIONS: In 2018, the majority of ANZ ICUs reported liberal visiting policies, with substantial facilities and family support.

Staff perceptions of family access and visitation policies in Australian and New Zealand intensive care units: The WELCOME-ICU survey.

BACKGROUND: Family-centred critical care recognises the impact of a loved one's critical illness on his relatives. Open visiting is a strategy to improve family satisfaction and psychological outcomes by permitting unrestricted or less restricted access to visit their family member in the intensive care unit (ICU). However, increased family presence may result in increased workload and a risk of burnout for ICU staff. OBJECTIVES: The objective of this study was to evaluate ICU staff perceptions regarding visiting hours and family access in Australian and New Zealand ICUs. Secondary outcomes included an evaluation of current visiting policies, witnessed events in ICUs, and barriers to implementing open visiting policies. DESIGN: A web-based survey open to all healthcare workers in Australia and New Zealand ICUs was distributed through local, state-based, and national critical care networks. Open visiting was defined as ICUs open for visiting >14 h per day. MAIN RESULTS: We received 1255 valid responses. Most respondents were nurses (n = 930, 74.1%) with a median critical care experience of 10 y. Most worked in open visiting ICUs (n = 749, 59.7%). Reported visiting hours varied greatly with a median of 20 h per day (interquartile range: 10-24 h). Open visiting was perceived as beneficial for the relatives, but less so for patients and staff (relatives: n = 845, 67.3%, patients: n = 561, 44.7%, staff: n = 257, 20.5%, p < 0.0001). Respondents from closed visiting units and nurses identified more risks from open visiting than other professional groups. Generally, staff preferred not to change from their current practice. CONCLUSION: We report that staff perceived open visiting as beneficial for relatives, but also identified risks to themselves, including increased workload, a risk of burnout, and a risk of occupational violence. Reluctance to change highlights the importance of addressing staff perceptions when implementing an open visiting policy.

The Influence of Social Eating Norms on Motivational Responses When Processing Fast Food Advertisements.

Social norms play a key role in dietary behaviors. This study tested the underlying mechanism behind social norm effects in the context of the influences of social eating cues (individual vs. group eating cues) in fast food advertisements on motivational responses. Our results indicated that food ads with group eating cues elicited stronger appetitive activation resulting in greater orbicularis oculi activation and greater skin conductivity level, indicating more positive emotional feelings and more sympathetic arousal, compared to food ads with individual eating cues. Group eating cues also led to more favorable self-reported attitudes toward the advertised food products and brands. Overall, findings from this study suggest that exposure to food ads with group eating cues yield greater appetitive responses toward these types of ads and their products, likely creating a stronger degree of perceived social support. Implications are discussed.

Evaluation of CME Arrival Prediction Using Ensemble Modeling Based on Heliospheric Imaging Observations.

In this study, we evaluate a coronal mass ejection (CME) arrival prediction tool that utilizes the wide-angle observations made by STEREO's heliospheric imagers (HI). The unsurpassable advantage of these imagers is the possibility to observe the evolution and propagation of a CME from close to the Sun out to 1 AU and beyond. We believe that by exploiting this capability, instead of relying on coronagraph observations only, it is possible to improve today's CME arrival time predictions. The ELlipse Evolution model based on HI observations (ELEvoHI) assumes that the CME frontal shape within the ecliptic plane is an ellipse and allows the CME to adjust to the ambient solar wind speed; that is, it is drag based. ELEvoHI is used to perform ensemble simulations by varying the CME frontal shape within given boundary conditions that are consistent with the observations made by HI. In this work, we evaluate different setups of the model by performing hindcasts for 15 well-defined isolated CMEs that occurred when STEREO was near L4/5, between the end of 2008 and the beginning of 2011. In this way, we find a mean absolute error of between 6.2 ± 7.9 and 9.9 ± 13 hr depending on the model setup used. ELEvoHI is specified for using data from future space weather missions carrying HIs located at L5 or L1. It can also be used with near-real-time STEREO-A HI beacon data to provide CME arrival predictions during the next ∼7 years when STEREO-A is observing the Sun-Earth space.

Occupational Histoplasmosis: Epidemiology and Prevention Measures.

In areas where Histoplasma is endemic in the environment, occupations involving activities exposing workers to soil that contains bird or bat droppings may pose a risk for histoplasmosis. Occupational exposures are frequently implicated in histoplasmosis outbreaks. In this paper, we review the literature on occupationally acquired histoplasmosis. We describe the epidemiology, occupational risk factors, and prevention measures according to the hierarchy of controls.

Case Report: Flavoring-Related Lung Disease in a Coffee Roasting and Packaging Facility Worker With Unique Lung Histopathology Compared With Previously Described Cases of Obliterative Bronchiolitis.

Occupational exposure to diacetyl, a butter flavor chemical, can result in obliterative bronchiolitis. Obliterative bronchiolitis is characterized by exertional dyspnea, fixed airflow obstruction, and histopathologic constrictive bronchiolitis, with bronchiolar wall fibrosis leading to luminal narrowing and obliteration. We describe a case of advanced lung disease with histopathology distinct from obliterative bronchiolitis in a 37-year-old male coffee worker following prolonged exposure to high levels of diacetyl and the related compound 2,3-pentanedione, who had no other medical, avocational, or occupational history that could account for his illness. He began working at a coffee facility in the flavoring room and grinding area in 2009. Four years later he moved to the packaging area but continued to flavor and grind coffee at least 1 full day per week. He reported chest tightness and mucous membrane irritation when working in the flavoring room and grinding area in 2010. Beginning in 2014, he developed dyspnea, intermittent cough, and a reduced sense of smell without a work-related pattern. In 2016, spirometry revealed a moderate mixed pattern that did not improve with bronchodilator. Thoracoscopic lung biopsy results demonstrated focal mild cellular bronchiolitis and pleuritis, and focal peribronchiolar giant cells/granulomas, but no evidence of constrictive bronchiolitis. Full-shift personal air-samples collected in the flavoring and grinding areas during 2016 measured diacetyl concentrations up to 84-fold higher than the recommended exposure limit. Medical evaluations indicate this worker developed work-related, airway-centric lung disease, most likely attributable to inhalational exposure to flavorings, with biopsy findings not usual for obliterative bronchiolitis. Clinicians should be aware that lung pathology could vary considerably in workers with suspected flavoring-related lung disease.

Applying Optimal Foraging to Young Adult Decision-Making after Food Advertising Exposure.

This study combined theory from the fields of communication, behavioral ecology, and ecological psychology to examine how relevant factors about food influence the timing and trajectory of our decision-making after exposure to food advertisements. Young healthy adult participants (N = 108) completed a forced-choice, speeded decision-making latency task before and after viewing a set of advertisements. Results suggested that participants were more appetitively motivated by more energy-dense foods (i.e., higher calorie per gram) using direct food cues (i.e., were directly available to the senses, were visible), but after exposure to advertisements, this predisposition was less pronounced. Advertisement food cues were also important in decision-making, especially in coalition with the food cues used in the decision-making task stimuli. This study supports an optimal foraging perspective being expanded to human behavioral contexts in a modern landscape. Food advertising and packaging cues interacted with energy density level of food to provide information relevant to biological imperatives, which significantly altered food consumption decisions.

Exposures and Emissions in Coffee Roasting Facilities and Cafés: Diacetyl, 2,3-Pentanedione, and Other Volatile Organic Compounds.

Roasted coffee and many coffee flavorings emit volatile organic compounds (VOCs) including diacetyl and 2,3-pentanedione. Exposures to VOCs during roasting, packaging, grinding, and flavoring coffee can negatively impact the respiratory health of workers. Inhalational exposures to diacetyl and 2,3-pentanedione can cause obliterative bronchiolitis. This study summarizes exposures to and emissions of VOCs in 17 coffee roasting and packaging facilities that included 10 cafés. We collected 415 personal and 760 area full-shift, and 606 personal task-based air samples for diacetyl, 2,3-pentanedione, 2,3-hexanedione, and acetoin using silica gel tubes. We also collected 296 instantaneous activity and 312 instantaneous source air measurements for 18 VOCs using evacuated canisters. The highest personal full-shift exposure in part per billion (ppb) to diacetyl [geometric mean (GM) 21 ppb; 95th percentile (P95) 79 ppb] and 2,3-pentanedione (GM 15 ppb; P95 52 ppb) were measured for production workers in flavored coffee production areas. These workers also had the highest percentage of measurements above the NIOSH Recommended Exposure Limit (REL) for diacetyl (95%) and 2,3-pentanedione (77%). Personal exposures to diacetyl (GM 0.9 ppb; P95 6.0 ppb) and 2,3-pentanedione (GM 0.7 ppb; P95 4.4 ppb) were the lowest for non-production workers of facilities that did not flavor coffee. Job groups with the highest personal full-shift exposures to diacetyl and 2,3-pentanedione were flavoring workers (GM 34 and 38 ppb), packaging workers (GM 27 and 19 ppb) and grinder operator (GM 26 and 22 ppb), respectively, in flavored coffee facilities, and packaging workers (GM 8.0 and 4.4 ppb) and production workers (GM 6.3 and 4.6 ppb) in non-flavored coffee facilities. Baristas in cafés had mean full-shift exposures below the RELs (GM 4.1 ppb diacetyl; GM 4.6 ppb 2,3-pentanedione). The tasks, activities, and sources associated with flavoring in flavored coffee facilities and grinding in non-flavored coffee facilities, had some of the highest GM and P95 estimates for both diacetyl and 2,3-pentanedione. Controlling emissions at grinding machines and flavoring areas and isolating higher exposure areas (e.g., flavoring, grinding, and packaging areas) from the main production space and from administrative or non-production spaces is essential for maintaining exposure control.

Spirometric Abnormalities and Lung Function Decline in Current and Former Microwave Popcorn and Current Flavoring Manufacturing Workers.

OBJECTIVE: The aim of this study was to compare spirometry results in microwave popcorn and flavoring manufacturing workers. METHODS: We used NIOSH data on current and former microwave popcorn workers (MPWs) and surveillance data on flavoring manufacturing workers (FMWs). RESULTS: Former MPW had higher prevalence of mixed and high severity abnormalities, some had excessive lung function drops. Current MPW had lowest occurrence of excessive lung function drops. FMW with excessive drops and spirometric abnormalities at last test had developed a restrictive pattern. Spirometric abnormalities and excessive drops were associated with work-related factors. CONCLUSION: There was evidence of a healthy worker survivor effect in MPW. Importantly, removal from exposure did not always stabilize lung function decline indicating a need for continued monitoring. The development of a restrictive pattern should raise the level of suspicion for possible work-related disease in flavoring-exposed workers.

The Burden of Respiratory Abnormalities Among Workers at Coffee Roasting and Packaging Facilities.

Introduction: Respiratory hazards in the coffee roasting and packaging industry can include asthmagens such as green coffee bean and other dust and alpha-diketones such as diacetyl and 2,3-pentanedione that can occur naturally from roasting coffee or artificially from addition of flavoring to coffee. We sought to describe the burden of respiratory abnormalities among workers at 17 coffee roasting and packaging facilities. Methods: We completed medical surveys at 17 coffee roasting and packaging facilities that included interviewer-administered questionnaires and pulmonary function testing. We summarized work-related symptoms, diagnoses, and spirometry testing results among all participants. We compared health outcomes between participants who worked near flavoring and who did not. Results: Participants most commonly reported nose and eye symptoms, and wheeze, with a work-related pattern for some. Symptoms and pulmonary function tests were consistent with work-related asthma in some participants. About 5% of workers had abnormal spirometry and most improved after bronchodilator. Health outcomes were similar between employees who worked near flavoring and who did not, except employees who worked near flavoring reported more chronic bronchitis and ever receiving a diagnosis of asthma than those who did not work near flavoring. Conclusion: The symptoms and patterns likely represent overlapping health effects of different respiratory hazards, including green coffee bean and other dust that can contribute to work-related asthma, and diacetyl and 2,3-pentanedione that can contribute to obliterative bronchiolitis. Healthcare providers and occupational health and safety practitioners should be aware that workers at coffee roasting and packaging facilities are potentially at risk for occupational lung diseases.

Smoking Status Matters: A Direct Comparison of Smokers' and Nonsmokers' Psychophysiological and Self-Report Responses to Secondhand Smoke Anti-Tobacco PSAs.

Extensive research demonstrates that exposure to threatening anti-tobacco messages can lead to defensive message processing which reduces message effectiveness. However, research investigating whether this effect is moderated by the smoking status of the message viewer is lacking. In this study, participants (N = 48 smokers and N = 51 non-smokers) viewed and rated secondhand smoke anti-tobacco messages depicting both smoking cues and threat content, or messages depicting neither while heart rate, skin conductance, and facial EMG were recorded. Post viewing, self-reported emotional experience, level of counterarguing, and recognition memory were measured. In support of the LC4MP, there were no differences between smokers and non-smokers' responses for non-threatening messages absent in smoking cues. However, messages that contained both smoking cues and threat content were defensively processed by smokers - but not non-smokers - as indicated by significantly faster heart rate, lower recognition memory and higher self-reported negativity, arousal, and counterarguments. The theoretical and practical implications are discussed.

Investigating the Effect of Use and Social Cues in Food Advertisements on Attention, Feelings of Social Support, and Purchase Intention.

In an effort to understand how different types of food cues in food ads are automatically encouraging unhealthy eating behaviors, the current study examined how the presence of actual food consumption behaviors (use cues) and presence of multiple individuals indorsing food products (social cues) in fast food ads would influence individual attentional and behavioral responses. A use cue (2) x social cue (2) x repetition (3) fully within-subjects factorial design experiment with young adults (N = 164) was conducted. Findings demonstrated that participants paid greater attention to the fast food ads which contained multiple people (group cue) eating the advertised food products (use cue) when compared to other types of fast food ads. In addition, participants also self-reported greater social support and purchase intention when seeing use and group cues in ads. Understanding how these cues function in food advertising to encourage unhealthy eating may help health practitioners and individuals create more helpful intervention strategies. Further, applying these marketing tactics to ads for food products that are healthier (i.e., less energy dense and more nutrient dense) may help to maximize healthy food palatability, thereby increasing motivation for viewers to make autonomous decisions about eating healthier.

Conditioned "Cross Fading": The Incentive Motivational Effects of Mediated-Polysubstance Pairings on Alcohol, Marijuana, and Junk Food Craving.

The bulk of mass media and substance cue research has examined the processes and effects of substance cue images in isolation under controlled experimental conditions. However, little attention has been devoted to delineating the specific outcomes associated with simultaneous polysubstance depictions. This study experimentally examined whether alcohol, marijuana, and junk food mediated cues influence craving independently and whether craving for these substances is co-facilitated by simultaneous polysubstance cue depictions. At a laboratory session, participants reported their craving to substance cues in isolation and when paired with one another. The results from this study support the incentive sensitization model and polysubstance literature indicating that alcohol and marijuana cues facilitate craving for both alcohol and marijuana above and beyond when alcohol and marijuana cues are depicted in isolation for high and low users of each substance. Junk food craving was not facilitated by alcohol and marijuana cues. Theoretically, this study supports the notion that simultaneous and repeated use of multiple substances results in greater hypersensitivity and craving to mediated polysubstance cues than the cues in isolation. Practically, this study provides a word of caution for researchers examining craving responses to mediated substance cue messages and recommendations for health professionals and message designers.
