Indigenous communities in Taiwan shoulder a disproportionate burden of unintentional injury fatalities. We compare unintentional injury mortality rate trends among Taiwan's indigenous communities and the general population from 2002 to 2013, and evaluate potential impact of a community-based injury prevention programme on indigenous unintentional injury death rates. Standardised and crude unintentional injury mortality rates were obtained from Taiwan government reports. Segmented linear regression was used to estimate and compare unintentional injury mortality rate trends before and after the intervention. Between 2002 and 2013, unintentional injury mortality rates among Taiwan's indigenous population significantly declined by about 4.5 deaths per 100 000 each year (p<0.0001). During that time, the unintentional injury mortality rate ratio between indigenous Taiwanese and the general population significantly decreased by approximately 1% each successive year (p=0.02). However, we were unable to detect evidence that the 'Healthy and Safe Tribe' programme was associated with a statistically significant decrease in the unintentional injury mortality rate trend among indigenous persons (p=0.81). Taiwanese indigenous communities remain at significantly higher risk of unintentional injury death, though the gap may be slowly narrowing. We found no evidence that the 'Healthy and Safe Tribe' indigenous injury-prevention programme significantly contributed to the nationwide decline in unintentional injury mortality among indigenous Taiwanese communities from 2009 to 2013. Future interventions to address the disproportionate burden of unintentional injury fatalities among indigenous Taiwanese should consider interventions with wider coverage of the indigenous population, and complementing grass roots led community-based interventions with structural policy interventions as well. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

1998-01-01

The purpose of this study was to determine the annual number and incidence of unintentional deaths from carbon monoxide (CO) poisonings in California and to identify specific factors that caused or contributed to the deaths. Unintentional CO deaths in California over a ten-year period (1979 to 1988) were identified from the database of the California Master Mortality File and coroners' investigation reports. Factors associated with unintentional CO deaths were determined based on the information from the investigation reports. The annual number of unintentional CO deaths varied from 27 to 58 over the ten years examined, with an average annual death incidence of 1.7 x 10(-6). Death rates were high among males and African-Americans. Alcohol appeared to be a factor in 31% of the cases. The types of combustion sources associated with unintentional CO deaths were: heating or cooking appliances; motor vehicles; charcoal grills and hibachis; small engines; and camping equipment. Factors associated with unintentional CO deaths interact in a complex way. To reduce the rate of unintentional CO deaths effectively, joint efforts involving several prevention methods are suggested.

Determinants of Unintentional Leaks During CPAP Treatment in OSA.

Unintentional leakage from the mouth or around the mask may lead to cessation of CPAP treatment; however, the causes of unintentional leaks are poorly understood. The objectives of this study were (1) to identify determining factors of unintentional leakage and (2) to determine the effect of the type of mask (nasal/oronasal) used on unintentional leakage. Seventy-four polysomnograms from patients with OSA syndrome treated with auto-CPAP were analyzed (23 women; 56 ± 13 years; BMI, 32.9 kg/m 2 (range, 29.0-38.0 kg/m 2 ). Polysomnographic recordings were obtained under auto-CPAP, and mandibular behavior was measured with a magnetic sensor. After sleep and respiratory scoring, polysomnographic signals were computed as mean values over nonoverlapping 10-s intervals. The presence/absence of unintentional leakage was dichotomized for each 10-s interval (yes/no). Univariate and multivariate conditional regression models estimated the risk of unintentional leaks during an interval "T" based on the explanatory variables from the previous interval "T-1." A sensitivity analysis for the type of mask was then conducted. The univariate analysis showed that mandibular lowering (mouth opening), a high level of CPAP, body position (other than supine), and rapid eye movement (REM) sleep increased the risk of unintentional leaks and microarousal decreased it. In the multivariate analysis, the same variables remained independently associated with an increased risk of unintentional leakage. The sensitivity analysis showed that oronasal masks reduced the risk of unintentional leaks in cases of mouth opening and REM sleep. Mouth opening, CPAP level, sleep position, and REM sleep independently contribute to unintentional leakage. These results provide a strong rationale for the definition of phenotypes and the individual management of leaks during CPAP treatment. Copyright © 2017 American College of Chest Physicians.

To investigate general unintentional injuries (GUI) and traumatic dental injuries (TDI) in relation to behavioral and psychosocial strengths and difficulties among Swedish children aged 0-17 years, and to investigate general unintentional injuries in relation to temperament and socioeconomic status among the same children. The study included 2363 children in four different age cohorts aged 3, 7, 11, and 15 years at the study start. Twelve Public Dental Service clinics in Sweden participated, representing different types of demographic areas, both rural and urban. Data were collected from parents and children through an interview, questionnaires, and dental records. Twenty-four percentage (24%) of the children had experienced a serious general unintentional injury (GUI) at some point during their lifetime up until 3 months prior to the study start. Children who were regarded by their parents as being injured more often than other children also had occasions with general unintentional injuries to a greater extent. Most general unintentional injuries occurred at home. Children with incidents of general unintentional injuries had occasions with TDI to a greater extent than children without general unintentional injury. Children, whose mothers had 11 years of school/education or less, were involved in more general unintentional injuries during the 3-month period prior to the study start, compared to children of mothers with higher education level. Children with general unintentional injuries had more traumatic dental injuries. Children who were assessed by their parents as being injured more often than other children also had occasions with general unintentional injuries to a greater extent. Temperament, behavioral and psychosocial strengths and difficulties had different impacts at different ages for experiencing a general unintentional injury. © 2016 John Wiley & Sons A/S.

"The empathy impulse: A multinomial model of intentional and unintentional empathy for pain": Correction.

Reports an error in "The empathy impulse: A multinomial model of intentional and unintentional empathy for pain" by C. Daryl Cameron, Victoria L. Spring and Andrew R. Todd ( Emotion , 2017[Apr], Vol 17[3], 395-411). In this article, there was an error in the calculation of some of the effect sizes. The w effect size was manually computed incorrectly. The incorrect number of total observations was used, which affected the final effect size estimates. This computing error does not change any of the results or interpretations about model fit based on the G² statistic, or about significant differences across conditions in process parameters. Therefore, it does not change any of the hypothesis tests or conclusions. The w statistics for overall model fit should be .02 instead of .04 in Study 1, .01 instead of .02 in Study 2, .01 instead of .03 for the OIT in Study 3 (model fit for the PIT remains the same: .00), and .02 instead of .03 in Study 4. The corrected tables can be seen here: http://osf.io/qebku at the Open Science Framework site for the article. (The following abstract of the original article appeared in record 2017-01641-001.) Empathy for pain is often described as automatic. Here, we used implicit measurement and multinomial modeling to formally quantify unintentional empathy for pain: empathy that occurs despite intentions to the contrary. We developed the pain identification task (PIT), a sequential priming task wherein participants judge the painfulness of target experiences while trying to avoid the influence of prime experiences. Using multinomial modeling, we distinguished 3 component processes underlying PIT performance: empathy toward target stimuli (Intentional Empathy), empathy toward prime stimuli (Unintentional Empathy), and bias to judge target stimuli as painful (Response Bias). In Experiment 1, imposing a fast (vs. slow) response deadline uniquely reduced Intentional Empathy. In Experiment 2, inducing imagine-self (vs. imagine-other) perspective-taking uniquely increased Unintentional Empathy. In Experiment 3, Intentional and Unintentional Empathy were stronger toward targets with typical (vs. atypical) pain outcomes, suggesting that outcome information matters and that effects on the PIT are not reducible to affective priming. Typicality of pain outcomes more weakly affected task performance when target stimuli were merely categorized rather than judged for painfulness, suggesting that effects on the latter are not reducible to semantic priming. In Experiment 4, Unintentional Empathy was stronger for participants who engaged in costly donation to cancer charities, but this parameter was also high for those who donated to an objectively worse but socially more popular charity, suggesting that overly high empathy may facilitate maladaptive altruism. Theoretical and practical applications of our modeling approach for understanding variation in empathy are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

A two-in-one process for reliable graphene transistors processed with photo-lithography

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ahlberg, P.; Hinnemo, M.; Song, M.

2015-11-16

Research on graphene field-effect transistors (GFETs) has mainly relied on devices fabricated using electron-beam lithography for pattern generation, a method that has known problems with polymer contaminants. GFETs fabricated via photo-lithography suffer even worse from other chemical contaminations, which may lead to strong unintentional doping of the graphene. In this letter, we report on a scalable fabrication process for reliable GFETs based on ordinary photo-lithography by eliminating the aforementioned issues. The key to making this GFET processing compatible with silicon technology lies in a two-in-one process where a gate dielectric is deposited by means of atomic layer deposition. During thismore » deposition step, contaminants, likely unintentionally introduced during the graphene transfer and patterning, are effectively removed. The resulting GFETs exhibit current-voltage characteristics representative to that of intrinsic non-doped graphene. Fundamental aspects pertaining to the surface engineering employed in this work are investigated in the light of chemical analysis in combination with electrical characterization.« less

Unintentional Injuries among Psychiatric Outpatients with Major Depressive Disorder.

Hung, Ching-I; Liu, Chia-Yih; Yang, Ching-Hui

2016-01-01

No study has investigated the percentages of and factors related to unintentional injuries among psychiatric outpatients with major depressive disorder (MDD). This study aimed to investigate these issues. One-hundred and forty-one outpatients with MDD at baseline were enrolled from psychiatric outpatients by systematic sampling, and 119 subjects attended a one-year follow-up. Self-reported unintentional injuries in the past one year were recorded. Psychiatric disorders were diagnosed using the Structured Clinical Interview for DSM-IV-TR. The severity of depression was evaluated by the Hamilton Depression Rating Scale. Other data, including body weight and height, cigarette smoking, headaches, and medications, were collected. Generalized Estimating Equations were used to investigate independent factors related to unintentional injuries. At baseline and follow-up, 40.4% and 27.7% of subjects had experienced at least one unintentional injury in the past one year, respectively. About half of subjects with unintentional injuries needed medical treatment for injuries and had functional impairment due to injuries. A greater severity of depression, cigarette smoking, a higher body mass index, and an older age were independent risk factors related to unintentional injuries. Unintentional injuries that increased the medical burden and functional impairment were common among outpatients with MDD and should not be neglected. Treatment of depression, control of body weight, and quitting cigarettes might be helpful to prevent unintentional injuries.

Burns are major cause of morbidity and mortality in developing countries. Better understanding of the nature and extent of injury remains the major and only available way to halt the occurrence of the event. The present study was conducted to determine the prevalence of by self and by other unintentional burn, their comparison and the possible mode of acquisition by obtaining the history of exposure to known risk factors. A cross-sectional questionnaire based survey was conducted in Burns Centre of Civil Hospital Karachi, Pakistan and 324 hospitalized adult patients with unintentional burns were consecutively interviewed during August 2013 to February 2014. Information was collected on socio-demographic profile. The source of burn, affected body part and place of injury acquisition in terms of home, outside or work were also noted. Logistic regression model was conducted using SPSS software. Out of 324 patients, 295 (91%) had unintentional burn by self and 29 (9%) had unintentional burn by others. Male gender were 2.37 times and no schooling were 1.75 times more likely to have self-inflicted unintentional burn. Lower limb and head and neck were less likely to involve in unintentional burn by self. The burden of unintentional burn by self was considerably higher. Male gender and no schooling were found more at risk to have unintentional burn by self. Copyright © 2016 Elsevier Ltd and ISBI. All rights reserved.

Damage to the ventromedial prefrontal cortex is associated with impairments in both spontaneous and deliberative moral judgments

2018-01-01

Implicit moral evaluations—spontaneous, unintentional judgments about the moral status of actions or persons—are thought to play a pivotal role in moral experience, suggesting a need for research to model these moral evaluations in clinical populations. Prior research reveals that the ventromedial prefrontal cortex (vmPFC) is a critical area underpinning affect and morality, and patients with vmPFC lesions show abnormalities in moral judgment and moral behavior. We use indirect measurement and multinomial modeling to understand differences in implicit moral evaluations among patients with vmPFC lesions. Our model quantifies multiple processes of moral judgment: implicit moral evaluations in response to distracting moral transgressions (Unintentional Judgment), accurate moral judgments about target actions (Intentional Judgment), and a directional tendency to judge actions as morally wrong (Response Bias). Compared to individuals with non-vmPFC brain damage and neurologically healthy comparisons, patients with vmPFC lesions showed a dual deficit in processes of moral judgment. First, patients with vmPFC lesions showed reduced Unintentional Judgment about moral transgressions, but not about non-moral negative affective distracters. Second, patients with vmPFC lesions showed reduced Intentional Judgment about target actions. These findings highlight the utility of a formal modeling approach in moral psychology, revealing a dual deficit in multiple component processes of moral judgment among patients with vmPFC lesions.

To evaluate the associations of perception of safety atmosphere at workplace, occupational safety attitude and behaviors with occupational unintentional injury among manufacturing workers. A cross-sectional study was performed and a self-administered questionnaire was used to inquire socio-demographic characteristics, perceived safety atmosphere, occupational safety attitudes, occupational safety behaviors and occupational unintentional injuries among 10585 manufacturing workers selected from 46 enterprises in Guangdong. Structural equation modeling was applied to assess the relationship of the perception of safety atmosphere at workplace, occupational safety attitude, and occupational safety behaviors with occupational unintentional injury. Among 24 pathways supposed in structural equation model, 20 pathways (except for the attitude toward occupational safety, the attitude toward managers' support, the work posture and individual protection) were significantly related to the occupational unintentional injuries. The further analysis indicated that the perceived safety atmosphere might impact the occupational unintentional injuries by the attitude toward occupational safety and occupational safety behaviors. Workers' perception of safety atmosphere indirectly influenced on occupational unintentional injuries through occupational safety attitudes and occupational safety behaviors.

What did you have in mind? Examining the content of intentional and unintentional types of mind wandering

PubMed Central

Seli, Paul; Ralph, Brandon C. W.; Konishi, Mahiko; Smilek, Daniel; Schacter, Daniel L.

2017-01-01

It has recently been argued that researchers should distinguish between mind wandering (MW) that is engaged with and without intention. Supporting this argument, studies have found that intentional and unintentional MW have behavioral/neural differences, and that they are differentially associated with certain variables of theoretical interest. Although there have been considerable inroads made into the distinction between intentional/unintentional MW, possible differences in their content remain unexplored. To determine whether these two types of MW differ in content, we had participants complete a task during which they categorized their MW as intentional or unintentional, and then provided responses to questions about the content of their MW. Results indicated that intentional MW was more frequently rated as being future-oriented and less vague than unintentional MW. These findings shed light on the nature of intentional and unintentional MW and provide support for the argument that researchers should distinguish between intentional and unintentional types.

Unintentional injuries are predictable and preventable. Yet every hour, a child in the United States dies from an unintentional injury. Globally, the number is even more staggering, with nearly 1 million children dying from unintentional injuries each year. Motor vehicle-related injuries, burns, drowning, falls, suffocation or choking, and poisoning are just a few of the unintentional injury risks threatening children. Patient safety requires a three-pronged strategy of behavior change, use of safety devices, and improvement of laws and regulations to ensure that all children lead healthy and productive lives.

Bailey, Stephanie L.; Bono, Rose S.; Nash, Denis; Kimmel, April D.

2018-01-01

Background Spreadsheet software is increasingly used to implement systems science models informing health policy decisions, both in academia and in practice where technical capacity may be limited. However, spreadsheet models are prone to unintentional errors that may not always be identified using standard error-checking techniques. Our objective was to illustrate, through a methodologic case study analysis, the impact of unintentional errors on model projections by implementing parallel model versions. Methods We leveraged a real-world need to revise an existing spreadsheet model designed to inform HIV policy. We developed three parallel versions of a previously validated spreadsheet-based model; versions differed by the spreadsheet cell-referencing approach (named single cells; column/row references; named matrices). For each version, we implemented three model revisions (re-entry into care; guideline-concordant treatment initiation; immediate treatment initiation). After standard error-checking, we identified unintentional errors by comparing model output across the three versions. Concordant model output across all versions was considered error-free. We calculated the impact of unintentional errors as the percentage difference in model projections between model versions with and without unintentional errors, using +/-5% difference to define a material error. Results We identified 58 original and 4,331 propagated unintentional errors across all model versions and revisions. Over 40% (24/58) of original unintentional errors occurred in the column/row reference model version; most (23/24) were due to incorrect cell references. Overall, >20% of model spreadsheet cells had material unintentional errors. When examining error impact along the HIV care continuum, the percentage difference between versions with and without unintentional errors ranged from +3% to +16% (named single cells), +26% to +76% (column/row reference), and 0% (named matrices). Conclusions Standard error-checking techniques may not identify all errors in spreadsheet-based models. Comparing parallel model versions can aid in identifying unintentional errors and promoting reliable model projections, particularly when resources are limited. PMID:29570737

Relationships between depressive symptoms and self-reported unintentional injuries: the cross-sectional population–based FIN-D2D survey

PubMed Central

2012-01-01

Background There is a lack of knowledge on the influence of different levels of physical activity (PA) on unintentional injuries among those with depressive symptoms (DS). The aim of this study was to evaluate the relationship between PA categories and unintentional injuries among participants with and without DS based on a cross-sectional population–based FIN-D2D survey conducted in 2007. Methods Out of 4500, 2682 participants (60%) aged 45–74 years attended in this study. The unintentional injuries over the past year were captured in a questionnaire. DS were determined with the Beck Depression Inventory (≥ 10 points) and PA with the International Physical Activity Questionnaire. The statistical significance between DS and unintentional injury categories was evaluated by using t-test, chi-square test, or permutation test, analysis of covariance, or regression models. The factors related to unintentional injuries were estimated by univariate and multivariate logistic regression models. Results The proportion of subjects with unintentional injuries was higher among those with DS (17%) compared to those without DS (10%) (age- and gender-adjusted p = 0.023). The median (range) number of activity-loss days after injury was 22 (0–365) in participants with DS and 7 (0–120) in participants without DS ( p = 0.009). The percentage of subjects with unintentional injuries was not significantly different between PA categories in participants with DS and without DS. A stepwise multivariate logistic regression analysis showed that DS, functional ability, and musculoskeletal diseases were related to unintentional injuries. Conclusions PA level was not related to unintentional injuries, whereas those with DS had a higher prevalence of unintentional injuries and prolonged activity-loss after injury. These results underline the importance of injury prevention, especially among those who have DS and additional risk factors. PMID:22781103

Effects of Visual Feedback and Memory on Unintentional Drifts in Performance During Finger Pressing Tasks

PubMed Central

Solnik, Stanislaw; Qiao, Mu; Latash, Mark L.

2017-01-01

This study tested two hypotheses on the nature of unintentional force drifts elicited by removing visual feedback during accurate force production tasks. The role of working memory (memory hypothesis) was explored in tasks with continuous force production, intermittent force production, and rest intervals over the same time interval. The assumption of unintentional drifts in referent coordinate for the fingertips was tested using manipulations of visual feedback: Young healthy subjects performed accurate steady-state force production tasks by pressing with the two index fingers on individual force sensors with visual feedback on the total force, sharing ratio, both, or none. Predictions based on the memory hypothesis have been falsified. In particular, we observed consistent force drifts to lower force values during continuous force production trials only. No force drift or drifts to higher forces were observed during intermittent force production trials and following rest intervals. The hypotheses based on the idea of drifts in referent finger coordinates have been confirmed. In particular, we observed superposition of two drift processes: A drift of total force to lower magnitudes and a drift of the sharing ratio to 50:50. When visual feedback on total force only was provided, the two finger forces showed drifts in opposite directions. We interpret the findings as evidence for the control of motor actions with changes in referent coordinates for participating effectors. Unintentional drifts in performance are viewed as natural relaxation processes in the involved systems; their typical time reflects stability in the direction of the drift. The magnitude of the drift was higher in the right (dominant) hand, which is consistent with the dynamic dominance hypothesis. PMID:28168396

2008-01-01

The purpose of this study was to determine the prevalence of lifetime unintentional-injury experience and evaluate the quality of life of unintentional-injury victims, to provide useful data for the development of interventions aimed at decreasing the incidence of unintentional injuries. DESIGN, SAMPLE, AND METHODS: This study utilized data obtained from cross-sectional surveys of 24,327 Korean individuals aged 19-65 years, performed using face-to-face interviews. Demographic characteristics, unintentional-injury experience, attributes of health behavior, and health-related quality of life (HRQoL) questions were included in the study instruments. About 11.8% of the subjects had experienced an unintentional injury that required hospitalization at least once in their lifetime. Being older, being male, having less education and lower income, working in a blue-collar job, and being enrolled in medical aid programs were associated with increased likelihood of having an unintentional injury. Among the HRQoL and risk-taking behavior variables, limitations in daily activities, suicide ideation, and binge drinking were significantly associated with injury experience. Public health efforts to prevent unintentional injuries should target high-risk populations such as males, those with low incomes and education levels, and binge drinkers. Efforts should also be made to enhance the HRQoL of injury victims.

ABSTRACT OBJECTIVE Tto identify factors associated with unintentional sleep at work of airline pilots. METHODS This is a cross-sectional epidemiological study conducted with 1,235 Brazilian airline pilots, who work national or international flights. Data collection has been performed online. We carried out a bivariate and multiple logistic regression analysis, having as dependent variable unintentional sleep at work. The independent variables were related to biodemographic data, characteristics of the work, lifestyle, and aspects of sleep. RESULTS The prevalence of unintentional sleep while flying the airplane was 57.8%. The factors associated with unintentional sleep at work were: flying for more than 65 hours a month, frequent technical delays, greater need for recovery after work, work ability below optimal, insufficient sleep, and excessive sleepiness. CONCLUSIONS The occurrence of unintentional sleep at work of airline pilots is associated with factors related to the organization of the work and health. PMID:28678902

The formation of unintentionally produced persistent organic pollutants (POPs) may occur during various chlorination processes. In this study, emissions of unintentionally produced POPs during the methanol-based production of chlorinated methanes were investigated. High concentrations of highly chlorinated compounds such as decachlorobiphenyl, octachloronaphthalene, octachlorostyrene, hexachlorobutadiene, hexachlorocyclopentadiene, hexachlorobenzene, and pentachlorobenzene were found in the carbon tetrachloride byproduct of the methanol-based production of chlorinated methanes. The total emission amounts of hexachlorocyclopentadiene, hexachlorobutadiene, polychlorinated benzenes, polychlorinated naphthalenes, octachlorostyrene, and polychlorinated biphenyls released during the production of chlorinated methanes in China in 2010 were estimated to be 10080, 7350, 5210, 427, 212, and 167 kg, respectively. Moreover, polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) were formed unintentionally during chlorinated methanes production, the emission factor for PCDDs/DFs was 364 μg toxic equivalency quotient (TEQ) t(-1) product for residues, which should be added into the UNEP toolkit for updating. It was worth noting that a high overall toxic equivalency quotient from polychlorinated naphthalenes and PCDDs/DFs was generated from the chlorinated methanes production in China in 2010. The values reached 563 and 32.8 g TEQ, respectively. The results of the study indicate that more research and improved management systems are needed to ensure that the methanol-based production of chlorinated methanes can be achieved safely.

2011-01-01

AIMS Paracetamol (acetaminophen) hepatotoxicity is the commonest cause of acute liver failure (ALF) in the UK. Conflicting data regarding the outcomes of paracetamol-induced ALF resulting from different overdose patterns are reported. METHODS Using prospectively defined criteria, we have analysed the impact of overdose pattern upon outcome in a cohort of 938 acute severe liver injury patients admitted to the Scottish Liver Transplantation Unit. RESULTS Between 1992 and 2008, 663 patients were admitted with paracetamol-induced acute severe liver injury. Of these patients, 500 (75.4%) had taken an intentional paracetamol overdose, whilst 110 (16.6%) had taken an unintentional overdose. No clear overdose pattern could be determined in 53 (8.0%). Unintentional overdose patients were significantly older, more likely to abuse alcohol, and more commonly overdosed on compound narcotic/paracetamol analgesics compared with intentional overdose patients. Unintentional overdoses had significantly lower admission paracetamol and alanine aminotransferase concentrations compared with intentional overdoses. However, unintentional overdoses had greater organ dysfunction at admission, and subsequently higher mortality (unintentional 42/110 (38.2%), intentional 128/500 (25.6%), P < 0.001). The King's College poor prognostic criteria had reduced sensitivity in unintentional overdoses (77.8%, 95% confidence intervals (CI) 62.9, 88.8) compared with intentional overdoses (89.9%, 95% CI 83.4, 94.5). Unintentional overdose was independently predictive of death or liver transplantation on multivariate analysis (odds ratio 1.91 (95% CI 1.07, 3.43), P= 0.032). CONCLUSIONS Unintentional paracetamol overdose is associated with increased mortality compared with intentional paracetamol overdose, despite lower admission paracetamol concentrations. Alternative prognostic criteria may be required for unintentional paracetamol overdoses. PMID:21219409

To explore the association between types of unintentional injuries and influential factors among rural rear pupils. The multistage stratified sampling method was used to select the study participant and thus 594 rural pupils were sampled, 292 rear pupils were confirmed and measured with unintentional injuries and influential factors of rural rear pupils scale. Binary logistic regression analysis indicate that the risk facts related to unintentional injury were left-behind status (OR = 2.68, 95% CI 1.06-6.79), gender (OR = 5.12, 95% C2.68-9.79) and surrounding environment (OR = 3.44, 95% CI 1.37-8.70). Correspondence analysis showed living with father, middle personality and low age were related possibly with traffic accident injury. Living with grandparents, extrovert personality and elder pupils were related possibly with unintentional falls injury. Living with mother, introvert personality and middle-age pupils were related possibly with animmal injury. The personality, ages and guardian types of rural rear pupils are correlated with types of unintentional injuries.

Unintentional Exposure to Online Sexual Content and Sexual Behavior Intentions Among College Students in China.

PubMed

Zhang, Jingwen; Jemmott, John B

2015-07-01

This study examined the relations of unintentional exposure to Internet sexual content to intentions for sex and condom use and potential mediators of these relations, including attitudes, norms, and self-efficacy, among college students in China. A sample of 524 Chinese college students completed an online questionnaire. Mediation path analyses were conducted to test the theory of planned behavior as a model of the relations between unintentional exposure and intentions to have sex and use condoms. On average, students reported being unintentionally exposed to Internet sexual content about 3 to 4 times during the past month. Unintentional exposure was indirectly associated with intention to have sex, mediated through descriptive and injunctive norms. Descriptive norm was a stronger mediator for females than males. In contrast, unintentional exposure was unrelated to condom-use intention and mediators. The theory of planned behavior provides a model for the development of Internet-based interventions with these students. © 2014 APJPH.

Complete unconscious control: Using (in)action primes to demonstrate completely unconscious activation of inhibitory control mechanisms

PubMed Central

Hepler, Justin; Albarracin, Dolores

2018-01-01

Although robust evidence indicates that action initiation can occur unconsciously and unintentionally, the literature on action inhibition suggests that inhibition requires both conscious thought and intentionality. In prior research demonstrating automatic inhibition in response to unconsciously processed stimuli, the unconscious stimuli had previously been consciously associated with an inhibitory response within the context of the experiment, and participants had consciously formed a goal to activate inhibition processes when presented with the stimuli (because task instructions required participants to engage in inhibition when the stimuli occurred). Therefore, prior work suggests that some amount of conscious thought and intentionality are required for inhibitory control. In the present research, we recorded event-related potentials during two go/no-go experiments in which participants were subliminally primed with general action/inaction concepts that had never been consciously associated with task-specific responses. We provide the first demonstration that inhibitory control processes can be modulated completely unconsciously and unintentionally. PMID:23747649

Chan, Derwin King Chung; Keatley, David A; Tang, Tracy C W; Dimmock, James A; Hagger, Martin S

2018-03-01

This preliminary study examined whether implicit doping attitude, explicit doping attitude, or both, predicted athletes' vigilance towards unintentional doping. A cross-sectional correlational design. Australian athletes (N=143;M age =18.13, SD=4.63) completed measures of implicit doping attitude (brief single-category implicit association test), explicit doping attitude (Performance Enhancement Attitude Scale), avoidance of unintentional doping (Self-Reported Treatment Adherence Scale), and behavioural vigilance task of unintentional doping (reading the ingredients of an unfamiliar food product). Positive implicit doping attitude and explicit doping attitude were negatively related to athletes' likelihood of reading the ingredients table of an unfamiliar food product, and positively related to athletes' vigilance towards unintentional doping. Neither attitude measures predicted avoidance of unintentional doping. Overall, the magnitude of associations by implicit doping attitude appeared to be stronger than that of explicit doping attitude. Athletes with positive implicit and explicit doping attitudes were less likely to read the ingredients table of an unknown food product, but were more likely to be aware of the possible presence of banned substances in a certain food product. Implicit doping attitude appeared to explain athletes' behavioural response to the avoidance of unintentional doping beyond variance explained by explicit doping attitude.

Vividness in judgements of guilt.

PubMed

Bensi, L; Nori, R; Strazzari, E; Giusberti, F

2003-12-01

This study investigated the vividness variable in legal decision-making. It was hypothesised that different verdicts regarding the same legal case can be obtained by simply varying the vividness of phrases, without changing any probative element. 53 participants read Original (26) or Vivid (27) versions of testimonies to a homicide case, then made a decision as to the defendant's guilt. Results support the hypothesis: participants' judgements significantly differ between the two conditions; that is, participants who read the Original version consider the homicide as unintentional while participants who read the Vivid one are not able to choose between intentional or unintentional homicide. Therefore we can infer that vividness influenced the process by which guilt is attributed.

Laugsand, Lars Erik; Strand, Linn B.; Vatten, Lars J.; Janszky, Imre; Bjørngaard, Johan Håkon

2014-01-01

Study Objectives: To assess the association between insomnia symptoms and risk of fatal unintentional injuries. Design: Population-based prospective cohort study with a mean follow-up of 14 y, linking health survey data with information on insomnia symptoms to the National Cause of Death Registry. Setting: Nord-Trøndelag County, Norway. Participants: A total of 54,399 men and women 20-89 y of age who participated in the Nord-Trøndelag Health Study between 1995 and 1997. Interventions: N/A. Measurements and results: There were 277 unintentional fatal injuries, including 57 fatal motor vehicle injuries during follow-up. There was a dose-dependent association between the number of insomnia symptoms and risk of unintentional fatal injuries (P for trend 0.001) and fatal motor vehicle injuries (P for trend 0.023), respectively. The proportion of unintentional fatal injuries cases that could have been prevented in the absence of difficulties initiating sleep, difficulties maintaining sleep, and having a feeling of nonrestorative sleep were 8%, 9%, and 8%, respectively. The corresponding estimates for motor vehicle injuries were 34%, 11%, and 10%. Conclusion: Insomnia is a major contributor to both unintentional fatal injuries in general as well as fatal motor vehicle injuries. Increasing public health awareness about insomnia and identifying persons with insomnia may be important in preventing unintentional fatal injuries.

The purpose of this study was to explore the epidemiological features of common unintentional injury-related behaviours and to identify possible factors that lead to these unsafe behaviours among adolescents. A representative sample of 10,806 students was recruited from 77 schools by using the two-stage stratified random sampling method. All participants took a self-administered questionnaires and data were analysed to estimate the prevalence of unintentional injury-related behaviours and to identify the influential factors for these behaviours. The prevalence of unsafe swimming, jaywalking, illegal bicycling and not wearing a seat belt was 6.35%, 33.08%, 18.10% and 15.73%, respectively. The proportion of students who had two, three or four unintentional injury-related behaviours was 14.59%, 4.27% and 0.57%, respectively. Multiple regression analysis showed that male adolescents, living in an urban area and attending a vocational-technical school might contribute to the occurrence of four unintentional injury-related behaviours. In addition, the marital status of parents and father with a college degree or above were negatively associated with the adolescent's behaviour of not wearing a seat belt. Considering diverse epidemiological characteristics of unintentional injury-related behaviours among adolescents, targeted interventions such as enhancing self-protection capabilities and strengthening safety consciousness by family, school and related departments should be implemented to lower the occurrence of unintentional injury-related behaviours.

The thickness design of unintentionally doped GaN interlayer matched with background doping level for InGaN-based laser diodes

In order to reduce the internal optical loss of InGaN laser diodes, an unintentionally doped GaN (u-GaN) interlayer is inserted between InGaN/GaN multiple quantum well active region and Al{sub 0.2}Ga{sub 0.8}N electron blocking layer. The thickness design of u-GaN interlayer matching up with background doping level for improving laser performance is studied. It is found that a suitably chosen u-GaN interlayer can well modulate the optical absorption loss and optical confinement factor. However, if the value of background doping concentration of u-GaN interlayer is too large, the output light power may decrease. The analysis of energy band diagram of amore » LD structure with 100 nm u-GaN interlayer shows that the width of n-side depletion region decreases when the background concentration increases, and may become even too small to cover whole MQW, resulting in a serious decrease of the output light power. It means that a suitable interlayer thickness design matching with the background doping level of u-GaN interlayer is significant for InGaN-based laser diodes.« less

Enhancing Electromagnetic Side-Channel Analysis in an Operational Environment

NASA Astrophysics Data System (ADS)

Montminy, David P.

Side-channel attacks exploit the unintentional emissions from cryptographic devices to determine the secret encryption key. This research identifies methods to make attacks demonstrated in an academic environment more operationally relevant. Algebraic cryptanalysis is used to reconcile redundant information extracted from side-channel attacks on the AES key schedule. A novel thresholding technique is used to select key byte guesses for a satisfiability solver resulting in a 97.5% success rate despite failing for 100% of attacks using standard methods. Two techniques are developed to compensate for differences in emissions from training and test devices dramatically improving the effectiveness of cross device template attacks. Mean and variance normalization improves same part number attack success rates from 65.1% to 100%, and increases the number of locations an attack can be performed by 226%. When normalization is combined with a novel technique to identify and filter signals in collected traces not related to the encryption operation, the number of traces required to perform a successful attack is reduced by 85.8% on average. Finally, software-defined radios are shown to be an effective low-cost method for collecting side-channel emissions in real-time, eliminating the need to modify or profile the target encryption device to gain precise timing information.

Unintentional Epinephrine Auto-injector Injuries: A National Poison Center Observational Study.

Anshien, Marco; Rose, S Rutherfoord; Wills, Brandon K

2016-11-24

Epinephrine is the only first-line therapeutic agent used to treat life-threatening anaphylaxis. Epinephrine auto-injectors are commonly carried by patients at risk for anaphylaxis, and reported cases of unintentional auto-injector injury have increased over the last decade. Modifications of existing designs and release of a new style of auto-injector are intended to reduce epinephrine auto-injector misuse. The aim of the study was to characterize reported cases of unintentional epinephrine auto-injector exposures from 2013 to 2014 and compare demographics, auto-injector model, and anatomical site of such exposures. The American Association of Poison Control Center's National Poison Data System was searched from January 1, 2013, to December 31, 2014, for cases of unintentional epinephrine auto-injector exposures. Anatomical site data were obtained from all cases reported to the Virginia Poison Center and participating regional poison center for Auvi-Q cases. A total of 6806 cases of unintentional epinephrine auto-injector exposures were reported to US Poison Centers in 2013 and 2014. Of these cases, 3933 occurred with EpiPen, 2829 with EpiPen Jr, 44 with Auvi-Q, and no case reported of Adrenaclick. The most common site of unintentional injection for traditional epinephrine auto-injectors was the digit or thumb, with 58% of cases for EpiPen and 39% of cases with EpiPen Jr. With Auvi-Q, the most common site was the leg (78% of cases). The number of unintentional epinephrine auto-injector cases reported to American Poison Centers in 2013-2014 has increased compared with previous data. Most EpiPen exposures were in the digits, whereas Auvi-Q was most frequently in the leg. Because of the limitations of Poison Center data, more research is needed to identify incidence of unintentional exposures and the effectiveness of epinephrine auto-injector redesign.

It has been suggested that health risks are affected by geographical area, but there are few studies on contextual effects using multilevel analysis, especially regarding unintentional injury. This study investigated trends in unintentional injury hospitalization rates over the past decade in Korea, and also examined community-level risk factors while controlling for individual-level factors. Using data from the 2004 to 2013 Korea National Hospital Discharge Survey (KNHDS), trends in age-adjusted injury hospitalization rate were conducted using the Joinpoint Regression Program. Based on the 2013 KNHDS, we collected community-level factors by linking various data sources and selected dominant factors related to injury hospitalization through a stepwise method. Multilevel analysis was performed to assess the community-level factors while controlling for individual-level factors. In 2004, the age-adjusted unintentional injury hospitalization rate was 1570.1 per 100,000 population and increased to 1887.1 per 100,000 population in 2013. The average annual percent change in rate of hospitalizations due to unintentional injury was 2.31% (95% confidence interval: 1.8-2.9). It was somewhat higher for females than for males (3.25% vs. 1.64%, respectively). Both community- and individual-level factors were found to significantly influence unintentional injury hospitalization risk. As community-level risk factors, finance utilization capacity of the local government and neighborhood socioeconomic status, were independently associated with unintentional injury hospitalization after controlling for individual-level factors, and accounted for 19.9% of community-level variation in unintentional injury hospitalization. Regional differences must be considered when creating policies and interventions. Further studies are required to evaluate specific factors related to injury mechanism.

An increased risk of unintentional injuries among individuals with disability has been reported in many studies, yet quantitative syntheses of findings from previous studies have not been done. We conducted a systematic review and meta-analysis to characterize the relationship between pre-existing disability and unintentional injuries. We searched 14 electronic databases to identify original research published between Jan 1, 1990 and Feb 28, 2013. Included studies reported the odds ratio (OR) or relative risk (RR) of unintentional injuries in adults 18+ years of age with pre-existing disabilities compared with adults without disabilities. Twenty six eligible studies were included covering 54,586 individuals with disabilities. We conducted quality assessments and then analyzed the pooled effects using random-effect models. The pooled OR of unintentional injuries was 1.77 (95% CI 1.51-2.07) for all studies in individuals with disabilities compared with individuals without disabilities. The pooled ORs were 1.87 (95% CI 1.52-2.30) for overall unintentional injuries, 1.64 (95% CI 1.39-1.94) for falls-related injuries, 1.62 (95% CI 1.24-2.13) for occupational injuries, and 1.91 (95% CI 1.59-2.30) for non-occupational injuries. Compared with adults without disabilities, individuals with disabilities are at a significantly higher risk of unintentional injuries. Evidence about the association between cognitive disabilities and unintentional injuries is weak. Future researchers are encouraged to use International Classification of Functioning, Disability and Health (ICF) to classify disability and use rigorous evaluation methods to assess and implement the most appropriate injury prevention efforts to mitigate the risks identified.

2017-01-01

Objective: To determine the rate and differential contribution of heading vs unintentional head impacts (e.g., head to head, goal post) to CNS symptoms in adult amateur soccer players. Methods: Amateur soccer players completed baseline and serial on-line 2-week recall questionnaires (HeadCount) and reported (1) soccer practice and games, (2) heading and unintentional soccer head trauma, and (3) frequency and severity (mild to very severe) of CNS symptoms. For analysis, CNS symptoms were affirmed if one or more moderate, severe, or very severe episodes were reported in a 2-week period. Repeated measures logistic regression was used to assess if 2-week heading exposure (i.e., 4 quartiles) or unintentional head impacts (i.e., 0, 1, 2+) were associated with CNS symptoms. Results: A total of 222 soccer players (79% male) completed 470 HeadCount questionnaires. Mean (median) heading/2 weeks was 44 (18) for men and 27 (9.5) for women. One or more unintentional head impacts were reported by 37% of men and 43% of women. Heading-related symptoms were reported in 20% (93 out of 470) of the HeadCounts. Heading in the highest quartile was significantly associated with CNS symptoms (odds ratio [OR] 3.17, 95% confidence interval [CI] 1.57–6.37) when controlling for unintentional exposure. Those with 2+ unintentional exposures were at increased risk for CNS symptoms (OR 6.09, 95% CI 3.33–11.17) as were those with a single exposure (OR 2.98, 95% CI 1.69–5.26) when controlling for heading. Conclusions: Intentional (i.e., heading) and unintentional head impacts are each independently associated with moderate to very severe CNS symptoms. PMID:28148633

On the Necessity of Distinguishing Between Unintentional and Intentional Mind Wandering.

PubMed

Seli, Paul; Risko, Evan F; Smilek, Daniel

2016-05-01

In recent years, there has been an enormous increase in the number of studies examining mind wandering. Although participants' reports of mind wandering are often assumed to largely reflect spontaneous, unintentional thoughts, many researchers' conceptualizations of mind wandering have left open the possibility that at least some of these reports reflect deliberate, intentional thought. Critically, however, in most investigations on the topic, researchers have not separately assessed each type of mind wandering; instead, they have measured mind wandering as a unitary construct, thereby conflating intentional and unintentional types. We report the first compelling evidence that an experimental manipulation can have qualitatively different effects on intentional and unintentional types of mind wandering. This result provides clear evidence that researchers interested in understanding mind wandering need to consider the distinction between unintentional and intentional occurrences of this phenomenon. © The Author(s) 2016.

Intelligence in early adulthood and subsequent risk of unintentional injury over two decades: cohort study of 1,109,475 Swedish men

PubMed Central

Whitley, Elise; Batty, G. David; Gale, Catharine R.; Deary, Ian J.; Tynelius, Per; Rasmussen, Finn

2014-01-01

Background There is growing evidence of an inverse association between intelligence (IQ) and unintentional injuries. Methods Analyses are based on a cohort of 1,109,475 Swedish men with IQ measured in early adulthood. Men were followed-up for an average 24 years and hospital admissions for unintentional injury were recorded. Results 198,133 (17.9%) men had at least one hospital admission for any unintentional injury during follow-up. The most common cause of unintentional injury was falling, followed by road accidents, poisoning, fire and drowning. In addition, 14,637 (1.3%) men had at least one admission for complications of medical care. After adjusting for confounding variables, lower IQ scores were associated with an elevated risk of any unintentional injury (Hazard ratio (95% confidence interval) per standard deviation decrease in IQ: 1.15 (1.14, 1.15)), and of cause-specific injuries other than drowning (poisoning (1.53 (1.49, 1.57)), fire (1.36 (1.31, 1.41)), road traffic accidents (1.25 (1.23, 1.26)), medical complications (1.20 (1.18, 1.22)), and falling (1.17 (1.16, 1.18)). These gradients were stepwise across the full IQ range. Conclusions Low IQ scores in early adulthood were associated with a subsequently increased risk of unintentional injury. A greater understanding of mechanisms underlying these associations may provide opportunities and strategies for prevention. PMID:19955099

Practical Insight to Monitor Home NIV in COPD Patients.

PubMed

Arnal, Jean-Michel; Texereau, Joëlle; Garnero, Aude

2017-08-01

Home noninvasive ventilation (NIV) is used in COPD patients with concomitant chronic hypercapnic respiratory failure in order to correct nocturnal hypoventilation and improve sleep quality, quality of life, and survival. Monitoring of home NIV is needed to assess the effectiveness of ventilation and adherence to therapy, resolve potential adverse effects, reinforce patient knowledge, provide maintenance of the equipment, and readjust the ventilator settings according to the changing condition of the patient. Clinical monitoring is very informative. Anamnesis focuses on the improvement of nocturnal hypoventilation symptoms, sleep quality, and side effects of NIV. Side effects are major cause of intolerance. Screening side effects leads to modification of interface, gas humidification, or ventilator settings. Home care providers maintain ventilator and interface and educate patients for correct use. However, patient's education should be supervised by specialized clinicians. Blood gas measurement shows a significant decrease in PaCO 2 when NIV is efficient. Analysis of ventilator data is very useful to assess daily use, unintentional leaks, upper airway obstruction, and patient ventilator synchrony. Nocturnal oximetry and capnography are additional monitoring tools to assess the impact of NIV on gas exchanges. In the near future, telemonitoring will reinforce and change the organization of home NIV for COPD patients.

British Muslims and the UK government's 'war on terror' within: evidence of a clash of civilizations or emergent de-civilizing processes?

PubMed

Vertigans, Stephen

2010-03-01

In the immediate aftermath of the September 2001 attacks on America, defending civilization was quickly established at the core of the 'war on terror'. Unintentionally or otherwise this incorporation of civilization connected with Samuel Huntington's 'Clash of Civilizations' thesis. Within the 'war on terror' the dark side of counterterrorism has become apparent through international practices like extrajudicial killing, extraordinary rendition and torture. The impact of Western governments' policies upon their indigenous Muslim populations has also been problematic but social and political analysis has been relatively limited. This paper seeks to help address the scarcity of sociological contributions. Hidden costs of the UK government's attempts to utilize violence and enhance social constraints within the nation-state are identified. It is argued that although counterterrorism strategies are contributing to a self-fulfilling spiral of hatred that could be considered evidence in support of the 'Clash of Civilizations', the thesis is unhelpful when trying to grasp the underlying processes. Instead the paper draws upon Norbert Elias's application of the concepts of 'civilizing' and 'de-civilizing' to help improve levels of understanding about the processes and consequences of particular Muslim communities being targeted by security forces. The paper concludes with an exploration of the majority of the population's acquiescence and willingness to accept restraints upon Muslims in order to safeguard their own security.

The crashes of four hijacked commercial planes on September 11, 2001, and the repeated televised images of the consequent collapse of the World Trade Center and one side of the Pentagon will inevitably change people's perceptions of the mortality risks to people on the ground from crashing airplanes. Goldstein and colleagues were the first to quantify the risk for Americans of being killed on the ground from a crashing airplane for unintentional events, providing average point estimates of 6 in a hundred million for annual risk and 4.2 in a million for lifetime risk. They noted that the lifetime risk result exceeded the commonly used risk management threshold of 1 in a million, and suggested that the risk to "groundlings" could be a useful risk communication tool because (a) it is a man-made risk (b) arising from economic activities (c) from which the victims derive no benefit and (d) exposure to which the victims cannot control. Their results have been used in risk communication. This analysis provides updated estimates of groundling fatality risks from unintentional crashes using more recent data and a geographical information system approach to modeling the population around airports. The results suggest that the average annual risk is now 1.2 in a hundred million and the lifetime risk is now 9 in ten million (below the risk management threshold). Analysis of the variability and uncertainty of this estimate, however, suggests that the exposure to groundling fatality risk varies by about a factor of approximately 100 in the spatial dimension of distance to an airport, with the risk declining rapidly outside the first 2 miles around an airport. We believe that the risk to groundlings from crashing airplanes is more useful in the context of risk communication when information about variability and uncertainty in the risk estimates is characterized, but we suspect that recent events will alter its utility in risk communication.

Abstract Globalization increases the opportunities for unintentionally introduced invasive alien species, especially for insects, and most of these species could damage ecosystems and cause economic loss in China. In this study, we analyzed drivers of the distribution of unintentionally introduced invasive alien insects. Based on the number of unintentionally introduced invasive alien insects and their presence/absence records in each province in mainland China, regression trees were built to elucidate the roles of environmental and anthropogenic factors on the number distribution and similarity of species composition of these insects. Classification and regression trees indicated climatic suitability (the mean temperature in January) and human economic activity (sum of total freight) are primary drivers for the number distribution pattern of unintentionally introduced invasive alien insects at provincial scale, while only environmental factors (the mean January temperature, the annual precipitation and the areas of provinces) significantly affect the similarity of them based on the multivariate regression trees.

Epidemiologic features of unintentional injuries among children in rural China are unknown. Using a stratified sampling method, we conducted a retrospective study of injury reports over a year-long period. Structured oral questionnaires were administered to parents of 2551 children ages 0 to 14. The annual incidence of unintentional injuries was 15.6%, with boys (16.7%) having a slightly higher rate than girls (14.5%; p greater than .05). The four leading causes of injury for both genders were falls (5.1% annual incidence), burns (2.9%), animal-related injuries (1.7%), and traffic injuries (1.6%). Unintentional injuries have substantial negative effects on children and their families. In rural PuCheng, China, the incidence of unintentional injury among children is extremely high compared to other regions of the world. The types of injuries incurred are somewhat different from those reported in other geographic areas. Injury prevention programs targeting the issues specific to this region, and similar rural regions of China, are needed.

According to the World Health Organization, unintentional injuries were responsible for over 3.9 million deaths and over 138 million disability-adjusted life-years in 2004, with over 90% of those occurring in low- and middle-income countries (LMIC). This paper utilizes the year 2004 World Health Organization Global Burden of Disease Study estimates to illustrate the global and regional burden of unintentional injuries and injury rates, stratified by cause, region, age, and gender. The worldwide rate of unintentional injuries is 61 per 100,000 population per year. Overall, road traffic injuries make up the largest proportion of unintentional injury deaths (33%). When standardized per 100,000 population, the death rate is nearly double in LMIC versus high-income countries (65 vs. 35 per 100,000), and the rate of disability-adjusted life-years is more than triple in LMIC (2,398 vs. 774 per 100,000). This paper calls for more action around 5 core areas that need research investments and capacity development, particularly in LMIC: 1) improving injury data collection, 2) defining the epidemiology of unintentional injuries, 3) estimating the costs of injuries, 4) understanding public perceptions about injury causation, and 5) engaging with policy makers to improve injury prevention and control.

To investigate the current status on knowledge for unintentional injury and risky behavior among school-age children in Changsha, China, and to provide scientific evidence for the preventive strategies.
 A cross-sectional study was conducted on 866 students who were between 6 and 12 years old in Changsha. Two primary schools were selected by stratified cluster random sampling from all primary schools of Changsha city to collect the information regarding knowledge for unintentional injury and risky behavior occurring in the 6-month period before the survey.
 The mean score for knowledge of unintentional injury was 11.83±2.38. The levels of knowledge for unintentional injury differed significantly in child's age, parents' education background and child's injury history (P<0.05). The child's knowledge level was correlated with child's age, mother's education, child's injury history. The mean score for risky behavior was 17.61±10.35. The levels of risky behavior differed significantly in child's gender, father's age to have the child, parents' marriage status, whom does/do child live with, child's injury history and medical history since the birthday (P<0.05). There was a linear regression relationship between risky behavior and child's injury history, parents' marriage status, child's gender. There was no significant correlation between knowledge and risky behavior (P>0.05).
 It is a common phenomenon in school-age children who are lack of the knowledge for unintentional injury and risky behavior. This study provides useful information on the risk factors for unintentional injury and risky behavior, which would be significant for prevention program.

Drug overdose mortality is a major public health concern in the United States, with prescription opioids contributing substantially to recent increases in drug overdose deaths. Compared to unintentional drug overdose deaths, relatively little data describes intentional self-inflicted drug overdose deaths (i.e., suicide by drug overdose). The aim of this study was to examine the characteristics of self-inflicted drug overdose deaths, overall and in comparison to unintentional drug overdose deaths. We linked vital statistics, prescription drug monitoring program, and toxicology data for self-inflicted and unintentional drug overdose deaths among North Carolina residents in 2012. Most self-inflicted (79.2%) and unintentional (75.6%) drug overdose decedents had a prescription for a controlled substance within one year of death. Toxicology results revealed that antidepressants contributed to a significantly higher percent of self-inflicted compared to unintentional drug overdose deaths (45.0% vs. 8.1%). Among deaths in which commonly prescribed opioids (oxycodone, hydrocodone) or benzodiazepines (alprazolam, clonazepam) contributed to death, a significantly higher percent of self-inflicted drug overdose decedents had a prescription for the substance within 30days of death compared to unintentional drug overdose decedents. The results highlight the use of prescription opioids, benzodiazepines, and antidepressants among self-inflicted drug overdose decedents. Importantly, the results indicate that self-inflicted drug overdose decedents were more likely than unintentional drug overdose decedents to have potential contact with the health care system in the weeks preceding death, offering an opportunity for professionals to identify and intervene on risk factors or signs of distress and potential for self-harm.

Daufanamae, Barbara U; Franklin, Richard C; Eagers, Jackie

2016-01-01

Unintentional injuries (injuries for which there is no evidence of a predetermined intent) are one of the leading causes of death worldwide, particularly in low- and middle-income countries (LMICs). Although evidence demonstrates unintentional injuries are preventable it is a public health challenge for many LMICs such as the Solomon Islands. Occupational therapists are well placed to contribute to injury prevention, as they have specialised skills to analyse the accessibility and safety of the environments within which people conduct their daily occupations. While the role of occupational therapy in unintentional injury prevention is well known in high-income countries, it is unfamiliar in LMICs, especially in the Solomon Islands. This integrative review aimed to explore the incidence of common unintentional injuries, and the burden in the Solomon Islands; and explore the potential role of occupational therapy in unintentional injury prevention in the Solomon Islands, based on current activities in LMICs. Articles were reviewed from six databases (Medline, CINAHL, OTDBase, OT Seeker, Scopus and PsychInfo). Five articles met the inclusion criteria for the first objective and 15 articles met the inclusion criteria for the second objective. These articles were thematically analysed where themes and codes associated with the research objectives were extracted and analysed. Unintentional injuries in the Solomon Islands reported in the literature included ocular trauma, falls from fruit trees and coconut palms, and road traffic crashes. Burden of injury reported was mostly associated with loss of productivity. Occupational therapists undertook rehabilitative, biomechanical, neurodevelopmental and educational roles in LMIC, focusing on tertiary and secondary injury prevention. This integrative review suggests that there is limited information regarding injury in the Solomon Islands. However, evidence is available in LMICs to suggest that occupational therapy services can play a potential significant role in unintentional injury prevention, demonstrating a need for establishing injury prevention within the occupational therapy role in the Solomon Islands.

Homeless people have elevated mortality, especially due to external causes. We aimed to examine suicide and unintentional injury mortality levels and identify predictors in the homeless population. A nationwide, register-based cohort study of homeless people aged 16 years and older was carried out using the Danish Homeless Register, 1999-2008. In all, 32 010 homeless people (70.5% men) were observed. For men, the mortality rate was 174.4 [95% confidence interval (CI) = 150.6-198.1] per 100 000 person-years for suicide and 463.3 (95% CI = 424.6-502.0) for unintentional injury. For women, the corresponding rates were 111.4 (95% CI = 81.7-141.1) for suicide and 241.4 (95% CI = 197.6-285.1) for unintentional injury. Schizophrenia spectrum, affective, personality and substance use disorders were strongly associated with increased risk of suicide; the highest risk estimates were found for schizophrenia spectrum disorders among both men [hazard ratio (HR) = 3.1, 95% CI = 2.0-4.9] and women (HR = 15.5, 95% CI = 4.5-54.0). Alcohol and drug use disorders were predictors of death by unintentional injury for both men and women, whereas schizophrenia spectrum disorders and personality disorders were only significant predictors among men; the highest risk estimates were found for drug use disorders among men (HR = 2.2, 95% CI = 1.8-2.8) and women (HR = 3.1, 95% CI = 1.8-5.4). A history of psychiatric admission and emergency room contact were predictors for dying by suicide and unintentional injury. People in the homeless shelter population with a history of a psychiatric disorder constitute a high-risk group regarding the elevated suicide and unintentional injury mortality.

Optimality and stability of intentional and unintentional actions: I. Origins of drifts in performance.

PubMed

Parsa, Behnoosh; Terekhov, Alexander; Zatsiorsky, Vladimir M; Latash, Mark L

2017-02-01

We address the nature of unintentional changes in performance in two papers. This first paper tested a hypothesis that unintentional changes in performance variables during continuous tasks without visual feedback are due to two processes. First, there is a drift of the referent coordinate for the salient performance variable toward the actual coordinate of the effector. Second, there is a drift toward minimum of a cost function. We tested this hypothesis in four-finger isometric pressing tasks that required the accurate production of a combination of total moment and total force with natural and modified finger involvement. Subjects performed accurate force-moment production tasks under visual feedback, and then visual feedback was removed for some or all of the salient variables. Analytical inverse optimization was used to compute a cost function. Without visual feedback, both force and moment drifted slowly toward lower absolute magnitudes. Over 15 s, the force drop could reach 20% of its initial magnitude while moment drop could reach 30% of its initial magnitude. Individual finger forces could show drifts toward both higher and lower forces. The cost function estimated using the analytical inverse optimization reduced its value as a consequence of the drift. We interpret the results within the framework of hierarchical control with referent spatial coordinates for salient variables at each level of the hierarchy combined with synergic control of salient variables. The force drift is discussed as a natural relaxation process toward states with lower potential energy in the physical (physiological) system involved in the task.

Injury is the leading cause of death for Canadians aged 1 to 44, occurring disproportionately across regions and communities. In the Inuit territory of Nunavut, for instance, unintentional injury rates are over three times the Canadian average. In this paper, we develop a framework for assessing vulnerability to injury and use it to identify and characterize the determinants of injuries on the land in Nunavut. We specifically examine unintentional injuries on the land (outside of hamlets) because of the importance of land-based activities to Inuit culture, health, and well-being. Semi-structured interviews (n = 45) were conducted in three communities that have varying rates of search and rescue (SAR), complemented by an analysis of SAR case data for the territory. We found that risk of land-based injuries is affected by socioeconomic status, Inuit traditional knowledge, community organizations, and territorial and national policies. Notably, by moving beyond common conceptualizations of unintentional injury, we are able to better assess root causes of unintentional injury and outline paths for prevention.

Unintentional injuries are a leading cause of death among children, especially in developing countries. Lack of reliable data regarding primary health care professionals’ role in childhood unintentional injury prevention hinders development of effective prevention strategies. A survey of 99 family physicians and nurses from 10 family health centres sought to develop insight into their knowledge, attitudes and practices regarding unintentional injury prevention for children <15 in Cairo, Egypt. Approximately 60% were familiar with the terms unintentional injuries and injury prevention. Falls and road traffic crashes were identified as primary causes of childhood injuries by 54.5%. While > 90% agreed injury prevention counselling (IPC) could be effective, only 50.5% provided IPC. Lack of time and educational materials were the leading barriers to provision of IPC (91.9%, 85.9%, respectively), while thinking counseling is not part of their clinical duties was the least perceived barrier (9.1%). There is a large disconnect between providers’ knowledge, attitudes and practices regarding IPC, more training and provision of counseling tools are essential for improving IPC by Egyptian medical providers.

Since wheat flour, a cause of food allergy, tends to disperse rapidly in air, it can unintentionally mix other foods during the sieving process. Our aim was to analyze the dispersal of wheat flour dust in air in order to prevent unintentional mixing. We measured particle size distribution of wheat flour, photographed the scattered flour for 60 seconds every 10 seconds after sieving through three types of flour sifter, constructed a velocity vector diagram of flour dust dispersal by each type of sifter, and measured the distance of wheat allergen dispersal over 20 minutes using a petri dish and immunochromatographic test. The particles were mainly 14.2μm and 60.4μm in diameter and settled at terminal velocities of about 8mm/s and 150mm/s, respectively. Wheat flour particles of more than 60μm (released in air by sifting) dropped mainly in the perpendicular direction, while particles of less than 30μm remained suspended and traveled 5m after sifting by all flour sifters. Our results suggested that wheat flour dust dispersed by sifting (regardless of sifter) could unintentionally mix other foods. To prevent contamination, it is necessary to control the flow of air or sift flour in a separate room.

Purpose This study explores the relationship between preschool attention deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), injury risk-taking behavior, and unintentional injury. Method Emergency department case control study of parent reported child behavior. Findings Children with ODD and ADHD had significantly more injury risk-taking behaviors (OR=7.68, 95% CI 2.25–26.25, OR 4.87, 95% CI 1.17–20.28 respectively) and injured children had a 17-fold increase in high risk-taking behaviors (OR 17.2, 95% CI 2.14–138.0). No significant association existed between ODD or ADHD and ED-treated unintentional injury. Implications Disruptive behavior disorders are not major contributors to ED-treated unintentional injury in preschool children. PMID:18809121

Photoreflectance measurements of unintentional impurity concentrations in undoped GaAs

Modulated photoreflectance is used to measure the unintentional impurity concentrations in undoped epitaxial GaAs. A photoreflectance signal above the band gap spreads with the unintentional impurity concentrations and shows well-defined Franz-Keldysh peaks whose separation provide a good measure of the current carrier concentrations. In samples less than 3-micron thick, a photoreflectance signal at the band edge contains a substrate-epilayer interface effect which precludes the analysis of the data by using the customary third derivative functional fits for low electric fields.

The Unintentional Procrastination Scale.

2017-01-01

Procrastination refers to the delay or postponement of a task or decision and is often conceptualised as a failure of self-regulation. Recent research has suggested that procrastination could be delineated into two domains: intentional and unintentional. In this two-study paper, we aimed to develop a measure of unintentional procrastination (named the Unintentional Procrastination Scale or the 'UPS') and test whether this would be a stronger marker of psychopathology than intentional and general procrastination. In Study 1, a community sample of 139 participants completed a questionnaire that consisted of several items pertaining to unintentional procrastination that had been derived from theory, previous research, and clinical experience. Responses were subjected to a principle components analysis and assessment of internal consistency. In Study 2, a community sample of 155 participants completed the newly developed scale, along with measures of general and intentional procrastination, metacognitions about procrastination, and negative affect. Data from the UPS were subjected to confirmatory factor analysis and revised accordingly. The UPS was then validated using correlation and regression analyses. The six-item UPS possesses construct and divergent validity and good internal consistency. The UPS appears to be a stronger marker of psychopathology than the pre-existing measures of procrastination used in this study. Results from the regression models suggest that both negative affect and metacognitions about procrastination differentiate between general, intentional, and unintentional procrastination. The UPS is brief, has good psychometric properties, and has strong associations with negative affect, suggesting it has value as a research and clinical tool.

2017-01-01

Topical corticosteroids are the standard of care in paediatric atopic dermatitis (pAD). However, messages that overstress possible side effects can have a negative impact on perceptions of safety and contribute to treatment non-adherence. The aim of this study was to assess general practitioners' (GPs') perception of the safety of topical corticosteroids in pAD treatment. Australian GPs participating in continuing professional development programs were assessed before an education session on pAD. Responses were recorded via an electronic survey. A total of 257 GPs were surveyed. More than one-third (40.7%) of the GPs instructed parents to apply topical corticosteroids for two weeks or less. Nearly half (47.7%) instructed parents to apply topical corticosteroids sparingly or with the smallest amount possible. Furthermore, nearly one-third (30.2%) reported skin atrophy as the most common side effect of topical corticosteroids. Advice to patients given by Australian GPs may carry unintentional risk messages contributing to treatment non‑adherence. Evidence-based information on the safety of topical corticosteroids is needed to empower GPs to improve treatment outcomes in pAD.

Unintentional injury is a leading cause of mortality and disability among young and old. While evidence about the effectiveness of interventions in reducing injuries is accumulating, reviews of this evidence frequently fail to include details of implementation processes. Our research, of which the work reported here formed a part, had two main objectives: (1) to identify evidence about the implementation of interventions aimed at reducing unintentional injuries amongst children and young people; and (2) to explore methods for systematically reviewing evidence on implementation. Existing systematic reviews of the effectiveness of interventions aiming to reduce unintentional injuries in children and young people formed the starting point for the work reported here. In summary, many of the published papers we identified contained little information on implementation processes and, even when these were discussed, the extent to which authors' claims were based on research evidence was unclear. On the basis of the studies we reviewed implementation data were insufficiently strong to provide a sound evidence base for practitioners and policymakers. Notwithstanding this, we identified valuable data about the context in which such initiatives are implemented and the type of factors that might impinge on implementation. This work has implications in three areas: (1) researchers with an interest in evidence-based public health could be encouraged to consider implementation issues in the design of intervention studies; (2) funding bodies could be encouraged to prioritise intervention studies using mixed methods that will enable researchers to consider effectiveness and implementation; (3) journal editors could work towards increasing the quality of reporting on implementation issues through the development of guidelines.

Effects of visual and verbal interaction on unintentional interpersonal coordination.

PubMed

Richardson, Michael J; Marsh, Kerry L; Schmidt, R C

2005-02-01

Previous research has demonstrated that people's movements can become unintentionally coordinated during interpersonal interaction. The current study sought to uncover the degree to which visual and verbal (conversation) interaction constrains and organizes the rhythmic limb movements of coactors. Two experiments were conducted in which pairs of participants completed an interpersonal puzzle task while swinging handheld pendulums with instructions that minimized intentional coordination but facilitated either visual or verbal interaction. Cross-spectral analysis revealed a higher degree of coordination for conditions in which the pairs were visually coupled. In contrast, verbal interaction alone was not found to provide a sufficient medium for unintentional coordination to occur, nor did it enhance the unintentional coordination that emerged during visual interaction. The results raise questions concerning differences between visual and verbal informational linkages during interaction and how these differences may affect interpersonal movement production and its coordination.

Unintentional firearm deaths: a comparison of other-inflicted and self-inflicted shootings.

2010-07-01

This study compares other-inflicted and self-inflicted unintentional firearm fatalities. Data come from the National Violent Death Reporting System, a new surveillance system from the Centers for Disease Control and Prevention. Data are currently available from 16 states and parts of California for various years 2003-2006. Of the 363 unintentional firearm fatalities, about half (49%) were other-inflicted, ranging from 78% of child (aged 0-14) deaths to 19% of older adult (aged 55+) deaths. In other-inflicted shooting deaths, the shooters were overwhelmingly young (81% under age 25). The shooters in the other-inflicted deaths were primarily friends (43%) or family (47%); brothers were the most common family shooter. To learn how to prevent unintentional injuries, it is critical to have information not only on the victim, but also on the person who inflicted the injury. Copyright 2010 Elsevier Ltd.

Unintentional Misreporting on Self-Report Measures of Sexually Aggressive Behavior: An Interview Study.

PubMed

Strang, Emily; Peterson, Zoё D

2017-10-01

The development of effective sexual aggression prevention programs for men relies on data garnered from studies using self-report measures of sexual aggression perpetration. However, few studies have focused on understanding and improving self-report measures of sexual aggression perpetration. The current study used open-ended interviews to explore the nature and frequency of community men's (N = 34) unintentional misreporting-including both overreporting and underreporting-on two self-report measures of sexual aggression perpetration: the Sexual Experiences Survey-Long Form Perpetration (SES-LFP; Koss et al., 2007) and the Sexual Strategies Scale (SSS; Strang, Peterson, Hill, & Heiman, 2013a). Item misinterpretation led to both overreporting and underreporting of sexual aggression, although underreporting was more common. Men's interpretations of items, decision-making processes, and reasons for producing discrepant reports across measures were analyzed and discussed. Results could help inform efforts to refine self-report measurement of men's sexual aggression.

Artificial reefs, in the Eastern Mediterranean (Cyprus,) became a popular and frequently used tool, in fisheries and biodiversity conservation management. Even though evaluation studies about the efficacy of artificial reefs are plentiful in the rest of the Mediterranean (Central and Western), in the Eastern Basin they are largely absent. As the Eastern part of the Mediterranean Sea is characterised by unique physical parameters, the necessity to study artificial reefs under these contrasting regimes increases. The epibenthic communities of two unintentional artificial reefs (modern shipwrecks) in Cyprus (Zenobia) and Lebanon (Alice-B) were evaluated in 2010. Both shipwrecks are at similar depth, type of sea bottom, made of the same material (steel) and were sunk approximately the same period of time. However, Alice-B shipwreck off the coast of Lebanon is constantly exposed to higher levels of nutrients than Zenobia in Cyprus. Significant dissimilarities were observed in the composition, percentage of benthic cover of predominant taxonomic groups and development of the epibenthic communities. Differences in physical and chemical parameters between sides lay mainly in the nutrient and thermal regimes affecting the shipwrecks and most likely bring about the differences in the observed community structure. The results of this study suggest that epibenthic communities could be highly impacted by eutrophication caused by anthropogenic activities, leading to less biodiverse communities dominated by specific species that are favoured by the eutrophic conditions.

The effect of heated vapor-phase acidification on organic carbon concentrations and isotopic values in geologic rock samples

Carbon signatures recorded in the modern and geologic rock record can give insight on the Earth's carbon cycle through time. This is especially true for organic carbon (OC), which can help us understand how the biosphere has evolved over Earth's history. However, carbon recorded in rocks is a combination of OC and inorganic carbon (IC) mostly in the form of carbonate minerals. To measure OC, IC must therefore first be removed through a process called "decarbonation." This is often done through a leaching process with hydrochloric acid (HCl). However, three well known problems exist for the decarbonation process: 1) Incomplete removal of IC, 2) Unintentional removal of OC, and 3) Addition of false carbon blank. Currently, vapor (gas) phase removal of OC is preferred to liquid phase treatment because it has been shown that OC is lost to solubilization during liquid phase acidification. Vapor phase treatment is largely thought to avoid the problem of OC loss, but this has not yet been rigorously investigated. This study investigates that assumption and shows that vapor phase treatment can cause unintentional OC loss. We show that vapor phase treatment must be sensitive to rock type and treatment length to produce robust OC isotopic measurements and concentrations.

Visual Benefits in Apparent Motion Displays: Automatically Driven Spatial and Temporal Anticipation Are Partially Dissociated

Many behaviourally relevant sensory events such as motion stimuli and speech have an intrinsic spatio-temporal structure. This will engage intentional and most likely unintentional (automatic) prediction mechanisms enhancing the perception of upcoming stimuli in the event stream. Here we sought to probe the anticipatory processes that are automatically driven by rhythmic input streams in terms of their spatial and temporal components. To this end, we employed an apparent visual motion paradigm testing the effects of pre-target motion on lateralized visual target discrimination. The motion stimuli either moved towards or away from peripheral target positions (valid vs. invalid spatial motion cueing) at a rhythmic or arrhythmic pace (valid vs. invalid temporal motion cueing). Crucially, we emphasized automatic motion-induced anticipatory processes by rendering the motion stimuli non-predictive of upcoming target position (by design) and task-irrelevant (by instruction), and by creating instead endogenous (orthogonal) expectations using symbolic cueing. Our data revealed that the apparent motion cues automatically engaged both spatial and temporal anticipatory processes, but that these processes were dissociated. We further found evidence for lateralisation of anticipatory temporal but not spatial processes. This indicates that distinct mechanisms may drive automatic spatial and temporal extrapolation of upcoming events from rhythmic event streams. This contrasts with previous findings that instead suggest an interaction between spatial and temporal attention processes when endogenously driven. Our results further highlight the need for isolating intentional from unintentional processes for better understanding the various anticipatory mechanisms engaged in processing behaviourally relevant stimuli with predictable spatio-temporal structure such as motion and speech.

Abstract Objective To estimate fall-related mortality by type of fall in India. Methods The authors analysed unintentional injury data from the ongoing Million Death Study from 2001–2003 using verbal autopsy and coding of all deaths in accordance with the International statistical classification of diseases and related health problems, tenth revision, in a nationally representative sample of 1.1 million homes throughout the country. Findings Falls accounted for 25% (2003/8023) of all deaths from unintentional injury and were the second leading cause of such deaths. An estimated 160 000 fall-related deaths occurred in India in 2005; of these, nearly 20 000 were in children aged 0–14 years. The unintentional-fall-related mortality rate (MR) per 100 000 population was 14.5 (99% confidence interval, CI: 13.7–15.4). Rates were similar for males and females at 14.9 (99% CI: 13.7–16.0) and 14.2 (99% CI: 13.1–15.4) per 100 000 population, respectively. People aged 70 years or older had the highest mortality rate from unintentional falls (MR: 271.2; 99% CI: 249.0–293.5), and the rate was higher among women (MR: 281; 99% CI: 249.7–311.3). Falls on the same level were the most common among older adults, whereas falls from heights were more common in younger age groups. Conclusion In India, unintentional falls are a major public health problem that disproportionately affects older women and children. The contexts in which these falls occur and the resulting morbidity and disability need to be better understood. In India there is an urgent need to develop, test and implement interventions aimed at preventing falls. PMID:22084511

Construction workers are exposed to a wide variety of health hazards such as poisoning at the construction sites. Various forms of poisoning incidents in construction workers have been reported. However, studies on methemoglobinemia caused by unintentional ingestion of antifreeze admixtures containing sodium nitrite at the construction sites have not been reported yet. The aim of this study was to evaluate life-threatening methemoglobinemia after unintentional ingestion of antifreeze admixtures containing sodium nitrite at the construction sites and describe similar incidents involving ingestion of antifreeze admixtures in Korea. Retrospective observational case series study on patients with methemoglobinemia after unintentional ingestion of antifreeze admixtures containing sodium nitrite admitted to the emergency department (ED) from January 1, 2010 to December 31, 2012 and cases reported to the Korea Occupational Safety and Health Agency (KOSHA) was performed. Results. Six victims were admitted to our ED. They had methemoglobin levels ranging from 32.4% to 71.5% and all of them recovered after receiving one (2 mg/kg) or two doses infusion of methylene blue. From the data of the KOSHA, six incidents that caused 27 victims were identified. Of 27 victims, five were included in the ED cases. For all incidents, antifreeze admixtures were not contained in their original containers and all new containers did not have a new label. All workers mistook antifreeze admixtures for water. Among the 28 victims included in this study, four died. Unintentional ingestion of antifreeze admixtures containing sodium nitrite at the construction sites can cause life-threatening methemoglobinemia. There is a need to store and label potentially hazardous materials properly to avoid unintentional ingestion at the construction sites.

Storage and disposal of medical cannabis among patients with cancer: Assessing the risk of diversion and unintentional digestion.

Increasingly more jurisdictions worldwide are legalizing medical cannabis. Major concerns related to such policies are that improper storage and disposal arrangements may lead to the diversion and unintentional digestion of cannabis. These concerns are particularly acute among patients with cancer because they take home medical cannabis for extended periods and have high rates of treatment termination and mortality shortly after the onset of treatment with medical cannabis. Therefore, leftover cannabis is potentially particularly prevalent, and potentially improperly stored, in households of current and deceased patients with cancer. The current study investigated the risk of medical cannabis diversion and unintentional digestion among oncology patients treated with medical cannabis and caregivers of recently deceased patients who were treated with medical cannabis. A total of 123 oncology patients treated with medical cannabis and 37 caregivers of deceased oncology patients treated with medical cannabis were interviewed regarding practices and the information received concerning the safe storage and disposal of medical cannabis, as well as experiences of theft, diversion, and unintentional digestion. High rates of suboptimal storage were reported and caregivers were found to be particularly unlikely to have received information regarding the safe storage and disposal of medical cannabis. Few incidences of theft, diversion, and unintentional digestion were reported. Oncologists and other health care providers have an important, yet unfilled, role to play with regard to educating patients and caregivers of the importance of the safe storage and disposal of medical cannabis. Interventions designed to alert patients treated with medical cannabis and their caregivers to the problem of diversion, along with strategies to limit it, have the potential to limit diversion and unintentional exposure to medical cannabis.

2017-01-01

A growing number of studies have reported age-related reductions in the frequency of mind wandering. Here, at both the trait (Study 1) and state (Study 2) levels, we re-examined this association while distinguishing between intentional (deliberate) and unintentional (spontaneous) mind wandering. Based on research demonstrating age-accompanied deficits in executive functioning, we expected to observe increases in unintentional mind wandering with increasing age. Moreover, because aging is associated with increased task motivation, we reasoned that older adults might be more engaged in their tasks, and hence, show a more pronounced decline in intentional mind wandering relative to young adults. In both studies, we found that older adults did indeed report lower rates of intentional mind wandering compared with young adults. However, contrary to our expectations, we also found that older adults reported lower rates of unintentional mind wandering (Studies 1 and 2). We discuss the implications of these findings for theories of age-related declines in mind wandering. PMID:28471215

Riegel, Barbara; Dickson, Victoria Vaughan

To explore factors contributing to intentional and unintentional medication nonadherence in adults with chronic heart failure (HF). Medication nonadherence is prevalent in HF but the factors contributing to it are not well understood. This secondary data analysis of qualitative data explored narrative accounts about medication adherence from four previous studies (N = 112). The Necessity-Concerns-Framework derived from the Common Sense Model (CSM) of Self-Regulation guided the interpretation of themes. In this diverse sample (39% Black, 6% Hispanic, 63% male; mean age 59 ± 15 years), 90% reported at least intermittent nonadherence. For many (60%), missing medication was unintentional but 27% reported intentional nonadherence. Four interconnected patterns of behavior emerged: 1) rarely nonadherent, 2) frequently nonadherent, 3) intentionally nonadherent, and 4) reformed nonadherent. Misperceptions about HF, beliefs, concerns, and contextual factors contributed to both intentional and unintentional nonadherence. Medication nonadherence is prevalent in HF and influenced by modifiable factors. Copyright © 2016 Elsevier Inc. All rights reserved.

Compared to heading, unintentional head impacts (e.g., elbow to head, head to head, head to goalpost) in soccer are more strongly related to risk of moderate to very severe Central Nervous System (CNS) symptoms. But, most head impacts associated with CNS symptoms that occur in soccer are mild and are more strongly related to heading. We tested for a differential relation of heading and unintentional head impacts with neuropsychological (NP) test performance. Active adult amateur soccer players were recruited in New York City and the surrounding areas for this repeated measures longitudinal study of individuals who were enrolled if they had 5+ years of soccer play and were active playing soccer 6+ months/year. All participants completed a baseline validated questionnaire ("HeadCount-2w"), reporting 2-week recall of soccer activity, heading and unintentional head impacts. In addition, participants also completed NP tests of verbal learning, verbal memory, psychomotor speed, attention, and working memory. Most participants also completed one or more identical follow-up protocols (i.e., HeadCount-2w and NP tests) at 3- to 6-month intervals over a 2-year period. Repeated measures General Estimating Equations (GEE) linear models were used to determine if variation in NP tests at each visit was related to variation in either heading or unintentional head impacts in the 2-week period before testing. 308 players (78% male) completed 741 HeadCount-2w. Mean (median) heading/2-weeks was 50 (17) for men and 26 (7) for women. Heading was significantly associated with poorer performance on psychomotor speed ( p  < 0.001) and attention ( p  = 0.02) tasks and was borderline significant with poorer performance on the working memory ( p  = 0.06) task. Unintentional head impacts were not significantly associated with any NP test. Results did not differ after excluding 22 HeadCount-2w with reported concussive or borderline concussive symptoms. Poorer NP test performance was consistently related to frequent heading during soccer practice and competition in the 2 weeks before testing. In contrast, unintentional head impacts incurred during soccer were not related to cognitive performance.

Introduction Poisoning, specifically unintentional poisoning, is a major public health problem in the United States (U.S.). Published literature that presents epidemiology of all forms of poisoning mortalities (i.e., unintentional, suicide, homicide) together is limited. This report presents data and summarizes the evidence on poisoning mortality by demographic and geographic characteristics to describe the burden of poisoning mortality and the differences among sub-populations in the U.S. for a 5-year period. Methods Using mortality data from the Center for Disease Control and Prevention's Web-based Injury Statistics Query and Reporting System, we presented the age-specific and age-adjusted unintentional and intentional (suicide, homicide) poisoning mortality rates by sex, age, race, and state of residence for the most recent years (2003–2007) of available data. Annual percentage changes in deaths and rates were calculated, and linear regression using natural log were used for time-trend analysis. Results There were 121,367 (rate=8.18 per 100,000) unintentional poisoning deaths. Overall, the unintentional poisoning mortality rate increased by 46.9%, from 6.7 per 100,000 in 2003 to 9.8 per100.000 in 2007, with the highest mortality rate among those aged 40–59 (rate=15.36), males (rate=11.02) and whites (rate=8.68). New Mexico (rate=18.2) had the highest rate. Unintentional poisoning mortality rate increased significantly among both sexes, and all racial groups except blacks (p<0.05 time-related trend for rate). Among a total of 29,469 (rate=1.97) suicidal poisoning deaths, the rate increased by 9.9%, from 1.9 per 100,000 in 2003 to 2.1 per 100,000 in 2007, with the highest rate among those aged 40–59 (rate=3.92), males (rate=2.20) and whites (rate=2.24). Nevada (rate=3.9) had the highest rate. Mortality rate increased significantly among females and whites only (p<0.05 time-related trend for rate). There were 463 (rate=0.03) homicidal poisoning deaths and the rate remained the same during 2003–2007. The highest rates were among aged 0–19 (rate=0.05), males (rate=0.04) and blacks (rate=0.06). Conclusion Prevention efforts for poisoning mortalities, especially unintentional poisoning, should be developed, implemented and strengthened. Differences exist in poisoning mortality by age, sex, location, and these findings underscore the urgency of addressing this public health burden as this epidemic continues to grow in the U.S. PMID:22900120

We examined the leading causes of unintentional injury and suicide mortality in adults across the urban-rural continuum. Injury mortality data were drawn from a representative cohort of 2,735,152 Canadians aged ≥ 25 years at baseline, who were followed for mortality from 1991 to 2001. We estimated hazard ratios and 95% confidence intervals for urban-rural continuum and cause-specific unintentional injury (i.e., motor vehicle, falls, poisoning, drowning, suffocation, and fire/burn) and suicide (i.e., hanging, poisoning, firearm, and jumping) mortality, adjusting for socioeconomic and demographic characteristics. Rates of unintentional injury mortality were elevated in less urbanized areas for both males and females. We found an urban-rural gradient for motor vehicle, drowning, and fire/burn deaths, but not for fall, poisoning, or suffocation deaths. Urban-rural differences in suicide risk were observed for males but not females. Declining urbanization was associated with higher risks of firearm suicides and lower risks of jumping suicides, but there was no apparent trend in hanging and poisoning suicides. Urban-rural gradients in adults were more pronounced for unintentional motor vehicle, drowning, and fire/burn deaths, as well as for firearm and jumping suicide deaths than for other causes of injury mortality. These results suggest that the degree of urbanization may be an important consideration in guiding prevention efforts for many causes of injury fatality.

Acetaminophen is the most involved active substance in both unintentional and intentional drug poisoning. However, its availability outside community pharmacies is being debated in France. We made, via a self-administered questionnaire, a prospective assessment of knowledge, use and acetaminophen overdose risk in patients consulting their general practitioner, in the Metz Métropole urban area, between May 2015 and February 2016. We estimated the prevalence of potential unintentional overdosage by capture-recapture method. Among 819 responding patients, only 17.9 % had a sufficient knowledge and 20.3 % were at risk for potential unintentional overdose. The risk was higher for patients aged over 55 years or belonging to socioprofessional categories of laborers and inactive. A good knowledge score was a protective factor for overdose risk (P<0.0001). The liver toxicity of acetaminophen was particularly unknown. The prevalence of potential unintentional acetaminophen overdose was estimated at 1 to2 % of the population. Proposing acetaminophen outside of pharmacies cannot be recommended in France in such conditions. Information campaigns are needed to limit the risk of unintentional overdose and its consequences on liver toxicity. Copyright © 2017 Société française de pharmacologie et de thérapeutique.

2009-11-01

Injury is a major global disease burden for the twenty-first century. There are, however, few studies of unintentional household injury in Asian urban settings where living environments are characterized by extremely compact, high-living-density, multistory apartments. This study investigated the association between nonfatal unintentional household injuries with the resident's sociodemographic attributes and household characteristics in Hong Kong, the city with the world's highest population density. A cross-sectional retrospective recall study was conducted in May 2007 using a random telephone survey with a modified Chinese version of the World Health Organization Injury and Violence instrument. The study sample included 1,001 noninstitutionalized Cantonese-speaking Hong Kong residents of all ages, including foreign live-in domestic helpers. Multivariate regression was conducted to identify risk factors for nonfatal unintentional injuries in Hong Kong. Among a predominantly adult sample, household size and time spent at home were not associated with nonfatal unintentional household injuries in the general population in Hong Kong. The multivariate analyses indicated that female gender, owners of private homes, lower square footage of living space per person, and those with slip prevention devices in the bathroom were significantly associated with household injuries. Injured and noninjured groups were found to have adopted different injury prevention strategies toward household injuries. The results identified potential target groups for household injury prevention programs.

Are “Anti-Aging Medicine” and “Successful Aging” Two Sides of the Same Coin? Views of Anti-Aging Practitioners

PubMed Central

2013-01-01

Objectives. This article analyzes data from interviews with anti-aging practitioners to evaluate how their descriptions of the work they do, their definitions of aging, and their goals for their patients intersect with gerontological views of “successful aging.” Method. Semistructured interviews were conducted with a sample of 31 anti-aging practitioners drawn from the directory of the American Academy for Anti-Aging Medicine. Results. Qualitative analysis of the transcripts demonstrate that practitioners’ descriptions of their goals, intentionally or unintentionally, mimic the dominant models of “successful aging.” These include lowered risk of disease and disability, maintenance of high levels of mental and physical function, and continuing social engagement. Yet, the means and modes of achieving these goals differ markedly between the two groups, as do the messages that each group puts forth in defending their positions. Discussion. Anti-aging practitioners’ adoption of the rhetoric of successful aging reflects the success of successful aging models in shaping popular conceptions of what aging is and an ethos of management and control over the aging process. The overlap between anti-aging and successful aging rhetoric also highlights some of the most problematic social, cultural, and economic consequences of efforts made to reconceptualize old age.

2015-01-01

Schizophrenia is a severe mental disorder that is highly characterized by social cognitive impairments. Most studies investigating these impairments focus on one specific social domain such as emotion recognition. However, in daily life, processing complex social situations relies on the combination of several social cognitive and affective processes simultaneously rather than one process alone. A modified version of the economically based Ultimatum Game was used to measure the interplay between fairness, intentionality, and emotion considerations during social decision-making. In this task, participants accept or reject fair and unfair monetary offers proposed intentionally or unintentionally by either angry, happy, neutral, or sad proposers. Behavioral data was collected from a group of schizophrenia patients (N = 35) and a group of healthy individuals (N = 30). Like healthy participants, schizophrenia patients differentiated between fair and unfair offers by rejecting unfair offers more compared to fair offers. However, overall patients did reject more fair offers, indicating that their construct of fairness operates within different margins. In both groups, intentional unfair offers were rejected more compared to unintentional ones, indicating a normal integration of intentionality considerations in schizophrenia. Importantly, healthy subjects also differentiated between proposers' emotion when rejecting unfair offers (more rejections from proposers depicting angry faces compared to proposers depicting, happy, neutral, or sad faces). Schizophrenia patients' decision behavior on the other hand, was not affected by the proposers' emotions. The current study thus shows that schizophrenia patients have specific problems with processing and integrating emotional information. Importantly, the finding that patients display normal fairness and intentionality considerations emphasizes preservation of central social cognitive processes in schizophrenia.

Women in agriculture: risks for occupational injury within the context of gendered role.

McCoy, C A; Carruth, A K; Reed, D B

2002-02-01

Women continue to make significant contributions to farming. Not only do women participate in the traditional roles of homemaker, caregiver, and wife, they also work side-by-side with their spouses in keeping the farm viable. More daughters are entering the farming business, either as partners with other family members or as independent operators. Each year since the United States Department of Agriculture began including gender in the Census of Agriculture, the percentage of women engaged in agriculture has increased, and women's participation in agriculture is increasing faster than in other business segments. This article examines the role of women in agriculture and how sociocultural, economic, and physical factors may affect women's exposure to injury-producing events and their knowledge and beliefs about injury prevention. To date, few studies have examined work-related unintentional injuries among farm women. Even less is known about the extent to which occupational risks are recognized when women seek medical care. Differences in size and stature, increased physical strain, and low maximal oxygen uptake may predispose women to ergonomic-related injuries. Limitations of current research and recommendations for future analyses are discussed.

Preventable medical errors in the operating room are most often caused by ineffective communication and suboptimal team dynamics. TeamSTEPPS is a government-funded, evidence-based program that provides tools and education to improve teamwork in medicine. The study hospital implemented TeamSTEPPS in the operating room and merged the program with a surgical safety checklist. Audits were performed to collect both quantitative and qualitative information on time out (brief) and debrief conversations, using a standardized audit tool. A total of 1610 audits over 6 months were performed by live auditors. Performance was sustained at desired levels or improved for all qualitative metrics using χ 2 and linear regression analyses. Additionally, the absolute number of wrong site/side/person surgery and unintentionally retained foreign body counts decreased after TeamSTEPPS implementation.

A 22-year-old female was diagnosed with a skeletal Class II, Division 2 malocclusion with Class II molar and canine relationships on both sides. The treatment plan included distalization of the maxillary first molars bilaterally followed by full fixed appliance therapy. For the maxillary molar distalization, an appliance in conjunction with a miniscrew anchorage system was designed. Two months later, the patient came to the clinic with complaints of pain in the maxillary right lateral incisor region. On intraoral examination, intraoral sinus tracts were detected in the maxillary right buccal sulcus and palate. A large radiolucent lesion with a well-defined margin around the root of the maxillary right lateral incisor was seen. Root canal treatment was performed on the maxillary right lateral incisor tooth. The root canal was filled with gutta-percha and AH Plus sealer, using a lateral compaction technique. The final restoration of the tooth was completed using composite, and the tooth was reviewed after 10 months. The tooth was asymptomatic and radiographically showed repair of the lesion. Healing was achieved without any need for further endodontic or surgical intervention. Key learning points • This case illustrates the need to take care with miniscrews when performing orthodontic treatment, especially when the miniscrews are in close proximity to root apices. • The periradicular lesion as a result of miniscrew damage was successfully treated with root canal treatment. © 2011 International Endodontic Journal.

This study was conducted to estimate the cumulative incidence rate (CIR) of unintentional injuries in Korean daily life and to describe the pattern of unintentional injuries. The study population was the people who used the National Health Insurance because of injuries (ICD code: S00-T98) during 2006. The stratified sample according to gender, age and the severity of injury (NISS, New Injury Severity Score) was randomly selected. The questions on the questionnaire were developed as a reference for an international classification tool (ICECI, International Classification of External Causes of Injury). The questions included the locations of injury, the mechanisms of injury and the results of injury. Moreover, we used age, gender, region and income variables for analysis. The CIR of unintentional injuries that occurred in daily life for 1 year per 100,000 persons was 17,606, and the CIR of severe injuries was 286. Many injuries were occurred at home (29.6%), public places (19.0%), school (13.7%) and near home (12.0%). The major mechanisms of injuries were slipping (48.8%), contact (14.0%), physical over-exertion (13.8%), and fall (6.6%). Infants and old aged people were vulnerable to injuries, and those who lived rural area and who were in a low income level were vulnerable too. We signified the risk groups and risk settings of unintentional injuries in Korean daily life. These results could contribute to establishing strategies for injury prevention and implementing these strategies.

Background Acute poisoning in children is a major preventable cause of morbidity and mortality in both developed and developing countries. However, there is a wide variation in patterns of poisoning and related risk factors across different geographic regions globally. This hospital based case-control study identifies the risk factors of acute unintentional poisoning among children aged 1−5 years of the rural community in a developing Asian country. Methods This hospital based case-control study included 600 children. Each group comprised three hundred children and all children were recruited at Anuradhapura Teaching Hospital, Sri Lanka, over two years (from February 2012 to January 2014). The two groups were compared to identify the effect of 23 proposed risk factors for unintentional poisoning using multivariate analysis in a binary logistic regression model. Results Multivariate analysis identified eight risk factors which were significantly associated with unintentional poisoning. The strongest risk factors were inadequate supervision (95% CI: 15.4–52.6), employed mother (95% CI: 2.9–17.5), parental concern of lack of family support (95% CI: 3.65–83.3), and unsafe storage of household poisons (95% CI: 1.5–4.9). Conclusions Since inadequate supervision, unsafe storage, and unsafe environment are the strongest risk factors for childhood unintentional poisoning, the effect of community education to enhance vigilance, safe storage, and assurance of safe environment should be evaluated.

Understanding the origin of unintentional doping in Ga 2 O 3 is key to increasing breakdown voltages of Ga 2 O 3 based power devices. Therefore, transport and capacitance spectroscopy studies have been performed to better understand the origin of unintentional doping in Ga 2 O 3 . Previously unobserved unintentional donors in commercially available [Formula: see text] Ga 2 O 3 substrates have been electrically characterized via temperature dependent Hall effect measurements up to 1000 K and found to have a donor energy of 110 meV. The existence of the unintentional donor is confirmed by temperature dependent admittance spectroscopy, with an activation energy of 131 meV determined via that technique, in agreement with Hall effect measurements. With the concentration of this donor determined to be in the mid to high 10 16  cm -3 range, elimination of this donor from the drift layer of Ga 2 O 3 power electronics devices will be key to pushing the limits of device performance. Indeed, analytical assessment of the specific on-resistance (R onsp ) and breakdown voltage of Schottky diodes containing the 110 meV donor indicates that incomplete ionization increases R onsp and decreases breakdown voltage as compared to Ga 2 O 3 Schottky diodes containing only the shallow donor. The reduced performance due to incomplete ionization occurs in addition to the usual tradeoff between R onsp and breakdown voltage.

Background: Falling asleep at work is receiving increasing attention as a cause of work accidents. Aims: To investigate which variables (related to work, lifestyle, or background) are related to the tendency to fall asleep unintentionally, either during work hours, or during leisure time. Methods: 5589 individuals (76% response rate) responded to a questionnaire. A multiple logistic regression analysis of the cross sectional data was used to estimate the risk of falling asleep. Results: The prevalence for falling asleep unintentionally at least once a month was 7.0% during work hours and 23.1% during leisure time. The risk of unintentional sleep at work was related to disturbed sleep, having shift work, and higher socioeconomic group. Being older, being a woman, and being a smoker were associated with a reduced risk of unintentionally falling asleep at work. Work demands, decision latitude at work, physical load, sedentary work, solitary work, extra work, and overtime work were not related to falling asleep at work. Removing "disturbed sleep" as a predictor did not change the odds ratios of the other predictors in any significant way. With respect to falling asleep during leisure time, disturbed sleep, snoring, high work demands, being a smoker, not exercising, and higher age (>45 years) became risk indicators. Conclusion: The risk of involuntary sleep at work is increased in connection with disturbed sleep but also with night work, socioeconomic group, low age, being a male, and being a non-smoker.

To examine the association between minor and major mental health impairment in late adolescence and death from suicide and unintentional injuries/accidents in men. In Norway, all men attend a compulsory military medical and psychological examination. We included 558 949 men aged 17-19 years at the time of military examination in 1980-1999 and followed them up for death from suicide and unintentional injuries/accidents until the end of 2013. We used Cox proportional hazard models to examine the association between the presence of minor and major mental health impairments at examination and death from suicide and unintentional injuries/accidents. Compared to men with no mental health impairment, those with minor mental health impairment was associated with an increased risk of death from suicide (adjusted HR (HR adj )=1.63, 95% CI 1.39 to 1.92), transport accidents (HR adj =1.33, 95% CI 1.09 to 1.63), accidental poisoning (HR adj =2.27, 95% CI 1.79 to 2.88) and other unintentional injuries/accidents (HR adj =1.54, 95% CI 1.17 to 2.02). In men with major mental health impairment, the risk of death from suicide and accidental poisoning was elevated two times (HR adj =2.29, 95% CI 1.85 to 2.85) and three times (HR adj =3.53, 95% CI 2.61 to 4.79), respectively. We found an increased risk of death from suicide and unintentional injuries/accidents in men who had minor and major mental health impairment at age 17-19 years.

Experience with several, previously unreported, intentional face-first immersion burns led us to evaluate the distribution of inflicted and unintentional immersion scald burns in a hospital series. (1) Authors' clinical and legal practices; (2) Burn center at regional Level 1 trauma hospital. : (1) Case series of face-first, inflicted immersion burn victims; (2) Consecutive hospitalized scald burn victims younger than 5 years old, 1/3/1996 to 3/25/2000. (1) Individual case reports; (2) Retrospective records review. Simple descriptive statistics, Fisher Exact test and t test. (1) Six cases of inflicted head and neck immersion injury are described. Four were tap water and 2 food/drink scalds. (2) 22/195 hospitalized victims had sustained immersion burns, 13 from tap water and 9 from other fluids. Six (46%) tap water immersions and no (0%) other immersions had inflicted injuries (P = 0.05). Two of the tap water immersions and one other source immersion included burning of the head and neck. Of these, one tap water immersion, but no other immersion, was inflicted. In no patients were head and neck injuries the sole or predominant site of scalding. In all, 9 children sustained inflicted scalds. Bilateral lower extremity tap water immersion scalds occurred in 100% (6/6) of abusive and 29% (2/7) of unintentional injuries (P = 0.02). Buttock and perineal injuries occurred in 67% (4/6) inflicted versus 29% (2/7) unintentional tap water immersion scalds (P = 0.28). Other fluids caused bilateral lower extremity immersion burns in 3/9 (33 %) unintentionally injured patients, but no abused children (NS). Craniofacial immersion injury, although seen by the authors in legal cases, is infrequent. It was present incidentally in one inflicted tap water burn in the consecutive hospital series. This series affirms the predominance of bilateral lower extremity burns in inflicted tap water immersions. Buttock/perineal immersions were more common with abuse than with unintentional injury.

2016-01-01

Unintentional injury is the fourth leading cause of death in the United States, and mortality due to injury has risen over the past decade. The social determinants behind these rising trends have not been well documented. This study examines the relationship between county-level poverty and unintentional injury mortality in the United States from 1999–2012. Complete annual compressed mortality and population data for 1999–2012 were obtained from the National Center for Health Statistics and linked with census yearly county poverty measures. The outcomes examined were unintentional injury fatalities, overall and by six specific mechanisms: motor vehicle collisions, falls, accidental discharge of firearms, drowning, exposure to smoke or fire, and unintentional poisoning. Age-adjusted mortality rates and time trends for county poverty categories were calculated, and multivariate negative binomial regression was used to determine changes over time in both the relative risk of living in high poverty concentration areas and the population attributable fraction. Age-adjusted mortality rates for counties with > 20% poverty were 66% higher mortality in 1999 compared with counties with < 5% poverty (45.25 vs. 27.24 per 100,000; 95% CI for rate difference 15.57,20.46), and that gap widened in 2012 to 79% (44.54 vs. 24.93; 95% CI for rate difference 17.13,22.09). The relative risk of living in the highest poverty counties has increased for all injury mechanisms with the exception of accidental discharge of firearms. The population attributable fraction for all unintentional injuries rose from 0.22 (95% CI 0.13,0.30) in 1999 to 0.35 (95% CI 0.22,0.45) in 2012. This is the first study that uses comprehensive mortality data to document the associations between county poverty and injury mortality rates for the entire US population over a 14 year period. This study suggests that injury reduction interventions should focus on areas of high or increasing poverty. PMID:27144919

Controls on the Environmental Fate of Compounds Controlled by Coupled Hydrologic and Reactive Processes

Current understanding of how compounds interact with hydrologic processes or reactive processes have been well established. However, the environmental fate for compounds that interact with hydrologic AND reactive processes is not well known, yet critical in evaluating environmental risk. Evaluations of risk are often simplified to homogenize processes in space and time and to assess processes independently of one another. However, we know spatial heterogeneity and time-variable reactivities complicate predictions of environmental transport and fate, and is further complicated by the interaction of these processes, limiting our ability to accurately predict risk. Compounds that interact with both systems, such as photolytic compounds, require that both components are fully understood in order to predict transport and fate. Release of photolytic compounds occurs through both unintentional releases and intentional loadings. Evaluating risks associated with unintentional releases and implementing best management practices for intentional releases requires an in-depth understanding of the sensitivity of photolytic compounds to external controls. Lampricides, such as 3-trifluoromethyl-4-nitrophenol (TFM), are broadly applied in the Great Lakes system to control the population of invasive sea lamprey. Over-dosing can yield fish kills and other detrimental impacts. Still, planning accounts for time of passage and dilution, but not the interaction of the physical and chemical systems (i.e., storage in the hyporheic zone and time-variable decay rates). In this study, we model a series of TFM applications to test the efficacy of dosing as a function of system characteristics. Overall, our results demonstrate the complexity associated with photo-sensitive compounds through stream-hyporheic systems, and highlight the need to better understand how physical and chemical systems interact to control transport and fate in the environment.

Mind-Wandering With and Without Intention

Seli, Paul; Risko, Evan F.; Smilek, Daniel; Schacter, Daniel L.

2016-01-01

The past decade has seen a surge of research examining mind-wandering, but most of this research has not considered the potential importance of distinguishing between intentional and unintentional mind-wandering. However, a recent series of papers has demonstrated that mind-wandering reported in empirical investigations frequently occurs with and without intention, and more critically, that intentional and unintentional mind-wandering are dissociable. This emerging literature suggests that to increase clarity in the literature, there is a need to reconsider the bulk of the mind-wandering literature with an eye toward deconvolving these two different cognitive experiences. In this review, we highlight recent trends in investigations of the intentionality of mind-wandering and outline a novel theoretical framework regarding the mechanisms underlying intentional and unintentional mind-wandering.

The objective of this study was to examine risk assessment practices for suicide and unintentional overdose to inform ongoing care in substance use disorder clinics. Focus groups were conducted via telephone among a random sample of treatment providers (N = 19) from Veterans Health Administration substance use disorder clinics across the nation. Themes were coded by research staff. Treatment providers reported consistent and clear guidelines for risk assessment of suicide among patients. Unintentional overdose questions elicited dissimilar responses which indicated a lack of cohesion and uniformity in risk assessment practices across clinics. Suicide risk assessment protocols are cohesively implemented by treatment providers. Unintentional overdose risk, however, may be less consistently assessed in clinics.

Intention Modulates the Effect of Punishment Threat in Norm Enforcement via the Lateral Orbitofrontal Cortex.

Zhang, Yuan; Yu, Hongbo; Yin, Yunlu; Zhou, Xiaolin

2016-08-31

Although economic theories suggest that punishment threat is crucial for maintaining social norms, counterexamples are noted in which punishment threat hinders norm compliance. Such discrepancy may arise from the intention behind the threat: unintentionally introduced punishment threat facilitates, whereas intentionally introduced punishment threat hinders, norm compliance. Here, we combined a dictator game and fMRI to investigate how intention modulates the effect of punishment threat on norm compliance and the neural substrates of this modulation. We also investigated whether this modulation can be influenced by brain stimulation. Human participants divided an amount of money between themselves and a partner. The partner (intentionally) or a computer program (unintentionally) decided to retain or waive the right to punish the participant upon selfish distribution. Compared with the unintentional condition, participants allocated more when the partner intentionally waived the power of punishment, but less when the partner retained such power. The right lateral orbitofrontal cortex (rLOFC) showed higher activation when the partner waived compared with when the computer waived or when the partner retained the power. The functional connectivity between the rLOFC and the brain network associated with intention/mentalizing processing was predictive of the allocation difference induced by intention. Moreover, inhibition or activation of the rLOFC by brain stimulation decreased or increased, respectively, the participants' reliance on the partner's intention during monetary allocation. These findings demonstrate that the perceived intention of punishment threat plays a crucial role in norm compliance and that the LOFC is casually involved in the implementation of intention-based cooperative decisions. Does punishment threat facilitate or hinder norm enforcement? So far, cognitive neuroscience research offers equivocal evidence. By directly manipulating the intention behind punishment threat, we demonstrate that intention modulates the effectiveness of punishment threat. Moreover, we show that inhibition or activation of the right lateral orbitofrontal cortex (rLOFC) decreased or increased the effect of punishment threat in the intentional context, but not in the unintentional context, suggesting the casual involvement of the rLOFC in intention-based cooperative decisions.

PURPOSE This study describes key elements of the transition to a patient-centered medical home (PCMH) model at Southcentral Foundation (SCF), a tribally owned and managed primary care system, and evaluates changes in emergency care use for any reason, for asthma, and for unintentional injuries, during and after the transition. METHODS We conducted a time series analyses of emergency care use from medical record data. We also conducted 45 individual, in-depth interviews with PCMH patients (customer-owners), primary care clinicians, health system employees, and tribal leaders. RESULTS Emergency care use for all causes was increasing before the PCMH implementation, dropped during and immediately after the implementation, and subsequently leveled off. Emergency care use for adult asthma dropped before, during, and immediately after implementation, subsequently leveling off approximately 5 years after implementation. Emergency care use for unintentional injuries, a comparison variable, showed an increasing trend before and during implementation and decreasing trends after implementation. Interview participants observed improved access to primary care services after the transition to the PCMH tempered by increased staff fatigue. Additional themes of PCMH transformation included the building of relationships for coordinated, team-based care, and the important role of leadership in PCMH implementation. CONCLUSIONS All reported measures of emergency care use show a decreasing trend after the PCMH implementation. Before the implementation, overall use and use for unintentional injuries had been increasing. The combined quantitative and qualitative results are consistent with decreased emergency care use resulting from a decreased need for emergency care services due to increased availability of primary care services and same-day appointments.

A Food Imitating Product (FIP) is a household cleaner or a personal care product that exhibits food attributes in order to enrich consumption experience. As revealed by many cases worldwide, such a marketing strategy led to unintentional self-poisonings and deaths. FIPs therefore constitute a very serious health and public policy issue. To understand why FIPs are a threat, we first conducted a qualitative analysis on real-life cases of household cleaners and personal care products-related phone calls at a poison control center followed by a behavioral experiment. Unintentional self-poisoning in the home following the accidental ingestion of a hygiene product by a healthy adult is very likely to result from these products being packaged like foodstuffs. Our hypothesis is that FIPs are non-verbal food metaphors that could fool the brain of consumers. We therefore conducted a subsequent functional neuroimaging (fMRI) experiment that revealed how visual processing of FIPs leads to cortical taste inferences. Considered in the grounded cognition perspective, the results of our studies reveal that healthy adults can unintentionally categorize a personal care product as something edible when a food-like package is employed to market nonedible and/or dangerous products. Our methodology combining field (qualitative) and laboratory (behavioral and functional neuroimaging) findings could be of particular relevance for policy makers, as it can help screening products prior to their market release--e.g. the way they are packaged and how they can potentially confuse the mind of consumers--and therefore save lives.

To describe a feasible quality improvement system to manage feeding assistance care processes in an assisted living facility (ALF) that provides dementia care and the use of these data to maintain the quality of daily care provision and prevent unintentional weight loss. Supervisory ALF staff used a standardized observational protocol to assess feeding assistance care quality during and between meals for 12 consecutive months for 53 residents receiving dementia care. Direct care staff received feedback about the quality of assistance and consistency of between-meal snack delivery for residents with low meal intake and/or weight loss. On average, 78.4% of the ALF residents consumed more than one-half of each served meal and/or received staff assistance during meals to promote consumption over the 12 months. An average of 79.7% of the residents were offered snacks between meals twice per day. The prevalence of unintentional weight loss averaged 1.3% across 12 months. A quality improvement system resulted in sustained levels of mealtime feeding assistance and between-meal snack delivery and a low prevalence of weight loss among ALF residents receiving dementia care. Given that many ALF residents receiving dementia care are likely to be at risk for low oral intake and unintentional weight loss, ALFs should implement a quality improvement system similar to that described in this project, despite the absence of regulations to do so.

Contrary to the reported clinical, anatomic, and histologic evidence of communication between the 2 pleural cavities through the mediastinum in the dog, it was found that acute or chronic pathologic processes in one pleural cavity remained confined to that cavity unless the mediastinum was mechanically injured. These results were obtained in a series of experiments involving 39 dogs in which hemothorax or pyothorax or pneumothorax was unintentionally induced.

To characterize the rates, root causes, and clinical effects of unintentional exposures to buprenorphine sublingual formulations among young children and to determine whether exposure characteristics differ between formulations. Unintentional exposures to buprenorphine-containing products among children 28 days to less than 6 years old were collected from the Researched Abuse, Diversion, and Addiction-Related Surveillance System Poison Center Program and Reckitt Benckiser Pharmaceuticals' pharmacovigilance system from October 2009-March 2012. After adjustment for drug availability, negative binomial regression was used to estimate average exposure rates. Root cause assessment was conducted, and an expert clinician panel adjudicated causality and severity of moderate to severe adverse events (AEs). A total of 2380 cases were reviewed, including 4 deaths. Exposures to buprenorphine-naloxone combination film were significantly less frequent than exposures to buprenorphine tablets (rate ratio 3.5 [95% CI, 2.7-4.5]) and buprenorphine-naloxone combination tablets (rate ratio 8.8 [7.2-10.6]). The most commonly identified root causes were medication stored in sight, accessed from a bag or purse, and not stored in the original packaging. Among 536 panel review cases, the most common AEs reported for all formulations were lethargy, respiratory depression, miosis, and vomiting. The highest level AE severity did not differ significantly by formulation. Unintentional exposure to buprenorphine can cause central nervous system depression, respiratory depression, and death in young children. Exposure rates to film formulations are significantly less than to tablet formulations. Package and storage deficiencies contribute to unintentional exposures in young children.

Schizophrenia is a severe mental disorder that is highly characterized by social cognitive impairments. Most studies investigating these impairments focus on one specific social domain such as emotion recognition. However, in daily life, processing complex social situations relies on the combination of several social cognitive and affective processes simultaneously rather than one process alone. A modified version of the economically based Ultimatum Game was used to measure the interplay between fairness, intentionality, and emotion considerations during social decision-making. In this task, participants accept or reject fair and unfair monetary offers proposed intentionally or unintentionally by either angry, happy, neutral, or sad proposers. Behavioral data was collected from a group of schizophrenia patients (N = 35) and a group of healthy individuals (N = 30). Like healthy participants, schizophrenia patients differentiated between fair and unfair offers by rejecting unfair offers more compared to fair offers. However, overall patients did reject more fair offers, indicating that their construct of fairness operates within different margins. In both groups, intentional unfair offers were rejected more compared to unintentional ones, indicating a normal integration of intentionality considerations in schizophrenia. Importantly, healthy subjects also differentiated between proposers’ emotion when rejecting unfair offers (more rejections from proposers depicting angry faces compared to proposers depicting, happy, neutral, or sad faces). Schizophrenia patients’ decision behavior on the other hand, was not affected by the proposers’ emotions. The current study thus shows that schizophrenia patients have specific problems with processing and integrating emotional information. Importantly, the finding that patients display normal fairness and intentionality considerations emphasizes preservation of central social cognitive processes in schizophrenia. PMID:26257699

To study the epidemiology and risk factors for unintentional exposure to poisoning among the Jewish and the Arab population in the Sharon area in Israel. We prospectively evaluated visits to the pediatric emergency department because of unintentional poisoning exposure, at the Meir General Hospital. We collected demographic data, substance exposure data, and the clinical outcome of the poisoning. During the 5 years of the study, 502 children were evaluated for unintentional poisoning, 84% Jewish and 16% Arabs; 88.5% occurred in children younger than 5 years, with a peak incidence at the age of 2 years (39.5%). Medications including hormones, vitamins, and antibiotics were the most common cause of exposure. Most children (95%) had no symptoms or abnormal findings on physical examination (84%), and most (85%) were discharged after several hours of observation. However, children of Arab origin presented with severe clinical manifestations because of a high rate of pesticide poisoning. There was 1 death from organic phosphate poisoning. Exposure to poisoning is commonly encountered in children. Pesticides exposure is more common in the Arab community and is usually associated with more severe clinical manifestations. Educational preventive programs are mandatory.

Project NOAH: Regulating modern sea-level rise. Phase II: Jerusalem Underground

NASA Astrophysics Data System (ADS)

Newman, Walter S.; Fairbridge, Rhodes W.

This proposal builds a high-speed inter-urban express between Jerusalem and Tel Aviv, generates 1500 megawatts of hydroelectric energy, curtails littoral erosion, builds a port along the Israeli Mediterranean coast and demands peaceful cooperation on both sides of the Jordan River. Phase II represents a pilot project demonstrating the feasibility of continuing to regulate world sea-level by a new series of water regulation schemes. Phase I previously described all those projects already completed or underway which have inadvertently and/or unintentionally served the purpose of sea-level regulation. These forms of Phase I sea-level regulation include large and small reservoirs, irrigation projects, water infiltration schemes, farm ponds, and swimming and reflecting pools. All these water storage projects have already exercised a very appreciable brake on 20th century sea-level rise. Phase II outlines a high-visibility proposal which will serve to illustrate the viability of “Project NOAH”.

A redundant three axis analog control system was designed and developed to back up a digital fly by wire control system for an F-8C airplane. The mechanization and operational experience with the backup control system, the problems involved in synchronizing it with the primary system, and the reliability of the system are discussed. The backup control system was dissimilar to the primary system, and it provided satisfactory handling through the flight envelope evaluated. Limited flight tests of a variety of control tasks showed that control was also satisfactory when the backup control system was controlled by a minimum displacement (force) side stick. The operational reliability of the F-8 digital fly by wire control system was satisfactory, with no unintentional downmodes to the backup control system in flight. The ground and flight reliability of the system's components is discussed.

2016-12-01

Siderastrea glynni Budd & Guzmán, 1994 was erroneously erected from live colonies of S. siderea (Ellis & Solander, 1768) unintentionally transferred from the Caribbean to the Pacific side of the Isthmus of Panamá. These corals had been used in experiments conducted in the early 1980s by KH Kleemann at Urabá Island, Taboga Islands, Gulf of Panamá, at the same site of the subsequent S. glynni discovery. Here, we offer evidence that live fragments deposited at Urabá Island in 1982 are the same found by Guzmán in 1992, and were inadvertently introduced from colonies of Caribbean S. siderea that were presumed to be dead. This morphological study builds on and supports recent genetic analyses of the S. glynni holobiont. In light of these findings, S. glynni should be regarded as a subjective junior synonym of S. siderea.

Tilmicosin phosphate is a macrolide antibiotic that is used to treat cattle for pathogens that cause Bovine Respiratory Disease. A 28-year-old man with no prior history of heart disease developed severe chest pain, inverted T waves, and intraventricular conduction delay on EKG and mild elevation of cardiac enzymes 5 hours after unintentional injection of less than half of a 12cc syringe filled with Micotil 300 (tilmicosin phosphate 300 mg/mL, propylene glycol 25%, phosphoric acid, water for injection). The patient made an uneventful recovery after hospitalization. This case provides evidence that unintentional injection of tilmicosin can cause cardiac symptoms and laboratory evidence of myocardial injury. Tilmicosin should always be administered by properly trained personnel who are using techniques designed to reduce the risk of accidental self-injection.

Mind-Wandering With and Without Intention.

2016-08-01

The past decade has seen a surge of research examining mind-wandering, but most of this research has not considered the potential importance of distinguishing between intentional and unintentional mind-wandering. However, a recent series of papers have demonstrated that mind-wandering reported in empirical investigations frequently occurs with and without intention, and, more crucially, that intentional and unintentional mind-wandering are dissociable. This emerging literature suggests that, to increase clarity in the literature, there is a need to reconsider the bulk of the mind-wandering literature with an eye toward deconvolving these two different cognitive experiences. In this review we highlight recent trends in investigations of the intentionality of mind-wandering, and we outline a novel theoretical framework regarding the mechanisms underlying intentional and unintentional mind-wandering.

National level estimates of injuries are not readily available for developing countries. This study estimated the annual incidence, patterns and severity of unintentional injuries among persons over five years of age in Pakistan. National Health Survey of Pakistan (NHSP 1990-94) is a nationally representative survey of the household. Through a two-stage stratified design, 18, 315 persons over 5 years of age were interviewed to estimate the overall annual incidence, patterns and severity of unintentional injuries for males and females in urban and rural areas over the preceding one year. Weighted estimates were computed adjusting for complex survey design using surveyfreq and surveylogistic option of SAS 9.1 software. The overall annual incidence of all unintentional injuries was 45.9 (CI: 39.3-52.5) per 1000 per year; 59.2 (CI: 49.2-69.2) and 33.2 (CI: 27.0-39.4) per 1000 per year among males and females over five years of age, respectively. An estimated 6.16 million unintentional injuries occur in Pakistan annually among persons over five years of age. Urban and rural injuries were 55.9 (95% CI: 48.1-63.7) and 41.2 (95% CI: 32.2-50.0) per 1000 per year, respectively. The annual incidence of injuries due to falls were 22.2 (95% CI: 18.0-26.4), poisoning 3.3 (95%CI: 0.5-6.1) and burn was 1.5 (95%CI: 0.9-2.1) per 1000 per year. The majority of injuries occurred at home 19.2 (95%CI: 16.0-22.4) or on the roads 17.0 (95%CI: 13.8-20.2). Road traffic/street, school and urban injuries were more likely to result in handicap. There is high burden of unintentional injuries among persons over five years of age in Pakistan. These results are useful to plan further studies and prioritizing prevention programs on injuries nationally and other developing countries with similar situation.

Source, Managemnt and Quantification of Unintentional POPs (PCDDD/Fs) in Nepal

2010-05-01

The aim to prepare and present this paper is to highlight the source, management and quantification of the unintentional POPs in an unindustrialized least developing landlocked small country Nepal. The methodology adopted for this is the review of the relevant research documents and national initiative towards addressing this issues complemented with sharing of the first hand experience from the implementation of the POPs management activities undertaken by our organization. Nepal is a small country of size 147181 sq.km but having large sources of POPs including unintentional POPs (PCDD/Fs) mainly because of weak enforcement of the existing environment related laws, standards and international commitment including POPs Convention. Country became homes to about 75 tons of Obsolete Pesticide since last 30 years including about 44 percent (33 tons out of 75) are of known POPs. These obsolete pesticides including identified POPs have been poorly stored in some about 25 locations throughout the country. The major warehouse accommodating about 50 tons at Amlekhgunj has been located just in front of a high school where about 1000 children are being studying and found to have some health related problem due to the gasses emission from the warehouse as well as school playground field contaminated with these POPs pesticides. The playground soil contamination has been found from routine examination of the soil samples. In addition to pesticides including POPs were used in the agriculture and public health field in the past, there are several other practices as well as anthropogenic activities producing PCDD/Fs. The annual inventory of countrywide emission of unintentional POPs was estimated to be 312.55 g TEQ for Nepal (MOE 2004). This is very high for a country like Nepal least developing in terms of industrial and economy. This estimation was based on the UNEP Toolkit which has included the broad categories of waste such as waste incineration, ferrous and non ferrous metal production, power generation and cooking using biomass, production of mineral products, transportation, uncontrolled combustion processes production of chemicals and consumer goods, disposal and land filling and miscellaneous. However, it does not account all the sources of the unintentional POPs emission. There are increasing amount of PCDD/Fs emission from other unidentified and/or under estimate sources. An another estimates just for medical waste incineration amount to be 57.37 g TEQ / year based on the current rate of medical waste generation, incineration proportion and considering small box-type batch incinerator with no afterburner as it is mostly adopted in all individual health care institutions. Toward management of POPs, earlier government is not found to be serious as there is still provision of waste incineration in its waste management guidelines including medical waste and has also given Environment Impact Assessment (EIA) clearance to some of the project with waste incineration components. It is important to make the highlight here that the waste incinerator no matter of its art of standards is the indentified major source of unintentional POPs such as PCDD/Fs the known human carcinogen. However, in the recent years, there was increasing concerned of the government as it has come up with the National Implementation Plan (NIP) for Stockholm Convention on Persistent Organic Pollutants with clear identification, prioritization as well as developed program of action linked with monitoring and reporting mechanism. Some of the recent development projects with FAO and GTZ towards realization of the few prioritized plan of action about the sound management of obsolete pesticides including POPs can be considered as remarkable positive progress towards overall development in this field which upon successful implementation will help to improve the country situation.

Keeping pain in mind: a motivational account of attention to pain.

PubMed

Van Damme, Stefaan; Legrain, Valéry; Vogt, Julia; Crombez, Geert

2010-02-01

Attention is a key concept in many theories of pain perception. A clinically popular idea is that pain is more intense in persons who are hypervigilant for or bias their attention to pain information. So far, evidence for such bias in pain patients as compared to healthy persons is inconclusive. Furthermore, studies investigating the effects of distracting attention away from pain have shown contradictory results. In this review, we present a motivational perspective on attentional processing of pain that accounts for these inconclusive research findings. We argue that pain always has to be considered within a context of goal pursuit. From this perspective, two largely unexplored theoretical assumptions are introduced. First, when pain occurs during the pursuit of a certain goal, it may unintentionally capture attention although it is not relevant for the goal. Whether such unintentional attentional capture happens is not only dependent upon the characteristics of the pain but also on the characteristics of the focal goal. Second, attention to pain and pain-related information might be driven by a focal goal related to pain. Attentional processing of pain information will be particularly enhanced when the focal goal is related to pain management (e.g., attempting to gain control). Future research should systematically investigate the role of motivation and goal pursuit in the attentional processing of pain-related information. This motivational perspective offers a powerful framework to explain inter- and intra-individual differences in the deployment of attention to pain-related information.

Objectives Given the likelihood of increased hot weather due to climate change, it is crucial to have prevention measures in place to reduce the health burden of high temperatures and heat waves. The aim of this review is to summarise and evaluate the evidence on the effects of summertime weather on unintentional injuries in high-income countries. Design 3 databases (Global Public Health, EMBASE and MEDLINE) were searched by using related keywords and their truncations in the title and abstract, and reference lists of key studies were scanned. Studies reporting heatstroke and intentional injuries were excluded. Results 13 studies met our inclusion criteria. 11 out of 13 studies showed that the risk of unintentional injuries increases with increasing ambient temperatures. On days with moderate temperatures, the increased risk varied between 0.4% and 5.3% for each 1°C increase in ambient temperature. On extreme temperature days, the risk of injuries decreased. 2 out of 3 studies on occupational accidents found an increase in work-related accidents during high temperatures. For trauma hospital admissions, 6 studies reported an increase during hot weather, whereas 1 study found no association. The evidence for impacts on injuries by subgroups such as children, the elderly and drug users was limited and inconsistent. Conclusions The present review describes a broader range of types of unintentional fatal and non-fatal injuries (occupational, trauma hospital admissions, traffic, fire entrapments, poisoning and drug overdose) than has previously been reported. Our review confirms that hot weather can increase the risk of unintentional injuries and accidents in high-income countries. The results are useful for injury prevention strategies. PMID:26868947

Napping is associated with both positive and negative health outcomes among older adults. However, the association between particular napping characteristics (eg, frequency, duration, and whether naps were intentional) and daytime function is unclear. Participants were 2,739 community-dwelling Medicare beneficiaries aged ≥65 years from the nationally representative National Health and Aging Trends Study. Participants reported napping frequency, duration, and whether naps were intentional versus unintentional. Restricted participation in valued activities was measured by self-report. After adjusting for potential confounders and nighttime sleep duration, those who took intentional and unintentional naps had a greater odds of any valued activity restriction (ie, ≥1 valued activity restriction), compared to those who rarely/never napped (unintentional odds ratio [OR] = 1.34, 95% confidence interval [CI] 1.01, 1.79, intentional OR = 1.49, 95% CI 1.09, 2.04). There was no difference between unintentional napping and intentional napping with respect to any valued activity restriction after adjustment for demographics. Compared to participants napping "some days," those napping most days/every day had a greater odds of any valued activity restriction (OR = 1.68, 95% CI 1.30, 2.16). Moreover, each 30-minute increase in average nap duration was associated with a 25% greater odds of any valued activity restriction (OR = 1.25, 95% CI 1.10, 1.43). Older adults who took more frequent or longer naps were more likely to report activity restrictions, as were those who took intentional or unintentional naps. Additional longitudinal studies with objective measures of sleep are needed to further our understanding of associations between napping characteristics and daytime dysfunction. © The Author 2017.

McAninch, Jana; Greene, Christina; Sorkin, John D.; Lavoie, Marie-Claude; Smith, Gordon S.

2014-01-01

Background Links between mental illness, self-inflicted injury, and interpersonal violence are well recognized, but the association between poor mental health and unintentional injuries is not well understood. Methods We used the 2010 National Health Interview Survey to assess the association between psychological distress and unintentional non-occupational injuries among U.S. adults. Psychological distress was measured by the Kessler Psychological Distress Scale, a symptom scale shown to identify community-dwelling persons with mental illness. Multivariable logistic regression was used to estimate adjusted odds ratios (AOR) and 95% confidence intervals. Results Of the 26,776 individuals analyzed, 2.5% reported a medically-attended unintentional injury in the past three months. Those with moderate and severe psychological distress had 1.5 [1.2-1.8] and 2.0 [1.4 -2.8] times higher odds of injury, respectively, as compared to those with low distress levels, after adjusting for age, sex, race, marital status, education level, alcohol use, physical functional limitation, medical comorbidity, employment status, and health insurance status. Psychological distress was significantly associated with falls [AOR 1.4 (1.1-1.9)] and sprain/strain injuries [AOR 2.0 (1.5-2.8)], but not transportation-related injuries [AOR 1.2 (0.7-1.9)] or fractures [AOR 1.1 (0.8-1.6)]. Conclusion Among community-dwelling U.S. adults, psychological distress is significantly associated with unintentional non-occupational injury, and the magnitude of association increases with severity of distress. The association between psychological distress and injury may be particularly strong for falls and sprain/strain injuries. These findings draw attention to a large group of at-risk individuals that may merit further targeted research, including longitudinal studies. PMID:24174466

Routine vaccination against smallpox (variola) ceased in the US in 1976. However, in 2002 limited coverage for military personnel and some healthcare workers was reinstituted. In March 2008, ACAM2000® replaced Dryvax® as the vaccine used in the United States against smallpox. Unintentional transfer of vaccinia virus from a vaccination site by autoinoculation or contact transmission, can have significant public health implications. We summarize unintentional virus transfer AEs associated with ACAM2000® since March 2008 and compare with Dryvax®. We identified 309 reports for ACAM2000® with skin or ocular involvement, of which 93 were autoinoculation cases and 20 were contact transmission cases. The rate for reported cases of autoinoculation was 20.6 per 100,000 vaccinations and for contact transmission was 4.4 per 100,000 vaccinations. Eighteen contact transmission cases could be attributed to contact during a sporting activity (45%) or intimate contact (45%). Of the 113 unintentional transfer cases, 6 met the case definition for ocular vaccinia. The most common locations for all autoinoculation and contact cases were arm/elbow/shoulder (35/113; 31%) and face (24/113; 21%). Methods We reviewed 753 reports associated with smallpox in the Vaccine Adverse Event Reporting System and CDC Poxvirus consultation log, reported from March 2008 to August 2010. Reports were classified into categories based upon standard case definitions. Overall, unintentional transfer events for ACAM2000® and Dryvax® are similar. We recommend continued efforts to prevent transfer events and continuing education for healthcare providers focused on recognition of vaccinia lesions, proper sample collection, and laboratory testing to confirm diagnosis.

Discriminating between intentional and unintentional gaze fixation using multimodal-based fuzzy logic algorithm for gaze tracking system with NIR camera sensor

NASA Astrophysics Data System (ADS)

Naqvi, Rizwan Ali; Park, Kang Ryoung

2016-06-01

Gaze tracking systems are widely used in human-computer interfaces, interfaces for the disabled, game interfaces, and for controlling home appliances. Most studies on gaze detection have focused on enhancing its accuracy, whereas few have considered the discrimination of intentional gaze fixation (looking at a target to activate or select it) from unintentional fixation while using gaze detection systems. Previous research methods based on the use of a keyboard or mouse button, eye blinking, and the dwell time of gaze position have various limitations. Therefore, we propose a method for discriminating between intentional and unintentional gaze fixation using a multimodal fuzzy logic algorithm applied to a gaze tracking system with a near-infrared camera sensor. Experimental results show that the proposed method outperforms the conventional method for determining gaze fixation.

Benzodiazepines: a major component in unintentional prescription drug overdoses with opioid analgesics.

PubMed

Jann, Michael; Kennedy, William Klugh; Lopez, Gaylord

2014-02-01

The misuse and abuse of prescription medications in the United States continues to increase despite interventions by health care professionals, regulatory, and law enforcement agencies. Opioid analgesics are the leading class of prescription drugs that have caused unintentional overdose deaths. Benzodiazepines when taken alone are relatively safe agents in overdose. However, a 5-fold increase in deaths attributed to benzodiazepines occurred from 1999 to 2009. Emergency department visits related to opioid analgesics increased by 111% followed by benzodiazepines 89%. During 2003 to 2009, the 2 prescriptions drugs with the highest increase in death rates were oxycodone 264.6% and alprazolam 233.8%. Therefore, benzodiazepines have a significant impact on prescription drug unintentional overdoses second only to the opioid analgesics. The combination prescribing of benzodiazepines and opioid analgesics commonly takes place. The pharmacokinetic drug interactions between benzodiazepines and opioid analgesics are complex. The pharmacodynamic actions of these agents differ as their combined effects produce significant respiratory depression. Physician and pharmacy shopping by patients occurs, and prescription drug-monitoring programs can provide important information on benzodiazepine and opioid analgesic prescribing patterns and patient usage. Health care professionals need to inform patients and work closely with regulatory agencies and legislatures to stem the increasing fatalities from prescription drug unintentional overdoses.

State gun safe storage laws and child mortality due to firearms.

Cummings, P; Grossman, D C; Rivara, F P; Koepsell, T D

1997-10-01

Since 1989, several states have passed laws that make gun owners criminally liable if someone is injured because a child gains unsupervised access to a gun. These laws are controversial, and their effect on firearm-related injuries is unknown. To determine if state laws that require safe storage of firearms are associated with a reduction in child mortality due to firearms. An ecological study of firearm mortality from 1979 through 1994. All 50 states and the District of Columbia. All children younger than 15 years. Unintentional deaths, suicides, and homicides due to firearms. Laws that make gun owners responsible for storing firearms in a manner that makes them inaccessible to children were in effect for at least 1 year in 12 states from 1990 through 1994. Among children younger than 15 years, unintentional shooting deaths were reduced by 23% (95% confidence interval, 6%-37%) during the years covered by these laws. This estimate was based on within-state comparisons adjusted for national trends in unintentional firearm-related mortality. Gun-related homicide and suicide showed modest declines, but these were not statistically significant. State safe storage laws intended to make firearms less accessible to children appear to prevent unintentional shooting deaths among children younger than 15 years.

Underestimates of unintentional firearm fatalities: comparing Supplementary Homicide Report data with the National Vital Statistics System

Objective: A growing body of evidence suggests that the nation's vital statistics system undercounts unintentional firearm deaths that are not self inflicted. This issue was examined by comparing how unintentional firearm injuries identified in police Supplementary Homicide Report (SHR) data were coded in the National Vital Statistics System. Methods: National Vital Statistics System data are based on death certificates and divide firearm fatalities into six subcategories: homicide, suicide, accident, legal intervention, war operations, and undetermined. SHRs are completed by local police departments as part of the FBI's Uniform Crime Reports program. The SHR divides homicides into two categories: "murder and non-negligent manslaughter" (type A) and "negligent manslaughter" (type B). Type B shooting deaths are those that are inflicted by another person and that a police investigation determined were inflicted unintentionally, as in a child killing a playmate after mistaking a gun for a toy. In 1997, the SHR classified 168 shooting victims this way. Using probabilistic matching, 140 of these victims were linked to their death certificate records. Results: Among the 140 linked cases, 75% were recorded on the death certificate as homicides and only 23% as accidents. Conclusion: Official data from the National Vital Statistics System almost certainly undercount firearm accidents when the victim is shot by another person. PMID:12226128

Objectives. We examined whether neighborhood social characteristics (income distribution and family fragmentation) and physical characteristics (clean sidewalks and dilapidated housing) were associated with the risk of fatalities caused by analgesic overdose. Methods. In a case-control study, we compared 447 unintentional analgesic opioid overdose fatalities (cases) with 3436 unintentional nonoverdose fatalities and 2530 heroin overdose fatalities (controls) occurring in 59 New York City neighborhoods between 2000 and 2006. Results. Analgesic overdose fatalities were less likely than nonoverdose unintentional fatalities to have occurred in higher-income neighborhoods (odds ratio [OR] = 0.82; 95% confidence interval [CI] = 0.70, 0.96) and more likely to have occurred in fragmented neighborhoods (OR = 1.35; 95% CI = 1.05, 1.72). They were more likely than heroin overdose fatalities to have occurred in higher-income (OR = 1.31; 95% CI = 1.12, 1.54) and less fragmented (OR = 0.71; 95% CI = 0.55, 0.92) neighborhoods. Conclusions. Analgesic overdose fatalities exhibit spatial patterns that are distinct from those of heroin and nonoverdose unintentional fatalities. Whereas analgesic fatalities typically occur in lower-income, more fragmented neighborhoods than nonoverdose fatalities, they tend to occur in higher-income, less unequal, and less fragmented neighborhoods than heroin fatalities.

We applied the theory of synergies to analyze the processes that lead to unintentional decline in isometric fingertip force when visual feedback of the produced force is removed. We tracked the changes in hypothetical control variables involved in single fingertip force production based on the equilibrium-point hypothesis, namely, the fingertip referent coordinate (RFT) and its apparent stiffness (CFT). The system's state is defined by a point in the {RFT; CFT} space. We tested the hypothesis that, after visual feedback removal, this point (1) moves along directions leading to drop in the output fingertip force, and (2) has even greater motion along directions that leaves the force unchanged. Subjects produced a prescribed fingertip force using visual feedback, and attempted to maintain this force for 15 s after the feedback was removed. We used the “inverse piano” apparatus to apply small and smooth positional perturbations to fingers at various times after visual feedback removal. The time courses of RFT and CFT showed that force drop was mostly due to a drift in RFT towards the actual fingertip position. Three analysis techniques, namely, hyperbolic regression, surrogate data analysis, and computation of motor-equivalent and non-motor-equivalent motions, suggested strong co-variation in RFT and CFT stabilizing the force magnitude. Finally, the changes in the two hypothetical control variables {RFT; CFT} relative to their average trends also displayed covariation. On the whole the findings suggest that unintentional force drop is associated with (a) a slow drift of the referent coordinate that pulls the system towards a low-energy state, and (b) a faster synergic motion of RFT and CFT that tends to stabilize the output fingertip force about the slowly-drifting equilibrium point.

Childhood unintentional injury represents an important global health problem. Many unintentional injuries experienced by children aged under 5 years occur within the home and are preventable. The aim of this study was to explore the approaches used by parents of children under five in order to help prevent unintentional injuries in the home and the factors which influence their use. Understanding how parents approach risk-management in the home has important implications for injury practitioners. A multi-centre qualitative study using semi-structured interviews. A thematic approach was used to analyse the data. Sixty five parents of children aged under 5 years, from four study areas were interviewed: Bristol, Newcastle, Norwich and Nottingham. Three main injury prevention strategies used by parents were: a) Environmental such as removal of hazards, and use of safety equipment; b) parental supervision; and c) teaching, for example, teaching children about safety and use of rules and routine. Strategies were often used in combination due to their individual limitations. Parental assessment of injury risk, use of strategy and perceived effectiveness were fluid processes dependent on a child's character, developmental age and the prior experiences of both parent and child. Some parents were more proactive in their approach to home safety while others only reacted if their child demonstrated an interest in a particular object or activity perceived as being an injury risk. Parents' injury prevention practices encompass a range of strategies that are fluid in line with the child's age and stage of development; however, parents report that they still find it challenging to decide which strategy to use and when.

Injury, including unintentional injury and intentional injury, is the leading cause of death in people aged ⩽44 years. Doctors often treat acute injuries, assist in the rehabilitation process and provide injury prevention guidance to patients. Current undergraduate medical school curriculums lack content and consistency in providing training in this area. A matrix to show the integration of injury control and prevention principles into existing undergraduate medical school curriculums is proposed. PMID:17296681

In{sub x}Ga{sub 1–x}N/GaN single and multi quantum well (MQW) structures with x ≈ 0.13 were investigated optically by photoreflectance, photoluminescence excitation spectroscopy, and luminescence. Clear evidence of unintentional indium incorporation into the nominal GaN barrier layers is found. The unintentional In content is found to be around 3%. Inhomogeneous distribution of In atoms occurs within the distinct quantum well (QW) layers, which is commonly described as statistical alloy fluctuation and leads to the characteristic S-shape temperature shift of emission energy. Furthermore, differences in emission energy between the first and the other QWs of a MQW stack are found experimentally.

After GW passage into the pancreas, the most effective maneuver for CBD cannulation and pancreatitis prevention has not been determined. to study CBD cannulation and post-ERCP pancreatitis rates when a pancreatic stent is inserted after an unintentional GW cannulation of the pancreatic duct. a retrospective analysis of patients undergoing ERCP for biliary drainage that were included prospectively into a database. After unintentional GW cannulation of the pancreatic duct, a straight 5-Fr and 4-cm long plastic stent was inserted. The stents had no internal flaps to facilitate expulsion. CBD cannulation attempts were made above the stent. A pancreatic sphincterotomy was performed in patients older than 60 years before stent insertion. a total of 46 pancreatic stents were inserted during 154 ERCP (29.8%) procedures. In the stent group, CBD cannulation was accomplished in 44/46 (95.6%) subjects. A total of 21/46 (45.6%) pancreatic sphincterotomies were performed. Only 1/46 (2.17%) mild pancreatitis cases were observed and most stents were spontaneously expelled. in this study, the CBD was eventually reached with the insertion of a plastic pancreatic stent after an unintentional GW passage into the pancreatic duct while attempting a CBD cannulation. No adverse events were observed following pancreatic stent insertion.

The aim of this study was to explore the epidemiologic characteristics of unintentional poisoning cases and the factors associated with inpatient mortality. Data were retrieved from the National Health Insurance database from 2005 to 2007. Patients with diagnosis classifications of ICD-9-CM E850-E869 (unintentional poisoning) were selected. SPSS 18.0 software was used for the analysis. In Taiwan between 2005 and 2007, a total of 11,523 patients were hospitalised due to unintentional poisoning, with a hospitalisation rate of 16.83 per 100,000, of which 60.1% and 39.9% were attributable to drug poisoning and solid, liquid and gas substance poisoning, respectively. The hospitalisation rate in men was higher than that of women. The age group of 45-64 had the highest hospitalisation rate of 52.85 per 100,000. The inpatient mortality rate increased with the presence of the following factors: age of 65 or older, surgery or procedure, a higher Charlson Comorbidity Index (CCI), short length of hospital stays, acute respiratory failure, alcohol poisoning, pesticide poisoning and a higher-level hospital visited. Methanol, herbicides and organophosphorus pesticide intoxications are associated with higher mortality rates. Therefore, when caring for patients poisoned by the above agents, healthcare professionals should look out for their clinical development to ensure quality of care and to reduce mortality.

Human rights-based approach to unintentional injury prevention.

Unintentional injury remains an important global public health issue, and efforts to address it are often hampered by a lack of visibility, leadership, funding, infrastructure, capacity and evidence of effective solutions. The growing support for a socioecological model and a systems approach to prevention-along with the acknowledgement that injury prevention can be a byproduct of salutogenic design and activities-has increased opportunities to integrate unintentional injury prevention into other health promotion and disease prevention agendas. It has also helped to integrate it into the broader human development agenda through the Sustainable Development Goals. This growing support provides new opportunities to use a human rights-based approach to address the issue. The human rights-based approach is based on the idea that all members of society have social, economic and cultural rights and that governments are responsible and accountable for upholding those rights. It incorporates a systems approach, addresses inequity and places an emphasis on the most vulnerable corners of humanity. It also leverages legal statutes and provides organisations with the opportunity to build existing international goals and benchmarks into their monitoring efforts. This paper describes the approach and highlights how it can leverage attention and investment to address current challenges for unintentional injury. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Setting: Shelby County, Tennessee. Design: Retrospective observational analysis. Patients: County residents nine years of age or younger presenting to the children's medical center, its emergency department, or its outpatient clinics from 1990–97. Intervention: Implementation of a SAFE KIDS Coalition. Main outcome measures: Rates of unintentional injuries targeted by the SAFE KIDS Coalition that resulted in hospitalization or in death. Rates of motor vehicle occupant injuries that resulted in hospitalization or in death. Rates of non-targeted unintentional injuries, namely injuries secondary to animals and by exposure to toxic plants. Rates of severe injuries (defined as those targeted injuries that required hospitalization or resulted in death), and specifically, severe motor vehicle occupant injuries were compared before and after the inception of the coalition using Poisson regression analysis. Results: The relative risk of targeted severe injury rates decreased after implementation of the coalition even after controlling for changes in hospital admission rates. Specifically, severe motor vehicle occupant injury rates decreased 30% (relative risk 0.70; 95% confidence interval 0.54 to 0.89) after initiation of the coalition. Conclusions: The implementation of a SAFE KIDS Coalition was associated with a decrease in severe targeted injuries, most notably, severe motor vehicle occupant injuries. Although causality cannot be determined, these data suggest that the presence of a coalition may be associated with decreased severe unintentional injury rates. PMID:12226125

Limited longitudinal research has examined relationships between depression and injury, particularly in rural contexts. This paper reports cross-sectional and longitudinal analyses from the Australian Rural Mental Health Study (ARMHS) exploring relationships between “probable depression” episodes and unintentional injury. Participants completed four surveys over five years. Multivariate logistic regressions were employed to assess the causal effect of prior depression episodes on subsequent injury risk. Of 2621 baseline participants, 23.3% experienced a probable depression episode recently and 15.9% reported a serious injury during the previous 12 months. Factors associated with a 12-month injury at baseline included male gender, being unemployed or unable to work, being involved in a serious incident, hazardous alcohol use, and having experienced a recent depression episode. Longitudinal analyses revealed that probable depression was significantly associated with subsequent unintentional injury (OR 1.68, 99%CI 1.20–2.35), as was male gender (OR 1.39, 99%CI 1.06–1.82), while alcohol consumption did not mediate these relationships. Campaigns to reduce the impact of mental illness should consider unintentional injuries as a contributor, while injury prevention initiatives may benefit from addressing mental health issues. Such strategies are particularly important in rural and remote areas where injuries are more common and mental health services are less readily available. PMID:28926999

Security of practical private randomness generation

NASA Astrophysics Data System (ADS)

Pironio, Stefano; Massar, Serge

2013-01-01

Measurements on entangled quantum systems necessarily yield outcomes that are intrinsically unpredictable if they violate a Bell inequality. This property can be used to generate certified randomness in a device-independent way, i.e., without making detailed assumptions about the internal working of the quantum devices used to generate the random numbers. Furthermore these numbers are also private; i.e., they appear random not only to the user but also to any adversary that might possess a perfect description of the devices. Since this process requires a small initial random seed to sample the behavior of the quantum devices and to extract uniform randomness from the raw outputs of the devices, one usually speaks of device-independent randomness expansion. The purpose of this paper is twofold. First, we point out that in most real, practical situations, where the concept of device independence is used as a protection against unintentional flaws or failures of the quantum apparatuses, it is sufficient to show that the generated string is random with respect to an adversary that holds only classical side information; i.e., proving randomness against quantum side information is not necessary. Furthermore, the initial random seed does not need to be private with respect to the adversary, provided that it is generated in a way that is independent from the measured systems. The devices, however, will generate cryptographically secure randomness that cannot be predicted by the adversary, and thus one can, given access to free public randomness, talk about private randomness generation. The theoretical tools to quantify the generated randomness according to these criteria were already introduced in S. Pironio [Nature (London)NATUAS0028-083610.1038/nature09008 464, 1021 (2010)], but the final results were improperly formulated. The second aim of this paper is to correct this inaccurate formulation and therefore lay out a precise theoretical framework for practical device-independent randomness generation.

Perceiving pain in others: validation of a dual processing model.

Accurate perception of another person's painful distress would appear to be accomplished through sensitivity to both automatic (unintentional, reflexive) and controlled (intentional, purposive) behavioural expression. We examined whether observers would construe diverse behavioural cues as falling within these domains, consistent with cognitive neuroscience findings describing activation of both automatic and controlled neuroregulatory processes. Using online survey methodology, 308 research participants rated behavioural cues as "goal directed vs. non-goal directed," "conscious vs. unconscious," "uncontrolled vs. controlled," "fast vs. slow," "intentional (deliberate) vs. unintentional," "stimulus driven (obligatory) vs. self driven," and "requiring contemplation vs. not requiring contemplation." The behavioural cues were the 39 items provided by the PROMIS pain behaviour bank, constructed to be representative of the diverse possibilities for pain expression. Inter-item correlations among rating scales provided evidence of sufficient internal consistency justifying a single score on an automatic/controlled dimension (excluding the inconsistent fast vs. slow scale). An initial exploratory factor analysis on 151 participant data sets yielded factors consistent with "controlled" and "automatic" actions, as well as behaviours characterized as "ambiguous." A confirmatory factor analysis using the remaining 151 data sets replicated EFA findings, supporting theoretical predictions that observers would distinguish immediate, reflexive, and spontaneous reactions (primarily facial expression and paralinguistic features of speech) from purposeful and controlled expression (verbal behaviour, instrumental behaviour requiring ongoing, integrated responses). There are implicit dispositions to organize cues signaling pain in others into the well-defined categories predicted by dual process theory.

Aboriginal people in British Columbia (BC) have higher injury incidence than the general population. Our project describes variability among injury categories, time periods, and geographic, demographic and socio-economic groups. This report focuses on unintentional falls. We used BC's universal health care insurance plan as a population registry, linked to hospital separation and vital statistics databases. We identified Aboriginal people by insurance premium group and birth and death record notations. We identified residents of specific Aboriginal communities by postal code. We calculated crude incidence and Standardized Relative Risk (SRR) of hospitalization for unintentional fall injury, standardized for age, gender and Health Service Delivery Area (HSDA), relative to the total population of BC. We tested hypothesized associations of geographic, socio-economic, and employment-related characteristics with community SRR of injury by linear regression. During 1991 through 2010, the crude rate of hospitalization for unintentional fall injury in BC was 33.6 per 10,000 person-years. The Aboriginal rate was 49.9 per 10,000 and SRR was 1.89 (95% confidence interval 1.85-1.94). Among those living on reserves SRR was 2.00 (95% CI 1.93-2.07). Northern and non-urban HSDAs had higher SRRs, within both total and Aboriginal populations. In every age and gender category, the HSDA-standardized SRR was higher among the Aboriginal than among the total population. Between 1991 and 2010, crude rates and SRRs declined substantially, but proportionally more among the Aboriginal population, so the gap between the Aboriginal and total population is narrowing, particularly among females and older adults. These community characteristics were associated with higher risk: lower income, lower educational level, worse housing conditions, and more hazardous types of employment. Over the years, as socio-economic conditions improve, risk of hospitalization due to unintentional fall injury has declined among the Aboriginal population. Women and older adults have benefited more.

Brenner, James W.; Metz, Stacie M.; Entriken, Jack; Brenner, Christina J.

2014-01-01

Context: Alcohol-related unintentional injury (ARUI) has been an unexamined consequence of alcohol consumption by collegiate athletes. It has a potentially devastating effect on their athletic performances and careers. Awareness of this problem in athletes could have a huge effect on what athletic trainers (ATs) do to recognize, treat, and prevent it in a collegiate athlete population. Objective: To examine the experiences and attitudes among collegiate and university ATs about ARUI in the athletes in their care. Design: Cross-sectional study. Setting: Web-based survey. Patients or Other Participants: A total of 1767 e-mail addresses for collegiate and university ATs within National Athletic Trainers' Association Districts 1, 2, 3, and 9. Main Outcome Measure(s): We calculated frequencies, percentages, and attitudes of ATs regarding ARUI in collegiate athletes during the 2010–2011 academic year. Results: The resulting sample size for the analysis was 459 (26.0%) participants of the initial total sample. More than 56% (n = 260) of the ATs reported that they had evaluated, treated, or referred if needed at least 1 ARUI in a collegiate athlete. On average, these ATs had evaluated, treated, or referred if needed 3 alcohol-related unintentional injuries within the 2010–2011academic year. About 73% (n = 331) of ATs agreed that ARUI is a serious problem. Nearly 80% (n = 358) indicated they believe ATs should receive more training to identify student–athletes with alcohol-related problems. Conclusions: Alcohol-related unintentional injury is a common and serious consequence of alcohol use among collegiate athletes. Many ATs also view it as a serious problem yet would like more training in how to address it. Alcohol-related unintentional injury may have important negative effects on the careers and athletic performances of athletes. Researchers need to determine how prevalent ARUI is in the collegiate athlete population and what ATs can do to address it. PMID:24377956

The burden and pattern of unintentional child injuries in Yemen are not yet studied. This study aimed to determine the rate of unintentional injuries and their associated factors and describe the pattern of these injuries among schoolchildren in Sana'a city, Yemen. A cross-sectional school-based study was conducted among students in grades 9-12 in Sana'a Capital City. A total of 10 schools were selected using multistage sampling technique. A self-administered questionnaire was used to collect the data. A total of 1140 students (558 girls and 582 boys) participated in the study. Of all students, 550 (48.2%) students reported unintentional injuries during the last 12-months. In the multivariate analysis, boys were more likely to be injured compared to girls (OR = 1.6) and being a child of divorced or widowed parents was significantly associated with increased odds of injury (OR = 1.7). Age of the household head ≤ 45 years was associated with deceased odds of injuries (OR = 0.76). Fall was the leading cause of injury. More than half of girls (58.9%) and 30.9% of boys were injured at home. About two thirds (64.9%) of injuries affected the lower or upper extremities. One quarter of students (24.5%) received care for their injuries in outpatient clinics and 15.3% were hospitalized because of the injury. About 26.0% of injured students missed schools for one week or more. The vast majority of students (98.4%) recovered the injury while 1.6% of injuries resulted in disability. Schoolchildren in Yemen had a high rate of unintentional injuries being higher in boys and in children of divorced or widowed parents. These injuries should be recognized as a public health problem in Yemen and should be included in the Ministry of Education and Ministry of Health agenda. The reported injury mechanisms and activities posing injury risks should have implications for future interventions and awareness programs.

Ohio is experiencing unprecedented loss of life caused by unintentional drug overdoses (1), with illicitly manufactured fentanyl (IMF) emerging as a significant threat to public health (2,3). IMF is structurally similar to pharmaceutical fentanyl, but is produced in clandestine laboratories and includes fentanyl analogs that display wide variability in potency (2); variations in chemical composition of these drugs make detection more difficult. During 2010-2015, unintentional drug overdose deaths in Ohio increased 98%, from 1,544 to 3,050.* In Montgomery County (county seat: Dayton), one of the epicenters of the opioid epidemic in the state, unintentional drug overdose deaths increased 40% in 1 year, from 249 in 2015 to 349 in 2016 (estimated unadjusted mortality rate = 57.7 per 100,000) (4). IMFs have not been part of routine toxicology testing at the coroner's offices and other types of medical and criminal justice settings across the country (2,3). Thus, data on IMF test results in the current outbreak have been limited. The Wright State University and the Montgomery County Coroner's Office/Miami Valley Regional Crime Laboratory (MCCO/MVRCL) collaborated on a National Institutes of Health study of fentanyl analogs and metabolites and other drugs identified in 281 unintentional overdose fatalities in 24 Ohio counties during January-February 2017. Approximately 90% of all decedents tested positive for fentanyl, 48% for acryl fentanyl, 31% for furanyl fentanyl, and 8% for carfentanil. Pharmaceutical opioids were identified in 23% of cases, and heroin in 6%, with higher proportions of heroin-related deaths in Appalachian counties. The majority of decedents tested positive for more than one type of fentanyl. Evidence suggests the growing role of IMFs, and the declining presence of heroin and pharmaceutical opioids in unintentional overdose fatalities, compared with 2014-2016 data from Ohio and other states (3-5). There is a need to include testing for IMFs as part of standard toxicology panels for biological specimens used in the medical, substance abuse treatment, and criminal justice settings.

This study investigated the hypotheses that (i) intentional and unintentional injuries occur more frequently in areas with greater density of off-premises alcohol outlets; and (ii) larger and chain outlets selling cheaper alcohol contribute more substantially to injury risk than smaller and independent outlets. Ecological cross-sectional. From the 256 Statistical Area level 2 (SA2) census units in Melbourne, Australia, we selected a random sample of 62 units. There were 2119 Statistical Area level 1 (SA1) units nested within the selected SA2 units. The selected units contained 295 off-premises outlets. Two independent observers conducted premises assessments in all off-premises outlets, assessing the volume of alcohol available for sale (paces of shelf space), price (least wine price) and other operating characteristics (chain versus independent, drive-through). Outlet counts, assessed outlet characteristics and other area characteristics (population density, median age, median income, retail zoning) were aggregated within SA1 units. Dependent variables were counts of ambulance attended intentional injuries (assaults, stabbings, shootings) and unintentional injuries (falls, crush injuries and object strikes). In univariable analyses, chain outlets were larger (r = 0.383; P < 0.001) and sold cheaper alcohol (r = -0.484; P < 0.001) compared with independent outlets. In Bayesian spatial Poisson models, off-premises outlet density was positively related to both intentional [incidence rate ratio (IRR) = 1.38; 95% credible interval (CI) = 1.19, 1.60] and unintentional injuries (IRR = 1.18; 95% CI = 1.06, 1.30). After disaggregation by outlet characteristics, chain outlet density was also related to both intentional (IRR = 1.35; 95% CI = 1.11, 1.64) and unintentional injuries (IRR = 1.20; 95% CI = 1.08, 1.38). Greater off-premises outlet density is related to greater incidence of traumatic injury, and chain outlets appear to contribute most substantially to traumatic injury risk. © 2015 Society for the Study of Addiction.

Personal freedoms have been characterized as "positive" (freedom to pursue opportunities) and "negative" (freedom from external constraints on decision making). An ecological analysis of US data revealed a strong positive association (r = 0.41; P = .003) between state-level negative personal freedom (defined in terms of regulation of personal behavior) and state-level age-adjusted rates of unintentional injury. A conceptual emphasis on positive freedom construed as freedom to pursue a life without risk of unintentional injury could help motivate a conversation to improve public health.

Perceived intent motivates people to magnify observed harms

Ames, Daniel L.; Fiske, Susan T.

2015-01-01

Existing moral psychology research commonly explains certain phenomena in terms of a motivation to blame. However, this motivation is not measured directly, but rather is inferred from other measures, such as participants’ judgments of an agent’s blameworthiness. The present paper introduces new methods for assessing this theoretically important motivation, using tools drawn from animal-model research. We test these methods in the context of recent “harm-magnification” research, which shows that people often overestimate the damage caused by intentional (versus unintentional) harms. A preliminary experiment exemplifies this work and also rules out an alternative explanation for earlier harm-magnification results. Exp. 1 asks whether intended harm motivates blame or merely demonstrates the actor’s intrinsic blameworthiness. Consistent with a motivational interpretation, participants freely chose blaming, condemning, and punishing over other appealing tasks in an intentional-harm condition, compared with an unintentional-harm condition. Exp. 2 also measures motivation but with converging indicators of persistence (effort, rate, and duration) in blaming. In addition to their methodological contribution, these studies also illuminate people’s motivational responses to intentional harms. Perceived intent emerges as catalyzing a motivated social cognitive process related to social prediction and control. PMID:25733850

Identification of potential sewer mining locations: a Monte-Carlo based approach.

Rapid urbanization affecting demand patterns, coupled with potential water shortages due to supply side impacts of climatic changes, has led to the emergence of new technologies for water and wastewater reuse. Sewer mining (SM) is a novel decentralized option that could potentially provide non-potable water for urban uses, including for example the irrigation of urban green spaces, providing a mid-scale solution to effective wastewater reuse. SM is based on extracting wastewater from local sewers and treatment at the point of demand and entails in some cases the return of treatment residuals back to the sewer system. Several challenges are currently in the way of such applications in Europe, including public perception, inadequate regulatory frameworks and engineering issues. In this paper we consider some of these engineering challenges, looking at the sewer network as a system where multiple physical, biological and chemical processes take place. We argue that prior to implementing SM, the dynamics of the sewer system should be investigated in order to identify optimum ways of deploying SM without endangering the reliability of the system. Specifically, both wastewater extraction and sludge return could result in altering the biochemical process of the network, thus unintentionally leading to degradation of the sewer infrastructure. We propose a novel Monte-Carlo based method that takes into account both spatial properties and water demand characteristics of a given area of SM deployment while simultaneously accounting for the variability of sewer network dynamics in order to identify potential locations for SM implementation. The outcomes of this study suggest that the method can provide rational results and useful guidelines for upscale SM technologies at a city level.

Mechanization of and experience with a triplex fly-by-wire backup control system

A redundant three-axis analog control system was designed and developed to back up a digital fly-by-wire control system for an F-8C airplane. Forty-two flights, involving 58 hours of flight time, were flown by six pilots. The mechanization and operational experience with the backup control system, the problems involved in synchronizing it with the primary system, and the reliability of the system are discussed. The backup control system was dissimilar to the primary system, and it provided satisfactory handling through the flight envelope evaluated. Limited flight tests of a variety of control tasks showed that control was also satisfactory when the backup control system was controlled by a minimum-displacement (force) side stick. The operational reliability of the F-8 digital fly-by-wire control system was satisfactory, with no unintentional downmodes to the backup control system in flight. The ground and flight reliability of the system's components is discussed.

On the relation between motivation and retention in educational contexts: The role of intentional and unintentional mind wandering.

Highly motivated students often exhibit better academic performance than less motivated students. However, to date, the specific cognitive mechanisms through which motivation increases academic achievement are not well understood. Here we explored the possibility that mind wandering mediates the relation between motivation and academic performance, and additionally, we examined possible mediation by both intentional and unintentional forms of mind wandering. We found that participants reporting higher motivation to learn in a lecture-based setting tended to engage in less mind wandering, and that this decrease in mind wandering was in turn associated with greater retention of the lecture material. Critically, we also found that the influence of motivation on retention was mediated by both intentional and unintentional types of mind wandering. Not only do the present results advance our theoretical understanding of the mechanisms underlying the relation between motivation and academic achievement, they also provide insights into possible methods of intervention that may be useful in improving student retention in educational settings.

A systematic review of the literature was conducted to answer the following question: are there enhancements to standard peripartum hysterectomy technique that minimize unintentional urinary tract (UT) injury in pregnancies complicated by invasive placental attachment (INPLAT)? A PubMed search of English language articles on INPLAT published by June 2010 was conducted. Data regarding the following parameters was required for inclusion in the quantitative analysis of the review's objective: (1) type of INPLAT, (2) details pertaining to medical and surgical management of INPLAT, and (3) complications, if any, associated with management. An attempt was made to identify approaches that may lower the risk of unintentional UT injury. Most cases (285 of 292) were managed by hysterectomy. There were 83 (29%) cases of unintentional UT injury. Antenatal diagnosis of INPLAT lowered the rate of UT injury (39% vs. 63%; P = 0.04). Information regarding surgical technique or medical management was available for 90 cases; 14 of these underwent a standard hysterectomy technique. Methotrexate treatment and 11 modifications of the surgical technique were associated with 16% unintentional UT injury rate as opposed to 57% for standard hysterectomy (P = 0.002). The use of ureteral stents reduced risk of urologic injury (P = 0.01). Multiple logistic regression analysis identified antenatal diagnosis as the significant predictor of an intact UT. Antenatal diagnosis of INPLAT is paramount to minimize UT injury. Utilization of management modifications identified in this review may reduce urologic injury due to INPLAT.

Emotional responses to unintentional and intentional traumatic injuries among urban black men: A qualitative study.

The burden of injuries is disproportionately concentrated among Black men in the United States. Previous studies suggest that the mental health effects of trauma may vary by the intentionality of the injury (intentional vs. unintentional), yet little is known about this experience among Black men. We explored the emotional responses to traumatic injuries in the context of injury intentionality among Black men in an urban area. We conducted semi-structured, qualitative interviews with 74 Black men who were traumatically injured. The interviews took place three months after discharge from the hospital and they were audiotaped, transcribed, and de-identified. We used systematic thematic analysis to identify themes about post-trauma emotional responses to intentional and unintentional injuries. The narratives of intentionally injured men revealed persistent exposure to neighborhood violence and their distrust of others including the people they knew and to whom they felt close. Survivors of unintentional injuries did not express a similar distrust of others. Our findings suggest that survivors of intentional injuries experience loss of social support following their injuries. Emotional responses can differ by intentionality of traumatic injury among urban Black men. Intentional injuries may be a marker for chronic exposure to violence and limited social support for recovery. Additional resources should be targeted to survivors of intentional injury who return to disadvantaged communities after medical treatment to decrease risk of re-traumatization and adverse emotional responses.

Unintentional injury is the leading cause of death for schoolchildren. We assessed the association between externalizing psychopathology, parenting style, and unintentional injury in European children in the community. Data were drawn from the School Children Mental Health in Europe project and included 4517 schoolchildren across seven diverse European regions. Past-year injuries serious enough to seek medical attention were reported by mothers. Child mental health problems were assessed using validated measures and reported by the mothers, teachers, and children. Parenting styles were based on The Parenting Scale and the Parent Behaviors and Attitudes Questionnaire. Children with attention-deficit/hyperactivity symptoms and oppositional defiant symptoms had a higher risk of injury compared to other children whether based on parent report (OR=1.47, 95% C.I. 1.2-1.9), teacher report (OR=1.36, 95% C.I. 1.1-1.7), or parent and teacher report combined (OR=1.53, 95% C.I. 1.1-2.1). Children who self-reported oppositional symptoms also had higher risk of injury (OR=1.6, 95% C.I. 1.1-2.4). Low-caring behavior of parents increased the risk of injury (OR=1.4, 95% C.I. 1.1-1.9). Unintentional injury is a potential adverse health consequence of child externalizing problems. Interventions to improve parent-child relationships and prevention as well as focused treatment for externalizing problems may reduce the burden of injury. Copyright © 2014 Elsevier Inc.

Iron ore sintering (SNT) processes are major sources of unintentionally produced chlorinated persistent organic pollutants (POPs), including polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs), and polychlorinated naphthalenes (PCNs). However, few studies of emissions of brominated POPs, such as polybrominated dibenzo-p-dioxins/dibenzofurans (PBDD/Fs) and polybrominated diphenyl ethers (PBDEs), during SNT have been performed. Stack gas and fly ash samples from six typical SNT plants in China were collected and analyzed to determine the concentrations and profiles of PCDD/Fs, PCBs, PCNs, PBDD/Fs, and PBDEs, as well as any correlations among these compounds. The PCDD/F, PCB, PCN, PBDD/F, and PBDE emission factors were 2.47, 0.61, 552, 0.32, and 107μgt -1 , respectively (109, 4.07, 10.4, 4.41 and 0.02ng toxic equivalents t -1 , respectively). PCBs were the most abundant compounds by mass, while PCNs were the next most abundant, contributing 51% and 42% to the total POP concentration, respectively. However, PCDD/Fs were the dominant contributors to the chlorinated and brominated POP toxic equivalent concentrations, contributing 89% to the total toxic equivalent concentration. The PCDD/F and other chlorinated and brominated POP concentrations were positively correlated, indicating that chlorinated and brominated POP emissions could be synergistically decreased using the best available technologies/best environmental practices already developed for PCDD/Fs.

The extension support guiding catheter has been used to perform complex percutaneous coronary intervention to increase back-up support for the guiding catheter or to ensure deep intubation for device delivery. However, because of its monorail design, advancement of the stent into the distal extension tubing segment is sometimes problematic. Although this problem is considered due to simple collision of the stent, operators have observed tangling between a monorail extension catheter and coronary guidewire in some patients. To examine movement of the collar of the extension guide catheter during advancement of the guiding catheter, we set up an in vitro model in which the guiding catheter had two curves. Rotation of the extension guide catheter was examined by both fluoroscopic imaging and movement of the hub of the proximal end of the catheter. During advancement in the first curve, the collar moved toward the outer side of the curve of the guiding catheter as the operator pushed the shaft of the extension guiding catheter, which overrode the guidewire. After crossing the first curve, the collar moved again to the outer side of the second curve (the inner side of the first curve) of the mother catheter, and then, another clockwise rotation was observed in the proximal hub. Consequently, the collar and tubing portion of the extension guide catheter rotated 360° around the coronary guidewire, and the monorail extension catheter and guidewire became tangled. There is a potential risk of unintentional twisting with the guidewire during advancement into the curved guiding catheter because of its monorail design.

In order for nurses and other health care professionals to make important contributions to the literature, there must be an awareness of the many areas where unintentional ethical conflicts can arise. Leading ethical concerns include plagiarism, duplicate submission, authorship standards, bias, and conflicts of interest. Although many sources are available on the variety of ethical concerns, this article takes the position to identify the area of concern and describe why it is an ethical violation. Solutions are posed for resolving the conflict, including why medical librarians can help in the publishing process.

Unintentional injury is the leading cause of preventable death in children in the UK, and 0-4-year-olds frequently attend emergency departments following injuries in the home. Parenting programmes designed to support parents, promote behaviour change and enhance parent-child relationships have been shown to improve health outcomes in children. It is not known whether group-based parenting programmes have the potential to prevent unintentional injuries in preschool children. A study to develop a group-based parenting programme to prevent unintentional home injuries in preschool children, and assess the feasibility of evaluation through a cluster-randomised controlled trial. The intervention, designed for parents of children who have sustained a medically attended injury, will be developed with two voluntary sector organisations. The feasibility study will assess ability to recruit parents, deliver the programme and follow-up participants. Participants will complete questionnaires at baseline, 3 months and 6 months, and report injuries in their preschool children using a tool designed and validated for this study. Qualitative methods will assess user and deliverer perceptions of the programme. This study will develop the first group-based parenting programme to prevent injuries in preschool children, and design tools for parent-reported injury outcomes. A key challenge will be to recruit parents to participate in a manner that is non-stigmatising, and does not result in feelings of guilt or belief that they are perceived to be a bad parent. The findings will be used to prepare a trial to assess the effectiveness and cost-effectiveness of the intervention.

To assess psychological symptoms in injured children (aged 8-17 years) and their parents after emergency department (ED) care to examine the relationship between posttraumatic stress and depression symptoms, co-occurrence of symptoms within families, and the relationship of these symptoms to parent-reported overall recovery. Children and parents (n = 263 child-parent dyads) were enrolled during ED treatment for unintentional injury. Approximately 5 months later, children and parents (n = 178 dyads) completed standardized measures of posttraumatic stress and depression symptoms and parents reported on child overall recovery. Follow-up assessments found significant posttraumatic stress symptoms in 15% of children and 5% of parents, significant depression symptoms in 13% of children and 16% of parents, and problematic overall recovery in 17% of children. For both children and parents, posttraumatic stress and depression symptom severity were strongly associated. Child and parent symptoms were only modestly associated with each other, and there were few families in which both child and parent had significant posttraumatic stress or depression. Parent symptoms, but not child symptoms, were inversely associated with children's overall recovery. For about 1 in 6 children and parents, unintentional injury treated in the ED can be associated with negative psychological sequelae and suboptimal recovery. Within families, child and parent responses may differ; their relative association with overall recovery deserves additional research. To promote emotional recovery, ED clinicians should be aware of the potential psychological impact of unintentional injury, provide timely evidence-based anticipatory guidance, and communicate these concerns to primary care clinicians.

Prevalence and predictors of mental disorders in intentionally and unintentionally injured emergency centre patients

Little is known about the prevalence and predictors of mental disorders amongst injured emergency centre (EC) patients in low- and middle-income countries. Patients presenting with either an intentional or unintentional injury were recruited (n=200). Mental health, injury and psychological trauma histories were assessed. Descriptive statistics and logistic regressions were conducted and predictors for current mental disorder were identified. Diagnostic criteria for a current mental disorder, including substance use disorders, were met by 59.5% of participants. Compared to those with an unintentional injury, intentionally injured participants were more likely to be diagnosed with a current mental disorder (66.9% vs 48.8%; p=0.01). High frequencies of previous intentional injuries predicted for current mental disorder (OR = 1.460, 95% CI 1.08-1.98), while male gender and witnessed community violence predicted substance use disorder diagnoses. Findings indicate that injured EC patients, particularly those with intentional injuries, are at risk for mental disorders. Psychosocial interventions in the EC context can potentially make an important contribution in reducing the burden of mental disorders and injuries in low- and middle-income countries. PMID:25126754

This review considers barriers to, and facilitators of, success for interventions to reduce unintentional injury to children in the home through supply and/or installation of home safety equipment, and looks at risk assessments. A systematic review of qualitative research. Bibliographic databases were searched for studies on interventions to reduce unintentional child injury in the home, or on related attitudes and behaviours. Studies were quality appraised, findings extracted, and a conceptual framework was developed to assess factors affecting the success of interventions. Nine peer-reviewed journal articles were included. Barriers and facilitators were highlighted at organisational, environmental and personal levels. Effective provision of safety equipment involves ongoing support with installation and maintenance. Take up and success of interventions depends on adjusting interventions according to practical limitations and parents' cultural expectations. A particular barrier was parents' inability to modify rented or shared accommodation. The review highlights ways in which health inequalities affect the take up and success of home safety interventions, and how health workers can use this knowledge to facilitate future interventions.

Objective: The aim of this study is to compare Canadian suicide rates with other external causes of death to examine potential poisoning misclassifications as a contributor to suicide underreporting. Method: The study used Statistics Canada mortality data from 2000 to 2011 to calculate sex-and age-specific ratios by external cause of injury codes. Results: The overall Canadian suicide rate, as well as the poisoning suicide rate, declined over the study timeframe by an average annual percentage change (AAPC) of 1.0% each year. However, unintentional and undetermined poisonings increased significantly during the timeframe. Unintentional poisoning mortality (primarily narcotics and hallucinogens, including opioids) increased in proportion to suicides for both sexes, although females were consistently higher. The undetermined death to suicide ratio was higher and increasing for females. Poisonings of undetermined intent increased over time to comprise 47% to 80% of the undetermined death category for males and females combined. Conclusions: Canadian poisoning suicide rates declined, in contrast to rising unintentional and undetermined poisoning mortality rates. This trend is similar to that of the United States, supporting the hypothesis that misclassification of poisoning deaths may also be an issue in Canada.

Objectives. We aimed to analyze the epidemiology of childhood unintentional injuries presenting to hospitals in 5 select sites in low- and middle-income countries (LMICs) (Bangladesh, Colombia, Egypt, Malaysia, and Pakistan). Methods. We collected standardized data from children ages 0 to 12 years at participating emergency departments (EDs) in 2007. Statistical analyses were conducted to compare the characteristics of these injuries and to explore the determinants of injury outcomes. Results. Among 2686 injured children, falls (50.4%) and road traffic injuries (16.4%) were the most common, affecting boys more often (64.7%). Home injuries were more common among younger children (average 5.41 vs 7.06 years) and girls (38.2% vs 31.7%). Following an ED visit, 24% of injured children were admitted to the hospital, and 6 died. Injury outcomes were associated with risk factors, such as age and sex, to varying extents. Conclusions. Standardized ED surveillance revealed unintentional injuries are a threat to child health. The majority of events took place inside the home, challenging traditional concepts of children’s safety and underscoring the need for intensified context-appropriate injury prevention.

A comment on priors for Bayesian occupancy models.

PubMed

Northrup, Joseph M; Gerber, Brian D

2018-01-01

Understanding patterns of species occurrence and the processes underlying these patterns is fundamental to the study of ecology. One of the more commonly used approaches to investigate species occurrence patterns is occupancy modeling, which can account for imperfect detection of a species during surveys. In recent years, there has been a proliferation of Bayesian modeling in ecology, which includes fitting Bayesian occupancy models. The Bayesian framework is appealing to ecologists for many reasons, including the ability to incorporate prior information through the specification of prior distributions on parameters. While ecologists almost exclusively intend to choose priors so that they are "uninformative" or "vague", such priors can easily be unintentionally highly informative. Here we report on how the specification of a "vague" normally distributed (i.e., Gaussian) prior on coefficients in Bayesian occupancy models can unintentionally influence parameter estimation. Using both simulated data and empirical examples, we illustrate how this issue likely compromises inference about species-habitat relationships. While the extent to which these informative priors influence inference depends on the data set, researchers fitting Bayesian occupancy models should conduct sensitivity analyses to ensure intended inference, or employ less commonly used priors that are less informative (e.g., logistic or t prior distributions). We provide suggestions for addressing this issue in occupancy studies, and an online tool for exploring this issue under different contexts.

This study was a preliminarily investigation into the prevention of unintentional doping on the basis of self-determination theory (SDT). Specifically, we examined the relationship between athletes' motives for doping avoidance and their behavior when offered an unfamiliar food product. Participants were young Australian athletes (n = 410) that were offered a free lollipop prior to completing a questionnaire. It was noted whether participants refused to take or eat the lollipop and whether they read the ingredients of the lollipop. The questionnaire assessed autonomous and controlled forms of motivation, amotivation, doping intentions, and adherence regarding doping avoidance behaviors. The results showed that young athletes who adopted controlled reasons to avoid doping in sport (e.g., not getting caught) tended to report higher adherence to behaviors related to avoiding and monitoring banned substances, whereas those who adopted autonomous reasons (e.g., anti-doping being consistent with life goals) appeared to be more willing to read the ingredients of the provided food. The significant interaction effect between autonomous and controlled motivation indicated that autonomous motivation was more predictive to doping intention for athletes with low controlled motivation. It is concluded that SDT may help understand the motivational processes of the prevention of unintentional doping in sport. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Nanoparticles: A New Form of Terrorism?

NASA Astrophysics Data System (ADS)

Gatti, A. M.; Montanari, S.

Nanotechnologies offer numerous, very promising possibilities to solve old problems due to the matter properties at nanolevel. The opportunities presented are far-reaching, novel and unprecedented. But the enthusiasm for this revolution is tarnished by some concerns about the safety of nanoparticles for human and environment health. Their ability to negotiate the physiological barriers has already been demonstrated. The present study shows that unintentional, not engineered, nanopollution is already present in the environment, particularly because of the use of high-temperature combustion processes (internal-combustion engines, incinerators, high-technology weapons' explosion, etc.) and that presence contaminates humans, animals and environment. The paper takes into considerations public worldwide-known events where unintentional important release of nanoparticles occurred and discusses the effects that they induced in humans and animals. Biological samples affected by lymphoma, leukemia, and cancer of soft tissues of soldiers who served during the Gulf War and Balkan War and of people exposed to the 9/11 pollution are considered and specific analyses have been carried out in those pathological samples by means of Field Emission Gun Environmental Scanning Electron Microscopy coupled with an Energy Dispersive Spectroscopy. These pieces of evidence induce to consider the role of nanoparticles and their impact on the human health with attention, also for their possible terroristic use.

Self-harm is a prominent cause of morbidity in patients with bipolar disorder and is strongly associated with suicide. There is evolving evidence that lithium use may reduce suicidal behavior, in addition to concerns that the use of anticonvulsants may increase self-harm. Information is limited about the effects of antipsychotics when used as mood stabilizer treatment. Rates of unintentional injury are poorly defined in bipolar disorder, and understanding drug associations with this outcome may shed light on mechanisms for lithium's potential antisuicidal properties through reduction in impulsive aggression. To compare rates of self-harm, unintentional injury, and suicide in patients with bipolar disorder who were prescribed lithium, valproate sodium, olanzapine, or quetiapine fumarate. This investigation was a propensity score (PS)-adjusted and PS-matched longitudinal cohort study in a nationally representative UK sample using electronic health records data collected between January 1, 1995, and December 31, 2013. Participants included all patients diagnosed as having bipolar disorder who were prescribed lithium, valproate, olanzapine, or quetiapine as maintenance mood stabilizer treatment. The primary outcome was any form of self-harm. Secondary outcomes were unintentional injury and suicide. Of the 14 396 individuals with a diagnosis of BPD, 6671 were included in the cohort, with 2148 prescribed lithium, 1670 prescribed valproate, 1477 prescribed olanzapine, and 1376 prescribed quetiapine as maintenance mood stabilizer treatment. Self-harm rates were lower in patients prescribed lithium (205; 95% CI, 175-241 per 10 000 person-years at risk [PYAR]) compared with those prescribed valproate (392; 95% CI, 334-460 per 10 000 PYAR), olanzapine (409; 95% CI, 345-483 per 10 000 PYAR), or quetiapine (582; 95% CI, 489-692 per 10 000 PYAR). This association was maintained after PS adjustment (hazard ratio [HR], 1.40; 95% CI, 1.12-1.74 for valproate, olanzapine, or quetiapine vs lithium) and PS matching (HR, 1.51; 95% CI, 1.21-1.88). After PS adjustment, unintentional injury rates were lower for lithium compared with valproate (HR, 1.32; 95% CI, 1.10-1.58) and quetiapine (HR, 1.34; 95% CI, 1.07-1.69) but not olanzapine. The suicide rate in the cohort was 14 (95% CI, 9-21) per 10 000 PYAR. Although this rate was lower in the lithium group than for other treatments, there were too few events to allow accurate estimates. Patients taking lithium had reduced self-harm and unintentional injury rates. This finding augments limited trial and smaller observational study results. It supports the hypothesis that lithium use reduces impulsive aggression in addition to stabilizing mood.

Improvement of the safety of the red pepper spice with FMEA and post processing EWMA quality control charts.

Although there are numerous decades-old studies drawing attention to the presence of aflatoxins in spices, and particularly in red pepper spice, the problem has not been eradicated. In the present study, information presented in the literature, about production method of red pepper spice, its contamination with aflatoxin, and the uncertainty about the data are assessed to find out the points where improvement may be achieved. Failure Mode and Effect Analysis (FMEA) are performed to assess the risk. The highest total risk attributable to chemical plus physical plus biological causes is associated with the washing stage (RPN=363), which is followed by the receiving (RPN=342) and the storage (RPN=342) stages. The highest risk attributable to biological causes (RPN=180) is associated with microbial growth and aflatoxin production due to insufficient control of drying conditions. The highest chemical risk (RPN=144) is found for the presence of unintentional food additives, such as pesticides, herbicides, hormones, and heavy metals in fresh red pepper fruits. EWMA (exponentially weighted average) charts are employed to monitor aflatoxin production during storage. They successfully distinguished between the batches, which turned to be unsafe. Risk associated with unintentional additives may be reduced by using certified additives only. Better drying control will definitely reduce the risk associated with the drying process. Codex Alimentarius plan has worldwide acceptance for assessing safety of the nuts. Risk of accepting the batches contaminated with aflatoxin may be eliminated by applying the Codex Alimentarius sampling plan before putting the dry pulverized red pepper into the storage facility.

Two paths to blame: Intentionality directs moral information processing along two distinct tracks.

PubMed

Monroe, Andrew E; Malle, Bertram F

2017-01-01

There is broad consensus that features such as causality, mental states, and preventability are key inputs to moral judgments of blame. What is not clear is exactly how people process these inputs to arrive at such judgments. Three studies provide evidence that early judgments of whether or not a norm violation is intentional direct information processing along 1 of 2 tracks: if the violation is deemed intentional, blame processing relies on information about the agent's reasons for committing the violation; if the violation is deemed unintentional, blame processing relies on information about how preventable the violation was. Owing to these processing commitments, when new information requires perceivers to switch tracks, they must reconfigure their judgments, which results in measurable processing costs indicated by reaction time (RT) delays. These findings offer support for a new theory of moral judgment (the Path Model of Blame) and advance the study of moral cognition as hierarchical information processing.

To investigate unintentional therapeutic medication errors associated with antidepressant and antipsychotic medications in the United States and expand current knowledge on the types of errors commonly associated with these medications. A retrospective analysis of non-health care facility unintentional therapeutic errors associated with antidepressant and antipsychotic medications was conducted using data from the National Poison Data System. From 2000 to 2012, poison control centers received 207 670 calls reporting unintentional therapeutic errors associated with antidepressant or antipsychotic medications that occurred outside of a health care facility, averaging 15 975 errors annually. The rate of antidepressant-related errors increased by 50.6% from 2000 to 2004, decreased by 6.5% from 2004 to 2006, and then increased 13.0% from 2006 to 2012. The rate of errors related to antipsychotic medications increased by 99.7% from 2000 to 2004 and then increased by 8.8% from 2004 to 2012. Overall, 70.1% of reported errors occurred among adults, and 59.3% were among females. The medications most frequently associated with errors were selective serotonin reuptake inhibitors (30.3%), atypical antipsychotics (24.1%), and other types of antidepressants (21.5%). Most medication errors took place when an individual inadvertently took or was given a medication twice (41.0%), inadvertently took someone else's medication (15.6%), or took the wrong medication (15.6%). This study provides a comprehensive overview of non-health care facility unintentional therapeutic errors associated with antidepressant and antipsychotic medications. The frequency and rate of these errors increased significantly from 2000 to 2012. Given that use of these medications is increasing in the US, this study provides important information about the epidemiology of the associated medication errors.

2013-06-01

We analyzed international patterns and socioeconomic and rural-urban disparities in all-cause mortality and mortality from homicide, suicide, unintentional injuries, and HIV/AIDS among US youth aged 15-24 years. A county-level socioeconomic deprivation index and rural-urban continuum measure were linked to the 1999-2007 US mortality data. Mortality rates were calculated for each socioeconomic and rural-urban group. Poisson regression was used to derive adjusted relative risks of youth mortality by deprivation level and rural-urban residence. The USA has the highest youth homicide rate and 6th highest overall youth mortality rate in the industrialized world. Substantial socioeconomic and rural-urban gradients in youth mortality were observed within the USA. Compared to their most affluent counterparts, youth in the most deprived group had 1.9 times higher all-cause mortality, 8.0 times higher homicide mortality, 1.5 times higher unintentional-injury mortality, and 8.8 times higher HIV/AIDS mortality. Youth in rural areas had significantly higher mortality rates than their urban counterparts regardless of deprivation levels, with suicide and unintentional-injury mortality risks being 1.8 and 2.3 times larger in rural than in urban areas. However, youth in the most urbanized areas had at least 5.6 times higher risks of homicide and HIV/AIDS mortality than their rural counterparts. Disparities in mortality differed by race and sex. Socioeconomic deprivation and rural-urban continuum were independently related to disparities in youth mortality among all sex and racial/ethnic groups, although the impact of deprivation was considerably greater. The USA ranks poorly in all-cause mortality, youth homicide, and unintentional-injury mortality rates when compared with other industrialized countries.

To describe the epidemiological characteristics of unintentional injuries due to falls in children under one year and to analyse the risk factors associated with severe injuries. This multicentre, observational and cross-sectional study included all children less than one year treated for unintentional fall in the Emergency Departments of 8 Spanish Hospitals, belonging to the «Unintentional Paediatric Injury Workshop» of the Spanish Paediatric Emergency Society, between March 1st, 2014 and February 28th, 2015. Out of 289,887 emergency department cases, 1,022 were due to unintentional falls. The median age was 8 months and 52.5% were males. Fall injuries were more frequent among children aged 9-12 months (37.6%), and 83.5% occurred at home. The most common mechanism was fall from nursery equipment (69.4%), and 47.8% occurred from a height under 50cm. More than two-thirds (68%) of falls were witnessed, but in half of the cases (329) the caregiver was not in area. Serious injuries were seen in 12% of cases. In this study, a fall height greater than 50cm, falls in the street, from the arms of the carer, and from the stairs were identified as independent risk factors for worse outcomes. The most serious injuries occur in children <3 months and from a height of >50cm, though not related to unwitnessed falls. Because the most common serious injury mechanism is the fall from the arms of the carer, from stairs, and falls in the street, these facts should be highlighted in order to avoid morbidity.

Unintentional pediatric cocaine exposures are rare but concerning due to potentially serious complications such as seizures, dysrhythmias, and death. The objectives were to assess the demographic and clinical characteristics of pediatric cocaine exposures reported to the California Poison Control System. This is a retrospective study of all confirmed pediatric (< 6 years of age) cocaine exposures reported to the California Poison Control System from January 1, 1997-September 30, 2010. Case narratives were reviewed for patient demographics, exposure details, clinical effects, therapy, hospitalization, and final outcome. Of the 86 reported pediatric cocaine exposures, 36 had positive urine drug testing and were included in the study cohort. The median age at presentation was 18 months (range: 0-48 months), and 56% were male (n = 20). The most common clinical manifestations were tachycardia and seizures. The most common disposition was admission to an intensive care unit (n = 14; 39%). Eleven cases (31%) were classified as having a major effect as per American Association of Poison Control Centers case coding guidelines. One child presented in asystole with return of spontaneous circulation after cardiopulmonary resuscitation and multiple vasoactive medications. The proportion of cocaine exposures with serious (moderate or major) outcomes (66.7%; 95% confidence interval 50.3-79.8%) was higher than other pediatric poisonings reported to the American Association of Poison Control Centers during the study period (0.88%; 95% confidence interval 0.87-0.88). Although pediatric cocaine exposures are rare, they result in more severe outcomes than most unintentional pediatric poisonings. Practitioners need to be aware of the risk of recurrent seizures and cardiovascular collapse associated with cocaine poisoning. Copyright © 2017 Elsevier Inc. All rights reserved.

Describe unintentional drowning deaths in rivers, creeks and streams (rivers) in Australia and identify risk factors to inform prevention. This study is a cross-sectional, total population audit of all unintentional fatal drownings in Australian rivers between 1-July-2002 and 30-June-2012 using Australian coronial data. A modified Bonferroni test has been applied, deeming statistical significance p<0.03 and p<0.04 respectively. Rivers (n = 770; 26.6%) were the leading location among the 2,892 people who died from unintentional fatal drowning. This is a rate of 0.37/100,000 people / annum. Within river drowning deaths common groups include; males (80.4%), adults (85.3%), adults who have consumed alcohol (25.5%), people who fell in (21.3%), people involved in non-aquatic transport incidents (18.2%) and locals (74.0%). Children were 1.75 times more likely than adults (p<0.04) to drown in rivers as a result of a fall and adults 1.50 times more likely to drown in rivers as a result of watercraft incidents when compared to children. When compared to males, females were 2.27 and 4.45 times respectively more likely to drown in rivers as a result of incidents involving non-aquatic transport (p<0.04) and being swept away by floodwaters (p<0.04). Males were 2.66 and 4.27 times respectively more likely to drown in rivers as a result of watercraft incidents (p<0.04) and as a result of jumping in (p<0.04) when compared to females. While rivers are the leading location for drowning in Australia, little is understood about the risks. This study has identified key groups (males, adults, locals) and activities. While males were more likely to drown, the risk profile for females differed.

Violent death is a major public health problem in the United States and throughout the world. A cross-sectional analysis of the World Health Organization Mortality Database analyzes homicides and suicides (both disaggregated as firearm related and non-firearm related) and unintentional and undetermined firearm deaths from 23 populous high-income Organization for Economic Co-Operation and Development countries that provided data to the World Health Organization for 2003. The US homicide rates were 6.9 times higher than rates in the other high-income countries, driven by firearm homicide rates that were 19.5 times higher. For 15-year olds to 24-year olds, firearm homicide rates in the United States were 42.7 times higher than in the other countries. For US males, firearm homicide rates were 22.0 times higher, and for US females, firearm homicide rates were 11.4 times higher. The US firearm suicide rates were 5.8 times higher than in the other countries, though overall suicide rates were 30% lower. The US unintentional firearm deaths were 5.2 times higher than in the other countries. Among these 23 countries, 80% of all firearm deaths occurred in the United States, 86% of women killed by firearms were US women, and 87% of all children aged 0 to 14 killed by firearms were US children. The United States has far higher rates of firearm deaths-firearm homicides, firearm suicides, and unintentional firearm deaths compared with other high-income countries. The US overall suicide rate is not out of line with these countries, but the United States is an outlier in terms of our overall homicide rate.

To analyze published reports of unintentional cannabis ingestions in children to determine presenting signs and symptoms, route of exposure, treatment, and outcome. PubMed, OpenGrey, and Google Scholar were systematically searched. Articles were selected, reviewed, and graded using Oxford Center for Evidence-Based Medicine guidelines. Of 3316 articles, 44 were included (3582 children age ≤12 years). We found no high quality (Oxford Center for Evidence-Based Medicine level I or II) studies and 10 level III studies documenting lethargy as the most common presenting sign and confirming increasing incidence of unintentional ingestion in states having decriminalized medical and recreational cannabis. We identified 16 level IV case series, and 28 level V case reports with 114 children, mean age 25.2 ± 18.7 months, range 8 months to 12 years, and 50 female children (44%). The most common ingestion (n = 43, 38%) was cannabis resin, followed by cookies and joints (both n = 15, 13%). Other exposures included passive smoke, medical cannabis, candies, beverages, and hemp oil. Lethargy was the most common presenting sign (n = 81, 71%) followed by ataxia (n = 16, 14%). Tachycardia, mydriasis, and hypotonia were also commonly observed. All cases were cared for in the emergency department or admitted, and mean length of stay was 27.1 ± 27.0 hours. Twenty (18%) were admitted to the pediatric intensive care unit, and 7 (6%) were intubated. Unintentional cannabis ingestion by children is a serious public health concern and is well-documented in numerous studies and case reports. Clinicians should consider cannabis toxicity in any child with sudden onset of lethargy or ataxia. Copyright © 2017 Elsevier Inc. All rights reserved.

Artifact Correction in Temperature-Dependent Attenuated Total Reflection Infrared (ATR-IR) Spectra.

2017-08-01

A spectral processing method was developed and tested for analyzing temperature-dependent attenuated total reflection infrared (ATR-IR) spectra of aliphatic polyesters. Spectra of a bio-based, biodegradable polymer, 3.9 mol% 3HHx poly[(R)-3-hydroxybutyrate- co-(R)-3-hydroxyhexanoate] (PHBHx), were analyzed and corrected prior to analysis using two-dimensional correlation spectroscopy (2D-COS). Removal of the temperature variation of diamond absorbance, correction of the baseline, ATR correction, and appropriate normalization were key to generating more reliable data. Both the processing steps and order were important. A comparison to differential scanning calorimetry (DSC) analysis indicated that the normalization method should be chosen with caution to avoid unintentional trends and distortions of the crystalline sensitive bands.

We report for the first time on the growth of a homogeneous radial p-n junction in the ZnO core-shell configuration with a p-doped ZnO nanoshell structure grown around a high-quality unintentionally n-doped ZnO nanorod using sonochemistry. The simultaneous decomposition of phosphorous (P), zinc (Zn), and oxygen (O) from their respective precursors during sonication allows for the successful incorporation of P atoms into the ZnO lattice. The as-formed p-n junction shows a rectifying current-voltage characteristic that is consistent with a p-n junction with a threshold voltage of 1.3 V and an ideality factor of 33. The concentration of doping was estimated to be N A = 6.7 × 10 17 cm -3 on the p side from the capacitance-voltage measurements. The fabricated radial p-n junction demonstrated a record optical responsivity of 9.64 A/W and a noise equivalent power of 0.573 pW/√Hz under ultraviolet illumination, which is the highest for ZnO p-n junction devices.

Nutrition Management for the Head and Neck Cancer Patient.

Ackerman, Denise; Laszlo, Meghan; Provisor, Arlene; Yu, Adern

2018-01-01

Head and neck cancer (HNC) patients often face multiple nutritional challenges before, during, and after treatment due to the close proximity of the cancer to organs that are vital for normal eating function. Common treatment-related side effects, such as dysphagia, odynophagia, dysgeusia, xerostomia, thick saliva, mucositis, nausea, and vomiting, all further impair the patient's ability to maintain adequate oral intake. Malnutrition and unintentional weight loss in HNC patients during and after treatment are associated with poorer treatment outcomes, increased morbidity and mortality, and poor quality of life, even in overweight and obese patients whose Body Mass Index (BMI) is not suggestive of malnutrition. The main nutrition goal for HNC patients is thus to maximize nutrition intake either orally or through nutrition support therapy in order to prevent or limit weight loss, preserve lean body mass, minimize treatment delays and unplanned hospitalizations, and improve treatment outcomes. This chapter will discuss nutrition interventions to manage common symptoms before, during, and after treatment for HNC. Guidelines will be provided for patients that require enteral nutrition or less commonly, parenteral nutrition.

For Argument's Sake: the shadow side of argumentation and debate in the science classroom (Invited)

2013-12-01

Though the science on climate change is clear, those dismissive of current findings and future projections continue to influence the public sphere. This is never more problematic than in an educational setting, where a concern for fairness has driven the push for unscientific material to be used to balance the science. The introduction of the Next Generation Science Standards in many states across the country, which emphasizes the use of argumentation as a theme for engaging students in critical thinking, and the appeal of having students 'debate' politically controversial concepts such as climate change could unintentionally undermine the science by casting doubt and manufacturing 'controversy' where scientifically there is none. How can scientists help support teachers to use appropriate material for educating about climate change? Where is the line between supporting good science and activism? How can teachers separate the science from the politics without undermining its value in informing policy decisions? In this presentation, we will address how teachers can manage these challenges to engage students about politically and socially controversial topics while maintaining a clear, current and robust scientific basis for instruction.

Implicit working memory.

2009-09-01

Working Memory (WM) plays a crucial role in many high-level cognitive processes (e.g., reasoning, decision making, goal pursuit and cognitive control). The prevalent view holds that active components of WM are predominantly intentional and conscious. This conception is oftentimes expressed explicitly, but it is best reflected in the nature of major WM tasks: All of them are blatantly explicit. We developed two new WM paradigms that allow for an examination of the role of conscious awareness in WM. Results from five studies show that WM can operate unintentionally and outside of conscious awareness, thus suggesting that the current view should be expanded to include implicit WM.

The unintentional radiation exposure can have significant implications. We present a case of a 30-year-old pregnant female who was exposed to a potentially radioactive rock for over a one week period during her 13th week of pregnancy. After an arduous process of obtaining activity measurements, the most conservative estimate of dose, the female was exposed to, was found to fall within the permissible limits. We briefly describe the literature on fetal radiation toxicity levels and discuss logistical issues faced in managing such cases. PMID:29238629

Hypertensive Crisis From the Aquamantys Bipolar Sealing System.

Hypertension is a common occurrence during general anesthesia. Apart from pathological causes of hypertension, it is rarely extreme enough to be classified as a hypertensive crisis (systolic blood pressure >180 mm Hg or diastolic blood pressure >120 mm Hg). There is literature concerning the unintentional electrocauterization of the adrenal gland leading to hypertensive crisis, but to date, no reports have been made of adrenal stimulation from the use of an Aquamantys for hemostasis. Here, we report such a case when a hypertensive crisis (systolic blood pressure >300 mm Hg) occurred while using an Aquamantys during a liver transplant after unintentional stimulation of the adrenal glands.

The continued high mortality and morbidity rates for unintentional childhood injuries remain a public health concern. This article reports on the influence of a home visitation programme (HVP) on household hazards associated with unintentional childhood injuries in a South African low-income setting. A randomised controlled trial (n=211 households) was conducted in a South African informal settlement. Community members were recruited and trained as paraprofessional visitors. Four intervention visits were conducted over 3 months, focusing on child development, and the prevention of burn, poison, and fall injuries. The HVP, a multi-component intervention, included educational inputs, provision of safety devices, and an implicit enforcement strategy. The intervention effect (IE) was measured with a standardised risk assessment index that compared post-intervention scores for intervention and control households. A significant reduction was observed in the hazards associated with electrical and paraffin appliances, as well as in hazards related to poisoning. Non-significant changes were observed for burn safety household practices and fall injury hazards. This study confirmed that a multi-component HVP effectively reduced household hazards associated with electrical and paraffin appliances and poisoning among children in a low-income South African setting.

Arsenic exposures in Mississippi: A review of cases

DOE Office of Scientific and Technical Information (OSTI.GOV)

Park, M.J.; Currier, M.

Arsenic poisonings occur in Mississippi despite public education campaigns to prevent poisonings in the home. We reviewed 44 Mississippi cases of arsenic exposures occurring from January 1986 to May 1990. We compared the epidemiologic differences between unintentional and intentional poisonings. Cases were found and characterized through the two toxicology laboratories and hospital records. Arsenic-based rodenticides were the arsenic source in 23 of the 44 exposures. Other sources were monosodium methylarsenate (4 cases), dodecyl ammonium methane arsonate (5 cases), and other compounds (12 cases). Of the 44 exposures, 27 were unintentional, 7 were suicide attempts, 6 were homicide attempts, and 4more » were of unknown intent. Of the 27 unintentionally exposed patients, 19 were black and 14 were male; their median age was 3 years. Of the 13 intentionally poisoned persons, 9 were male and 10 were black, with a median age of 28 years. Six of the seven patients who attempted suicide were white; four of the six victims of attempted homicide were black. We recommend removal of remaining bottles of arsenic-based rodenticides from store shelves, and we urge practicing physicians to warn patients of the dangers of using such rodenticides.« less

Adherence to disease management programs in patients with COPD

The management of COPD is complex and patient adherence to treatment recommendations is known to be poor. In this paper the methods used for evaluating adherence in COPD are compared. Self-reporting has satisfactory reliability and offers a cheap, simple and easy method for assessing adherent behaviors. Unlike the objective measures of adherence such as electronic monitoring, self-reporting helps in identifying the reasons for nonadherence, which in turn would be useful in addressing adherence issues. Patients do not follow their treatment recommendations either intentionally or unintentionally. Intentional deviations are driven by patient beliefs and experiences about illness and treatment, which are in turn influenced by social and cultural factors. Unintentional deviations are often due to cognitive impairment and lack of routines. Factors associated with adherence in COPD have been explained using the Becker-Maiman model. Strategies for overcoming nonadherence have to be formulated based on the nature and reasons for nonadherence. In the event of unintentional nonadherence, the use of adherence aids like Dosette boxes, calendar packs and reminders should be promoted. Understanding patient beliefs and experiences, patient education focusing on the pathology of COPD and the role of treatment, periodic monitoring and reinforcement are critical for overcoming the barriers of intentional nonadherence.

2017-01-01

Background Unintentional weight loss (UWL) is common in older age and associated with adverse outcomes including mortality. The aim of the present study was to determine psychosocial correlates of UWL. Methods Data were derived from a large, nationally representative study of community-dwelling individuals in the second half of life (40 years and over) in Germany in 2014 (n = 7,933). Data on UWL were assessed in face-to-face interviews as unintentional loss of more than 5kg (11 pounds) in weight in the past 12 months, and data on psychosocial factors were recorded in self-administered questionnaires. Results Multiple logistic regressions revealed that UWL was positively associated with depressive symptoms and positive affect, whereas it was negatively associated with self-esteem. Individuals with UWL were more likely to feel lonely and perceive themselves as socially excluded. Conclusion The findings of important psychosocial correlates of UWL may help to identify individuals at risk for UWL in older age. This is in particular important since interventions to treat this phenomenon in older age are available that reduce adverse consequences resulting from UWL. PMID:28968437

To examine the pattern and trend of deaths due to external causes among Polish children and adolescents in 1999-2012, and to compare trends in Poland's neighboring countries. Death records were obtained from the Central Statistical Office of Poland. External causes mortality rates (MR) with 95 % confidence interval were calculated. The annual percentage change of MR was examined using linear regression. To compare MR with Belarus, Ukraine, Czech Republic and Germany, data from the European Mortality Database were used. MR were the highest in the age 15-19 years (33.7/100,000) and among boys (22.7/100,000). Unintentional injuries including transport accidents, drowning, and suicides (especially in children over 10 years old), were the main cause of death in the analyzed groups. Between 1999 and 2012 annual MR for unintentional injuries declined substantially. MR due to injuries and poisoning in Poland were higher compared with Czech Republic and Germany and lower in comparison with Belarus and Ukraine. Deaths due to unintentional injuries are still the leading cause of death among Polish children and adolescents. There are differences in death rates between Poland and neighboring countries.

We evaluated the Massachusetts Fire Safe Cigarette Law's (FSCL's) effectiveness in preventing residential fires. We examined unintentional residential fires reported to the Massachusetts Fire Incident Reporting System from 2004 to 2010. We analyzed FSCL effect on the likelihood of cigarette- versus noncigarette-caused fires and effect modification by fire scenario factors by using an interrupted time series regression model. We analyzed the effect of FSCL on monthly fire rates with Poisson regression. Cigarettes caused 1629 unintentional residential fires during the study period. The FSCL was associated with a 28% (95% confidence interval = 12%, 41%) reduction in the odds of cigarette- versus noncigarette-caused fires, although not in analyses restricted to casualty fires, with smaller sample size. The largest reductions were among fires in which human factors were involved; that were first ignited on furniture, bedding, or soft goods; that occurred in living areas; or that occurred in the summer or winter. The FSCL appears to have decreased the likelihood of cigarette-caused residential fires, particularly in scenarios for which the ignition propensity standard was developed. Current standards should be adopted, and the need for strengthening should be considered.

The authors examined the clinical characteristics of homeless patients presenting to emergency departments (EDs) in the United States, with a focus on unintentional and intentional injury events and related comorbid conditions. The study included a nationally representative sample of patients presenting to EDs with data obtained from the 2007 through 2010 National Hospital Ambulatory Medical Care Survey (NHAMCS). Descriptive and analytical epidemiologic analyses were employed to examine injuries among homeless patients. Homeless persons made 603,000 visits annually to EDs, 55% of which were for injuries, with the majority related to unintentional (52%) and self-inflicted (23%) injuries. Multivariate logistic regression analyses revealed that homeless patients had a higher odds of presenting with injuries related to unintentional (odds ratio [OR]=1.4. 95% confidence interval [CI]=1.1 to 1.9), self-inflicted (OR=6.0, 95% CI=3.7 to 9.5), and assault (OR=3.0, 95% CI=1.5 to 5.9) injuries. A better understanding of the injuries affecting homeless populations may provide medical and public health professionals insight into more effective ways to intervene and limit further morbidity and mortality related to specific injury outcomes. © 2014 by the Society for Academic Emergency Medicine.

OBJECTIVES. Child abuse is a presumed but largely untested risk factor for child homicide. This research investigated the social and child protective service history of child homicide victims. METHODS. A pairwise matched case-control design was used to assess documented child maltreatment as a risk factor for homicide vs unintentional injury death. Homicide victims aged 0 to 14 years were identified through Los Angeles Police Department case summaries. Control subjects (children who died of an unintentional injury) were matched to case subjects (children who died from homicide) by age, sex, race/ethnicity, and date of death. Case and control subjects were linked with county service records to determine any known history of maltreatment. RESULTS. A total of 220 children were homicide victims during 1978 through 1987 in the city of Los Angeles. Only one in six children who died (of homicide or unintentional injury) or his/her family was known to county social or child protective services prior to the death. Recorded history of child protective services was associated with homicide victimization (adjusted odds ratio = 3.40, 95% confidence interval = 1.25, 9.27). CONCLUSIONS. Current service systems need assistance in identifying and protecting children at high risk of homicide. PMID:8154567

Unintentional injuries are the leading cause of death among children. Previous research has shown that most of the injuries occur in and around the home. Therefore, parents have a key role in the occurrence and prevention of injuries. In this study, we examined the relationship among home injuries to children and parental attention deficit hyperactivity disorder (ADHD) symptoms, parental attitudes, and children's behavioral problems.Forty children who were admitted to the emergency department because of home injuries constitute the study group. The control group also consisted of 40 children, who were admitted for mild throat infections. The parents filled out questionnaires assessing parental ADHD, child behavioral problems, and parenting attitudes.Scores were significantly higher for both internalizing disorders and externalizing disorders in study groups. We also found that ADHD symptoms were significantly higher among fathers of injured children compared with fathers of control groups. Democratic parenting was also found to correlate with higher numbers of injuries.Parenting style, as well as the psychopathology of both the parents and children, is important factors in children's injuries. A child psychiatrist visit following an emergency procedure may help to prevent further unintentional injuries to the child.

We examined associations between sleep problems, distress intolerance, and perceived stress and health in a convenience sample of homeless adults. Participants (N = 513, 36% women, Mage = 44.5 ±11.9) self-reported sleep adequacy, sleep duration, unintentional sleep during the daytime, distress tolerance, urban stress, and days of poor mental health and days of poor physical health over the last month. The indirect effects of sleep problems on stress and health through distress tolerance were examined using a non-parametric, bias-corrected bootstrapping procedure. Sleep problems were prevalent (eg, 13.0 ±11.4 days of inadequate sleep and 4.7 ±7.9 days of unintentionally falling asleep during the preceding month). Distress intolerance partially accounted for the associations of inadequate sleep and unintentionally falling asleep, but not sleep duration, with urban stress and more days of poor mental and physical health. Many homeless individuals endure sleep problems. Given the connections between sleep and morbidity and mortality, results further support the need for more attention directed toward facilitating improvements in sleep quality to improve the quality of life of homeless adults, potentially including attention to improving distress tolerance skills.

We determine the proportion of unintended shootings that might be prevented by promoting safe storage, safe handling, and/or safer firearm designs. A regional firearm injury surveillance system was used to identify fatal and nonfatal unintentional shootings in a 5-county metropolitan area. Case reports were reviewed, and the causes of each shooting were independently classified by 4 members of the research team. A consensus conference was held to resolve disagreements. Between May 1, 1996, and June 30, 2000, 216 cases of unintentional firearm injury were identified, 3.8% of the shootings documented during the study period. Six (2.8%) were fatal. The majority of victims were between 15 and 34 years of age. One fourth (54) of the shootings involved victims younger than 18 years. Handguns were involved in 87% of the incidents. Enough information was available to characterize the incident in 122 (57%) cases. All but 6 fell into 1 or more of 3 broad categories of causation: Child access (14%), mishandling (74%), and/or deficiencies in firearm design (32%). Many unintentional shootings could be prevented by promoting safe storage of guns in the home, promoting safe handling of firearms, and requiring that all new handguns incorporate basic safety features.

Fifty Years of Physics of Living Systems.

Latash, Mark L

The equilibrium-point hypothesis and its more recent version, the referent configuration hypothesis, represent the physical approach to the neural control of action. This hypothesis can be naturally combined with the idea of hierarchical control of movements and of synergic organization of the abundant systems involved in all actions. Any action starts with defining trajectories of a few referent coordinates for a handful of salient task-specific variables. Further, referent coordinates at hierarchically lower levels emerge down to thresholds of the tonic stretch reflex for the participating muscles. Stability of performance with respect to salient variables is reflected in the structure of inter-trial variance and phenomena of motor equivalence. Three lines of recent research within this framework are reviewed. First, synergic adjustments of the referent coordinate and apparent stiffness have been demonstrated during finger force production supporting the main idea of control with referent coordinates. Second, the notion of unintentional voluntary movements has been introduced reflecting unintentional drifts in referent coordinates. Two types of unintentional movements have been observed with different characteristic times. Third, this framework has been applied to studies of impaired movements in neurological patients. Overall, the physical approach searching for laws of nature underlying biological movement has been highly stimulating and productive.

Intention and planning predicting medication adherence following coronary artery bypass graft surgery.

2014-10-01

Medication adherence rates after coronary artery bypass graft (CABG) surgery are low due to intentional (e.g., deliberately choosing not to take medication) and unintentional (e.g., forgetting to take the medication) person-related factors. There is a lack of studies examining the psychological factors related to non-adherence in CABG patients. Intentions to take medication and planning when, where, and how to take medication and to overcome unintentional forgetting to take medication were hypothesized to be independently related to medication adherence. Furthermore, planning to overcome forgetting was hypothesized to be more strongly associated with medication adherence in patients who have stronger intentions to take medication, reflecting the idea that planning is a factor that specifically helps in patients who are willing to take medication, but fail to do so. Measures of medication adherence, intention and planning were collected in a sample of (N=197) post-CABG surgery patients followed from discharge (baseline; Time 1) over a 12-month period (Time 2) in Boo-Ali Hospital in Qazvin, Iran. A series of hierarchical multiple regression analyses were performed in which medication adherence at Time 2 was regressed onto socio-demographic and clinical factors, the hypothesized psychological variables (adherence-related intention and planning), and interaction terms. Intentions to take medication (B=.30, P<.01), action planning when, where, and how to take the medication (B=.19, P<.01), and coping planning how to avoid forgetting to take the medication (B=.16, P<.01) were independently related to medication adherence. Beyond that, action planning × intention to take medication (B=.06, P<.05) and coping planning × intention (B=.07, P<.01) interaction also significantly predicted adherence. Intention to take medication was associated with better medication adherence and action and coping planning strategies to avoid forgetting to take the medication added significantly to the prediction of adherence in the year following CABG discharge. This is in line with theory and evidence about the independent roles of intentional and unintentional predictors of non-adherence. As hypothesized, planning to overcome unintentional forgetting to take the medication was more predictive of medication adherence in those patients who reported higher intentions to take medication, reflecting the idea that planning helps patients overcome unintentional reasons of being non-adherent.

A comprehensive child death review (CDR) program was introduced in England and Wales in 2008, but as yet data have only been analyzed at a local level, limiting the learning from deaths. The aim of this study is to describe the profile of causes and risk factors for sudden unexpected death in infancy (SUDI) as determined by the new CDR program. This was a descriptive outcome study using data from child death overview panel Form C for SUDI cases dying during 2010-2012 in the West Midlands region of England. The main outcome measures were: cause of death, risk factors and potential preventability of death, and determination of deaths probably due to unintentional asphyxia. Data were obtained for 65/70 (93 %) SUDI cases. 20/65 (31 %) deaths were initially categorized as due to medical causes; 21/65 (32 %) as SIDS; and 24/65 (37 %) as undetermined. Reanalysis suggested that 2/21 SIDS and 7/24 undetermined deaths were probably due to unintentional asphyxia, with 6 of these involving co-sleeping and excessive parental alcohol consumption. Deaths classified as "undetermined" had significantly higher total family and environmental risk factor scores (mean 2.6, 95 % CI 2.0-3.3) compared to those classified as SIDS (mean 1.6, 95 % CI 1.2-1.9), or medical causes for death (mean 1.1, 95 % CI 0.8-1.3). 9/20 (47 %) of medical deaths, 19/21 (90 %) SIDS, and 23/24 (96 %) undetermined deaths were considered to be potentially preventable. There were inadequacies in medical provision identified in 5/20 (25 %) of medically explained deaths. The CDR program results in detailed information about risk factors for SUDI cases but failed to recognize deaths probably due to unintentional asphyxia. The misclassification of probable unintentional asphyxial deaths and SIDS as "undetermined deaths" is likely to limit learning from these deaths and inhibit prevention strategies. Many SUDI occurred in families with mental illness, substance misuse and chaotic lifestyles and most in unsafe sleep environments. This knowledge could be used to better target safe sleep advice for vulnerable families and prevent SUDI in the future.

Plastic Beaches: occurrence and accumulation of marine debris on barrier islands in the Gulf of Mexico

Marine debris is any persistent solid material that is manufactured or processed and directly or indirectly, intentionally or unintentionally, disposed of or abandoned into the marine environment (33USC§1951). Marine debris is an economic, environmental, human health and aesthetic problem posing a complex challenge. Coastal communities are among the most seriously affected because of increased expenses for beach cleaning, public health and waste disposal, as well as a loss of income from decreased tourism. To better document this problem we are monitoring the occurrence and accumulation rate of marine debris on 6 barrier islands in the northern Gulf of Mexico (nGoM). Surveys are conducted at low tide and consist of 100m-long transects along the shoreline extending from the water edge to the upland shoreline limit. All debris larger than 5 mm is collected and recorded. Debris is then sorted by material, and dry mass is recorded. With this information we are investigating four specific questions: (1) what are the major types and possible sources (land or ocean based) of shoreline debris; (2) does the rate of debris deposition onto the shoreline show seasonal oscillations; (3) how does debris deposition change from east to west in the nGoM; and (4) what are the possible causes of the temporal and spatial trends found (e.g. rainfall and runoff, human population, boat traffic)? During the first year of sampling we are beginning to see trends emerge. More trash consistently washes up on the ocean side versus the sound side of the barrier islands, which suggests either large amounts of trash in the nGoM is ocean-based debris, or it is driven by beach goers, or both. In addition, we have found a significant increase in the amount of trash on the shoreline during tourist/boating season (May to September), although trash items tend to be smaller in size during that season. At the presentation we will discuss these and other trends that emerge with a more complete data set.

The characteristic effects of doping with impurities such as Si, Ge, Se, O, Mg, Be, and Zn on the electrical and optical properties of GaN-based materials are reviewed. In addition, the roles of unintentionally introduced impurities, such as C, H, and O, and grown-in defects, such as vacancy and antisite point defects, are also discussed. The doping process during epitaxial growth of GaN, AlGaN, InGaN, and their superlattice structures is described. Doping using the diffusion process and ion implantation techniques is also discussed. A p-n junction formed by Si implantation into p-type GaN is successfully fabricated. The results on crystal structure, electrical resistivity, carrier mobility, and optical spectra obtained by means of x-rays, low-temperature Hall measurements, and photoluminescence are also discussed.

The safety potential of lane departure warning systems-A descriptive real-world study of fatal lane departure passenger car crashes in Sweden.

2017-05-29

Lane departure crashes account for a significant proportion of passenger car occupant fatalities and serious injuries. Utilizing real-world data involving fatal passenger car crashes in Sweden, the characteristics of lane departure crashes were identified and the safety potential of lane departure warning (LDW) systems was quantified. The material consisted of 104 in-depth studies of fatal passenger car crashes in 2010. The crashes were classified as single-vehicle (n = 48), head-on (n = 52), and overtaking (n = 4) crashes. These crash types were identified as crashes that could have potentially involved lane departure. A case-by-case analysis was carried out and lane departure crashes were identified and characterized using police reports and information collected by crash investigators at the Swedish Transport Administration; for example, inspections and photographs of the crash sites and of the involved vehicles. Lane departure crashes were separated from crashes where loss of control occurred pre-lane departure. Furthermore, loss of control post-lane departures were identified. When studying the pre-stage of lane departure without prior loss of control, crashes were categorized as unintentional drifting, intentional lane change, or evasive maneuver. Using previously published effectiveness information, the potential for LDW systems to prevent crashes was estimated. Of all crashes with passenger car occupant fatalities in Sweden in 2010, 46% (63/138) were found to relate to lane departure without prior loss of control. These crashes accounted for 61% (63/104) of all single-vehicle, head-on, and overtaking crashes. The remaining 41 crashes were due to loss of control pre-lane departure. Unintentional drifting accounted for 81% (51/63) of all lane departure crashes without prior loss of control, which corresponded to 37% (51/138) of all fatal passenger car occupant crashes. LDW systems were found to potentially prevent 33-38 of the 100 fatal head-on and single vehicle crashes. These crashes involved drifting and occurred on roads with visible lane markings, signed posted speed limits ≥70 km/h, and without rumble strips on the corresponding lane departure side. The range of potentially prevented crashes (33-38) is due to the inclusion or exclusion of crashes involving excessive speeding. In this study, approximately half (51/100) of all head-on and single-vehicle crashes were identified as being a consequence of drifting, where LDW systems had the potential to prevent the majority (33-38) of these crashes. The typical lane departure crash without prior loss of control occurred on undivided roads in rural areas with signed posted speed limits ≥70 km/h, where the center and side road markings were visible.

A comment on priors for Bayesian occupancy models

PubMed Central

Gerber, Brian D.

2018-01-01

Understanding patterns of species occurrence and the processes underlying these patterns is fundamental to the study of ecology. One of the more commonly used approaches to investigate species occurrence patterns is occupancy modeling, which can account for imperfect detection of a species during surveys. In recent years, there has been a proliferation of Bayesian modeling in ecology, which includes fitting Bayesian occupancy models. The Bayesian framework is appealing to ecologists for many reasons, including the ability to incorporate prior information through the specification of prior distributions on parameters. While ecologists almost exclusively intend to choose priors so that they are “uninformative” or “vague”, such priors can easily be unintentionally highly informative. Here we report on how the specification of a “vague” normally distributed (i.e., Gaussian) prior on coefficients in Bayesian occupancy models can unintentionally influence parameter estimation. Using both simulated data and empirical examples, we illustrate how this issue likely compromises inference about species-habitat relationships. While the extent to which these informative priors influence inference depends on the data set, researchers fitting Bayesian occupancy models should conduct sensitivity analyses to ensure intended inference, or employ less commonly used priors that are less informative (e.g., logistic or t prior distributions). We provide suggestions for addressing this issue in occupancy studies, and an online tool for exploring this issue under different contexts. PMID:29481554

It has been demonstrated that motor coordination of interacting people plays a crucial role in the success of social exchanges. Abnormal movements have been reported during interpersonal interactions of patients suffering from schizophrenia and a motor coordination breakdown could explain this social interaction deficit, which is one of the main and earliest features of the illness. Using the dynamical systems framework, the goal of the current study was (i) to investigate whether social motor coordination is impaired in schizophrenia and (ii) to determine the underlying perceptual or cognitive processes that may be affected. We examined intentional and unintentional social motor coordination in participants oscillating hand-held pendulums from the wrist. The control group consisted of twenty healthy participant pairs while the experimental group consisted of twenty participant pairs that included one participant suffering from schizophrenia. The results showed that unintentional social motor coordination was preserved while intentional social motor coordination was impaired. In intentional coordination, the schizophrenia group displayed coordination patterns that had lower stability and in which the patient never led the coordination. A coupled oscillator model suggests that the schizophrenia group coordination pattern was due to a decrease in the amount of available information together with a delay in information transmission. Our study thus identified relational motor signatures of schizophrenia and opens new perspectives for detecting the illness and improving social interactions of patients. PMID:22272247

Side-wall is the static obstacle in soccer robot game, reasonably making use of the Side-wall can improve soccer robot competitive ability. As a kind of artificial life, the Side-wall processing strategy of soccer robot is influenced by many factors, such as game state, field region, attacking and defending situation and so on, each factor also has different influence degree, so, the Side-wall behavior selection is an intelligent selecting process. From the view point of human simulated, based on the idea of Side-wall processing priority[1], this paper builds the priority function for Side-wall processing, constructs the action predicative model for Side-wall obstacle, puts forward the Side-wall processing strategy, and forms the Side-wall behavior selection mechanism. Through the contrasting experiment between the strategy applied and none, proves that this strategy can improve the soccer robot capacity, it is feasible and effective, and has positive meaning for soccer robot stepped study.

A strict lifelong gluten free diet (GFD) is the only treatment for coeliac disease (CD). Theory-based research has focused predominantly on initiation, rational, and motivational processes in predicting adherence. The aim of this study was to evaluate an expanded collection of theoretical constructs specifically relevant to the maintenance of behaviour change, in the understanding and prediction of GFD adherence. Respondents with CD (N = 5573) completed measures of GFD adherence, psychological distress, intentions, self-efficacy, and the maintenance-relevant constructs of self-regulation, habit, temptation and intentional and unintentional lapses (cognitive and behavioural consequences of lowered or fluctuating psychological resources and self-control), motivation, social and environmental support, and goal priority, conflict, and facilitation. Correlations and multiple regression were used to determine their influence on adherence, over and above intention and self-efficacy, and how relationships changed in the presence of distress. Better adherence was associated with greater self-regulation, habit, self-efficacy, priority, facilitation, and support; and lower psychological distress, conflict, and fewer self-control lapses (e.g., when busy/stressed). Autonomous and wellbeing-based, but not controlled motivations, were related to adherence. In the presence of distress, the influence of self-regulation and intentional lapses on adherence were increased, while temptation and unintentional lapses were decreased. The findings point to the importance of considering intentional, volitional, automatic, and emotional processes in the understanding and prediction of GFD adherence. Behaviour change interventions and psychological support are now needed so that theoretical knowledge can be translated into evidence-based care, including a role for psychologists within the multi-disciplinary treatment team.

InGaN samples are grown using metalorganic chemical vapor deposition (MOCVD) and the dependences of structural and luminescence properties of InGaN layers on growth temperature are studied. It is found that the luminescence properties of InGaN layer are improved by increasing growth temperature properly. However, when the growth temperature of InGaN layer is too higher (740 °C in our work), a large amount of unintentionally incorporated gallium atoms enter into InGaN, and a spiral growth mode dominates in this case. It results in an inferior crystalline and interface quality, and ultimately degrades the luminescence of InGaN.

We report on a chemical free one-off imprinting method to fabricate two dimensional (2D) van der Waals (vdWs) materials based transistors. Such one-off imprinting technique is the simplest and effective way to prevent unintentional chemical reaction or damage of 2D vdWs active channel during device fabrication process. 2D MoS{sub 2} nanosheets based transistors with a hexagonal-boron-nitride (h-BN) passivation layer, prepared by one-off imprinting, show negligible variations of transfer characteristics after chemical vapor deposition process. In addition, this method enables the fabrication of all 2D MoS{sub 2} transistors consisting of h-BN gate insulator, and graphene source/drain and gate electrodes without anymore » chemical damage.« less

The stigmatization dilemma in public health policy--the case of MRSA in Denmark.

PubMed

Ploug, Thomas; Holm, Søren; Gjerris, Mickey

2015-07-11

Multi-resistant bacteria pose an increasing and significant public health risk. As awareness of the severity of the problem grows, it is likely that it will become the target for a range of public health interventions. Some of these can intentionally or unintentionally lead to stigmatization of groups of citizens. The article describes the phenomenon of stigmatization within the health care area by discussing the concept in relation to AIDS and psychiatric diagnosis. It unfolds the ethical aspects of using stigmatization as a public health instrument to affect unwanted behaviours e.g. smoking. Moreover it discusses stigmatization as an unintended albeit expected side effect of public health instruments potentially used to counter the challenge of multi-resistant bacteria with particular reference to the Danish case of the growing problems with Methicillin-resistant Staphylococcus aureus (MRSA) within pig production. We argue that using stigmatization as a direct means to achieve public health outcomes is almost always ethically illegitimate. Autonomy and dignity considerations count against it, and the cost-benefit analysis that might by some be taken to outweigh these considerations will be fundamentally uncertain. We further argue that interventions where stigmatization is a side-effect need to fulfil requirements of proportionality, and that they may fall prey to 'the stigmatization dilemma', i.e. the dilemma that arises when all policy options are potentially stigmatizing but stigmatize different groups. When this dilemma obtains the decision-maker should choose the intervention that does not lead to permanent stigmatization and that stigmatizes as few as possible, as briefly as possible, and as little as possible.

Takayasu arteritis is a granulomatous panarteritis that predominantly affects the aorta and its major branches. The initial manifestations of this large-vessel vasculitis are usually nonspecific; however, as the disease progresses, typical symptoms of arterial occlusion, aneurysmal formation, and vascular pain become evident. Ischemic ocular complications of Takayasu arteritis which could lead to complete loss of vision are not uncommon and depend on the obliterated portion(s) of carotid(s), the intensity and rate of progression of ocular vascular insufficiency, and sufficiency of the collateral blood supply to the eye. A 24-year-old woman of African descent with prior normal vision was referred to us with a 3-year history of gradual decline in visual acuity in both eyes and unintentional weight loss (17 kg) within the past 1 year. A physical examination revealed feeble brachial and radial arterial pulses on her left side. She had sinus tachycardia (136 beats/minute) and her blood pressure was 85/59 mmHg on her left and 134/82 mmHg on her right side. Bilateral microaneurysms, dot and blot hemorrhages, and multiple ischemic areas of retina together with neovascularization in her right eye were noted during a funduscopic examination. Computed tomography angiography of her thoracic and abdominal aorta revealed irregular narrowing with variable degrees of stenosis, tapering, and corrugated appearance. Despite its rarity, Takayasu arteritis significantly impairs a patient's quality of life and has a life-threatening potential. Early initiation of appropriate therapy could delay disease progression and reduce the associated complications.

We investigated the knowledge level and risk factors for pediatric unintentional burns in rural Southwest China with an aim to provide basic evidence for the prevention strategies. A stratified sampling method was used to recruit 1842 rural children from 9 schools. Self-reported burns during the past 12 months and relevant risk factors were collected by questionnaires. The burn incidence of all surveyed children was 12.7% (95% confidence interval [95% CI] 11.2–14.2%). We found that burn incidence had a trend to increase with the increasing school grade level and a trend to decrease with increasing knowledge scores on burns. The top two causes of burns were hot liquids (36.3%) and hot object (29.5%). More than 30% of children had little knowledge about preventive measures and how to give first-aid after burns. The main risk factors for burns included female gender, left-behind children by parents who were working in cities, and poor mother school education level. As the incidence of pediatric unintentional burns was high in rural southwest China, schools, families, and local public health agencies should put efforts into health education targeting burn prevention and first-aid measures after burns, particularly in “left-behind” children and those with mothers with poor education.

Objectives. We describe the burden of unintentional injury (UI) deaths among American Indian and Alaska Native (AI/AN) populations in the United States. Methods. National Death Index records for 1990 to 2009 were linked with Indian Health Service registration records to identify AI/AN deaths misclassified as non-AI/AN deaths. Most analyses were restricted to Contract Health Service Delivery Area counties in 6 geographic regions of the United States. We compared age-adjusted death rates for AI/AN persons with those for Whites; Hispanics were excluded. Results. From 2005 to 2009, the UI death rate for AI/AN people was 2.4 times higher than for Whites. Death rates for the 3 leading causes of UI death—motor vehicle traffic crashes, poisoning, and falls—were 1.4 to 3 times higher among AI/AN persons than among Whites. UI death rates were higher among AI/AN males than among females and highest among AI/AN persons in Alaska, the Northern Plains, and the Southwest. Conclusions. AI/AN persons had consistently higher UI death rates than did Whites. This disparity in overall rates coupled with recent increases in unintentional poisoning deaths requires that injury prevention be a major priority for improving health and preventing death among AI/AN populations.

Objective To identify risk factors for unintentional injuries due to falls in children aged 0–6 years. Design A systematic review of the literature. Methods Electronic databases from 1966 to March 2005 were comprehensively searched to identify empirical research that evaluated risk factors for unintentional injuries due to falls in children aged 0–6 years and included a comparison group. Results 14 studies met the inclusion criteria. Studies varied by the type of fall injury that was considered (ie, bunk bed, stairway, playground or infant walker) and with respect to the quality of evidence. In general, major risk factors for the incidence or severity of injuries due to falls in children included age of the child, sex, height of the fall, type of surface, mechanism (dropped, stairway or using a walker), setting (day care v home care) and socioeconomic status. Conclusion Despite a high burden, few controlled studies have examined the risk and protective factors for injuries due to falls in children aged 0–6 years. The only study to examine falls from a population health perspective suggests that age, sex and poverty are independent risk factors for injuries due to falls in children. PMID:17170185

To review media accounts of fatal child unintentional injury events reported in leading New Zealand newspapers for their completeness and potential to deliver evidence-based injury prevention messages. Media accounts of fatal unintentional child (0-14 years) injury events in New Zealand's four largest newspapers between 2011 and 2015 were reviewed. Variables of interest included: date, mechanism of injury and victim details. The article prominence, presence of prevention messages and case ascertainment for the two leading causes of death (2011 to 2013 only) were evaluated. Two hundred and forty-two media accounts detailing 122 fatal child injury events (133 deaths) were located for the five-year period. The most common causes of injury were transport-related (56%) and drownings (21%). Only 20% (n=49) of accounts included clear prevention messages. Just over 33% of accounts included images and 66% were located within the first three pages. Case ascertainment in the media accounts was complete for all transport deaths and all but one drowning. The low frequency of prevention messages in the media accounts reviewed highlights a missed opportunity for the dissemination of prevention messages to the New Zealand public. The findings confirm the utility of these accounts as a timely source of fatal child injury information.

Purpose Little research has been done in China to study injury in individuals with disability. We investigated impact of type and severity of disability on injury among children with disability in Hubei Province of China. Methods A sample of 1201 children with disability were matched with 1201 healthy children on gender, age, and neighborhood. Disability type and severity were determined using the Chinese national standards. Caregivers were interviewed face-to-face about nonfatal unintentional injuries suffered by the child in the past 12 months prior to the interview. Univariate Chi-square test and logistic regression models were used to investigate association between disability type/severity and nonfatal unintentional injuries. Results Injury rate among children with disability was significantly higher than that among children without disability (10.2% vs. 4.4%; P <.001). Children with multiple disabilities had the highest risk of injury after controlling for confounding variables (OR=4.54; 95% CI=2.82, 7.30; P<.001). The magnitude of the association between disability and injury varied by type and severity of disability. Conclusions The magnitude of the association between the presence or absence of disability in children and their risk of injury was large and significant, regardless of the type or severity of the children's disabilities.

US Epidemiology of Cannabis Use and Associated Problems

PubMed Central

Hasin, Deborah S

2018-01-01

This review provides an overview of the changing US epidemiology of cannabis use and associated problems. Adults and adolescents increasingly view cannabis as harmless, and some can use cannabis without harm. However, potential problems include harms from prenatal exposure and unintentional childhood exposure; decline in educational or occupational functioning after early adolescent use, and in adulthood, impaired driving and vehicle crashes; cannabis use disorders (CUD), cannabis withdrawal, and psychiatric comorbidity. Evidence suggests national increases in cannabis potency, prenatal and unintentional childhood exposure; and in adults, increased use, CUD, cannabis-related emergency room visits, and fatal vehicle crashes. Twenty-nine states have medical marijuana laws (MMLs) and of these, 8 have recreational marijuana laws (RMLs). Many studies indicate that MMLs or their specific provisions did not increase adolescent cannabis use. However, the more limited literature suggests that MMLs have led to increased cannabis potency, unintentional childhood exposures, adult cannabis use, and adult CUD. Ecological-level studies suggest that MMLs have led to substitution of cannabis for opioids, and also possibly for psychiatric medications. Much remains to be determined about cannabis trends and the role of MMLs and RMLs in these trends. The public, health professionals, and policy makers would benefit from education about the risks of cannabis use, the increases in such risks, and the role of marijuana laws in these increases.

Understanding treatment non-adherence in schizophrenia and bipolar disorder: a survey of what service users do and why

PubMed Central

2013-01-01

Background Approximately half of service users with schizophrenia or bipolar disorder do not fully follow treatment recommendations. Studies of adherence have not adequately explored the frequency, consequences and meanings of non-adherence behaviours from service users’ perspectives. This study contributes to a more fine-grained understanding of treatment choices and the support service users require in order to maximise benefit from their medications. Methods This was a mixed-methods questionnaire study, employing quantitative and thematic qualitative analyses. Thirty-five individuals with a diagnosis of, and receiving psycho-pharmaceutical treatment for, schizophrenia or bipolar disorder answered online or telephone questions about whether, how, and why they deviated from their treatment recommendations, and what support they currently and would like to receive. Results Over half of participants identified themselves as being non-adherent, however when asked in detail about intentional and unintentional adherence, 77% reported deviating from treatment recommendations. Critically, 29% were non-adherent and satisfied with being so. Service users’ satisfaction with their support was positively correlated with satisfaction with their medication. Participants’ made treatment choices in order to live well. Both side-effects and symptoms could be obstacles to adherence, but feeling well also impacted on participants’ treatment choices. Treatment choices were often made in the context of living well day-to-day, and did not necessarily take into account longer-term effects of non-adherence. Participants wanted more information about their medications, better emotional support (including better access to psychological therapies) and stability in their relationships with health professionals. Conclusions This study suggests that non-adherence, both intentional and unintentional, is common amongst individuals with diagnoses of schizophrenia and bipolar disorder, and that this often occurs without health professionals’ knowledge or support. Treatment choices reflect a desire to live well, but are often driven by short-term needs. Given access to more information, and importantly to emotional support, service users could be helped to make treatment choices that adequately reflect the long-term risks of non-adherence, as well as allowing them to live well day-to-day. More research is required better to understand the meanings and complexities of service users’ treatment choices. PMID:23714262

Findings from a qualitative research study of the context of adolescent pregnancy are presented. Participants were 21 pregnant adolescents from Medellín, Colombia, and nearby villages in the region. Data were collected by means of 21 qualitative interviews, and analysis followed grounded theory procedures. The study reveals that adolescent pregnancy occurs in the context of a "genuine love affair" in which ideas of romantic love and gender rules guide young women's behaviour. Regarding an adolescent as immature or in a process of becoming might hinder adolescents' distinctive culture and circumstances. Ideas of romantic love and gender rules were powerful influences on those who unintentionally got pregnant.

Burns are among the most common injuries affecting a great number of people worldwide annually. In Iran, especially in its western region and in Kermanshah province, burns have a relatively high incidence. The present study was aimed at investigating epidemiological characteristics in Western Iran. Within a cross-sectional study, the data on all patients attending the Burns Center at Imam Khomeini Hospital (Kermanshah, Iran) during 2010-2011 and 2011-2012 (24 months) were collected. Then, age, gender, cause of burns, total body surface area, and time of the occurrence were extracted from the hospital records. The data were analyzed using the SPSS statistical package (Version 19, for Windows). We used chi-squared test when we compared the categorical responses between two or more groups. For comparing means between two groups we used t-test. In addition, trends were investigated using linear regression. Overall 13,248 people were referred to the Burns Center at Imam Khomeini Hospital (Kermanshah, Iran) during the period of study, including 328 cases of self-immolation. The mean age of the patients was 27±19 years and 29±13 years for unintentional burns and self-immolation respectively. Out of the total number of unintentional cases, 6,519 (50.5%) were men, while the corresponding percentage of men among the self-immolation cases was 16.6% (p less than 0.001). Trends in the number of cases were cyclic, with the highest and lowest number of burns cases being in March and May. Overall, hot liquids and flammable materials were the two most important causes of unintentional burns. However, flammable materials were the main cause of burns among self-immolation cases. During hospital admission, 168 (51%) self-immolation victims and 43 (0.33%) unintentional burn victims died. While major preventive measures are not adequately used in developing countries, burns and their burden can be significantly reduced by increasing public awareness and by applying simple preventive measures. © 2014 KUMS, All rights reserved.

This article estimates percentages of U.S. emerging adults ages 18-24 engaging in past-month heavy episodic drinking and past-year alcohol-impaired driving, and numbers experiencing alcohol-related unintentional injury deaths and overdose hospitalizations between 1998 and 2014. We analyzed national injury mortality data from coroner, census, and college enrollment statistics, the National Survey on Drug Use and Health, and the Nationwide Inpatient Sample. From 1999 to 2005, percentages of emerging adults ages 18-24 reporting past-month heavy episodic drinking rose from 37.1% to 43.1% and then declined to 38.8% in 2014. Alcohol-impaired driving rose from 24% to 25.5% and then declined to 16.0%. Alcohol-related unintentional injury deaths increased from 4,807 in 1998 to 5,531 in 2005 and then declined to 4,105 in 2014, a reduction of 29% per 100,000 since 1998. Alcohol-related traffic deaths increased from 3,783 in 1998 to 4,114 in 2005 and then declined to 2,614 in 2014, down 43% per 100,000 since 1998. Alcohol-related overdose deaths increased from 207 in 1998 to 891 in 2014, a 254% increase per 100,000. Other types of nontraffic unintentional injury deaths declined. Alcohol-overdose hospitalizations rose 26% per 100,000 from 1998 to 2014, especially from increases in alcohol/other drug overdoses, up 61% (alcohol/opioid overdoses up 197%). Among emerging adults, a trend toward increased alcohol-related unintentional injury deaths, heavy episodic drinking, and alcohol-impaired driving between 1998 and 2005 was reversed by 2014. Persistent high levels of heavy episodic drinking and related problems among emerging adults underscore a need to expand individually oriented interventions, college/community collaborative programs, and evidence-supported policies to reduce their drinking and related problems.

Development and validation of a quick and easy screening tool for the early detection of undernourished residents in nursing homes and residential homes. Multi-center, cross sectional observational study. Nursing homes and residential homes. The screening tool was developed in a total of 308 residents (development sample; sample A) and cross validated in a new sample of 720 residents (validation sample) consisting of 476 nursing home residents (Sample B1) and 244 residential home residents (sample B2). Patients were defined severely undernourished when they met at least one of the following criteria: BMI or= 5% unintentional weight loss in the past month and/or >or= 10% unintentional weight loss in the past 6 months. Patients were defined as moderately undernourished if they met the following criteria: BMI 20.1-22 kg/m2 and/or 5-10% unintentional weight loss in the past six months. The most predictive questions (originally derived from previously developed screening instruments) of undernourishment were selected in sample A and cross validated in sample B. In a second stage BMI was added to the SNAQRC in sample B. The diagnostic accuracy of the screening tool in the development and validation samples was expressed in sensitivity, specificity, and the negative and positive predictive value. The four most predictive questions for undernutrition related to: unintentional weight loss more than 6 kg during the past 6 months and more than 3 kg in the past month, capability of eating and drinking with help, and decreased appetite during the past month. The diagnostic accuracy of these questions alone was insufficient (Se=45%, Sp=87%, PPV=50% and NPV=84%). However, combining the questions with measured BMI sufficiently improved the diagnostic accuracy (Se=87%, Sp=82%, PPV=59% and NPV=95%). Early detection of undernourished nursing- and residential home residents is possible using four screening questions and measured BMI.

Intentional and unintentional poisoning are among the most common reasons for referrals to emergency department (ED). Therefore, the present study was designed to evaluate epidemiologic features and effective risk factors of intentional and unintentional poisoning in children. This prospective cross-sectional study was carried out in ED of Loghman Hakim Hospital, greatest referral poison center of Iran, Tehran during March to August 2014. Demographic data, medical history, history of psychiatric disease in child, the cause of poisoning, parents' educational level, household monthly income, location of residence, history of addiction or divorce in family, and the poisoning intentionality were gathered. Data were analyzed using SPSS 18 and appropriate statistical tests based on the purpose of study. 414 participants with the mean age of 4.2 ± 3.43 years were included (57.5% male). Children in the 0-4 year(s) age range had the most frequency with 281 (67.9%) cases. 29 (7%) cases were intentional (62% female, 76% in the 10-14 years old group). Methadone with 123 (29.7%) cases was the most frequent toxic agent in general and in unintentional cases. 10-14 years of age (p = 0.001), and the history of psychiatric disease in children (p <0.001), had a direct correlation with probability of intentional poisoning. While, history of addiction in the family showed an indirect correlation with this probability (p = 0.045). Based on the results of this study, most cases of poisoning in the children were unintentional methadone intoxication in boys in the 0-4 age range with a history of a psychiatric disease, and those who had a history of addiction in the family. In addition, the most powerful risk factor for the children's intentional poisoning was their history of psychiatric disease. The history of addiction in the child's family had indirect correlation with intentional intoxications.

Injuries affect all age groups but have a particular impact on young people. To evaluate the incidence of non-fatal, unintentional, injuries among undergraduates in Wenzhou, China, assess the burden caused by these injuries, and explore the associated risk factors for unintentional injuries among these undergraduates, we conducted a college-based cross-sectional study. Participants were selected by a multi-stage random sampling method, and 2,287 students were asked whether they had had an injury in the last 12 months; the location, cause, and consequences of the event. The questionnaire included demographic and socioeconomic characteristics, lifestyle habits, and the scale of type A behaviour pattern (TABP). Multivariate logistic regression models were used; crude odds ratios (ORs), adjusted ORs and their 95% confidence intervals (CIs) were estimated, with students having no injuries as the reference group. The incidence of injuries among undergraduates in Wenzhou was 18.71 injuries per 100 person-years (95%CI: 17.12~20.31 injuries per 100 person-years). Falls were the leading cause of injury, followed by traffic injuries, and animal/insect bites. Male students were more likely to be injured than female students. Risk factors associated with unintentional injuries among undergraduates were: students majoring in non-medicine (adjusted OR: 1.53; 95% CI: 1.19-1.96); type A behaviour pattern (adjusted OR: 2.99; 95% CI: 1.45-6.14); liking sports (adjusted OR: 1.86; 95% CI: 1.41-2.45). Injuries have become a public health problem among undergraduates. Falls were the major cause of non-fatal injury. Therefore, individuals, families, schools and governments should promptly adopt preventive measures aimed at preventing and controlling morbidity due to non-fatal injury, especially among students identified to be at high-risk; such as male students with type A behaviour pattern who like sports.

Objective(s) Describe unintentional drowning deaths in rivers, creeks and streams (rivers) in Australia and identify risk factors to inform prevention. Design & Setting This study is a cross-sectional, total population audit of all unintentional fatal drownings in Australian rivers between 1-July-2002 and 30-June-2012 using Australian coronial data. A modified Bonferroni test has been applied, deeming statistical significance p<0.03 and p<0.04 respectively. Results Rivers (n = 770; 26.6%) were the leading location among the 2,892 people who died from unintentional fatal drowning. This is a rate of 0.37/100,000 people / annum. Within river drowning deaths common groups include; males (80.4%), adults (85.3%), adults who have consumed alcohol (25.5%), people who fell in (21.3%), people involved in non-aquatic transport incidents (18.2%) and locals (74.0%). Children were 1.75 times more likely than adults (p<0.04) to drown in rivers as a result of a fall and adults 1.50 times more likely to drown in rivers as a result of watercraft incidents when compared to children. When compared to males, females were 2.27 and 4.45 times respectively more likely to drown in rivers as a result of incidents involving non-aquatic transport (p<0.04) and being swept away by floodwaters (p<0.04). Males were 2.66 and 4.27 times respectively more likely to drown in rivers as a result of watercraft incidents (p<0.04) and as a result of jumping in (p<0.04) when compared to females. Conclusion(s) While rivers are the leading location for drowning in Australia, little is understood about the risks. This study has identified key groups (males, adults, locals) and activities. While males were more likely to drown, the risk profile for females differed. PMID:27517313

Children with disabilities are thought to have an increased risk of unintentional injuries, but quantitative syntheses of findings from previous studies have not been done. We conducted a systematic review and meta-analysis to assess whether pre-existing disability can increase the risk of unintentional injuries among children when they are compared to children without disability. We searched 13 electronic databases to identify original research published between 1 January 1990 and 28 February 2013. We included those studies that reported on unintentional injuries among children with pre-existing disabilities compared with children without disabilities. We conducted quality assessments and then calculated pooled odds ratios of injury using random-effects models. Fifteen eligible studies were included from 24,898 references initially identified, and there was a total sample of 83,286 children with disabilities drawn from the eligible studies. When compared with children without disabilities, the pooled OR of injury was 1.86 (95 % CI 1.65-2.10) in children with disabilities. The pooled ORs of injury were 1.28, 1.75, and 1.86 in the 0-4 years, 5-9 years, and ≥10 years of age subgroups, respectively. Compared with children without disabilities, the pooled OR was 1.75 (95 % CI 1.26-2.43) among those with International Classification of Functioning (ICF) limitations. When disability was defined as physical disabilities, the pooled OR was 2.39 (95 % CI 1.43-4.00), and among those with cognitive disabilities, the pooled OR was 1.77 (95 % CI 1.49-2.11). There was significant heterogeneity in the included studies. Compared with peers without disabilities, children with disabilities are at a significantly higher risk of injury. Teens with disabilities may be an important subgroup for future injury prevention efforts. More data are needed from low- and middle-income countries.

The objective of this study was to characterize injuries, deaths, and disabilities arising during 11 years of conflict in Baghdad. Using satellite imagery and administrative population estimated size for Baghdad, 30 clusters were selected, proportionate to population size estimates. Interviews were conducted during April and May 2014 in 900 households containing 5148 persons. Details about injuries and disabilities occurring from 2003 through May 2014 and resultant disabilities were recorded. There were 553 injuries reported by Baghdad residents, 225 of which were intentional, and 328 unintentional. For intentional injuries, the fatality rate was 39.1% and the disability rate 56.0%. Gunshots where the major cause of injury through 2006 when blasts/explosions became the most common cause and remained so through 2014. Among unintentional injuries, the fatality rate was 7.3% and the disability rate 77.1%. The major cause of unintentional injuries was falls (131) which have increased dramatically since 2008, followed by traffic related injuries (81), which have steadily increased. The proportion of injuries ending in disabilities remained fairly constant through the survey period. Intentional injuries added substantially to the burden of unintentional injuries for the population. For Baghdad, the phases of the Iraqi conflict are reflected in the patterns of injuries and consequent deaths reported. The scale of injuries during conflict is most certainly under-reported. Difficulties recalling injuries in a survey covering 11 years is a limitation, but it is likely that minor injuries were under-reported more than severe injuries. The in- and out-migration of Baghdad populations likely had effects on the events reported which we could not measure or estimate. Damage to the health infrastructure and the flight of health workers may have contributed to mortality and morbidity. Civilian injuries as well as mortality should be measured during conflicts, though not currently done.

Status and risk factors of unintentional injuries among Chinese undergraduates: a cross-sectional study

PubMed Central

2011-01-01

Background Injuries affect all age groups but have a particular impact on young people. To evaluate the incidence of non-fatal, unintentional, injuries among undergraduates in Wenzhou, China, assess the burden caused by these injuries, and explore the associated risk factors for unintentional injuries among these undergraduates, we conducted a college-based cross-sectional study. Methods Participants were selected by a multi-stage random sampling method, and 2,287 students were asked whether they had had an injury in the last 12 months; the location, cause, and consequences of the event. The questionnaire included demographic and socioeconomic characteristics, lifestyle habits, and the scale of type A behaviour pattern (TABP). Multivariate logistic regression models were used; crude odds ratios (ORs), adjusted ORs and their 95% confidence intervals (CIs) were estimated, with students having no injuries as the reference group. Results The incidence of injuries among undergraduates in Wenzhou was 18.71 injuries per 100 person-years (95%CI: 17.12~20.31 injuries per 100 person-years). Falls were the leading cause of injury, followed by traffic injuries, and animal/insect bites. Male students were more likely to be injured than female students. Risk factors associated with unintentional injuries among undergraduates were: students majoring in non-medicine (adjusted OR: 1.53; 95% CI: 1.19-1.96); type A behaviour pattern (adjusted OR: 2.99; 95% CI: 1.45-6.14); liking sports (adjusted OR: 1.86; 95% CI: 1.41-2.45). Conclusions Injuries have become a public health problem among undergraduates. Falls were the major cause of non-fatal injury. Therefore, individuals, families, schools and governments should promptly adopt preventive measures aimed at preventing and controlling morbidity due to non-fatal injury, especially among students identified to be at high-risk; such as male students with type A behaviour pattern who like sports.

Introduction Attention-deficit hyperactivity disorder (ADHD) has been related to increased rates of unintentional injuries. However, the magnitude of the effect and to which extent variables such as sex, age or comorbidity can influence this relationship is unknown. Additionally, and importantly, it is unclear if, and to which degree, ADHD medications can decrease the number of unintentional injuries. Due to the amount of economic and social resources invested in the treatment of injuries, filling these gaps in the literature is highly relevant from a public health standpoint. Here, we present a protocol for a systematic review and meta-analysis to estimate the relationship between ADHD and unintentional injuries and assess the impact of pharmacological treatment for ADHD Methods and analysis We will combine results from 114 bibliographic databases for studies relating ADHD and risk of injuries. Bibliographic searches and data extraction will be carried out independently by two researchers. The studies’ risk of bias will be assessed using the Newcastle-Ottawa Scale. Articles reporting ORs or HRs of suffering an injury in ADHD compared with controls (or enough data to calculate them) will be combined using Robust Variance Estimation, a method that permits to include multiple non-independent outcomes in the analysis. All analyses will be carried out in Stata. Age, sex and comorbid conduct disorders will be considered as potential causes of variance and their effect analysed through meta-regression and subgroup analysis. Sensitivity analyses will exclude articles with longer follow-ups, non-stringent definitions of ADHD or controls and statistically uncontrolled/controlled outcomes. Studies implementing a self-controlled case series methodology to investigate if ADHD drugs reduce the risk of injuries will be combined with a generalised linear mixed model using the Poisson distribution and a log link function.

Background. Drug overdose is an important, yet an inadequately understood, public health problem. Global attention to unintentional drug overdose has been limited by comparison with the scope of the problem. There has been a substantial increase in drug overdose incidence and prevalence in several countries worldwide over the past decade, contributing to both increased costs and mortality. Objectives. The aim of this study was to systematically synthesize the peer-reviewed literature to document the global epidemiological profile of unintentional drug overdoses and the prevalence, time trends, mortality rates, and correlates of drug overdoses. We searched different combinations of Medical Subject Headings (MeSH) terms in PubMed for articles published from 1980 until July 2013, and we organized these results in tabular spreadsheets and compared them. We restricted the search to English-language articles that deal with unintentional overdose, focusing on 1 or more of the following key constructs: prevalence, time trends, mortality rates, and correlates. The term “overdose” as a MeSH major topic yielded 1076 publications. In addition, we searched the following combinations of nonmajor MeSH terms: “street drugs” and “overdose” yielded 180, “death” and “overdose” yielded 114, and “poisoning” and “drug users” yielded 17. There was some overlap among the searches. Based on the search and inclusion and exclusion criteria, we selected a total of 169 relevant articles for this article based on a close review of abstracts. Results. We found wide variability in lifetime prevalence of experiencing a nonfatal overdose or witnessing an overdose, and in mortality rates attributable to overdose. Lifetime prevalence of witnessed overdose among drug users (n = 17 samples) ranged from 50% to 96%, with a mean of 73.3%, a median of 70%, and a standard deviation of 14.1%. Lifetime prevalence of drug users personally experiencing a nonfatal overdose (n = 27 samples), ranged from 16.6% to 68.0% with a mean of 45.4%, a median of 47%, and a standard deviation of 14.4%. Population-based crude overdose mortality rates (n = 28 samples) ranged from 0.04 to 46.6 per 100 000 person-years. This range is likely attributable to the diversity in regions, time periods, and samples. Most studies on longitudinal trends of overdose death rates or overdose-related hospitalization rates showed increases in overdose death rates and in overdose-related hospitalization rates across time, which have led to peaks in these rates at the present time. An overall trend of increasing deaths from prescription opioid use and decreasing deaths from illicit drug use in the past several years has been noted across most of the literature. With the increase in prescription opioid overdose deaths, drug overdose is not just an urban problem: rural areas have seen an important increase in overdose deaths. Lastly, cocaine, prescription opioids, and heroin are the drugs most commonly associated with unintentional drug overdoses worldwide and the demographic and psychiatric correlates associated with unintentional drug overdoses are similar globally. Conclusions. There is a need to invest in research to understand the distinct determinants of prescription drug overdose worldwide. Several other countries need to collect in a systematic and continuous fashion such data on sales of prescription opioids and other prescription drugs, nonmedical use of prescription drugs, and hospitalization secondary to overdoses on prescription drugs. The sparse evidence on the environmental determinants of overdose suggests a need for research that will inform the types of environmental interventions we can use to prevent drug overdose. Methodological issues for future studies include enhancing data collection methods on unintentional fatal and nonfatal overdoses, and collecting more detailed information on drug use history, source of drug use (for prescription drugs), and demographic and psychiatric history characteristics of the individual who overdosed.

An electrochemical process for the production of light metals, particularly aluminum. Such a process involves contacting a light metal source material with an inorganic acid to form a solution containing the light metal ions in high concentration. The solution is fed to an electrochemical reactor assembly having an anode side containing an anode and a cathode side containing a cathode, with anode side and the cathode side separated by a bipolar membrane, with the solution being fed to the anode side. Light metal ions are electrochemically transferred through the bipolar membrane to the cathode side. The process further involves reducing the light metal ions to light metal powder. An associated processing system is also provided.

Poisoning is the fifth leading cause of death from unintentional injury in the WHO European region, while Spain is in the group with a lower rate. Most involuntary poisonings occur in young children while they are at the home, due to unintentional ingestion of therapeutic drugs or household products. Of these, a large percentage is stored in non-original containers and/or within reach of children. In this article, the Committee on Safety and Non-Intentional Injury Prevention in Childhood of the Spanish Association of Pediatrics provides a series of recommendations, educational as well as legal, to prevent such cases.

Two-sided friction stir riveting (FSR) by extrusion is an innovative process developed to rapidly, efficiently, and securely join dissimilar materials. This process extends a previously developed one sided friction stir extrusion process to create a strong and robust joint by producing a continuous, rivet-like structure through a preformed hole in one of the materials with a simultaneous, two-sided friction stir spot weld. The two-sided FSR by extrusion process securely joins the dissimilar materials together and effectively locks them in place without the use of any separate materials or fasteners. Lastly, in this paper we demonstrate the process by joining aluminummore » to steel and illustrate its potential application to automotive and aerospace manufacturing processes.« less

The Presentation Location of the Reference Stimuli Affects the Left-Side Bias in the Processing of Faces and Chinese Characters

PubMed Central

Li, Chenglin; Cao, Xiaohua

2017-01-01

For faces and Chinese characters, a left-side processing bias, in which observers rely more heavily on information conveyed by the left side of stimuli than the right side of stimuli, has been frequently reported in previous studies. However, it remains unclear whether this left-side bias effect is modulated by the reference stimuli's location. The present study adopted the chimeric stimuli task to investigate the influence of the presentation location of the reference stimuli on the left-side bias in face and Chinese character processing. The results demonstrated that when a reference face was presented in the left visual field of its chimeric images, which are centrally presented, the participants showed a preference higher than the no-bias threshold for the left chimeric face; this effect, however, was not observed in the right visual field. This finding indicates that the left-side bias effect in face processing is stronger when the reference face is in the left visual field. In contrast, the left-side bias was observed in Chinese character processing when the reference Chinese character was presented in either the left or right visual field. Together, these findings suggest that although faces and Chinese characters both have a left-side processing bias, the underlying neural mechanisms of this left-side bias might be different.

Race and racism have a profound effect on our daily lives and the practice of family therapy. Whether individual or institutional level, overt or covert, intentional or unintentional, there are a variety of ways in which racism can infiltrate the therapeutic process. Before therapists can take steps to address racism effectively within the context of family therapy, it is important to attend to the development of their racial awareness and racial sensitivity. These provide the critical foundation upon which specific skills and strategies associated with effectively identifying and responding to racism in therapy are based. This article defines racial awareness and sensitivity and provides suggestions for enhancing both. In the section that follows, three major ways in which racism can infiltrate the therapeutic process are described. Skills and strategies for addressing each of these in family therapy are presented.

Stress Related Fracturing in Dimension Stone Quarries

In Missouri, the horizontal stresses (pressures) in the near surface rock are uncommonly high. While the vertical stresses in rock are simply a function of the weight of the overlying rock, near surface stresses can be many times higher. The near surface horizontal stresses can be in excess of 5 times greater than the vertical stresses. In this research, Flatjack method was used to measure horizontal stress in Red Granite Quarry in Missouri. The flat jack method is an approved method of measuring ground stresses. A saw cut is used to “relax” the stress in the ground by allowing the rock to deform inwards the cut. A hydraulic flat jack is used to inflate the slot; to push the rock back to its stressed position, as measured by a strain gauge on either side of the slot. The pressure in the jack, when the rock is exactly back to its original position, is equal to the ground stress before the saw cut was made. According to the results, present production direction for each pit is not good because the maximum stress direction is perpendicular with production direction. This case causes unintentional breakage results in the loss rock. The results show that production direction should be changed.

Sulfamethoxazole (SMX) is a commonly applied antibiotic for treating urinary tract infections; however, allergic reactions and skin eczema are known side effects that are observed for all sulfonamides. Today, this molecule is present in drinking and surface water sources. The allowed concentration in tap water is 2·10 -7  mol L -1 . SMX could unintentionally be ingested by healthy people when drinking contaminated tap water, representing unnecessary drug intake. To assess the quality of tap water, fast, specific and sensitive detection methods are required, in which consequence measures for improving the purification of water might be initiated in the short term. Herein, the quantitative detection of SMX down to environmentally and physiologically relevant concentrations in the nanomolar range by employing surface-enhanced Raman spectroscopy (SERS) and a microfluidic cartridge system is presented. By applying surface-water samples as matrices, the detection of SMX down to 2.2·10 -9  mol L -1 is achieved, which illustrates the great potential of our proposed method in environmental science.

2004-01-01

The use of Portable Electronic Devices (PEDs) onboard commercial airliners is considered to be desirable for many passengers, However, the possibility of Electromagnetic Interference (EMI) caused by these devices may affect flight safety. PEDs may act as transmitters, both intentional and unintentional, and their signals may be detected by the various navigation and communication radios onboard the aircraft. Interference Pathloss (IPL) is defined as the measurement of the radiated field coupling between passenger cabin locations and aircraft communication and navigation receivers, via their antennas. This paper first focuses on IPL measurements for GPS, taken on an out-of-service United Airlines B-737-200. IPL pattern symmetry is verified by analyzing data obtained on the windows of the Port as well as the Starboard side of the aircraft. Further graphical analysis is performed with the door and exit seams sealed with conductive tape in order to better understand the effects of shielding on IPL patterns. Shielding effects are analyzed from window data for VHF and LOC systems. In addition the shielding benefit of applying electrically conductive film to aircraft windows is evaluated for GPS and TCAS systems.

Poisoning has become the leading cause of injury death in the USA-with opioid analgesic involved in more fatal poisonings than any other drug, including cocaine and heroin. The epidemic of prescription drug poisonings is a public health concern. This study aimed to define potential high-risk groups for unintentional prescription drug poisoning by methadone, opioid analgesics, antidepressants or benzodiazepines. A hospital-based retrospective case series analysis of admissions related to prescription drug poisonings associated with methadone, opioid analgesics, antidepressants or benzodiazepines for hospitals in Clark County, Nevada between 2009 and 2013 was employed. There were 7414 admissions with a primary diagnosis of an unintentional poisoning due to methadone, opioid analgesics, antidepressants or benzodiazepines. Women had the highest rate of admissions particularly in the 45-54 age group. Higher rates of admissions were also found among non-Hispanic whites, single and uninsured populations. There were concerning increases in admissions among 65+ and Native American/Alaskan Native subgroups in 2013. Benzodiazepines and opioid analgesics were the most prevalent drug categories for prescription drug poisoning admissions. Public health professionals can utilize hospital data to identify populations at risk and in need of targeted interventions. © The Author 2016.

Weeds are a major threat to biodiversity globally degrading natural areas of high conservation value. But what are our attitudes about weeds and their management including weeds in national parks? Do we know what a weed is? Do we consider weeds a problem? Do we support their management? Are we unintentionally spreading weeds in parks? To answer these questions, we surveyed visitors entering a large popular national park near the city of Brisbane, Australia. Park visitors were knowledgeable about weeds; with >75% correctly defining weeds as 'plants that grow where they are not wanted'. About 10% of the visitors, however, provided their own sophisticated definitions. This capacity to define weeds did not vary with people's age, sex or level of education. We constructed a scale measuring visitors' overall concern about weeds in parks using the responses to ten Likert scale statements. Over 85% of visitors were concerned about weeds with older visitors, hikers, and those who could correctly define weeds more concerned than their counterparts. The majority think visitors unintentionally introduce seeds into parks, with many (63%) having found seeds on their own clothing. However, over a third disposed of these seeds in ways that could facilitate weed spread. Therefore, although most visitors were knowledgeable and concerned about weeds, and support their control, there is a clear need for more effective communication regarding the risk of visitors unintentionally dispersing weed seeds in parks.

Environmental footprint of pharmaceuticals: the significance of factors beyond direct excretion to sewers.

PubMed

Daughton, Christian G; Ruhoy, Ilene S

The combined excretion of active pharmaceutical ingredients (APIs) via urine and feces is considered the primary route by which APIs from human pharmaceuticals enter the environment. Disposal of unwanted, leftover medications by flushing into sewers has been considered a secondary route-one that does not contribute substantially to overall environmental loadings. The present study presents the first comprehensive examination of secondary routes of API release to the environment and for direct but unintentional human exposure. These include bathing, washing, and laundering, all of which release APIs remaining on the skin from the use of high-content dermal applications or from excretion to the skin via sweating, and disposal of unused and partially used high-content devices. Also discussed are the health hazards associated with: partially used devices, medication disposal practices of consumers, and interpersonal dermal transfer of API residues. Understanding these secondary routes is important from the perspective of pollution prevention, because actions can be designed more easily for reducing the environmental impact of APIs compared with the route of direct excretion (via urine and feces), for reducing the incidence of unintentional and purposeful poisonings of humans and pets, and for improving the quality and cost-effectiveness of health care. Overall, unintentional exposure to APIs for humans via these routes is possibly more important than exposure to trace residues recycled from the environment in drinking water or foods.

A systematic review with meta-analyses was performed to: 1) quantify the association between ADHD and risk of unintentional physical injuries in children/adolescents ("risk analysis"); 2) assess the effect of ADHD medications on this risk ("medication analysis"). We searched 114 databases through June 2017. For the risk analysis, studies reporting sex-controlled odds ratios (ORs) or hazard ratios (HRs) estimating the association between ADHD and injuries were combined. Pooled ORs (28 studies, 4,055,620 individuals without and 350,938 with ADHD) and HRs (4 studies, 901,891 individuals without and 20,363 with ADHD) were 1.53 (95% CI=1.40,1.67) and 1.39 (95% CI=1.06,1.83), respectively. For the medication analysis, we meta-analysed studies that avoided the confounding-by-indication bias [four studies with a self-controlled methodology and another comparing risk over time and groups (a "difference in differences" methodology)]. The pooled effect size was 0.879 (95% CI=0.838,0.922) (13,254 individuals with ADHD). ADHD is significantly associated with an increased risk of unintentional injuries and ADHD medications have a protective effect, at least in the short term, as indicated by self-controlled studies.

The objective of this study is to estimate the numbers and rate of emergency department visits in South Korea that are the result of pesticide poisoning and to describe their epidemiologic characteristics. Data collected from the National Emergency Department Information System were used to estimate the number of emergency department visits due to pesticide poisoning in South Korea for the period spanning 2006 through 2009. Emergency department visits for pesticide poisoning were defined by ICD-10 codes (T60.0-T60.9). National estimates and their 95% confidence intervals were calculated per 100 000 population. Among the 65 877 total poisoning-related emergency department visits in the data, 11 985 (18.2%) were emergency department visits resulting from pesticide poisoning. During the study period, the annual average rate of emergency department visits for pesticide poisoning was 26.8 per 100 000 population. Intentional pesticide poisoning (51.4%) was more frequent than unintentional. The fatality rate from intentional pesticide poisoning was also higher than that from unintentional or cases where the intention was unknown. In terms of age-specific rates of emergency department visits for pesticide poisoning, they increased with age, as did the gap between men and women. This study provide estimates for emergency department visits due to pesticide poisoning at the national level and suggests that pesticide poisonings, both intentional and unintentional, require significant public health interventions in South Korea.

"Violence" in medicine: necessary and unnecessary, intentional and unintentional.

PubMed

Shapiro, Johanna

2018-06-11

We are more used to thinking of medicine in relation to the ways that it alleviates the effects of violence. Yet an important thread in the academic literature acknowledges that medicine can also be responsible for perpetuating violence, albeit unintentionally, against the very individuals it intends to help. In this essay, I discuss definitions of violence, emphasizing the importance of understanding the term not only as a physical perpetration but as an act of power of one person over another. I next explore the paradox of a healing profession that is permeated with violence sometimes necessary, often unintentional, and almost always unrecognized. Identifying the construct of "physician arrogance" as contributory to violence, I go on to identify different manifestations of violence in a medical context, including violence to the body; structural violence; metaphoric violence; and the practice of speaking to or about patients (and others in the healthcare system in ways that minimize or disrespect their full humanity. I further suggest possible explanations for the origins of these kinds of violence in physicians, including the fear of suffering and death in relation to vicarious trauma and the consequent concept of "killing suffering"; as well as why patients might be willing to accept such violence directed toward them. I conclude with brief recommendations for attending to root causes of violence, both within societal and institutional structures, and within ourselves, offering the model of the wounded healer.

Injuries and violence among young people have a substantial emotional, physical, and economic toll on society. Understanding the epidemiology of this public health problem can guide prevention efforts, help identify and reduce risk factors, and promote protective factors. We examined fatal and nonfatal unintentional injuries, injuries intentionally inflicted by other (i.e., assaults and homicides) among children ages 0-19, and intentionally self-inflicted injuries (i.e., self-harm and suicides) among children ages 10-19. We accessed deaths (1999-2015) and visits to emergency departments (2001-2015) for these age groups through the Centers for Disease Control and Prevention's (CDC) Web-based Injury Statistics Query and Reporting System (WISQARS), and examined trends and differences by age, sex, race/ethnicity, rural/urban status, and injury mechanism. Almost 13,000 children and adolescents age 0-19 years died in 2015 from injury and violence compared to over 17,000 in 1999. While the overall number of deaths has decreased over time, there were increases in death rates among certain age groups for some categories of unintentional injury and for suicides. The leading causes of injury varied by age group. Our results indicate that efforts to reduce injuries to children and adolescents should consider cause, intent, age, sex, race, and regional factors to assure that prevention resources are directed at those at greatest risk.

Taking the long view: a systematic review reporting long-term perspectives on child unintentional injury.

The relative significance of child injury as a cause of preventable death has increased as mortality from infectious diseases has declined. Unintentional child injuries are now a major cause of death and disability across the world with the greatest burden falling on those who are most disadvantaged. A review of long-term data on child injury mortality was conducted to explore trends and inequalities and consider how data were used to inform policy, practice and research. The authors systematically collated and quality appraised data from publications and documents reporting unintentional child injury mortality over periods of 20 years or more. A critical narrative synthesis explored trends by country income group, injury type, age, gender, ethnicity and socioeconomic group. 31 studies meeting the inclusion criteria were identified of which 30 were included in the synthesis. Only six were from middle income countries and none were from low income countries. An overall trend in falling child injury mortality masked rising road traffic injury deaths, evidence of increasing vulnerability of adolescents and widening disparities within countries when analysed by ethnic group and socioeconomic status. Child injury mortality trend data from high and middle income countries has illustrated inequalities within generally falling trends. There is scope for greater use of existing trend data to inform policy and practice. Similar evidence from low income countries where the burden of injury is greatest is needed.

Secondary sources of information indicate that the proportion of child deaths due to injuries is increasing in Nepal. This study aimed to describe the epidemiology of unintentional injuries in children, explore risk factors and estimate the burden faced by families and the community in the Makwanpur district. We conducted a household survey in Makwanpur, covering 3441 households. Injuries that occurred during the 12 months before the survey and required treatment or caused the child to be unable to take part in usual activities for three or more days were included. We identified 193 cases of non-fatal unintentional child injuries from 181 households and estimated an annual rate of non-fatal injuries of 24.6/1000 children; rates for boys were double (32.7/1000) that for girls (16.8/1000). The rates were higher among the children of age groups 1–4 years and 5–9 years. Falls were the most common cause of non-fatal child injuries followed by burns in preschool children and road traffic injuries were the most likely cause in adolescence. Mean period of disability following injury was 25 days. The rates and the mechanisms of injury vary by age and gender. Falls and burns are currently the most common mechanisms of injury amongst young children around rural homes. PMID:26633439

Motivation, intentionality, and mind wandering: Implications for assessments of task-unrelated thought.

PubMed

2015-09-01

Researchers of mind wandering frequently assume that (a) participants are motivated to do well on the tasks they are given, and (b) task-unrelated thoughts (TUTs) that occur during task performance reflect unintentional, unwanted thoughts that occur despite participants' best intentions to maintain task-focus. Given the relatively boring and tedious nature of most mind-wandering tasks, however, there is the possibility that some participants have little motivation to do well on such tasks, and that this lack of motivation might in turn result in increases specifically in intentional TUTs. In the present study, we explored these possibilities, finding that individuals reporting lower motivation to perform well on a sustained-attention task reported more intentional relative to unintentional TUTs compared with individuals reporting higher motivation. Interestingly, our results indicate that the extent to which participants engage in intentional versus unintentional TUTs does not differentially relate to performance: both types of off-task thought were found to be equally associated with performance decrements. Participants with low levels of task-motivation also engaged in more overall TUTs, however, and this increase in TUTs was associated with greater performance decrements. We discuss these findings in the context of the literature on mind wandering, highlighting the importance of assessing the intentionality of TUTs and motivation to perform well on tasks assessing mind wandering.

Nocturnal awakenings and pediatric injury risk.

PubMed

Schwebel, David C; Brezausek, Carl M

2008-04-01

This study was designed to examine relations between nocturnal awakenings and unintentional injury risk among toddlers. A nationally representative sample of 799 children was followed longitudinally from birth through 36 months. Patterns of nocturnal awakening were assessed by parent-report at ages 6, 15, 24 and 36 months, and injury events were reported at quarterly intervals over the same time period. A range of external covariates, including positive and negative affect and externalizing behavior; maternal stress, maternal depression, and parenting style; and family socioeconomic status were measured. A persistent pattern of very mild nocturnal awakening was related to increased risk of injury during the toddler years, and that relation held after controlling for a range of potential covariates. A pattern of persistent nocturnal awakening appears to be related to unintentional injury risk in toddlers.

Mg-doped InGaN was grown on unintentionally doped GaN layer, and Mg and defect behaviours in both GaN and InGaN : Mg were investigated through photoluminescence measurement at 7 K. Mg acceptor was found in unintentionally doped GaN after thermal annealing in N2 ambient, and Mg activation energy was estimated to be 200 meV and 110 meV for GaN and InGaN, respectively. Particularly, the ultraviolet band (3.0-3.2 eV) in the GaN layer was infrequently observed in the unannealed sample but quenched in the annealed sample; this band may be associated with oxygen-substituted nitrogen defects. Moreover, the measurement errors of photoluminescence and x-ray diffraction originated from strain were taken into account.

Preferences for a potential longer-acting injectable contraceptive: perspectives from women, providers, and policy makers in Kenya and Rwanda.

Between 1995 and 2005, injectable use doubled worldwide. However, discontinuation rates remain high, partly because of side effects but also because of missed appointments for reinjection. A longer-acting injectable (LAI) may improve compliance by reducing the required number of reinjection visits, thereby reducing unintentional discontinuation. This study examined acceptability of LAI characteristics comprising the target product profile (TPP). In 2012, we conducted qualitative case studies in Kenya and Rwanda, consisting of 19 focus group discussions (FGDs) with 177 current, previous, or never users of injectables and 46 in-depth interviews (IDIs) with providers, program implementers, and policy makers. FGDs and IDIs assessed current injectable experiences; attitudes toward potential LAI products; and perceptions of TPP attributes, including ranking preferences for the most and least important characteristics. In addition, we obtained completed electronic surveys from 28 international family planning opinion leaders about the perceived need for an LAI, important product characteristics, and challenges to LAI development or introduction. Many FGD participants and interviewees spontaneously expressed strong interest in an LAI, but there was some variation in TPP preferences. The majority of participants ranked effectiveness as the most important TPP attribute. Providers were generally more concerned about side effects than potential users; some potential users suggested that side effects were related less to the product than to their own body chemistry and that side effects were acceptable as long as they did not last a long time or disrupt daily activities. Women and providers, especially in Kenya, preferred a method with a predictable return to fertility. Some participants associated amenorrhea with delayed or reduced fertility. Most women and providers preferred delivery of the LAI in a single, prepackaged, disposable injection system to facilitate injections by providers and to reduce the risk of pain or discomfort for women. While providers and policy makers ranked cost as one of the most important issues, it was among the least important issues for most potential users. Many Kenyan, but few Rwandan, participants appeared willing to pay for an LAI, with some presuming cost savings from reduced menstruation and fewer clinic visits. Some TPP preferences for an LAI have implications for product development decisions about formulation, delivery mechanism, or presentation, while others point to the need for tailored communication and counseling approaches to ensure acceptability and adherence within clinical trials and beyond.

Hormonal contraception and female pain, orgasm and sexual pleasure.

Smith, Nicole K; Jozkowski, Kristen N; Sanders, Stephanie A

Almost half of all pregnancies in the United States are unintentional, unplanned, or mistimed. Most unplanned pregnancies result from inconsistent, incorrect, or nonuse of a contraceptive method. Diminished sexual function and pleasure may be a barrier to using hormonal contraception. This study explores sexual function and behaviors of women in relation to the use of hormonal vs. nonhormonal methods of contraception. Data were collected as part of an online health and sexuality study of women. Main outcomes variables assess frequencies in two domains: (i) sexual function (proportion of sexual events with experiences of pain or discomfort, arousal, contentment and satisfaction, pleasure and enjoyment, lubrication difficulty, and orgasm) and (ii) sexual behavior (number of times engaged in sexual activity, proportion of sexual events initiated by the woman, and proportion of sexual events for which a lubricant was used). Sociodemographic variables and contraceptive use were used as sample descriptors and correlates. The recall period was the past 4 weeks. The sample included 1,101 women with approximately half (n = 535) using a hormonal contraceptive method exclusively or a combination of a hormonal and nonhormonal method, and about half (n = 566) using a nonhormonal method of contraception exclusively. Hierarchical regression analyses were conducted to examine the relation of hormonal contraceptive use to each of the dependent variables. Women using a hormonal contraceptive method experienced less frequent sexual activity, arousal, pleasure, and orgasm and more difficulty with lubrication even when controlling for sociodemographic variables. This study adds to the literature on the potential negative sexual side effects experienced by many women using hormonal contraception. Prospective research with diverse women is needed to enhance the understanding of potential negative sexual side effects of hormonal contraceptives, their prevalence, and possible mechanisms. Clinical and counseling implications are discussed. © 2013 International Society for Sexual Medicine.

Top-Down Processes Override Bottom-Up Interference in the Flanker Task.

PubMed

Avital-Cohen, Rotem; Tsal, Yehoshua

2016-05-01

Distractor interference in the flanker task is commonly viewed as an outcome of unintentional, involuntary processing, a by-product of attention-controlled processing of the target. An important implication of this notion is that the distractors are not subjected to top-down processing of their own. We tested this idea in a modified version of the flanker task, in which letter targets (S or O) were sometimes flanked by ambiguous distractors (a character that could be S or 5 or one that could be O or 0). Distractor interference was dependent on participants' expectations regarding the category of the distractors (i.e., letters or digits). For example, the O-0 distractor interfered with responding to S when it was perceived as a letter, but not when it was perceived as a digit. Hence, participants applied top-down processing to the peripheral distractors independently of the top-down processing applied to the targets. The fact that to-be-ignored peripheral distractors were processed to such a high level raises questions regarding the fundamental differences between target and distractor processing, and the quality of attentional filtering. © The Author(s) 2016.

Perceptual expertise: can sensorimotor experience change holistic processing and left-side bias?

PubMed

Tso, Ricky Van-yip; Au, Terry Kit-fong; Hsiao, Janet Hui-wen

2014-09-01

Holistic processing and left-side bias are both behavioral markers of expert face recognition. By contrast, expert recognition of characters in Chinese orthography involves left-side bias but reduced holistic processing, although faces and Chinese characters share many visual properties. Here, we examined whether this reduction in holistic processing of Chinese characters can be better explained by writing experience than by reading experience. Compared with Chinese nonreaders, Chinese readers who had limited writing experience showed increased holistic processing, whereas Chinese readers who could write characters fluently showed reduced holistic processing. This result suggests that writing and sensorimotor experience can modulate holistic-processing effects and that the reduced holistic processing observed in expert Chinese readers may depend mostly on writing experience. However, both expert writers and writers with limited experience showed similarly stronger left-side bias than novices did in processing mirror-symmetric Chinese characters; left-side bias may therefore be a robust expertise marker for object recognition that is uninfluenced by sensorimotor experience. © The Author(s) 2014.

Attention-deficit hyperactivity disorder (ADHD) has been related to increased rates of unintentional injuries. However, the magnitude of the effect and to which extent variables such as sex, age or comorbidity can influence this relationship is unknown. Additionally, and importantly, it is unclear if, and to which degree, ADHD medications can decrease the number of unintentional injuries. Due to the amount of economic and social resources invested in the treatment of injuries, filling these gaps in the literature is highly relevant from a public health standpoint. Here, we present a protocol for a systematic review and meta-analysis to estimate the relationship between ADHD and unintentional injuries and assess the impact of pharmacological treatment for ADHD METHODS AND ANALYSIS: We will combine results from 114 bibliographic databases for studies relating ADHD and risk of injuries. Bibliographic searches and data extraction will be carried out independently by two researchers. The studies' risk of bias will be assessed using the Newcastle-Ottawa Scale. Articles reporting ORs or HRs of suffering an injury in ADHD compared with controls (or enough data to calculate them) will be combined using Robust Variance Estimation, a method that permits to include multiple non-independent outcomes in the analysis. All analyses will be carried out in Stata. Age, sex and comorbid conduct disorders will be considered as potential causes of variance and their effect analysed through meta-regression and subgroup analysis. Sensitivity analyses will exclude articles with longer follow-ups, non-stringent definitions of ADHD or controls and statistically uncontrolled/controlled outcomes. Studies implementing a self-controlled case series methodology to investigate if ADHD drugs reduce the risk of injuries will be combined with a generalised linear mixed model using the Poisson distribution and a log link function.

Risk factors for unintentional poisoning in children aged 1-3 years in NSW Australia: a case-control study.

PubMed

Schmertmann, Marcia; Williamson, Ann; Black, Deborah; Wilson, Leigh

2013-05-24

Unintentional poisoning in young children is an important public health issue. Age pattern studies have demonstrated that children aged 1-3 years have the highest levels of poisoning risk among children aged 0-4 years, yet little research has been conducted regarding risk factors specific to this three-year age group and the methodologies employed varied greatly. The purpose of the current study is to investigate a broad range of potential risk factors for unintentional poisoning in children aged 1-3 years using appropriate methodologies. Four groups of children, one case group (children who had experienced a poisoning event) and three control groups (children who had been 'injured', 'sick' or who were 'healthy'), and their mothers (mother-child dyads) were enrolled into a case-control study. All mother-child dyads participated in a 1.5-hour child developmental screening and observation, with mothers responding to a series of questionnaires at home. Data were analysed as three case-control pairs with multivariate analyses used to control for age and sex differences between child cases and controls. Five risk factors were included in the final multivariate models for one or more case-control pairs. All three models found that children whose mothers used more positive control in their interactions during a structured task had higher odds of poisoning. Two models showed that maternal psychiatric distress increased poisoning risk (poisoning-injury and poisoning-healthy). Individual models identified the following variables as risk factors: less proximal maternal supervision during risk taking activities (poisoning-injury), medicinal substances stored in more accessible locations in bathrooms (poisoning-sick) and lower total parenting stress (poisoning-healthy). The findings of this study indicate that the nature of the caregiver-child relationship and caregiver attributes play an important role in influencing poisoning risk. Further research is warranted to explore the link between caregiver-child relationships and unintentional poisoning risk. Caregiver education should focus on the benefits of close interaction with their child as a prevention measure.

Objectives To describe the incidences and causes of occupational police deaths in New York City in the United States and Greater London in the United Kingdom during the twentieth century. To assess the relation between overall societal violence and violence directed toward police officers in these metropolitan areas. Design and setting Ecological study of New York and London from 1900 through 1999. Main outcome measures Intentional and unintentional occupational police mortality rates for New York and London were estimated for each decade. The general population homicide rates of both New York and London were assessed for their correlation with their respective intentional occupational police mortality rates. Results During the 20th century, 585 police officers in New York and 160 police officers in London died while participating in law enforcement activities. New York had markedly greater intentional police mortality rates compared to London throughout most of the 20th century, but these differences decreased significantly by the end of the century. Intentional gunshot wounds comprised 290 police deaths in New York, but only 14 police deaths in London. In New York, gun shot wounds (both intentional and unintentional) accounted for more occupational police deaths (51.6%) than did all other injury mechanisms combined. In London, motor vehicle collision was the most common cause (47.5%) of occupational police death. There were no apparent correlations between the general population homicide rates and intentional police mortality rates in either New York (r2 = 0.05, 95% CI −0.77 to 0.81) or London (r2 = 0.34, 95% CI −0.61 to 0.89). Conclusions During the 20th century, both intentional and unintentional occupational police mortality rates were significantly greater in New York compared to London. These differences are likely from several socioeconomic, cultural, and occupational factors. The declines in police deaths in New York during the latter part of the 20th century indicate that at least some measures taken by the New York Police Department have been successful at significantly reducing the incidence of both intentional and unintentional police deaths.

Childhood unintentional injuries are perceived as a leading public health issue since they are one of the preventable causes of paediatric mortality and morbidity. Whether and how parental factors are related to childhood injury has been researched insufficiently. To investigate parents' attitudes to preventive measures of unintentional childhood injury, and the parental adherence to these measures. Cross-sectional, descriptive study. The data were collected from the parents of children younger than ten years of age admitted to university hospital outpatient clinics for any reason and who agreed to be involved in the study. The first part of the questionnaire included sociodemographic profiles of participating children. Serious injuries were considered to be any injury that requires hospital admission. The second part of the questionnaire was prepared to evaluate parents' adherence to injury prevention rules. A total score calculation about the adherence of the parents to the injury prevention rules was worked out the addition of the scores of each answer given in each age group. Answers for each item given by the parents were scored as wrong (0), sometimes (1) or correct (2). The score for each item was added and the result normalized to 100 points. Only complete questionnaires were used for analysis. A total of 1126 children and parent pairs agreed to participate in the survey. It was found that 13.8% of the participating children had experienced at least one serious injury. Although three-quarters of the parents had received information about injury prevention, the overall injury prevention scores were found to be low. As children's age increased, the total injury prevention scores of parents decreased significantly. Injury prevention scores were shown to increase significantly with high education and maternal occupation. However, scores were shown to decrease significantly with increased child age and family size. Our study shows that parental adherence to the child safety measures aimed at decreasing the unintentional injury risk of children is not satisfactory in Turkey. In particular, parents of 5-9-year-old children, big families (more than five people), parents with less than 8 years of education and non-working mothers should be the main target groups for intervention strategies according to our study results.

Objective Left ventricular (LV) function and dyssynchrony parameters measured from serial gated single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) using blinded processing had a poorer repeatability than when manual side-by-side processing was used. The objective of this study was to validate whether an automatic alignment tool can reduce the variability of LV function and dyssynchrony parameters in serial gated SPECT MPI. Methods Thirty patients who had undergone serial gated SPECT MPI were prospectively enrolled in this study. Thirty minutes after the first acquisition, each patient was repositioned and a gated SPECT MPI image was reacquired. The two data sets were first processed blinded from each other by the same technologist in different weeks. These processed data were then realigned by the automatic tool, and manual side-by-side processing was carried out. All processing methods used standard iterative reconstruction and Butterworth filtering. The Emory Cardiac Toolbox was used to measure the LV function and dyssynchrony parameters. Results The automatic tool failed in one patient, who had a large, severe scar in the inferobasal wall. In the remaining 29 patients, the repeatability of the LV function and dyssynchrony parameters after automatic alignment was significantly improved from blinded processing and was comparable to manual side-by-side processing. Conclusion The automatic alignment tool can be an alternative method to manual side-by-side processing to improve the repeatability of LV function and dyssynchrony measurements by serial gated SPECT MPI.

Harnessing the wandering mind: the role of perceptual load.

PubMed

Forster, Sophie; Lavie, Nilli

2009-06-01

Perceptual load is a key determinant of distraction by task-irrelevant stimuli (e.g., Lavie, N. (2005). Distracted and confused?: Selective attention under load. Trends in Cognitive Sciences, 9, 75-82). Here we establish the role of perceptual load in determining an internal form of distraction by task-unrelated thoughts (TUTs or "mind-wandering"). Four experiments demonstrated reduced frequency of TUTs with high compared to low perceptual load in a visual-search task. Alternative accounts in terms of increased demands on responses, verbal working memory or motivation were ruled out and clear effects of load were found for unintentional TUTs. Individual differences in load effects on internal (TUTs) and external (response-competition) distractors were correlated. These results suggest that exhausting attentional capacity in task-relevant processing under high perceptual load can reduce processing of task-irrelevant information from external and internal sources alike.

The Automaticity of Emotional Face-Context Integration

2011-01-01

Recent studies have demonstrated that context can dramatically influence the recognition of basic facial expressions, yet the nature of this phenomenon is largely unknown. In the present paper we begin to characterize the underlying process of face-context integration. Specifically, we examine whether it is a relatively controlled or automatic process. In Experiment 1 participants were motivated and instructed to avoid using the context while categorizing contextualized facial expression, or they were led to believe that the context was irrelevant. Nevertheless, they were unable to disregard the context, which exerted a strong effect on their emotion recognition. In Experiment 2, participants categorized contextualized facial expressions while engaged in a concurrent working memory task. Despite the load, the context exerted a strong influence on their recognition of facial expressions. These results suggest that facial expressions and their body contexts are integrated in an unintentional, uncontrollable, and relatively effortless manner. PMID:21707150

Is cognitive control automatic? New insights from transcranial magnetic stimulation.

PubMed

Cona, G; Treccani, B; Umiltà, C A

2016-10-01

Cognitive control has been classically considered as a flexible process engaged to pursue intentional behaviors, as distinct from automatic processes, which are unintentional, inflexible, and triggered by unconscious mechanisms. Our study challenged this view, showing that such a distinction may not be so clear-cut. We analyzed motor-evoked potentials (MEPs) elicited by transcranial magnetic stimulation to investigate the neurocognitive mechanisms occurring in a conflict task during trials that either required or did not require a response. We observed a Simon effect on MEPs and sequential modulations of such effects on both kinds of trials. Sequential modulations are usually explained as resulting from the engagement of intentional control mechanisms. Our findings rule against this idea, suggesting that these effects are the result of a mechanism that detects and resolves conflict even when there is no intention to select any response. Accordingly, cognitive control also seems to operate without intention, acting in an automatic fashion.

Fatal chlorine gas exposure at a metal recycling facility: Case report.

PubMed

Harvey, Robert R; Boylstein, Randy; McCullough, Joel; Shumate, Alice; Yeoman, Kristin; Bailey, Rachel L; Cummings, Kristin J

2018-06-01

At least four workers at a metal recycling facility were hospitalized and one died after exposure to chlorine gas when it was accidentally released from an intact, closed-valved cylinder being processed for scrap metal. This unintentional chlorine gas release marks at least the third such incident at a metal recycling facility in the United States since 2010. We describe the fatal case of the worker whose clinical course was consistent with acute respiratory distress syndrome (ARDS) following exposure to high concentrations of chlorine gas. This case report emphasizes the potential risk of chlorine gas exposure to metal recycling workers by accepting and processing intact, closed-valved containers. The metal recycling industry should take steps to increase awareness of this established risk to prevent future chlorine gas releases. Additionally, public health practitioners and clinicians should be aware that metal recycling workers are at risk for chlorine gas exposure. © 2018 Wiley Periodicals, Inc.

Comparison of light and x-ray sensitometric responses of double-emulsion films for different processing conditions.

PubMed

Blendl, C; Buhr, E

2001-12-01

The effects of different film processing conditions on light and x-ray sensitometric responses were compared for a variety of double-emulsion x-ray films. The processing conditions were altered by changes of the developer temperature. Three different exposure variants were applied: x-ray sensitometry using two stepped neutral density attenuators between film and screens, simultaneous double-sided light sensitometry, and single-sided light sensitometry. 13 different types of double-emulsion x-ray films were investigated, among them three asymmetric films. In the special case of exposing the asymmetric films with the single-sided light sensitometer, a method was investigated where each side of the film is exposed at different locations and the sum effect is analyzed. From each sensitometric curve shape two parameters, the logarithmic speed (logS) and the average gradient (G), were evaluated. The results of this study can be summarized as follows: (1) Single-sided and double-sided light sensitometers revealed almost equal changes of logS when the processing conditions are altered. Thus, single-sided light sensitometers can serve as a substitute for double-sided light sensitometers provided that suited exposure methods are used and appropriate sensitometric parameters are evaluated. (2) Light sensitometry quantitatively indicated changes of the film processing that affect the x-ray speed. Hence, light sensitometry is a useful method to monitor changes in film processing.

Si impurity concentration in nominally undoped Al0.7Ga0.3N grown in a planetary MOVPE reactor

2018-02-01

The unintentional silicon incorporation during the metalorganic vapor phase epitaxy (MOVPE) of nominally undoped Al0.7Ga0.3N in a Planetary Reactor under various growth conditions was investigated. Dependent on growth temperature, pressure and V/III ratio, Si concentrations of below 1 × 1016 up to 4 × 1017 cm-3 were measured. Potential Si sources are discussed and, by comparing samples grown in a SiC coated reactor setup and in a TaC coated setup, the SiC coatings in the reactor are identified as the most likely source for the unintentional Si doping at elevated temperatures above 1080 °C. Under identical growth conditions the background Si concentration can be reduced by up to an order of magnitude when using TaC coatings.

Mothers' supervision and perception of young children's risk of unintentional injury in the home.

PubMed

Gärling, A; Gärling, T

1993-02-01

Investigated whether control exerted through supervision is believed by mothers to reduce risk of unintentional injury to their children. 150 mothers of 1-, 2-, and 3-year-old children rated the risk of their child having an injury and indicated what injuries they anticipated in different rooms of the home under four conditions of supervision. A clear effect of supervision was observed in that rated risk and the number of anticipated injuries decreased depending on whether the mother was in the same room or not. Furthermore, a decrease was found when the mother was in the same room engaged in the same activity as the child (either playing with or being assisted by the child). The observed effects of supervision were less strong for older children and for rooms perceived as less dangerous.

Perceptions of intentional wrongdoing and peer reporting behavior among registered nurses.

PubMed

King, G

2001-11-01

How a person perceives a wrongdoing being committed by a coworker will affect whether the incident is reported within the organization. A significant factor that may influence the decision to report a wrongdoing is the perceived intentionality of the wrongdoer. This study sought to examine if differences in perceptions of a wrongdoing could affect the disclosure of unethical behavior. Three hundred seventy-two registered nurses (N=372) responded to a survey consisting of both intentional and unintentional wrongdoings that could occur by a nurse. Results of a paired t-test were as predicted. More wide ranging revelations found that respondents were more likely to discuss the unintentional wrongdoings with the wrongdoer in lieu of officially reporting to an immediate supervisor, or a member of upper management. Discussion, limitations, and suggestions for future research are provided.

Defined by a persistent fear of embarrassment or negative evaluation while engaged in social interaction or public performance, social anxiety disorder (SAD) is one of the most common psychiatric syndromes. Previous research has made a considerable effort to better understand and assess this mental disorder. However, little attention has been paid to social motor behavior of patients with SAD despite its crucial importance in daily social interactions. Previous research has shown that the coordination of arm, head or postural movements of interacting people can reflect their mental states or feelings such as social connectedness and social motives, suggesting that interpersonal movement coordination may be impaired in patients suffering from SAD. The current study was specifically aimed at determining whether SAD affects the dynamics of social motor coordination. We compared the unintentional and intentional rhythmic coordination of a SAD group (19 patients paired with control participants) with the rhythmic coordination of a control group (19 control pairs) in an interpersonal pendulum coordination task. The results demonstrated that unintentional social motor coordination was preserved with SAD while intentional coordination was impaired. More specifically, intentional coordination became impaired when patients with SAD had to lead the coordination as indicated by poorer (i.e., more variable) coordination. These differences between intentional and unintentional coordination as well as between follower and leader roles reveal an impaired coordination dynamics that is specific to SAD, and thus, opens promising research directions to better understand, assess and treat this mental disorder.

Relatively little is known about patterns of injury at the community level in Vietnam and their economic consequences. This study sought to estimate the costs of various unintentional injuries in Bavi District during one year; to describe how costs depended on gender, age, circumstances, and severity of injury; and to describe how the economic burden of unintentional injuries was distributed between households, government, and health insurance agency. A cohort study was undertaken, which involved four cross-sectional household surveys among sampled communities in the Bavi District during the year 2000, each asking about injuries in the preceding three months. The costing system in public healthcare in Vietnam was applied as well as information from the victims. The total cost of injuries over one year in Bavi District was estimated to be D3,412,539,000 (Vietnamese dong) (US$235,347), equivalent to the annual income of 1,800 people. In total, 90% of this economic burden fell on households, only 8% on government, and 2% on the health insurance agency. The cost of a severe injury to the corresponded to approximately seven months of earned income. Home and traffic injuries together accounted for more than 80% of the total cost, 45% and 38% respectively. The highest unit cost was related to traffic injuries, followed by home, "other", work-related, and school injuries in descending order. The results can be considered as an economic baseline that can be used in evaluations of future interventions aimed at preventing injuries.

Although many studies have focused on bus operators' occupational diseases, work-related injury and associated risk factor data are limited. The purpose of this longitudinal study was to investigate unintentional injury and exposures that may affect injury risk among metropolitan bus operators. Demographic, work-related, and injury data obtained from a metropolitan transit company for a 5-year period, enabled estimates of rates per 100 full time equivalents (FTEs) and adjusted Hazard Ratios (HRs), with 95% confidence intervals (CIs), using Generalized Estimating Equations and Cox proportional hazards models, respectively. The 2095 bus operators, included in this study, had an unintentional injury rate (95% CI) of 17.8 (16.1-19.7) per 100 FTEs. Multivariable analysis identified increased risks for operators who were female, compared to male (HR = 2.4; 2.0-2.8); worked less than 7 versus 7 to less than 12 hours per day (HR = 4.6; 3.8-5.5); and drove less than 7 versus 7 to less than 12 hours per day (HR = 3.2; 2.7-3.8). Suggestive increased risks were identified for operators working split versus straight shifts (HR = 1.2; 1.0-1.4) and for driving limited versus regular bus routes (HR = 1.36; 1.0-1.8). Results serve as a basis for further studies and inform the development of targeted intervention strategies to reduce bus operators' occupational injuries. Copyright © 2017 Elsevier Inc.

Hashemi, Esmatolsadat; Zangi, Mahdi; Sadeghi-Bazargani, Homayoun; Soares, Joaquim; Viitasara, Eija; Mohammadi, Reza

2018-01-01

Background: Our aim in this survey was to explore descriptive epidemiology of injuries in Tehran in 2012 and to report the recalled estimates of injury incidence rates. Methods: A population survey was conducted in Tehran during 2012, within which a total of 8626 participants were enrolled. The cluster sampling was used to draw samples in 100 clusters with a pre-specified cluster size of 25 households per cluster. Data were collected on demographic features, accident and injury characteristics based on the International Classification of Diseases (ICD10). Results: A total of 618 injuries per 3 months were reported, within which 597 cases (96.6%)were unintentional injuries. More than 82% of all injuries were those caused by exposure to inanimate mechanical forces, traffic accidents, falls and burns. Above 80% of the traffic injuries happened among men (P<0.001). About 43% of the unintentional injuries were mild injuries.After the age of 40, women, unlike men, had higher risks for being injured. The estimated annual incidence rate for all types of injuries was 284.8 per 1000 (95% CI: 275.4-294.4) and for unintentional injuries was 275.2 per 1000. Conclusion: Injuries are major health problems in Tehran with a highly reported incidence. The status is not substantially improved over the recent years which urges the need to be adequately and emergently addressed. As the incidence rate was estimated based on participant recalls, the real incidence rate may even be higher than those reported in the current study.

An increasing number of states are decriminalizing the use of medical marijuana, and the effect on the pediatric population has not been evaluated. To compare the proportion of marijuana ingestions by young children who sought care at a children's hospital in Colorado before and after modification of drug enforcement laws in October 2009 regarding medical marijuana possession. Retrospective cohort study from January 1, 2005, through December 31, 2011. Tertiary-care children's hospital emergency department in Colorado. A total of 1378 patients younger than 12 years evaluated for unintentional ingestions: 790 patients before September 30, 2009, and 588 patients after October 1, 2009. Marijuana ingestion. Marijuana exposure visits, marijuana source, symptoms, and patient disposition. The proportion of ingestion visits in patients younger than 12 years (age range, 8 months to 12 years)that were related to marijuana exposure increased after September 30, 2009, from 0 of 790 (0%; 95% CI, 0%-0.6%) to 14 of 588 (2.4%; 95% CI, 1.4%-4.0%) (P < .001). Nine patients had lethargy, 1 had ataxia, and 1 had respiratory insufficiency. Eight patients were admitted, 2 to the intensive care unit. Eight of the 14 cases involved medical marijuana, and 7 of these exposures were from food products. We found a new appearance of unintentional marijuana ingestions by young children after modification of drug enforcement laws for marijuana possession in Colorado. The consequences of unintentional marijuana exposure in children should be part of the ongoing debate on legalizing marijuana.

Trends and Patterns in Unintentional Injury Fatalities in Australian Agriculture.

Agriculture is recognized internationally as a hazardous industry. This article describes the trends and patterns of unintentional farm fatalities in Australia. Data from the National Coronial Information System were analyzed to assess all unintentional farm fatalities for the 2001-2015 period. A secondary comparison with earlier coronial system data from 1989-1992 was also completed to ascertain historical changes. There was no statistically significant change in the rate of work-related fatalities per 100,000 workers in the 2001-2015 period. However, there was a significant curvilinear reduction in all cases of fatality (work and non-work related) per 10,000 agricultural establishments, which decreased from 2001 to 2009-2011 and then increased to 2015. The longer-term data from 1989-2015 revealed a reduction of 30% in work-related cases per 100,000 workers and a reduction of 35% in all cases (work and non-work) per 10,000 agricultural establishments. For both work-related and all cases, there was a statistically significant reduction from 1989 to 2005 and then no change thereafter. The longer-term reduction in farm fatalities ceased in the mid-2000s, and the rate has remained stable since. Fatal injuries continue to impose a significant burden on Australian farming communities, with the rate remaining relatively static for the past ten years. New evidence-based interventions targeting priority areas are required to reduce the incidence of fatalities in Australia agriculture. Copyright© by the American Society of Agricultural Engineers.

Acute poisoning is one of the most common reasons for emergency department visits around the world. In Pakistan, the epidemiological data on poisoning is limited due to an under developed poison information surveillance system. We aim to describe the characteristics associated with intentional and unintentional poisoning in Pakistan presenting to emergency departments. The data was extracted from the Pakistan National Emergency Department Surveillance (Pak-NEDS) which was an active surveillance conducted between November 2010 and March 2011. All patients, regardless of age, who presented with poisoning to any of Pakistan's seven major tertiary care centers' emergency departments, were included. Information about patient demographics, type of poisoning agent, reason for poisoning and outcomes were collected using a standard questionnaire. Acute poisoning contributed to 1.2% (n = 233) of patients with intentional and unintentional injuries presenting to EDs of participating centers. Of these, 68% were male, 54% were aged 19 to 44 and 19% were children and adolescents (<18 years). Types of poisoning included chemical/gas (43.8%), drug/medicine (27%), alcohol (16.7%) and food/plant (6%). In half of all patients the poisoning was intentional. A total of 11.6% of the patients were admitted and 6.6% died. Poisoning causes more morbidity and mortality in young adults in Pakistan compared to other age groups, half of which is intentional. Improving mental health, regulatory control for hazardous chemicals and better access to care through poison information centers and emergency departments will potentially help control the problem.

What’s a Weed? Knowledge, Attitude and Behaviour of Park Visitors about Weeds

Ansong, Michael; Pickering, Catherine

2015-01-01

Weeds are a major threat to biodiversity globally degrading natural areas of high conservation value. But what are our attitudes about weeds and their management including weeds in national parks? Do we know what a weed is? Do we consider weeds a problem? Do we support their management? Are we unintentionally spreading weeds in parks? To answer these questions, we surveyed visitors entering a large popular national park near the city of Brisbane, Australia. Park visitors were knowledgeable about weeds; with >75% correctly defining weeds as ‘plants that grow where they are not wanted’. About 10% of the visitors, however, provided their own sophisticated definitions. This capacity to define weeds did not vary with people’s age, sex or level of education. We constructed a scale measuring visitors’ overall concern about weeds in parks using the responses to ten Likert scale statements. Over 85% of visitors were concerned about weeds with older visitors, hikers, and those who could correctly define weeds more concerned than their counterparts. The majority think visitors unintentionally introduce seeds into parks, with many (63%) having found seeds on their own clothing. However, over a third disposed of these seeds in ways that could facilitate weed spread. Therefore, although most visitors were knowledgeable and concerned about weeds, and support their control, there is a clear need for more effective communication regarding the risk of visitors unintentionally dispersing weed seeds in parks.

Benefits and concerns associated with biotechnology-derived foods: can additional research reduce children health risks?

PubMed

Cantani, A

2009-01-01

The development of techniques devised for the genetic manipulation of foods poses new risks for children with food allergy (FA). The introduction of foreign allergenic proteins from different foods into previously tolerated foods may trigger allergic reactions, often complicating with anaphylactic shock in a subset of allergic babies. Children with FA, even if subjected to preventative diets, always challenge the risk of developing allergic manifestations after unintentional intake of a non tolerated food in restaurant settings, with relatives or schoolmates, etc, where product labelling is necessarily lacking. The introduction of potentially allergenic proteins into foods generally considered safe for allergic children can be done deliberately, by either substantially altering the food ingredients, or by genetic manipulation which change the composition or transfer allergens, or unintentionally by qualitycontrol failures, due to contaminations in the production process, or to genetic mismanipulation. There is a controversy between multinationals often favored by governments and consumer association resistance, thus an equidistant analysis poses some unprecedented impediments. The importance of FA and the potential of transgenic plants to bring food allergens into the food supply should not be disregarded. The expression in soybeans of a Brazil nut protein resulted in a food allergen ex-pressed in widely used infant formulas, so paving the way to an often reported multinational debacle. Genetic engineering poses innovative ethical and social concerns, as well as serious challenges to the environment, human health, animal welfare, and the future of agriculture. In this paper will be emphasized practical concepts more crucial for pediatricians.

The influence of intention and outcome on evaluations of social interaction.

Wu, Xiaoying; Hua, Rui; Yang, Zhangxiang; Yin, Jun

2018-01-01

Reading and making sense of social interactions between individuals is an important part of our daily social lives. Given that actions tend to be interpreted in terms of intent within the observed outcome, we investigated how intent and outcome interactively influence evaluations of social interactions. Through visual animations, intent was operationalized as an agent's (i.e., actor's) act intentionally or unintentionally having an influence on another agent (i.e., affectee). In Experiment 1, the act was helpful and the consequences brought small or great benefits to the affectee. In Experiment 2, the act was harmful and brought small or great losses to the affectee. We found that for both helpful and harmful contexts, social interaction evaluations were influenced by an interaction between the intent and outcome of the act. Specifically, great help/harm (i.e., the great-benefits or great-losses condition) was rated as a stronger social interaction than small help/harm, and the difference was larger in the intentional condition than in the unintentional condition. Furthermore, regardless of the interaction valence, the effect of the intent was larger than the effect of the outcome when evaluating social interaction. This result suggests that observers consider the intent and outcome jointly when evaluating a given social interaction, and the intent has a privileged role in this process. These findings are consistent with the idea that the intent is often deemed to be the cause driving the effect of outcome, and they help us to understand how social interactions are constructed within the action understanding system.

The subjects performed a positional task against a constant baseline force and were instructed not to react to changes in the force. A HapticMaster robot produced a smooth force increase (a perturbation) leading to a hand movement, followed by a dwell time. No visible hand drift was observed during the dwell time. After the robot force dropped to its initial baseline value, the hand moved towards the initial position but stopped short of it. Small perturbations were applied at different time intervals along different directions during the dwell time. Arm apparent stiffness distribution in a horizontal plane was approximated with an ellipse. The apparent stiffness magnitude along the main axis of the ellipse showed a non-monotonic increase with dwell time while the apparent stiffness along the minor axis did not change significantly. We interpreted the early part of the changes in the apparent stiffness as due to peripheral muscle properties. The later part is interpreted as caused by a combination of two processes, a drift in the referent hand coordinate due to the hypothesized back-coupling between the referent and actual hand coordinates and an implicit instruction to keep the hand steady when no changes in robot-generated force took place. The data provide support for the idea of back-coupling between the referent and actual body configurations, which may be an important contributor to stability of motor actions. PMID:26169103

Managing tissue bank access to the OR for tissue recovery.

PubMed

Trim, Robert S

2011-08-01

Hospitals often have tissue recovery service agreements with regional tissue banks to facilitate the donation process. The agreements that outline the tissue bank-hospital relationship frequently allow tissue bank personnel to perform tissue recovery procedures in the referring hospital's OR and may or may not specify any preparatory orientation or any written protocols for tissue bank staff members to follow. This creates the potential for unintentional breaches of protocol that can affect operation of equipment or result in contamination that may put surgical patients and staff members at risk. The OR manager is responsible for establishing appropriate orientation plans for tissue bank employees to ensure they understand and adhere to the hospital's protocols. Copyright © 2011 AORN, Inc.

Polarization imaging of imperfect m-plane GaN surfaces

NASA Astrophysics Data System (ADS)

Sakai, Yuji; Kawayama, Iwao; Nakanishi, Hidetoshi; Tonouchi, Masayoshi

2017-04-01

Surface polar states in m-plane GaN wafers were studied using a laser terahertz (THz) emission microscope (LTEM). Femtosecond laser illumination excites THz waves from the surface due to photocarrier acceleration by local spontaneous polarization and/or the surface built-in electric field. The m-plane, in general, has a large number of unfavorable defects and unintentional polarization inversion created during the regrowth process. The LTEM images can visualize surface domains with different polarizations, some of which are hard to visualize with photoluminescence mapping, i.e., non-radiative defect areas. The present study demonstrates that the LTEM provides rich information about the surface polar states of GaN, which is crucial to improve the performance of GaN-based optoelectronic and power devices.

A Novel Distributed Privacy Paradigm for Visual Sensor Networks Based on Sharing Dynamical Systems

NASA Astrophysics Data System (ADS)

Luh, William; Kundur, Deepa; Zourntos, Takis

2006-12-01

Visual sensor networks (VSNs) provide surveillance images/video which must be protected from eavesdropping and tampering en route to the base station. In the spirit of sensor networks, we propose a novel paradigm for securing privacy and confidentiality in a distributed manner. Our paradigm is based on the control of dynamical systems, which we show is well suited for VSNs due to its low complexity in terms of processing and communication, while achieving robustness to both unintentional noise and intentional attacks as long as a small subset of nodes are affected. We also present a low complexity algorithm called TANGRAM to demonstrate the feasibility of applying our novel paradigm to VSNs. We present and discuss simulation results of TANGRAM.

Effective interventions for unintentional injuries: a systematic review and mortality impact assessment among the poorest billion.

PubMed

Vecino-Ortiz, Andres I; Jafri, Aisha; Hyder, Adnan A

2018-05-01

Between 1990 and 2015, the global injury mortality declined, but in countries where the poorest billion live, injuries are becoming an increasingly prevalent cause of death. The vulnerability of this population requires immediate attention from policy makers to implement effective interventions that lessen the burden of injuries in these countries. Our aim was two-fold; first, to review all the evidence on effective interventions for the five main types of unintentional injury; and second, to estimate the potential number of lives saved by effective injury interventions among the poorest billion. For our systematic review we used references in the Disability Control Priorities third edition, and searched PubMed and the Cochrane database for papers published until Sept 10, 2016, using a comprehensive search strategy to find interventions for the five major causes of unintentional injuries: road traffic crashes, falls, drowning, burns, and poisoning. Studies were included if they presented evidence with significant effects sizes for any outcome; no inclusions or exclusions made on the basis of where the study was carried out (ie, low-income, middle-income, or high-income country). Then we used data from the Global Burden of Disease 2015 study and a Monte Carlo simulation technique to estimate the potential annual attributable number of lives saved among the poorest billion by these evidence-based injury interventions. We estimated results for 84 countries where the poorest billion live. From the 513 papers identified, 47 were eligible for inclusion. We identified 11 interventions that had an effect on injury mortality. For road traffic deaths, the most successful interventions in preventing deaths are speed enforcement (>80 000 lives saved per year) and drink-driving enforcement (>60 000 lives saved per year). Interventions potentially most effective in preventing deaths from drowning are formal swimming lessons for children younger than 14 years (>25 000 lives saved per year) and the use of crèches to supervise younger children (younger than 5 years; >10 000 lives saved per year). We did not find sufficient evidence on interventions for other causes of unintentional injuries (poisoning, burns, and falls) to run similar simulations. Based on the little available evidence, key interventions have been identified to prevent lives lost from unintentional injuries among the poorest billion. This Article provides guidance to national authorities on evidence-based priority interventions that can reduce the burden of injuries among the most vulnerable members of the population. We also identify an important gap in knowledge on the effectiveness and the mortality impacts of injury interventions.

Transvenous pacemaker electrodes placed unintentionally in the left ventricle: three cases.

PubMed Central

Winner, S. J.; Boon, N. A.

1989-01-01

Three patients are described in whom pacemaker electrodes were unintentionally placed within the left ventricle, followed by considerable delay before the error was recognized. In two cases temporary pacemaker wires were inserted into the subclavian artery and passed along a retrograde course. One patient required urgent surgery for acute arterial obstruction on removal of the wire. In the third case, a permanent wire was inserted correctly into a vein but traversed the atrial septum, probably via a patent foramen ovale, to enter the left ventricle. Twelve lead electrocardiograms in all three patients showed paced complexes with right bundle branch block configuration. This appearance should raise suspicion that the pacemaker electrode might be in the left ventricle, in which case its position should be defined by chest radiographs (including a lateral view) and echocardiography.

Toddlers’ Unintentional Injuries: The Role of Maternal-Reported Paternal and Maternal Supervision*

PubMed Central

Kuhn, Jennifer

2013-01-01

Research indicates that mothers’ supervision protects children from injuries. However, little research has examined the role of fathers’ supervision in children’s injuries. Objectives This study compared the role of maternal and paternal supervision in children’s injury risk and severity using maternal reports. Methods Mothers (n = 170) of toddlers were interviewed for 6 months about their children’s unintentional injuries. Results Children were more likely to engage in high activity levels and were at higher risk for injury when being cared for by their fathers. Although higher supervision predicted lower injury risk for both mothers and fathers, fathers’ close supervision (as reported by mothers) was a stronger predictor of injury risk than mothers’ supervision. Conclusion Children’s higher levels of activities may have accounted for their higher risk of injury when in their fathers’ care. These findings indicate the need to include fathers in injury prevention efforts. PMID:23143608

Effectiveness of measures to prevent unintentional deaths of infants and children from suffocation and strangulation.

PubMed Central

Kraus, J F

1985-01-01

Unintentional deaths from suffocation and strangulation account for about 20 percent of all nontransport-related infant and child fatalities in the United States. In the late 1950s, some preventive countermeasures were introduced to reduce the number of deaths resulting from refrigerator or freezer entrapment. A few years later, countermeasures were introduced to prevent deaths resulting from suffocation by plastic bags, inhumation, and mechanical strangulation from wedging in infant cribs. For three of these major causes of suffocation and strangulation deaths among infants and children (refrigerator or freezer entrapment, suffocation by plastic bag, and inhumation at construction sites), there appears to have been a significant decline in incidence; however, there is no evidence of a significant reduction in deaths from mechanical strangulation in cribs. The impact of current countermeasures is discussed, and some suggestions for new or modified approaches are made. PMID:3920722

QuickStats: Age-Adjusted Death Rates* for Females Aged 15-44 Years, by the Five Leading Causes of Death(†) - United States, 1999 and 2014.

PubMed

2016-07-01

The age-adjusted death rate for females aged 15-44 years was 5% lower in 2014 (82.1 per 100,000 population) than in 1999 (86.5). Among the five leading causes of death, the age-adjusted rates of three were lower in 2014 than in 1999: cancer (from 19.6 to 15.3, a 22% decline), heart disease (8.9 to 8.2, an 8% decline), and homicide (4.2 to 2.8, a 33% decline). The age-adjusted death rates for two of the five causes were higher in 2014 than in 1999: unintentional injuries (from 17.0 to 20.1, an 18% increase) and suicide (4.8 to 6.5, a 35% increase). Unintentional injuries replaced cancer as the leading cause of death in this demographic group.

Eyes, bones and teeth in the 16th century Statute law of Rijeka.

PubMed

Milovic, Dorde; Milovic Karic, Grozdana

2008-01-01

The 16th century statute law or the town of Rijeka treats the eye in two ways. First, it stipulates a severe punishment for deliberate "eye-plucking". Second, for those who commit this crime, it specifies "eye-plucking" as a corporeal punishment (following the eye-for-an-eye principle).The 1530 Statute of Rijeka also pays considerable attention to the bones. Bone breaking by means of intentional or unintentional blow was fined 25 libras (pounds) for the following bones: thighbone, forearm and hand bones, lower leg bone, and foot bone. A fine of 10 libras applied for all other intentional or unintentional bone breaking by a blow. Legal protection of teeth involved a fine of five libras for each of the teeth blown out, and half the fine for a broken tooth. Both fines applied whether the offence was done on purpose or not.

Cyber Friendly Fire: Research Challenges for Security Informatics

DOE Office of Scientific and Technical Information (OSTI.GOV)

Greitzer, Frank L.; Carroll, Thomas E.; Roberts, Adam D.

This paper addresses cognitive implications and research needs surrounding the problem of cyber friendly fire (FF). We define cyber FF as intentional offensive or defensive cyber/electronic actions intended to protect cyber systems against enemy forces or to attack enemy cyber systems, which unintention-ally harms the mission effectiveness of friendly or neutral forces. Just as with combat friendly fire, maintaining situation awareness (SA) is paramount to avoiding cyber FF incidents. Cyber SA concerns knowledge of a system’s topology (connectedness and relationships of the nodes in a system), and critical knowledge elements such as the characteristics and vulnerabilities of the components thatmore » comprise the system and its nodes, the nature of the activities or work performed, and the available defensive and offensive countermeasures that may be applied to thwart network attacks. Mitigation strategies to combat cyber FF— including both training concepts and suggestions for decision aids and visualization approaches—are discussed.« less

Maintaining Perioperative Normothermia: Sustaining an Evidence-Based Practice Improvement Project.

PubMed

Levin, Rona F; Wright, Fay; Pecoraro, Kathleen; Kopec, Wendy

2016-02-01

Unintentional perioperative hypothermia has been shown to cause serious patient complications and, thus, to increase health care costs. In 2009, an evidence-based practice improvement project produced a significant decrease in unintentional perioperative hypothermia in colorectal surgical patients through monitoring of OR ambient room temperature. Project leaders engaged all interdisciplinary stakeholders in the original project, which facilitated the sustainability of the intervention method. An important aspect of sustainability is ongoing monitoring and evaluation of a new intervention method. Therefore, continued evaluation of outcomes of the protocol developed in 2009 was scheduled at specific time points after the initial small test of change with colorectal patients. This article focuses on how attention to sustainability factors during implementation of an improvement project led to the sustainability of a protocol for monitoring OR ambient room temperature with all types of surgical patients five years after the initial project.

A fatal outcome after unintentional overdosing of rivastigmine patches.

PubMed

Lövborg, Henrik; Jönsson, Anna K; Hägg, Staffan

2012-02-01

Rivastigmine is an acetylcholine esterase inhibitor used in the treatment of dementia. Patches with rivastigmine for transdermal delivery have been used to increase compliance and to reduce side effects. We describe an 87-year old male with dementia treated with multiple rivastigmine patches (Exelon 9,5 mg/24 h) who developed nausea, vomiting and renal failure with disturbed electrolytes resulting in death. The symptoms occurred after six rivastigmine patches had concomitantly been erroneously applied by health care personnel on two consecutive days. The terminal cause of death was considered to be uremia from an acute tubular necrosis that was assessed as a result of dehydration through vomiting. The rivastigmine intoxication was assessed as having caused or contributed to the dehydrated condition. The medication error occurred at least partly due to ambiguous labeling. The clinical signs were not initially recognized as adverse effects of rivastigmine. The presented case is a description of a rivastigmine overdose due to a medication error involving patches. This case indicates the importance of clear and unambiguous instructions to avoid administration errors with patches and to be vigilant to adverse drug reactions for early detection and correction of drug administration errors. In particular, instructions clearly indicating that only one patch should be applied at a time are important.

Alternative Packaging for Back-Illuminated Imagers

NASA Technical Reports Server (NTRS)

Pain, Bedabrata

2009-01-01

An alternative scheme has been conceived for packaging of silicon-based back-illuminated, back-side-thinned complementary metal oxide/semiconductor (CMOS) and charge-coupled-device image-detector integrated circuits, including an associated fabrication process. This scheme and process are complementary to those described in "Making a Back-Illuminated Imager With Back-Side Connections" (NPO-42839), NASA Tech Briefs, Vol. 32, No. 7 (July 2008), page 38. To avoid misunderstanding, it should be noted that in the terminology of imaging integrated circuits, "front side" or "back side" does not necessarily refer to the side that, during operation, faces toward or away from a source of light or other object to be imaged. Instead, "front side" signifies that side of a semiconductor substrate upon which the pixel pattern and the associated semiconductor devices and metal conductor lines are initially formed during fabrication, and "back side" signifies the opposite side. If the imager is of the type called "back-illuminated," then the back side is the one that faces an object to be imaged. Initially, a back-illuminated, back-side-thinned image-detector is fabricated with its back side bonded to a silicon handle wafer. At a subsequent stage of fabrication, the front side is bonded to a glass wafer (for mechanical support) and the silicon handle wafer is etched away to expose the back side. The frontside integrated circuitry includes metal input/output contact pads, which are rendered inaccessible by the bonding of the front side to the glass wafer. Hence, one of the main problems is to make the input/output contact pads accessible from the back side, which is ultimately to be the side accessible to the external world. The present combination of an alternative packaging scheme and associated fabrication process constitute a solution of the problem.

Using the public health model to address unintentional injuries and TBI: A perspective from the Centers for Disease Control and Prevention (CDC).

PubMed

Baldwin, Grant; Breiding, Matt; Sleet, David

2016-06-30

Traumatic brain injury (TBI) can have long term effects on mental and physical health, and can disrupt vocational, educational, and social functioning. TBIs can range from mild to severe and their effects can last many years after the initial injury. CDC seeks to reduce the burden of TBI from unintentional injuries through a focus on primary prevention, improved recognition and management, and intervening to improve health outcomes after TBI. CDC uses a 4-stage public health model to guide TBI prevention, moving from 1) surveillance of TBI, 2) identification of risk and protective factors for TBI, 3) development and testing of evidence-based interventions, to 4) bringing effective intervention to scale through widespread adoption. CDC's unintentional injury prevention activities focus on the prevention of sports-related concussions, motor vehicle crashes, and older adult falls. For concussion prevention, CDC developed Heads Up - an awareness initiative focusing on ways to prevent a concussion in sports, and identifying how to recognize and manage potential concussions. In motor vehicle injury prevention, CDC has developed a tool (MV PICCS) to calculate the expected number of injuries prevented and lives saved using various evidence-based motor vehicle crash prevention strategies. To help prevent TBI related to older adult falls, CDC has developed STEADI, an initiative to help primary care providers identify their patients' falls risk and provide effective interventions. In the future, CDC is focused on advancing our understanding of the public health burden of TBI through improved surveillance in order to produce more comprehensive estimates of the public health burden of TBI.

Task-specific stability in muscle activation space during unintentional movements.

PubMed

Falaki, Ali; Towhidkhah, Farzad; Zhou, Tao; Latash, Mark L

2014-11-01

We used robot-generated perturbations applied during position-holding tasks to explore stability of induced unintentional movements in a multidimensional space of muscle activations. Healthy subjects held the handle of a robot against a constant bias force and were instructed not to interfere with hand movements produced by changes in the external force. Transient force changes were applied leading to handle displacement away from the initial position and then back toward the initial position. Intertrial variance in the space of muscle modes (eigenvectors in the muscle activations space) was quantified within two subspaces, corresponding to unchanged handle coordinate and to changes in the handle coordinate. Most variance was confined to the former subspace in each of the three phases of movement, the initial steady state, the intermediate position, and the final steady state. The same result was found when the changes in muscle activation were analyzed between the initial and final steady states. Changes in the dwell time between the perturbation force application and removal led to different final hand locations undershooting the initial position. The magnitude of the undershot scaled with the dwell time, while the structure of variance in the muscle activation space did not depend on the dwell time. We conclude that stability of the hand coordinate is ensured during both intentional and unintentional actions via similar mechanisms. Relative equifinality in the external space after transient perturbations may be associated with varying states in the redundant space of muscle activations. The results fit a hierarchical scheme for the control of voluntary movements with referent configurations and redundant mapping between the levels of the hierarchy.

Unintentional and undetermined firearm related deaths: a preventable death analysis for three safety devices.

2003-12-01

To determine the proportion of unintentional and undetermined firearm related deaths preventable by three safety devices: personalization devices, loaded chamber indicators (LCIs), and magazine safeties. A personalized gun will operate only for an authorized user, a LCI indicates when the gun contains ammunition, and a magazine safety prevents the gun from firing when the ammunition magazine is removed. Information about all unintentional and undetermined firearm deaths from 1991-98 was obtained from the Office of the Chief Medical Examiner for Maryland, and from the Wisconsin Firearm Injury Reporting System for Milwaukee. Data regarding the victim, shooter, weapon, and circumstances were abstracted. Coding rules to classify each death as preventable, possibly preventable, or not preventable by each of the three safety devices were also applied. There were a total of 117 firearm related deaths in our sample, 95 (81%) involving handguns. Forty three deaths (37%) were classified as preventable by a personalized gun, 23 (20%) by a LCI, and five (4%) by a magazine safety. Overall, 52 deaths (44%) were preventable by at least one safety device. Deaths involving children 0-17 (relative risk (RR) 3.3, 95% confidence interval (CI) 2.1 to 5.1) and handguns (RR 8.1, 95% CI 1.2 to 53.5) were more likely to be preventable. Projecting the findings to the entire United States, an estimated 442 deaths might have been prevented in 2000 had all guns been equipped with these safety devices. Incorporating safety devices into firearms is an important injury intervention, with the potential to save hundreds of lives each year.

A comparison of two surveillance systems for deaths related to violent injury

PubMed Central

Comstock, R; Mallonee, S; Jordan, F

2005-01-01

Objective: To compare violent injury death reporting by the statewide Medical Examiner and Vital Statistics Office surveillance systems in Oklahoma. Methods: Using a standard study definition for violent injury death, the sensitivity and predictive value positive (PVP) of the Medical Examiner and Vital Statistics violent injury death reporting systems in Oklahoma in 2001 were evaluated. Results: Altogether 776 violent injury deaths were identified (violent injury death rate: 22.4 per 100 000 population) including 519 (66.9%) suicides, 248 (32.0%) homicides, and nine (1.2%) unintentional firearm deaths. The Medical Examiner system over-reported homicides and the Vital Statistics system under-reported homicides and suicides and over-reported unintentional firearm injury deaths. When compared with the standard, the Medical Examiner and Vital Statistics systems had sensitivities of 99.2% and 90.7% (respectively) and PVPs of 95.0% and 99.1% for homicide, sensitivities of 99.2% and 93.1% and PVPs of 100% and 99.0% for suicide, and sensitivities of 100% and 100% and PVPs of 100% and 31.0% for unintentional firearm deaths. Conclusions: Both the Vital Statistics and Medical Examiner systems contain valuable data and when combined can work synergistically to provide violent injury death information while also serving as quality control checks for each other. Preventable errors within both systems can be reduced by increasing training, addressing sources of human error, and expanding computer quality assurance programming. A standardized nationwide Medical Examiners' coding system and a national violent death reporting system that merges multiple public health and criminal justice datasets would enhance violent injury surveillance and prevention efforts.

2014-01-01

Hypocalcemia and unintentional parathyroidectomy would be associated as cause of post-thyroidectomy hypocalcemia. We analysed the cases treated with total thyroidectomy by two experienced endocrine surgeons from January 2010 to December 2011 at the Unit of General Surgery and Organ Transplantation of the University Hospital of Parma. These cases were divided in two groups: "Group A" included patients for whom a histological report was made that was negative for a parathyroid avulsion, and "Group B" included patients for whom an inadvertent avulsion of the intracapsular parathyroid glands had occurred. In total, 538 patients were treated with a total thyroidectomy from January 2010 to December 2011. In 26 cases, the histological report highlighted the presence of an intracapsular parathyroid gland. The values of pre-operative calcaemia in group A and group B were 9.204 ± 0.2703 mg/dl versus 9.283 ± 0.401 mg/dl, respectively (p=0.32). The values of post-operative calcaemia were 8.039 ± 0.596 mg/dl for group A versus 7.569 ± 0.618 mg/dl for group B (p=0.0002) In Group A, 91/512 patients were treated with the minimally invasive video-assisted thyroidectomy (MIVAT) technique (17,7%), while 1/26 patients in group B was treated with a MIVAT (3,8%). Unintentional parathyroidectomies can occur with experienced surgeons, but this complication is not related to a substantial difference in the incidence of hypocalcemia. MIVAT can helps the endocrine surgeon in the detection of the parathyroids glands, but when the parathyroid is intracapsular, is difficult to preserve it, during surgical dissection.

Non-invasive ventilation: evaluation of CO2 washout by intentional leaking in three recent oronasal masks. A pilot study.

Many types of interfaces with intentional leaks exist for Non Invasive Ventilation. The purpose of intentional leaks is to remove CO2 from the interface, however the calibration does not allow a sufficiently large flow and rebreathing of CO2 can occur. The aim of this study was to compare the CO2 rinsing capacities of three new generation oronasal masks with intentional leaks (A: Quattro®, [Resmed]; B: Amara® [Respironics]; C: Forma® [Fisher&Paykel]) in healthy subjects. Seventeen healthy volunteers were included in this prospective cross-sectional, randomized, double-blinded trial. Each subject underwent ventilation with a home ventilator (IPAP: 14 cmH2O; EPAP: 4 cmH2O) with each mask consecutively. Transcutaneous capnography (PtcCO2) recordings were carried out throughout the trial and ventilator data (tidal volume, respiratory rate, minute ventilation and unintentional leaks) were also analyzed. Mask comfort was assessed using a visual analog scale (0 to 10). The results showed no differences in PtcCO2 between masks (P=0.82). There were no significant differences in respiratory parameters (tidal volume, P=0.79; respiratory rate, P=0.65; minute ventilation, P=0.12) between masks. The rate of unintentional leaks were significantly lower for Mask A (P=0.016). Subjects rated Mask A and Mask C as more comfortable than Mask B (P=0.041). There was no effect of mask on PtcCO2 in healthy subjects. The mask with the highest comfort rating had not the lowest rate of unintentional leaks.

To characterize nonfatal, unintentional, fall-related injuries associated with walkers and canes in older adults. Surveillance data of injuries treated in hospital emergency departments (EDs), January 1, 2001, to December 31, 2006. The National Electronic Injury Surveillance System All Injury Program, which collects data from a nationally representative stratified probability sample of 66 U.S. hospital EDs. People aged 65 and older treated in EDs for 3,932 nonfatal unintentional fall injuries and whose records indicated that a cane or a walker was involved in the fall. Sex, age, whether the fall involved a cane or walker, primary diagnosis, part of the body injured, disposition, and location and circumstances of the fall. An estimated 47,312 older adult fall injuries associated with walking aids were treated annually in U.S. EDs: 87.3% with walkers, 12.3% with canes, and 0.4% with both. Walkers were associated with seven times as many injuries as canes. Women's injury rates exceeded those for men (rate ratios=2.6 for walkers, 1.4 for canes.) The most prevalent injuries were fractures and contusions or abrasions. Approximately one-third of subjects were hospitalized for their injuries. Injuries and hospital admissions for falls associated with walking aids were frequent in this highly vulnerable population. The results suggest that more research is needed to improve the design of walking aids. More information also is needed about the circumstances preceding falls, both to better understand the contributing fall risk factors and to develop specific and effective fall prevention strategies.

Fatal occupational injuries in a southern state.

1997-06-15

Fatal occupational injuries were studied using data from medical examiners' reports in North Carolina for the years 1977-1991. Cases were defined as deaths due to accidents or homicide at the workplace, and populations at risk were estimated from the 1980 and 1990 US Censuses. Mortality rate ratios and proportionate mortality ratios were used as measures of association, and the population attributable risk percentage was used as an indicator of the burden of injury. Standard weights for direct age-adjustment of rates were obtained from the total state workforce. There were 2,524 eligible deaths-83 percent from unintentional traumatic injuries, 14 percent from homicide, and the remainder from other causes. This report focuses on unintentional trauma deaths, which were strongly associated with the wood production, fishing, and transportation industries. Elderly, African-American, and self-employed workers had higher fatality rates than members of other groups. Among male workers, motor vehicle crashes were the principal cause of death on the job, followed by falling objects, machinery, and falls. The industries contributing the largest proportions of these deaths were construction, trucking, agriculture, and logging (population attributable risk percentages were 16.8%, 8.8%, 7.9%, and 6.9%, respectively). The fatality patterns of female workers were different: Numbers of deaths from homicide and unintentional trauma were equal, and 27% of the latter deaths occurred in one catastrophic fire. Decentralized and rural industries were the most hazardous, but many deaths were outside the current jurisdiction of occupational safety and health agencies. These patterns suggest that greater scrutiny of such industries, through both research and intervention, is warranted.

In the United States, fatal drug overdoses have tripled since 1991. This escalation in deaths is believed to be driven primarily by prescription opioid medications. This investigation compared trends and patterns in sales of opioids, opioid drug overdoses treated in emergency departments (EDs), and unintentional overdose deaths in North Carolina (NC). Our ecological study compared rates of opioid sales, opioid related ED overdoses, and unintentional drug overdose deaths in NC. Annual sales data, provided by the Drug Enforcement Administration, for select opioids were converted into morphine equivalents and aggregated by zip code. These opioid drug sales rates were trended from 1997 to 2010. In addition, opioid sales were correlated and compared to opioid related ED visits, which came from a Centers for Disease Control and Prevention syndromic surveillance system, and unintentional overdose deaths, which came from NC Vital Statistics, from 2008 to 2010. Finally, spatial cluster analysis was performed and rates were mapped by zip code in 2010. Opioid sales increased substantially from 1997 to 2010. From 2008 to 2010, the quarterly rates of opioid drug overdoses treated in EDs and opioid sales correlated (r=0.68, p=0.02). Specific regions of the state, particularly in the southern and western corners, had both high rates of prescription opioid sales and overdoses. Temporal trends in sales of prescription opioids correlate with trends in opioid related ED visits. The spatial correlation of opioid sales with ED visit rates shows that opioid sales data may be a timely way to identify high-risk communities in the absence of timely ED data.

Intentional and unintentional poisoning in Pakistan: a pilot study using the Emergency Departments surveillance project

PubMed Central

2015-01-01

Background Acute poisoning is one of the most common reasons for emergency department visits around the world. In Pakistan, the epidemiological data on poisoning is limited due to an under developed poison information surveillance system. We aim to describe the characteristics associated with intentional and unintentional poisoning in Pakistan presenting to emergency departments. Methods The data was extracted from the Pakistan National Emergency Department Surveillance (Pak-NEDS) which was an active surveillance conducted between November 2010 and March 2011. All patients, regardless of age, who presented with poisoning to any of Pakistan's seven major tertiary care centers' emergency departments, were included. Information about patient demographics, type of poisoning agent, reason for poisoning and outcomes were collected using a standard questionnaire. Results Acute poisoning contributed to 1.2% (n = 233) of patients with intentional and unintentional injuries presenting to EDs of participating centers. Of these, 68% were male, 54% were aged 19 to 44 and 19% were children and adolescents (<18 years). Types of poisoning included chemical/gas (43.8%), drug/medicine (27%), alcohol (16.7%) and food/plant (6%). In half of all patients the poisoning was intentional. A total of 11.6% of the patients were admitted and 6.6% died. Conclusion Poisoning causes more morbidity and mortality in young adults in Pakistan compared to other age groups, half of which is intentional. Improving mental health, regulatory control for hazardous chemicals and better access to care through poison information centers and emergency departments will potentially help control the problem.

Violence and injuries are under-reported in developing countries, especially during natural disasters such as floods. Compounding this, affected areas are isolated from the rest of the country. During 2007 Bangladesh experienced two consecutive floods which affected almost one-third of the country. The objective of this study was to examine unintentional injuries to children in rural Bangladesh and parental violence against them during floods, and also to explore the association of socioeconomic characteristics. A cross-sectional rural household survey was conducted in the worst flood-affected areas. A group of 638 randomly selected married women of reproductive age with at least one child at home were interviewed face-to-face using pre-tested structured questionnaires. The chi2 test and logistic regression were used for data analysis. The majority of families (90%) were affected by the flood and were struggling to find food and shelter, resulting in the parents becoming violent towards their children and other family members in the home. Cuts (38%), falls (22%) and near drowning (21%) comprised the majority of unintentional injuries affecting children during the floods. A large number of children were abused by their parents during the floods (70% by mothers and 40% by fathers). The incidence of child injuries and parental violence against children was higher among families living in poor socio-economic conditions, whose parents were of low occupational status and had micro-credit loans during the floods. Floods can have significant effects on childhood injury and parental violence against children. The improvement of socio-economic conditions would assist in preventing child injuries and parental violence.

To summarize, polycrystalline ZnO thin films were grown by reactive sputtering. Nitrogen was introduced into the films by reactive sputtering in an NO 2 plasma or by N + implantation. All ZnO films grown show n-type conductivity. In unintentionally doped ZnO films, the n-type conductivities are attributed to Zn i, a native shallow donor. In NO 2-grown ZnO films, the n-type conductivity is attributed to (N 2) O, a shallow double donor. In NO 2-grown ZnO films, 0.3 atomic % nitrogen was found to exist in the form of N 2O and N 2. Upon annealing, N 2O decomposes intomore » N 2 and O 2. In furnace-annealed samples N 2 redistributes diffusively and forms gaseous N 2 bubbles in the films. Unintentionally doped ZnO films were grown at different oxygen partial pressures. Zni was found to form even at oxygen-rich condition and led to n-type conductivity. N + implantation into unintentionally doped ZnO film deteriorates the crystallinity and optical properties and leads to higher electron concentration. The free electrons in the implanted films are attributed to the defects introduced by implantation and formation of (N 2) O and Zni. Although today there is still no reliable means to produce good quality, stable p-type ZnO material, ZnO remains an attractive material with potential for high performance short wavelength optoelectronic devices. One may argue that gallium nitride was in a similar situation a decade ago. Although we did not obtain any p-type conductivity, we hope our research will provide a valuable reference to the literature.« less

Zolpidem (Ambien): a pediatric case series.

Kurta, D L; Myers, L B; Krenzelok, E P

1997-01-01

In 1993, the nonbenzodiazepine sedative-hypnotic zolpidem tartrate (Ambien) was approved for use in the US. Zolpidem has an imidazopyridine structure and possesses a rapid onset of action and a short half-life. The toxic threshold and profile have not been well established in the pediatric population. All pediatric zolpidem exposures reported to a regional poison information center over 24 months were reviewed retrospectively from the American Association of Poison Control Centers Toxic Exposure Surveillance System data collection forms. Twelve pediatric zolpidem exposures were reported. Seven were unintentional (ages 20 mon-5 y) and five were intentional misuse/suicide (ages 12-16 y). The regional poison information center was contacted within 1 h in ten cases with onset of symptoms within 10 to 60 min (mean 31.6 min). One child had no effect with 2.5 mg. As little as 5 mg caused symptoms with minor outcome in six unintentional ingestions (5-30 mg). Minor to moderate symptoms were reported 1-4 h after intentional ingestions (12.5-150 mg). The duration of symptoms in the unintentional cases ranged from less than 60 min up to 4 h (mean 2.4 h) and 6-10 h (mean 7.5 h) in the intentional exposures. Treatment consisted of observation (4), syrup of ipecac (1), lavage and activated charcoal (1), activated charcoal alone (5), and unknown (1). Due to the very rapid onset of central nervous system symptoms in children, emesis is not a treatment option. Supportive care, activated charcoal in large ingestions, and observation until symptoms resolve may be sufficient in most pediatric cases.

Change in child mortality patterns after injuries in Sweden: a nationwide 14-year study.

PubMed

Bäckström, D; Steinvall, I; Sjöberg, F

2017-06-01

Sweden has one of the world's lowest child injury mortality rates, but injuries are still the leading cause of death among children. Child injury mortality in the country has been declining, but this decline seems to decrease recently. Our objective was therefore to further examine changes in the mortality of children's death from injury over time and to assess the contribution of various effects on mortality. The underlying hypothesis for this investigation is that the incidence of lethal injuries in children, still is decreasing and that this may be sex specific. We studied all deaths from injury in Sweden under-18-year-olds during the 14 years 1999-2012. We identified those aged under 18 whose underlying cause of death was recorded as International Classification of Diseases, 10th Revision (ICD-10) diagnosis from V01 to X39 in the Swedish cause of death, where all dead citizens are registered. From the 1 January 1999 to 31 December 2012, 1213 children under the age of 18 died of injuries in Sweden. The incidence declined during this period (r = -0.606, p = 0.02) to 3.3 deaths/100,000 children-years (95 % CI 2.6-4.2). Death from unintentional injury was more common than that after intentional injury (p < 0.0001). There was a reduction in the incidence of unintentional injuries during the study period (r = -0.757, p = 0.03). The most common causes of death were injury to the brain (n = 337, 41 %), followed by drowning (n = 109, 13 %). The number of deaths after intentional injury increased (r = 0.585, p = 0.03) and at the end of the period was 1.5 deaths/100,000 children-years. The most common causes of death after intentional injuries were asphyxia (n = 177, 45 %), followed by injury to the brain (n = 76, 19 %). Mortality patterns in injured children in Sweden have changed from being dominated by unintentional injuries to a more equal distribution between unintentional and intentional injuries as well as between sexes and the overall rate has declined further. These findings are important as they might contribute to the preventive work that is being done to further reduce mortality in injured children.

Medication reconciliation reduces potential medication discrepancies and adverse drug events. The role of pharmacy technicians in obtaining best possible medication histories (BPMHs) and performing reconciliation at the admission and transfer interfaces of care for pediatric patients has not been described. To compare the completeness and accuracy of BPMHs and reconciliation conducted by a pharmacy technician (pilot study) and by nurses and/or pharmacists (baseline). The severity of identified unintentional discrepancies was rated to determine their clinical importance. This prospective cohort comparison study involved patients up to 18 years of age admitted to and/or transferred between the Cardiology ward and the Cardiac Critical Care Unit of a pediatric tertiary care teaching hospital. A pharmacy resident conducted two 3-week audits: the first to assess the completeness and accuracy of BPMHs and reconciliation performed by nurses and/or pharmacists and the second to assess the completeness and accuracy of BPMHs and reconciliation performed by a pharmacy technician. The total number of patients was 38 in the baseline phase and 46 in the pilot period. There were no statistically significant differences between the baseline and pilot audits in terms of completion of BPMH (82% [28/34] versus 78% [21/27], p = 0.75) or completion of reconciliation (70% [23/33] versus 75% [15/20], p = 0.76) within 24 h of admission. Completeness of transfer reconciliation was significantly higher during the pilot study than at baseline (91% [31/34] versus 61% [11/18], p = 0.022). No significant differences between the baseline and pilot audits were found in the proportions of patients with at least one BPMH discrepancy (38% [13/34] versus 22% [6/27], p = 0.27), at least one unintentional discrepancy upon admission (21% [7/33] versus 10% [2/20], p = 0.46), or at least one unintentional discrepancy at the transfer interface (6% [1/18] versus 3% [1/34], p = 0.58). None of the 16 unintentional discrepancies were rated as causing severe patient discomfort or clinical deterioration. A trained pharmacy technician can perform admission and transfer medication reconciliation for pediatric patients with completeness and accuracy comparable to those of nurses and pharmacists. Future studies should explore the sustainability and cost-effectiveness of this practice model.

Cutting thin glass by femtosecond laser ablation

NASA Astrophysics Data System (ADS)

Shin, Hyesung; Kim, Dongsik

2018-06-01

The femtosecond laser ablation process for cutting thin aluminoborosilicate glass sheets of thickness 100 μm was investigated with emphasis on effective cutting speed (Veff) and mechanical strength of diced samples. The process parameters including the laser fluence (F), overlap ratio (r) of the laser beam and polarization direction were varied at a fixed pulse repetition rate f = 1 kHz to find the optimal process condition that maximizes Veff and edge strength. A three-point bending test was performed to evaluate the front-side and back-side bending (edge) strength of the laser-cut samples. Veff was proportional to F unless r exceeded a critical value, at which excessive energy began to be delivered at the same spot. The front-side edge strength was bigger than the back-side strength because of the back-side damages such as chipping. Good edge strength, as high as ∼280 MPa (front-side) and ∼230 MPa (back-side), was obtained at F = 19 J/m2, r = 0.99, with laser polarization vertical to the cutting path.

Side-to-Side Cold Welding for Controllable Nanogap Formation from "Dumbbell" Ultrathin Gold Nanorods.

Dai, Gaole; Wang, Binjun; Xu, Shang; Lu, Yang; Shen, Yajing

2016-06-01

Cold welding has been regarded as a promising bottom-up nanofabrication technique because of its ability to join metallic nanostructures at room temperature with low applied stress and without introducing damage. Usually, the cold welding process can be done instantaneously for ultrathin nanowires (diameter <10 nm) in "head-to-head" joining. Here, we demonstrate that "dumbbell" shaped ultrathin gold nanorods can be cold welded in the "side-to-side" mode in a highly controllable manner and can form an extremely small nanogap via a relatively slow welding process (up to tens of minutes, allowing various functional applications). By combining in situ high-resolution transmission electron microscopic analysis and molecular dynamic simulations, we further reveal the underlying mechanism for this "side-to-side" welding process as being dominated by atom kinetics instead of thermodynamics, which provides critical insights into three-dimensional nanosystem integration as well as the building of functional nanodevices.

Space ultra-vacuum facility and method of operation

A wake shield space processing facility (10) for maintaining ultra-high levels of vacuum is described. The wake shield (12) is a truncated hemispherical section having a convex side (14) and a concave side (24). Material samples (68) to be processed are located on the convex side of the shield, which faces in the wake direction in operation in orbit. Necessary processing fixtures (20) and (22) are also located on the convex side. Support equipment including power supplies (40, 42), CMG package (46) and electronic control package (44) are located on the convex side (24) of the shield facing the ram direction. Prior to operation in orbit the wake shield is oriented in reverse with the convex side facing the ram direction to provide cleaning by exposure to ambient atomic oxygen. The shield is then baked-out by being pointed directed at the sun to obtain heating for a suitable period.

Sugar-sweetened beverages and added sugars (monosaccharides and disaccharides) in the diet are associated with obesity, diabetes, and cardiovascular disease, which are all risk factors for decline in physical function among older adults. The aim of this study was to examine the association between added sugars in the diet and incidence of frailty in older people. Data were taken from 1973 Spanish adults ≥60 y old from the Seniors-ENRICA cohort. In 2008-2010 (baseline), consumption of added sugars (including those in fruit juices) was obtained using a validated diet history. Study participants were followed up until 2012-2013 to assess frailty based on Fried's criteria. Statistical analyses were performed with logistic regression adjusted for age, sex, education, smoking status, body mass index, energy intake, self-reported comorbidities, Mediterranean Diet Adherence Score (excluding sweetened drinks and pastries), TV watching time, and leisure-time physical activity. Compared with participants consuming <15 g/d added sugars (lowest tertile), those consuming ≥36 g/d (highest tertile) were more likely to develop frailty (OR: 2.27; 95% CI: 1.34, 3.90; P-trend = 0.003). The frailty components "low physical activity" and "unintentional weight loss" increased dose dependently with added sugars. Association with frailty was strongest for sugars added during food production. Intake of sugars naturally appearing in foods was not associated with frailty. The consumption of added sugars in the diet of older people was associated with frailty, mainly when present in processed foods. The frailty components that were most closely associated with added sugars were low level of physical activity and unintentional weight loss. Future research should determine whether there is a causal relation between added sugars and frailty.

Interaction of Physical and Chemical Processes Controlling the Environmental Fate and Transport of Lampricides Through Stream-Hyporheic Systems

NASA Astrophysics Data System (ADS)

Hixson, J.; Ward, A. S.; Schmadel, N.; McConville, M.; Remucal, C.

The transport and fate of contaminants of emerging concern through the environment is complicated by the heterogeneity of natural systems and the unique reaction pathways of individual compounds. Our current evaluation of risk is often simplified to controls assumed to be homogeneous in space and time. However, we know spatial heterogeneity and time-variable reaction rates complicate predictions of environmental transport and fate, and therefore risk. These complications are the result of the interactions between the physical and chemical systems and the time-variable equilibrium that exists between the two. Compounds that interact with both systems, such as photolytic compounds, require that both components are fully understood in order to predict transport and fate. Release of photolytic compounds occurs through both unintentional releases and intentional loadings. Evaluating risks associated with unintentional releases and implementing best management practices for intentional releases requires an in-depth understanding of the sensitivity of photolytic compounds to external controls. Lampricides, such as 3-trifluoromethyl-4-nitrophenol (TFM), are broadly applied in the Great Lakes system to control the population of invasive sea lamprey. Over-dosing can yield fish kills and other detrimental impacts. Still, planning accounts for time of passage and dilution, but not the interaction of the physical and chemical systems (i.e., storage in the hyporheic zone and time-variable decay rates). In this study, we model a series of TFM applications to test the efficacy of dosing as a function of system characteristics. Overall, our results demonstrate the complexity associated with photo-sensitive compounds through stream-hyporheic systems, and highlight the need to better understand how physical and chemical systems interact to control transport and fate in the environment.

The present study recorded both behavioral data and event-related brain potentials to examine the effectiveness of a perception-only training and a perception-plus-production training procedure on the intentional and unintentional perception of lexical tone by native English listeners. In the behavioral task, both the perception-only and the perception-plus-production groups improved on the tone discrimination abilities after the training session. Moreover, the participants in both groups generalized the improvements gained through the trained stimuli to the untrained stimuli. In the ERP task, the Mismatch Negativity was smaller in the post-training task than in the pre-training task. However, the two training groups did not differ in tone processing at the intentional or unintentional level after training. These results suggest that the employment of the motor system does not specifically benefit the tone perceptual skills. Furthermore, the present study investigated whether some tone pairs are more easily confused than others by native English listeners, and whether the order of tone presentation influences non-native tone discrimination. In the behavioral task, Tone2-Tone1 (rising-level) and Tone2-Tone4 (rising-falling) were the most difficult tone pairs, while Tone1-Tone2 and Tone4-Tone2 were the easiest tone pairs, even though they involved the same tone contrasts respectively. In the ERP task, the native English listeners had good discrimination when Tone2 and Tone4 were embedded in strings of Tone1, while poor discrimination when Tone1 was inserted in the context of Tone2 or Tone4. These asymmetries in tone perception might be attributed to the interference of native intonation system and can be altered by training. Copyright © 2015 Elsevier B.V. All rights reserved.

Unintentional force changes in cyclical tasks performed by an abundant system: Empirical observations and a dynamical model.

The study explored unintentional force changes elicited by removing visual feedback during cyclical, two-finger isometric force production tasks. Subjects performed two types of tasks at 1Hz, paced by an auditory metronome. One - Force task - required cyclical changes in total force while maintaining the sharing, defined as relative contribution of a finger to total force. The other task - Share task - required cyclical changes in sharing while keeping total force unchanged. Each trial started under full visual feedback on both force and sharing; subsequently, feedback on the variable that was instructed to stay constant was frozen, and finally feedback on the other variable was also removed. In both tasks, turning off visual feedback on total force elicited a drop in the mid-point of the force cycle and an increase in the peak-to-peak force amplitude. Turning off visual feedback on sharing led to a drift of mean share toward 50:50 across both tasks. Without visual feedback there was consistent deviation of the two force time series from the in-phase pattern (typical of the Force task) and from the out-of-phase pattern (typical of the Share task). This finding is in contrast to most earlier studies that demonstrated only two stable patterns, in-phase and out-of-phase. We interpret the results as consequences of drifts of parameters in a dynamical system leading in particular to drifts in the referent finger coordinates toward their actual coordinates. The relative phase desynchronization is caused by the right-left differences in the hypothesized drift processes, consistent with the dynamic dominance hypothesis. Copyright © 2017 IBRO.

The Impact of Sonication on the Surface Quality of Single-Walled Carbon Nanotubes.

PubMed

Koh, Byumseok; Cheng, Wei

2015-08-01

Sonication process is regularly adopted for dispersing single-walled carbon nanotubes (SWCNTs) in an aqueous medium. This can be achieved by either covalent functionalization of SWCNTs with strong acid or by noncovalent functionalization using dispersants that adsorb onto the surface of SWCNTs during dispersion. Because the dispersion process is usually performed using sonication, unintentional free radical formation during sonication process may induce covalent modification of SWCNT surface. Herein, we have systematically investigated the status of SWCNT surface modification under various sonication conditions using Raman spectroscopy. Comparing ID /IG (Raman intensities between D and G bands) ratio of SWCNTs under various sonication conditions suggests that typical sonication conditions (1-6 h bath sonication with sonication power between 3 and 80 W) in aqueous media do not induce covalent modification of SWCNT surface. In addition, we confirm that SWCNT dispersion with single-stranded DNA (ssDNA) involves noncovalent adsorption of ssDNA onto the surface of SWCNTs, but not covalent linkage between ssDNA and SWCNT surface. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association.

The Public Health Challenge of Consumer Non-Compliance to Toy Product Recalls and Proposed Solutions

PubMed Central

Yu, Xiayang

2018-01-01

This paper addresses the public health issue of toy product recalls in the United States, an under-addressed topic in scholarly literature, yet highly relevant to the prevention of pediatric injuries. Toy-related injuries led to 274,000 emergency room visits and seven fatalities in 2016 in the United States, and toy-related injury rates have remained stable over the last five years despite declining incidences of recalls. While dangerous toys not being recalled and the misuse of “safe” products are possible contributing factors, consumer non-response to recall notices also contributes to unintentional child injury from dangerous toys. We discuss the process of recalling toys, and the role of the U.S. Consumer Product Safety Commission in that process. We also review potential factors behind significant consumer non-response to recall notifications, citing economic and psychological theories as explanations for the actions of multiple stakeholders in the recall process. We close by proposing reforms at the regulatory, consumer, and retailer levels that might boost compliance with recall notifications and ultimately reduce injury morbidity and mortality.

Harmonisation of ICD-11 and DSM-V: opportunities and challenges.

PubMed

First, Michael B

2009-11-01

Differences in the ICD-10 and DSM-IV definitions for the same disorder impede international communication and research efforts. The forthcoming parallel development of DSM-V and ICD-11 offers an opportunity to harmonise the two classifications. This paper aims to facilitate the harmonisation process by identifying diagnostic differences between the two systems. DSM-IV-TR criteria sets and the ICD-10 Diagnostic Criteria for Research were compared and categorised into those with identical definitions, those with conceptually based differences and those in which differences are not conceptually based and appear to be unintentional. Of the 176 criteria sets in both systems, only one, transient tic disorder, is identical. Twenty-one per cent had conceptually based differences and 78% had non-conceptually based differences. Harmonisation of criteria sets, especially those with non-conceptually based differences, should be prioritised in the DSM-V and ICD-11 development process. Prior experience with the DSM-IV and ICD-10 harmonisation effort suggests that for the process to be successful steps should be taken as early as possible.

Impurity gettering in semiconductors

1995-06-20

A process for impurity gettering in a semiconductor substrate or device such as a silicon substrate or device is disclosed. The process comprises hydrogenating the substrate or device at the back side thereof with sufficient intensity and for a time period sufficient to produce a damaged back side. Thereafter, the substrate or device is illuminated with electromagnetic radiation at an intensity and for a time period sufficient to cause the impurities to diffuse to the back side and alloy with a metal there present to form a contact and capture the impurities. The impurity gettering process also can function to simultaneously passivate defects within the substrate or device, with the defects likewise diffusing to the back side for simultaneous passivation. Simultaneously, substantially all hydrogen-induced damage on the back side of the substrate or device is likewise annihilated. Also taught is an alternate process comprising thermal treatment after hydrogenation of the substrate or device at a temperature of from about 500 C to about 700 C for a time period sufficient to cause the impurities to diffuse to the damaged back side thereof for subsequent capture by an alloying metal. 1 fig.

Blume, Ingo; Baker, Richard W.

1990-01-01

A pervaporation process for separating organic contaminants from evaporator condensate streams is disclosed. The process employs a permselective membrane that is selectively permeable to an organic component of the condensate. The process involves contacting the feed side of the membrane with a liquid condensate stream, and withdrawing from the permeate side a vapor enriched in the organic component. The driving force for the process is the in vapor pressure across the membrane. This difference may be provided for instance by maintaining a vacuum on the permeate side, or by condensing the permeate. The process offers a simple, economic alternative to other separation techniques.

Basins of attraction in human balance

Falls are a recognized risk factor for unintentional injuries among older adults, accounting for a large proportion of fractures, emergency department visits, and urgent hospitalizations. Human balance and gait research traditionally uses linear or qualitative tests to assess and describe human motion; however, human motion is neither a simple nor a linear process. The objective of this research is to identify and to learn more about what factors affect balance using nonlinear dynamical techniques, such as basin boundaries. Human balance data was collected using dual force plates for leans using only ankle movements as well as for unrestricted leans. Algorithms to describe the basin boundary were created and compared based on how well each method encloses the experimental data points as well as captures the differences between the two leaning conditions.

Persistent organic pollutants (POPs) can travel thousands of miles, accumulate in the food chain, and persist in the environment, taking as long as centuries to degrade. POPs are known to play a role in birth defects, cancer, immune system dysfunction, and reproductive problems in wildlife. While the effects of POPs on human health are unclear, many researchers believe that long-term exposure contributes to increasing rates of birth defects, fertility problems, greater susceptibility to disease, diminished intelligence, and certain cancers. Twelve POPs have been identified by the United Nations Environment Programme as requiring urgent regulatory attention. They include the pesticides aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, hexachlorobenzene, mirex, and toxaphene. Of the remaining three POPs, polychlorinated biphenyls are industrial products (used in electrical transformers), and dioxins and furans are unintentional by-products of industrial processes.

The Stroop effect in English-Japanese bilinguals: the effect of phonological similarity.

PubMed

Sumiya, Hiromi; Healy, Alice F

2008-01-01

English-Japanese bilinguals performed a Stroop color-word interference task with both English and Japanese stimuli and responded in both English and Japanese. The Japanese stimuli were either the traditional color terms (TCTs) written in Hiragana or loanwords (LWs) from English written in Katakana. Both within-language and between-language interference were found for all combinations of stimuli and responses. The between-language interference was larger for Katakana LWs (phonologically similar to English) than for Hiragana TCTs, especially with Japanese responses. The magnitude of this phonological effect increased with self-rated reading fluency in Japanese. Overall responding was slower and the Stroop effect larger with English than with Japanese stimuli. These results suggest that unintentional lexical access elicits automatic phonological processing even with intermediate-level reading proficiency.

Biological Movement and Laws of Physics.

PubMed

Latash, Mark L

2017-07-01

Living systems may be defined as systems able to organize new, biology-specific, laws of physics and modify their parameters for specific tasks. Examples include the force-length muscle dependence mediated by the stretch reflex, and the control of movements with modification of the spatial referent coordinates for salient performance variables. Low-dimensional sets of referent coordinates at a task level are transformed to higher-dimensional sets at lower hierarchical levels in a way that ensures stability of performance. Stability of actions can be controlled independently of the actions (e.g., anticipatory synergy adjustments). Unintentional actions reflect relaxation processes leading to drifts of corresponding referent coordinates in the absence of changes in external load. Implications of this general framework for movement disorders, motor development, motor skill acquisition, and even philosophy are discussed.

Influence of Hybrid Perovskite Fabrication Methods on Film Formation, Electronic Structure, and Solar Cell Performance

2017-01-01

Hybrid organic/inorganic halide perovskites have lately been a topic of great interest in the field of solar cell applications, with the potential to achieve device efficiencies exceeding other thin film device technologies. Yet, large variations in device efficiency and basic physical properties are reported. This is due to unintentional variations during film processing, which have not been sufficiently investigated so far. We therefore conducted an extensive study of the morphology and electronic structure of a large number of CH3NH3PbI3 perovskite where we show how the preparation method as well as the mixing ratio of educts methylammonium iodide and lead(II) iodide impact properties like film formation, crystal structure, density of states, energy levels, and ultimately the solar cell performance.

The effect of hearing aid technologies on listening in an automobile.

PubMed

Wu, Yu-Hsiang; Stangl, Elizabeth; Bentler, Ruth A; Stanziola, Rachel W

2013-06-01

Communication while traveling in an automobile often is very difficult for hearing aid users. This is because the automobile/road noise level is usually high, and listeners/drivers often do not have access to visual cues. Since the talker of interest usually is not located in front of the listener/driver, conventional directional processing that places the directivity beam toward the listener's front may not be helpful and, in fact, could have a negative impact on speech recognition (when compared to omnidirectional processing). Recently, technologies have become available in commercial hearing aids that are designed to improve speech recognition and/or listening effort in noisy conditions where talkers are located behind or beside the listener. These technologies include (1) a directional microphone system that uses a backward-facing directivity pattern (Back-DIR processing), (2) a technology that transmits audio signals from the ear with the better signal-to-noise ratio (SNR) to the ear with the poorer SNR (Side-Transmission processing), and (3) a signal processing scheme that suppresses the noise at the ear with the poorer SNR (Side-Suppression processing). The purpose of the current study was to determine the effect of (1) conventional directional microphones and (2) newer signal processing schemes (Back-DIR, Side-Transmission, and Side-Suppression) on listener's speech recognition performance and preference for communication in a traveling automobile. A single-blinded, repeated-measures design was used. Twenty-five adults with bilateral symmetrical sensorineural hearing loss aged 44 through 84 yr participated in the study. The automobile/road noise and sentences of the Connected Speech Test (CST) were recorded through hearing aids in a standard van moving at a speed of 70 mph on a paved highway. The hearing aids were programmed to omnidirectional microphone, conventional adaptive directional microphone, and the three newer schemes. CST sentences were presented from the side and back of the hearing aids, which were placed on the ears of a manikin. The recorded stimuli were presented to listeners via earphones in a sound-treated booth to assess speech recognition performance and preference with each programmed condition. Compared to omnidirectional microphones, conventional adaptive directional processing had a detrimental effect on speech recognition when speech was presented from the back or side of the listener. Back-DIR and Side-Transmission processing improved speech recognition performance (relative to both omnidirectional and adaptive directional processing) when speech was from the back and side, respectively. The performance with Side-Suppression processing was better than with adaptive directional processing when speech was from the side. The participants' preferences for a given processing scheme were generally consistent with speech recognition results. The finding that performance with adaptive directional processing was poorer than with omnidirectional microphones demonstrates the importance of selecting the correct microphone technology for different listening situations. The results also suggest the feasibility of using hearing aid technologies to provide a better listening experience for hearing aid users in automobiles. American Academy of Audiology.

Unintended and in situ amorphisation of pharmaceuticals.

PubMed

Priemel, P A; Grohganz, H; Rades, T

2016-05-01

Amorphisation of poorly water-soluble drugs is one approach that can be applied to improve their solubility and thus their bioavailability. Amorphisation is a process that usually requires deliberate external energy input. However, amorphisation can happen both unintentionally, as in process-induced amorphisation during manufacturing, or in situ during dissolution, vaporisation, or lipolysis. The systems in which unintended and in situ amorphisation has been observed normally contain a drug and a carrier. Common carriers include polymers and mesoporous silica particles. However, the precise mechanisms by which in situ amorphisation occurs are often not fully understood. In situ amorphisation can be exploited and performed before administration of the drug or possibly even within the gastrointestinal tract, as can be inferred from in situ amorphisation observed during in vitro lipolysis. The use of in situ amorphisation can thus confer the advantages of the amorphous form, such as higher apparent solubility and faster dissolution rate, without the disadvantage of its physical instability.

Secondary electron emission and its role in the space environment

2018-01-01

The role of dust in the space environment is of increasing interest in recent years and also the fast development of fusion devices with a magnetic confinement brought new issues in the plasma-surface interaction. Among other processes, secondary electron emission plays an important role for dust charging in interplanetary space and its importance increases at and above the surfaces of airless bodies like planets, moons, comets or asteroids. A similar situation can be found in many industrial applications where the dust is a final product or an unintentional impurity. The present paper reviews the progress in laboratory investigations of the secondary emission process as well as an evolution of the modeling of the interaction of energetic electrons with dust grains of different materials and sizes. The results of the model are discussed in view of latest laboratory simulations and they are finally applied on the estimation of an interaction of the solar wind and magnetospheric plasmas with the dust attached to or levitating above the lunar surface.

Simulation study of the initial crystallization processes of poly(3-hexylthiophene) in solution: ordering dynamics of main chains and side chains.

PubMed

Takizawa, Yuumi; Shimomura, Takeshi; Miura, Toshiaki

2013-05-23

We study the initial nucleation dynamics of poly(3-hexylthiophene) (P3HT) in solution, focusing on the relationship between the ordering process of main chains and that of side chains. We carried out Langevin dynamics simulation and found that the initial nucleation processes consist of three steps: the ordering of ring orientation, the ordering of main-chain vectors, and the ordering of side chains. At the start, the normal vectors of thiophene rings aligned in a very short time, followed by alignment of main-chain end-to-end vectors. The flexible side-chain ordering took almost 5 times longer than the rigid-main-chain ordering. The simulation results indicated that the ordering of side chains was induced after the formation of the regular stack structure of main chains. This slow ordering dynamics of flexible side chains is one of the factors that cause anisotropic nuclei growth, which would be closely related to the formation of nanofiber structures without external flow field. Our simulation results revealed how the combined structure of the planar and rigid-main-chain backbones and the sparse flexible side chains lead to specific ordering behaviors that are not observed in ordinary linear polymer crystallization processes.

Do Young Heroin Users in Madrid, Barcelona and Seville have Sufficient Knowledge of the Risk Factors for Unintentional Opioid Overdose?

To identify the self-perceived reasons for unintentional opioid overdose of young heroin users in three Spanish cities and their agreement with objective risk factors for overdose. Computer-Assisted Personal Interviews (CAPI) were held with 991 street-recruited current heroin users aged 18–30. The general reasons for overdose and the reasons for the last overdose suffered were explored with open-ended (OEQs) and pre-coded questions (PCQs). Limited knowledge of overdose risk factors was defined as mention of fewer than two objective risk factors for unintentional overdose in the OEQ. Univariate, bivariate, and logistic regression methods were used. 77.8% (Seville), 64.9% (Madrid) and 57.2% (Barcelona) of participants have limited knowledge of overdose risk factors. Residence in Seville and not having attended courses or meetings on overdoses were significantly associated with limited knowledge, after adjusting for other factors. The most frequently identified general reasons in OEQ or PCQ were using heroin in large amounts (66.8%), together with tranquilizers (62.0%), adulterated (60.7%), or purer than usual (57.6%). Most reasons were selected more frequently in PCQ than in OEQ, especially rapid injection of the entire dose and using heroin shortly after using tranquilizers or alcohol, by injection, or after a period of abstinence. The results were similar for overdoses suffered by participants. Most young heroin users do not have sufficient knowledge of overdose risk factors, especially the use of heroin by injection, after a period of abstinence, or together with alcohol or methadone. Specific informational or educational programs adapted to the local context are critically needed. PMID:16739049

Unintentional consequences of dual mode plasma reactors: Implications for upscaling lab-record silicon surface passivation by silicon nitride

NASA Astrophysics Data System (ADS)

Tong, Jingnan; To, Alexander; Lennon, Alison; Hoex, Bram

2017-08-01

Silicon nitride (SiN x ) synthesised by low-temperature plasma enhanced chemical vapour deposition (PECVD) is the most extensively used antireflection coating for crystalline silicon solar cells because of its tunable refractive index in combination with excellent levels of surface and bulk passivation. This has attracted a significant amount of research on developing SiN x films towards an optimal electrical and optical performance. Typically, recipes are first optimised in lab-scale reactors and subsequently, the best settings are transferred to high-throughput reactors. In this paper, we show that for one particular, but widely used, PECVD reactor configuration this upscaling is severely hampered by an important experimental artefact. Specifically, we report on the unintentional deposition of a dual layer structure in a dual mode AK 400 plasma reactor from Roth & Rau which has a significant impact on its surface passivation performance. It is found that the radio frequency (RF) substrate bias ignites an unintentional depositing plasma before the ignition of the main microwave (MW) plasma. This RF plasma deposits a Si-rich intervening SiN x layer (refractive index = 2.4) while using a recipe for stoichiometric SiN x . This layer was found to be 18 nm thick in our case and had an extraordinary impact on the Si surface passivation, witnessed by a reduction in effective surface recombination velocity from 22.5 to 6.2 cm/s. This experimental result may explain some “out of the ordinary” excellent surface passivation results reported recently for nearly stoichiometric SiN x films and has significant consequences when transferring these results to high-throughput deposition systems.

Honduras has the second highest incidence of violence in the Americas. The aim of this study is to explore the number and mechanism of fatal injuries, non-fatal injuries and the sequelae of these injuries due to violence. This is compared with unintentional injuries, in the capital of Honduras for 2001, with a view to better-targeted prevention. Data for non-fatal injuries was retrospectively obtained from medical records of all admissions from the public Emergency Department in Tegucigalpa for 2001. Data on fatal injuries were obtained from the national forensic department. All injuries were reviewed for intention, mechanism and age group. There were 1631 (rate 138/100,000) fatal injuries recorded for 2001 in Tegucigalpa. Of these, 1149 (70.4%) were due to violence, compared to 355 (21.8%) due to unintentional injuries and 127 (7.8%) of unknown intent. Homicides accounted for 1044 (64%), suicides 105 (6.4%) and unintentional deaths 355 (22%). Firearms were the leading cause of death in the homicide group (84.3%). In addition 1592 (rate 235/100,000) non-fatal injuries were documented for people 15 years and above, with 1228 (77.1%) caused by violence, of which 640 (52.1%) were caused by firearms. The age group 15-24 years had the highest rates of fatal and non-fatal injuries due to violence. Twenty percent had permanent sequelae as a result of their injuries. Firearm injuries had the highest proportion of sequelae (28.8%). Violence in Tegucigalpa is a major cause of injury resulting in substantial morbidity, mortality and disability, particularly in young individuals. Firearms are the most common form of violence related injury mechanism and carry the highest associated mortality and permanent disability. Prevention programs are urgently needed to address this devastating problem.

Objective: To determine the proportion of unintentional and undetermined firearm related deaths preventable by three safety devices: personalization devices, loaded chamber indicators (LCIs), and magazine safeties. A personalized gun will operate only for an authorized user, a LCI indicates when the gun contains ammunition, and a magazine safety prevents the gun from firing when the ammunition magazine is removed. Design: Information about all unintentional and undetermined firearm deaths from 1991–98 was obtained from the Office of the Chief Medical Examiner for Maryland, and from the Wisconsin Firearm Injury Reporting System for Milwaukee. Data regarding the victim, shooter, weapon, and circumstances were abstracted. Coding rules to classify each death as preventable, possibly preventable, or not preventable by each of the three safety devices were also applied. Results: There were a total of 117 firearm related deaths in our sample, 95 (81%) involving handguns. Forty three deaths (37%) were classified as preventable by a personalized gun, 23 (20%) by a LCI, and five (4%) by a magazine safety. Overall, 52 deaths (44%) were preventable by at least one safety device. Deaths involving children 0–17 (relative risk (RR) 3.3, 95% confidence interval (CI) 2.1 to 5.1) and handguns (RR 8.1, 95% CI 1.2 to 53.5) were more likely to be preventable. Projecting the findings to the entire United States, an estimated 442 deaths might have been prevented in 2000 had all guns been equipped with these safety devices. Conclusion: Incorporating safety devices into firearms is an important injury intervention, with the potential to save hundreds of lives each year. PMID:14693889

An inner-city Emergency Department (ED) visit provides an opportunity for contact with high-risk adolescents for promoting injury prevention. Objectives To identify the prevalence of injuries sustained over the past year by teens presenting to an inner city ED, and to identify factors associated with recent injury to inform future ED-based injury prevention initiatives. Methods Over one year, seven days a week, from 1:00–11:00 PM, patients ages 14–18 years presenting to the ED participated in a survey regarding past-year risk behaviors and injuries. Results Of the entire group of teens presenting to the ED (n=1128) who completed the survey (83.8% response rate), 46% were male, and 58% were African-American. Past-year injuries were reported by 768 (68.1%) of the teens; 475 (61.8%) reported an unintentional injury and 293 (38.1%) reported an intentional injury. One-third of all youth seeking care reported a past-year sports-related injury (34.5%) or an injury related to driving or riding in a car (12.3%), and 8.2% reported a gun-related injury. Logistic regression found binge drinking (adjusted odds ratio [AOR]=1.95) and illicit weapon carrying (AOR=2.31) predicted a past-year intentional injury. African American youth (AOR=0.56) and those receiving public assistance (AOR=0.73) were less likely to report past-year unintentional injuries. Conclusions Adolescents seeking care in an inner city ED, regardless of reason for seeking care, report an elevated prevalence of recent injury including violence. Future injury screening and prevention efforts should consider universal screening of all youth seeking ED care. PMID:20149570

Introduction Unintentional injuries to children in the outdoors have a significant impact on child mortality, development and healthcare costs. This paper presents the findings of a systematic review about the effectiveness of programs that provided information, advice or education about the prevention of unintentional injuries to children under 15 years during outdoor play and leisure. Methods A structured search strategy was conducted in a range of databases. All report titles and abstracts were screened using pre-defined criteria. Included reports were quality appraised using a modified Graphical Appraisal Tool for Epidemiological studies (GATE) tool. All quality appraisals and data extraction were checked by a second reviewer. If not provided in the original reports, ORs and mean differences were calculated, where sufficient data were available. Results Twenty-three studies met the inclusion criteria. There was a paucity of robust study designs. The majority of studies only reported a short-term follow-up of intermediate outcome measures. Only two studies measured injury rates; both reported a reduction, but both studies also had considerable methodological weaknesses. The five studies that measured the use of protective equipment reported mixed results, although there is some evidence that suggests that more extensive educational programs (such as health fairs and media campaigns) increase their use. The 20 studies that measured behaviour, attitude or knowledge outcomes reported highly mixed results. Discussion Methodological weaknesses of the included studies limit support for a particular course of action. To better inform policy and practice, future research should (1) use robust study designs and (2) not rely on short-term proxy outcome measures. PMID:21890579

The aims of this literature review are to (1) summarise how computer and mobile technology-based health behaviour change applications have been evaluated in unintentional injury prevention, (2) describe how these successes can be applied to injury-prevention programmes in the future and (3) identify research gaps. Studies included in this systematic review were education and behaviour change intervention trials and programme evaluations in which the intervention was delivered by either a computer or mobile technology and addressed an unintentional injury prevention topic. Articles were limited to those published in English and after 1990. Among the 44 technology-based injury-prevention studies included in this review, 16 studies evaluated locally hosted software programmes, 4 studies offered kiosk-based programmes, 11 evaluated remotely hosted internet programmes, 2 studies used mobile technology or portable devices and 11 studies evaluated virtual-reality interventions. Locally hosted software programmes and remotely hosted internet programmes consistently increased knowledge and behaviours. Kiosk programmes showed evidence of modest knowledge and behaviour gains. Both programmes using mobile technology improved behaviours. Virtual-reality programmes consistently improved behaviours, but there were little gains in knowledge. No studies evaluated text-messaging programmes dedicated to injury prevention. There is much potential for computer-based programmes to be used for injury-prevention behaviour change. The reviewed studies provide evidence that computer-based communication is effective in conveying information and influencing how participants think about an injury topic and adopt safety behaviours.

The unintentional usage of adrenaline auto-injectors may cause injury to caregivers or patients. To prevent such incidents, we assessed the causative factors of these incidents. The Anaphylaxis Working Group of the Japanese Society of Pediatric Allergy and Clinical Immunology requested that society members register cases in which adrenaline auto-injectors were unintentionally used. One hundred cases were reported from June 2015 to March 2016. We identified the root causes of 70 child and 25 adult cases, separately. The incidents occurred with repeated prescriptions as well as the first prescription. Three cases resulted in a failure to administer an adrenaline auto-injector to children with anaphylaxis. Four caregivers used it with improper application (epilepsy or enteritis). Among the child cases, the median age at the time of the incident was 5.5 years (range, 2-14 years). Five children injected the adrenaline auto-injector on their own body trunk. Twenty children were not the allergic patients themselves. Improper management protocol of the device and the child's development were concomitantly involved in most of the cases. A variety of human behaviors were identified as the root causes in the adult cases. At least 34 cases were associated with mix-ups between the actual and training device. Health workers should provide sufficient education regarding safety use of adrenaline auto-injector for caregivers tailored to their experience levels at both first and repeated prescriptions. Such education must cover anticipatory behavior based on normal child development. Devices should also be further improved to prevent such incidents. Copyright © 2018 Japanese Society of Allergology.

To determine the relationships between malnutrition and nutrition-related conditions according to the European Society of Clinical Nutrition and Metabolism (ESPEN) consensus and guidelines and clinical outcomes in postacute rehabilitation. Of 102 eligible inpatients, 95 (84.5 years old, 63.2% women) fulfilled inclusion criteria: aged ≥70 years, body mass index <30kg/m 2 , admission for rehabilitation. Mini-Nutritional Assessment-Short Form (MNA-SF≤11) identified patients "at risk" and ESPEN basic and etiology based definitions were applied. Nutrition-related conditions (sarcopenia, frailty, overweight/obesity, micronutrient abnormalities) were determined. We assessed the relationship between these conditions and the clinical and rehabilitation outcomes (relative functional gain, rehabilitation efficiency) during hospitalization. All patients were "at risk" by MNA-SF criteria and 31 reported unintentional weight loss >5% in the last year or 2-3kg in the last 6 months. Nineteen fulfilled the ESPEN basic definition, of which 10 had disease-related malnutrition with inflammation and 9 without inflammation, and 20 had cachexia. Sarcopenia (n=44), frailty (n=94), overweight/obesity (n=59), and micronutrient abnormalities (n=70) were frequent. Unintentional weight loss impaired all functional outcomes and increased length of stay [OR=6.04 (2.87-9.22); p<0.001]. In multivariate analysis, relationships between rehabilitation impact indices and the ESPEN basic and etiology-based definitions observed in univariate analysis persisted only (and marginally) for relative functional gain [OR=13.24 (0.96-181.95); p=0.005]. Infrequent in-hospital mortality prevented meaningful analysis of this outcome. ESPEN basic and etiology-based definitions and nutrition related disorders were determined in postacute care. Malnutrition was associated with poor rehabilitation outcomes, mainly due to unintentional weight loss. Copyright © 2017 Elsevier B.V. All rights reserved.

Unresolved medication discrepancies during hospitalization can contribute to adverse drug events, resulting in patient harm. Discrepancies can be reduced by performing medication reconciliation; however, effective implementation of medication reconciliation has proven to be challenging. The goals of the Multi-Center Medication Reconciliation Quality Improvement Study (MARQUIS) are to operationalize best practices for inpatient medication reconciliation, test their effect on potentially harmful unintentional medication discrepancies, and understand barriers and facilitators of successful implementation. Six U.S. hospitals are participating in this quality improvement mentored implementation study. Each hospital has collected baseline data on the primary outcome: the number of potentially harmful unintentional medication discrepancies per patient, as determined by a trained on-site pharmacist taking a "gold standard" medication history. With the guidance of their mentors, each site has also begun to implement one or more of 11 best practices to improve medication reconciliation. To understand the effect of the implemented interventions on hospital staff and culture, we are performing mixed methods program evaluation including surveys, interviews, and focus groups of front line staff and hospital leaders. At baseline the number of unintentional medication discrepancies in admission and discharge orders per patient varies by site from 2.35 to 4.67 (mean=3.35). Most discrepancies are due to history errors (mean 2.12 per patient) as opposed to reconciliation errors (mean 1.23 per patient). Potentially harmful medication discrepancies averages 0.45 per patient and varies by site from 0.13 to 0.82 per patient. We discuss several barriers to implementation encountered thus far. In the end, we anticipate that MARQUIS tools and lessons learned have the potential to decrease medication discrepancies and improve patient outcomes. Clinicaltrials.gov identifier NCT01337063.

Unintentional injury and its prevention in infant: knowledge and self-reported practices of main caregivers

PubMed Central

2014-01-01

Background Unintentional injuries are the major cause of morbidity and mortality in infants. Prevention of unintentional injuries has been shown to be effective with education. Understanding the level of knowledge and practices of caregivers in infant safety would be useful to identify gaps for improvement. Methods A cross-sectional study was conducted in an urban government health clinic in Malaysia among main caregivers of infants aged 11 to 15 months. Face-to-face interviews were conducted using a semi-structured self-designed questionnaire. Responses to the items were categorised by the percentage of correct answers: poor (<50%), moderate (50% – 70%) and good (>70%). Results A total of 403 caregivers participated in the study. Of the 21 items in the questionnaire on knowledge, 19 had good-to-moderate responses and two had poor responses. The two items on knowledge with poor responses were on the use of infant walkers (26.8%) and allowing infants on motorcycles as pillion riders (27.3%). Self-reported practice of infant safety was poor. None of the participants followed all 19 safety practices measured. Eight (42.1%) items on self-reported practices had poor responses. The worst three of these were on the use of baby cots (16.4%), avoiding the use of infant walkers (23.8%) and putting infants to sleep in the supine position (25.6%). Better knowledge was associated with self-reported safety practices in infants (p < 0.05). However, knowledge did not correspond to correct practice, particularly on the use of baby cots, infant walkers and sarong cradles. Conclusion Main caregivers’ knowledge on infant safety was good but self-reported practice was poor. Further research in the future is required to identify interventions that target these potentially harmful practices. PMID:24885332

Voluntary help during a time of need fosters interpersonal gratitude, which has positive social and personal consequences such as improved social relationships, increased reciprocity, and decreased distress. In a behavioral and a functional magnetic resonance imaging (fMRI) experiment, participants played a multiround interactive game where they received pain stimulation. An anonymous partner interacted with the participants and either intentionally or unintentionally (i.e., determined by a computer program) bore part of the participants' pain. In each round, participants either evaluated their perceived pain intensity (behavioral experiment) or transferred an amount of money to the partner (fMRI experiment). Intentional (relative to unintentional) help led to lower experience of pain, higher reciprocity (money allocation), and increased interpersonal closeness toward the partner. fMRI revealed that for the most grateful condition (i.e., intentional help), value-related structures such as the ventromedial prefrontal cortex (vmPFC) showed the highest activation in response to the partner's decision, whereas the primary sensory area and the anterior insula exhibited the lowest activation at the pain delivery stage. Moreover, the vmPFC activation was predictive of the individual differences in reciprocal behavior, and the posterior cingulate cortex (PCC) activation was predictive of self-reported gratitude. Furthermore, using multivariate pattern analysis (MVPA), we showed that the neural activation pattern in the septum/hypothalamus, an area associated with affiliative affect and social bonding, and value-related structures specifically and sensitively dissociated intentional help from unintentional help conditions. These findings contribute to our understanding of the psychological and neural substrates of the experience of interpersonal gratitude and the social consequences of this emotion.

Examine the prevalence of alcohol and its contributory role in unintentional fatal river drowning in Australia to inform strategies for prevention. Cases of unintentional fatal river drowning in Australia, 1-July-2002 to 30-June-2012, were extracted from the National Coronial Information System. Cases with positive alcohol readings found through autopsy or toxicology reports were retained for analysis. Discrete analysis was conducted on cases with a Blood Alcohol Content (BAC) of ≥0.05% (0.05grams of alcohol in every 100 millilitres of blood). Alcohol was known to be involved in 314 cases (40.8%), 279 recorded a positive BAC, 196 (70.3%) recorded a BAC of ≥0.05%. 40.3% of adult victims had a BAC of ≥0.20%. Known alcohol involvement was found to be more likely for victims who drowned as a result of jumping in (χ 2 =7.8; p<0.01), identify as Aboriginal and Torres Strait Islander (χ 2 =8.9; p<0.01) and drowned in the evening (χ 2 =7.8; p<0.01) and early morning (χ 2 =16.1; p<0.01) hours. The number of people who drown with alcohol in their bloodstream is concerning and challenging for prevention. To assist with the prevention of alcohol related river drowning improved data quality, as well as a greater understanding of alcohol's contribution and consumption patterns at rivers (especially those <18 years of age) is required. Alcohol contributes to fatal unintentional drowning in Australian rivers. Although prevention is challenging, better data and exposure studies are the next step to enhance prevention efforts.

Objectives Falls are among the major external causes of unintentional injury and injury-related mortality in the elderly. The aim of this study was to compare the patterns of unintentional fall-related mortalities in two countries with different demographic structure: Slovakia and Austria in 2003–2010. Methods A study was conducted using death certificate data, trends of fall-related mortality in the elderly (over 65 years) in Austria and Slovakia were compared. Crude and age-standardised mortality rates were calculated. Rate ratios were used to quantify differences based on age, sex and country. The role of demographic structure and population ageing was considered. Results The annual average crude mortality for Slovakia was 28.82, for Austria 54.19 per 100 000 person-years. Increasing rates were observed towards higher age in both countries. Males had higher mortality than females (1.18 times higher in Austria, 2.4 higher in Slovakia). In ages over 75 years rates were significantly higher in Austria, compared to Slovakia. Injuries to head (in males) and hip (in females) were most commonly the underlying cause of death. The proportion of populations over 65 and over 80 and rate of their increase were higher in Austria than in Slovakia. Conclusions We conclude that higher proportions of the elderly population of Austria could have contributed to the higher fall-related mortality rates compared to Slovakia, especially in females over 80 years. Our study quantified the differences between two countries with different structure of the elderly population and these findings could be used in planning future needs of health and social services and to plan prevention in countries where a rapid increase in age of the population can be foreseen.

Aboriginal people in British Columbia (BC), especially those residing on Indian reserves, have higher risk of unintentional fall injury than the general population. We test the hypothesis that the disparities are attributable to a combination of socioeconomic status, geographic place, and Aboriginal ethnicity. Within each of 16 Health Service Delivery Areas in BC, we identified three population groups: total population, Aboriginal off-reserve, and Aboriginal on-reserve. We calculated age and gender-standardized relative risks (SRR) of hospitalization due to unintentional fall injury (relative to the total population of BC), during time periods 1999-2003 and 2004-2008, and we obtained custom data from the 2001 and 2006 censuses (long form), describing income, education, employment, housing, proportions of urban and rural dwellers, and prevalence of Aboriginal ethnicity. We studied association of census characteristics with SRR of fall injury, by multivariable linear regression. The best-fitting model was an excellent fit (R 2  = 0.854, p < 0.001) and predicted SRRs very close to observed values for the total, Aboriginal off-reserve, and Aboriginal on-reserve populations of BC. After stepwise regression, the following terms remained: population per room, urban residence, labor force participation, income per capita, and multiplicative interactions of Aboriginal ethnicity with population per room and labor force participation. The disparities are predictable by the hypothesized risk markers. Aboriginal ethnicity is not an independent risk marker: it modifies the effects of socioeconomic factors. Closing the gap in fall injury risk between the general and Aboriginal populations is likely achievable by closing the gaps in socioeconomic conditions.

Unintentional, non-fire-related (UNFR) carbon monoxide (CO) poisoning is a leading cause of poisoning in the United States, but the overall hospital burden is unknown. This study presents patient characteristics and the most recent comprehensive national estimates of UNFR CO-related emergency department (ED) visits and hospitalizations. Data from the 2007 Nationwide Inpatient and Emergency Department Sample of the Hospitalization Cost and Utilization Project were analyzed. The Council of State and Territorial Epidemiologists' CO poisoning case definition was used to classify confirmed, probable, and suspected cases. In 2007, more than 230,000 ED visits (772 visits/million) and more than 22,000 hospitalizations (75 stays/million) were related to UNFR CO poisoning. Of these, 21,304 ED visits (71 visits/million) and 2302 hospitalizations (8 stays/million) were confirmed cases of UNFR CO poisoning. Among the confirmed cases, the highest ED visit rates were among persons aged 0 to 17 years (76 visits/million) and 18 to 44 years (87 visits/million); the highest hospitalization rate was among persons aged 85 years or older (18 stays/million). Women visited EDs more frequently than men, but men were more likely to be hospitalized. Patients residing in a nonmetropolitan area and in the northeast and midwest regions of the country had higher ED visit and hospitalization rates. Carbon monoxide exposures occurred mostly (>60%) at home. The hospitalization cost for confirmed CO poisonings was more than $26 million. Unintentional, non-fire-related CO poisonings pose significant economic and health burden; continuous monitoring and surveillance of CO poisoning are needed to guide prevention efforts. Public health programs should emphasize CO alarm use at home as the main prevention strategy. Published by Elsevier Inc.

The optimal monitoring during sleep with noninvasive positive pressure ventilation (NPPV) has not been validated in children. The aim of the study was to describe on polygraphic (PG) recordings the respiratory events and associated autonomic arousals (AA) and/or 3 % desaturations (DS3%) during nocturnal NPPV. This was a prospective descriptive study performed in the pulmonology unit of a pediatric university hospital. Consecutive patients admitted for routine follow-up of long-term NPPV were enrolled. Nocturnal PG during sleep with NPPV was performed. A second PG was performed after adjustment of the ventilatory settings when a respiratory event occurred more than 50 times/h. The PG tracings of 39 patients (age range 1-18 years) were analyzed. Underlying diagnoses included neuromuscular disease (n = 13), obstructive sleep apnea (n = 15), and lung disease (n = 11). Unintentional leaks, patient-ventilator asynchronies, decrease in ventilatory drive, upper airway obstruction with or without reduction of ventilatory drive, and mixed events were observed in 27, 33, 10, 11, 12, and 3 % of the patients, respectively. A predominant respiratory event was observed in all patients. The mean duration spent with respiratory events was 32 ± 30 % (range 3-96 %) of total recording time. Unintentional leaks were the most frequently associated with AA, whereas patient-ventilator asynchronies were rarely associated with AA or DS3%. In eight re-evaluated patients, a decrease in the main event was observed (p = 0.005). Respiratory events during sleep with NPPV are common in children treated with long-term NPPV. Consequences of respiratory events vary according to the type of event with unintentional leaks being associated preferentially with AA.

SUMMARY Purpose To assess the impact of a voluntary withdrawal of over-the-counter cough and cold medications (OTC CCMs) labeled for children under age 2 years on pediatric ingestions reported to the American Association of Poison Control Centers. Methods Trend analysis of OTC CCMs ingestions in children under the age 6 years resulting from therapeutic errors or unintentional poisonings for 27 months before (pre-) and 15 months after (post-) the October 2007 voluntary withdrawal was conducted. The rates and outcome severity were examined. Results The mean annual rate of therapeutic errors involving OTC CCMs post-withdrawal, in children less than 2-years of age, 45.2/100 000 (95%CI 30.7–66.6) was 54% of the rate pre-withdrawal, 83.8/100 000 (95%CI 67.6–104.0). The decrease was statistically significant p < 0.02. In this age group, there was no difference in the frequency of severe outcomes resulting from therapeutic errors post-withdrawal. There was no significant difference in unintentional poisoning rates post-withdrawal 82.1/100 000 (66.0–102.2) vs. pre-withdrawal 98.3/100 000 (84.4–114.3) (p < 0.21) in children less than 2-years of age. There were no significant reductions in rates of therapeutic errors and unintentional poisonings in children ages 2–5 years, who were not targeted by the withdrawal. Conclusions A significant decrease in annual rates of therapeutic errors in children under 2-years reported to Poison Centers followed the voluntary withdrawal of OTC CCMs for children under age 2-years. Concerns that withdrawal of pediatric medications would paradoxically increase poisonings from parents giving products intended for older age groups to young children are not supported.

Methods Six U.S. hospitals are participating in this quality improvement mentored implementation study. Each hospital has collected baseline data on the primary outcome: the number of potentially harmful unintentional medication discrepancies per patient, as determined by a trained on-site pharmacist taking a “gold standard” medication history. With the guidance of their mentors, each site has also begun to implement one or more of 11 best practices to improve medication reconciliation. To understand the effect of the implemented interventions on hospital staff and culture, we are performing mixed methods program evaluation including surveys, interviews, and focus groups of front line staff and hospital leaders. Discussion At baseline the number of unintentional medication discrepancies in admission and discharge orders per patient varies by site from 2.35 to 4.67 (mean=3.35). Most discrepancies are due to history errors (mean 2.12 per patient) as opposed to reconciliation errors (mean 1.23 per patient). Potentially harmful medication discrepancies averages 0.45 per patient and varies by site from 0.13 to 0.82 per patient. We discuss several barriers to implementation encountered thus far. In the end, we anticipate that MARQUIS tools and lessons learned have the potential to decrease medication discrepancies and improve patient outcomes.

In semiconductor manufacturing, as the design rule has decreased, the ITRS roadmap requires crucial tighter critical dimension (CD) control. CD uniformity is one of the necessary parameters to assure good performance and reliable functionality of any integrated circuit (IC) [1] [2], and towards the advanced technology nodes, it is a challenge to control CD uniformity well. The study of corresponding CD Uniformity by tuning Post-Exposure bake (PEB) and develop process has some significant progress[3], but CD side to side error happening to some line/space pattern are still found in practical application, and the error has approached to over the uniformity tolerance. After details analysis, even though use several developer types, the CD side to side error has not been found significant relationship to the developing. In addition, it is impossible to correct the CD side to side error by electron beam correction as such error does not appear in all Line/Space pattern masks. In this paper the root cause of CD side to side error is analyzed and the PEB module process are optimized as a main factor for improvement of CD side to side error.

Mental rotation is an important paradigm for spatial ability. Mental-rotation tasks are assumed to involve five or three sequential cognitive-processing states, though this has not been demonstrated experimentally. Here, we investigated how processing states alternate during mental-rotation tasks. Inference was carried out using an advanced statistical modelling and data-driven approach - a discriminative hidden Markov model (dHMM) trained using eye-movement data obtained from an experiment consisting of two different strategies: (I) mentally rotate the right-side figure to be aligned with the left-side figure and (II) mentally rotate the left-side figure to be aligned with the right-side figure. Eye movements were found to contain the necessary information for determining the processing strategy, and the dHMM that best fit our data segmented the mental-rotation process into three hidden states, which we termed encoding and searching, comparison, and searching on one-side pair. Additionally, we applied three classification methods, logistic regression, support vector model and dHMM, of which dHMM predicted the strategies with the highest accuracy (76.8%). Our study did confirm that there are differences in processing states between these two of mental-rotation strategies, and were consistent with the previous suggestion that mental rotation is discrete process that is accomplished in a piecemeal fashion.
