Toxicity, mechanism and health effects of some heavy metals

Abstract: Heavy metal toxicity has proven to be a major threat and there are several health risks associated with it. The toxic effects of these metals, even though they do not have any biological role, remain present in some or the other form harmful for the human body and its proper functioning. They sometimes act as a pseudo element of the body while at certain times they may even interfere with metabolic processes. Few metals, such as aluminium, can be removed through elimination activities, while some metals get accumulated in the body and food chain, exhibiting a chronic nature. Various public health measures have been undertaken to control, prevent and treat metal toxicity occurring at various levels, such as occupational exposure, accidents and environmental factors. Metal toxicity depends upon the absorbed dose, the route of exposure and duration of exposure, i.e. acute or chronic. This can lead to various disorders and can also result in excessive damage due to oxidative stress induced by free radical formation. This review gives details about some heavy metals and their toxicity mechanisms, along with their health effects.

Bullying in the Digital Age: A Critical Review and Meta-Analysis of Cyberbullying Research Among Youth

Abstract: Although the Internet has transformed the way our world operates, it has also served as a venue for cyberbullying, a serious form of misbehavior among youth. With many of today's youth experiencing acts of cyberbullying, a growing body of literature has begun to document the prevalence, predictors, and outcomes of this behavior, but the literature is highly fragmented and lacks theoretical focus. Therefore, our purpose in the present article is to provide a critical review of the existing cyberbullying research. The general aggression model is proposed as a useful theoretical framework from which to understand this phenomenon. Additionally, results from a meta-analytic review are presented to highlight the size of the relationships between cyberbullying and traditional bullying, as well as relationships between cyberbullying and other meaningful behavioral and psychological variables. Mixed effects meta-analysis results indicate that among the strongest associations with cyberbullying perpetration were normative beliefs about aggression and moral disengagement, and the strongest associations with cyberbullying victimization were stress and suicidal ideation. Several methodological and sample characteristics served as moderators of these relationships. Limitations of the meta-analysis include issues dealing with causality or directionality of these associations as well as generalizability for those meta-analytic estimates that are based on smaller sets of studies (k < 5). Finally, the present results uncover important areas for future research. We provide a relevant agenda, including the need for understanding the incremental impact of cyberbullying (over and above traditional bullying) on key behavioral and psychological outcomes.

The benefits of playing video games

Abstract: Video games are a ubiquitous part of almost all children's and adolescents' lives, with 97% playing for at least one hour per day in the United States. The vast majority of research by psychologists on the effects of "gaming" has been on its negative impact: the potential harm related to violence, addiction, and depression. We recognize the value of that research; however, we argue that a more balanced perspective is needed, one that considers not only the possible negative effects but also the benefits of playing these games. Considering these potential benefits is important, in part, because the nature of these games has changed dramatically in the last decade, becoming increasingly complex, diverse, realistic, and social in nature. A small but significant body of research has begun to emerge, mostly in the last five years, documenting these benefits. In this article, we summarize the research on the positive effects of playing video games, focusing on four main domains: cognitive, motivational, emotional, and social. By integrating insights from developmental, positive, and social psychology, as well as media psychology, we propose some candidate mechanisms by which playing video games may foster real-world psychosocial benefits. Our aim is to provide strong enough evidence and a theoretical rationale to inspire new programs of research on the largely unexplored mental health benefits of gaming. Finally, we end with a call to intervention researchers and practitioners to test the positive uses of video games, and we suggest several promising directions for doing so.

Youth risk behavior surveillance - United States, 2013

Abstract: Problem: Priority health-risk behaviors contribute to the leading causes of morbidity and mortality among youth and adults. Population-based data on these behaviors at the national, state, and local levels can help monitor the effectiveness of public health interventions designed to protect and promote the health of youth nationwide. Reporting Period Covered: September 2012-December 2013. Description of the System: The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority health-risk behaviors among youth and young adults: 1) behaviors that contribute to unintentional injuries and violence; 2) tobacco use; 3) alcohol and other drug use; 4) sexual behaviors that contribute to unintended pregnancy and sexually transmitted infections (STIs), including human immunodeficiency virus (HIV) infection; 5) unhealthy dietary behaviors; and 6) physical inactivity. In addition, YRBSS monitors the prevalence of obesity and asthma. YRBSS includes a national school-based Youth Risk Behavior Survey (YRBS) conducted by CDC and state and large urban school district school-based YRBSs conducted by state and local education and health agencies. This report summarizes results for 104 health-risk behaviors plus obesity, overweight, and asthma from the 2013 national survey, 42 state surveys, and 21 large urban school district surveys conducted among students in grades 9-12. RESULTS: Results from the 2013 national YRBS indicated that many high school students are engaged in priority health-risk behaviors associated with the leading causes of death among persons aged 10-24 years in the United States. During the 30 days before the survey, 41.4% of high school students nationwide among the 64.7% who drove a car or other vehicle during the 30 days before the survey had texted or e-mailed while driving, 34.9% had drunk alcohol, and 23.4% had used marijuana. During the 12 months before the survey, 14.8% had been electronically bullied, 19.6% had been bullied on school property, and 8.0% had attempted suicide. Many high school students nationwide are engaged in sexual risk behaviors that contribute to unintended pregnancies and STIs, including HIV infection. Nearly half (46.8%) of students had ever had sexual intercourse, 34.0% had had sexual intercourse during the 3 months before the survey (i.e., currently sexually active), and 15.0% had had sexual intercourse with four or more persons during their life. Among currently sexually active students, 59.1% had used a condom during their last sexual intercourse. RESULTS from the 2013 national YRBS also indicate many high school students are engaged in behaviors associated with chronic diseases, such as cardiovascular disease, cancer, and diabetes. During the 30 days before the survey, 15.7% of high school students had smoked cigarettes and 8.8% had used smokeless tobacco. During the 7 days before the survey, 5.0% of high school students had not eaten fruit or drunk 100% fruit juices and 6.6% had not eaten vegetables. More than one-third (41.3%) had played video or computer games or used a computer for something that was not school work for 3 or more hours per day on an average school day. INTERPRETATION: Many high school students engage in behaviors that place them at risk for the leading causes of morbidity and mortality. The prevalence of most health-risk behaviors varies by sex, race/ethnicity, and grade and across states and large urban school districts. Long term temporal changes also have occurred. Since the earliest year of data collection, the prevalence of most health-risk behaviors has decreased (e.g., physical fighting, current cigarette use, and current sexual activity), but the prevalence of other health-risk behaviors has not changed (e.g., suicide attempts treated by a doctor or nurse, having ever used marijuana, and having drunk alcohol or used drugs before last sexual intercourse) or has increased (e.g., having not gone to school because of safety concern and obesity and overweight). Public Health Action: YRBSS data are used widely to compare the prevalence of health-risk behaviors among subpopulations of students; assess trends in health-risk behaviors over time; monitor progress toward achieving 20 national health objectives for Healthy People 2020 and one of the 26 leading health indicators; provide comparable state and large urban school district data; and help develop and evaluate school and community policies, programs, and practices designed to decrease health-risk behaviors and improve health outcomes among youth.

The conclusion calls for developmental scientists to engage in international efforts to promote resilience

Prevalence of Nonsuicidal Self‐Injury in Nonclinical Samples: Systematic Review, Meta‐Analysis and Meta‐Regression

Abstract: Published prevalence estimates of nonsuicidal self-injury (NSSI) among nonclinical samples are highly heterogeneous, raising concerns about their reliability and hindering attempts to explore the alleged increase in NSSI over time. Accordingly, the objectives of this study were to investigate the influence of methodological factors on heterogeneity in NSSI prevalence estimates, explore changes over time, and estimate overall international NSSI prevalence. Results showed that methodological factors contributed over half (51.6%) of the heterogeneity in prevalence estimates, and, after adjusting for these factors, NSSI prevalence did not increase over time. Overall, pooled NSSI prevalence was 17.2% among adolescents, 13.4% among young adults, and 5.5% among adults. Clearly, development of standardized methodology in NSSI research is crucial if accurate estimates are desired.

Insufficient Sleep in Adolescents and Young Adults: An Update on Causes and Consequences

Abstract: sleep loss and associated sleepiness and daytime impair- ments in adolescence are a serious threat to the academic success, health, and safety of our nation's youth and an important public health issue. Understanding the extent and potential short- and long-term repercussions of sleep restriction, as well as the unhealthy sleep practices and environmental factors that contribute to sleep loss in adolescents, is key in setting public policies to mitigate these effects and in counseling patients and families in the clinical setting. This report reviews the current literature on sleep patterns in adoles- cents, factors contributing to chronic sleep loss (ie, electronic media use, caffeine consumption), and health-related consequences, such as depression, increased obesity risk, and higher rates of drowsy driving accidents. The report also discusses the potential role of later school start times as a means of reducing adolescent sleepiness. Pediatrics 2014;134:e921-e932

The new neurometabolic cascade of concussion

Abstract: Objective: To review the underlying pathophysiologic processes of concussive brain injury and relate these neurometabolic changes to clinical sports-related issues such as injury to the developing brain, overuse injury, and repeated concussion. Data Sources: Over 100 articles from both basic science and clinical medical literature selected for relevance to concussive brain injury, postinjury pathophysiology, and recovery of function. Data Synthesis: The primary elements of the pathophysiologic cascade following concussive brain injury include abrupt neuronal depolarization, release of excitatory neurotransmitters, ionic shifts, changes in glucose metabolism, altered cerebral blood flow, and impaired axonal function. These alterations can be correlated with periods of postconcussion vulnerability and with neurobehavioral abnormalities. While the time course of these changes is well understood in experimental animal models, it is only beginning to be characterized following human concussion. Conclusions/Recommendations: Following concussion, cerebral pathophysiology can be adversely affected for days in animals and weeks in humans. Significant changes in cerebral glucose metabolism can exist even in head-injured patients with normal Glasgow Coma Scores, underscoring the need for indepth clinical assessment in an effort to uncover neurocognitive correlates of altered cerebral physiology. Improved guidelines for clinical management of concussion may be formulated as the functional significance and duration of these postinjury neurometabolic derangements are better delineated.

Cooperative Adaptive Cruise Control in Real Traffic Situations

Abstract: Intelligent vehicle cooperation based on reliable communication systems contributes not only to reducing traffic accidents but also to improving traffic flow. Adaptive cruise control (ACC) systems can gain enhanced performance by adding vehicle-vehicle wireless communication to provide additional information to augment range sensor data, leading to cooperative ACC (CACC). This paper presents the design, development, implementation, and testing of a CACC system. It consists of two controllers, one to manage the approaching maneuver to the leading vehicle and the other to regulate car-following once the vehicle joins the platoon. The system has been implemented on four production Infiniti M56s vehicles, and this paper details the results of experiments to validate the performance of the controller and its improvements with respect to the commercially available ACC system.

Prevalence and characteristics of sexual violence, stalking, and intimate partner violence victimization--national intimate partner and sexual violence survey, United States, 2011.

Abstract: Problem/Condition: Sexual violence, stalking, and intimate partner violence are public health problems known to have a negative impact on millions of persons in the United States each year, not only by way of immediate harm but also through negative long-term health impacts. Before implementation of the National Intimate Partner and Sexual Violence Survey (NISVS) in 2010, the most recent detailed national data on the public health burden from these forms of violence were obtained from the National Violence against Women Survey conducted during 1995-1996. This report examines sexual violence, stalking, and intimate partner violence victimization using data from 2011. The report describes the overall prevalence of sexual violence, stalking, and intimate partner violence victimization; racial/ethnic variation in prevalence; how types of perpetrators vary by violence type; and the age at which victimization typically begins. For intimate partner violence, the report also examines a range of negative impacts experienced as a result of victimization, including the need for services. Reporting Period: January-December, 2011. Description of System: NISVS is a national random-digit-dial telephone survey of the noninstitutionalized English- and Spanish-speaking U.S. population aged ≥18 years. NISVS gathers data on experiences of sexual violence, stalking, and intimate partner violence among adult women and men in the United States by using a dual-frame sampling strategy that includes both landline and cellular telephones. The survey was conducted in 50 states and the District of Columbia; in 2011, the second year of NISVS data collection, 12,727 interviews were completed, and 1,428 interviews were partially completed. RESULTS: In the United States, an estimated 19.3% of women and 1.7% of men have been raped during their lifetimes; an estimated 1.6% of women reported that they were raped in the 12 months preceding the survey. The case count for men reporting rape in the preceding 12 months was too small to produce a statistically reliable prevalence estimate. An estimated 43.9% of women and 23.4% of men experienced other forms of sexual violence during their lifetimes, including being made to penetrate, sexual coercion, unwanted sexual contact, and noncontact unwanted sexual experiences. The percentages of women and men who experienced these other forms of sexual violence victimization in the 12 months preceding the survey were an estimated 5.5% and 5.1%, respectively. An estimated 15.2% of women and 5.7% of men have been a victim of stalking during their lifetimes. An estimated 4.2% of women and 2.1% of men were stalked in the 12 months preceding the survey. With respect to sexual violence and stalking, female victims reported predominantly male perpetrators, whereas for male victims, the sex of the perpetrator varied by the specific form of violence examined. Male rape victims predominantly had male perpetrators, but other forms of sexual violence experienced by men were either perpetrated predominantly by women (i.e., being made to penetrate and sexual coercion) or split more evenly among male and female perpetrators (i.e., unwanted sexual contact and noncontact unwanted sexual experiences). In addition, male stalking victims also reported a more even mix of males and females who had perpetrated stalking against them. The lifetime and 12-month prevalences of rape by an intimate partner for women were an estimated 8.8% and 0.8%, respectively; an estimated 0.5% of men experienced rape by an intimate partner during their lifetimes, although the case count for men reporting rape by an intimate partner in the preceding 12 months was too small to produce a statistically reliable prevalence estimate. An estimated 15.8% of women and 9.5% of men experienced other forms of sexual violence by an intimate partner during their lifetimes, whereas an estimated 2.1% of both men and women experienced these forms of sexual violence by a partner in the 12 months before taking the survey. Severe physical violence by an intimate partner (including acts such as being hit with something hard, being kicked or beaten, or being burned on purpose) was experienced by an estimated 22.3% of women and 14.0% of men during their lifetimes and by an estimated 2.3% of women and 2.1% of men in the 12 months before taking the survey. Finally, the lifetime and 12-month prevalence of stalking by an intimate partner for women was an estimated 9.2% and 2.4%, respectively, while the lifetime and 12-month prevalence for men was an estimated 2.5% and 0.8%, respectively. Many victims of sexual violence, stalking, and intimate partner violence were first victimized at a young age. Among female victims of completed rape, an estimated 78.7% were first raped before age 25 years (40.4% before age 18 years). Among male victims who were made to penetrate a perpetrator, an estimated 71.0% were victimized before age 25 years (21.3% before age 18 years). In addition, an estimated 53.8% of female stalking victims and 47.7% of male stalking victims were first stalked before age 25 years (16.3% of female victims and 20.5% of male victims before age 18 years). Finally, among victims of contact sexual violence, physical violence, or stalking by an intimate partner, an estimated 71.1% of women and 58.2% of men first experienced these or other forms of intimate partner violence before age 25 years (23.2% of female victims and 14.1% of male victims before age 18 years). INTERPRETATION: A substantial proportion of U.S. female and male adults have experienced some form of sexual violence, stalking, or intimate partner violence at least once during their lifetimes, and the sex of perpetrators varied by the specific form of violence examined. In addition, a substantial number of U.S. adults experienced sexual violence, stalking, or intimate partner violence during the 12 months preceding the 2011 survey. Consistent with previous studies, the overall pattern of results suggest that women, in particular, are heavily impacted over their lifetime. However, the results also indicate that many men experience sexual violence, stalking, and, in particular, physical violence by an intimate partner. Because of the broad range of short- and long-term consequences known to be associated with these forms of violence, the public health burden of sexual violence, stalking, and intimate partner violence is substantial. RESULTS suggest that these forms of violence frequently are experienced at an early age because a majority of victims experienced their first victimization before age 25 years, with a substantial proportion experiencing victimization in childhood or adolescence. Public Health Action: Because a substantial proportion of sexual violence, stalking, and intimate partner violence is experienced at a young age, primary prevention of these forms of violence must begin early. Prevention efforts should take into consideration that female sexual violence and stalking victimization is perpetrated predominately by men and that a substantial proportion of male sexual violence and stalking victimization (including rape, unwanted sexual contact, noncontact unwanted sexual experiences, and stalking) also is perpetrated by men. CDC seeks to prevent these forms of violence with strategies that address known risk factors for perpetration and by changing social norms and behaviors by using bystander and other prevention strategies. In addition, primary prevention of intimate partner violence is focused on the promotion of healthy relationship behaviors and other protective factors, with the goal of helping adolescents develop these positive behaviors before their first relationships. The early promotion of healthy relationships while behaviors are still relatively modifiable makes it more likely that young persons can avoid violence in their relationships. Language: en

Nonnaïveté among Amazon Mechanical Turk workers: consequences and solutions for behavioral researchers

Abstract: Crowdsourcing services—particularly Amazon Mechanical Turk—have made it easy for behavioral scientists to recruit research participants. However, researchers have overlooked crucial differences between crowdsourcing and traditional recruitment methods that provide unique opportunities and challenges. We show that crowdsourced workers are likely to participate across multiple related experiments and that researchers are overzealous in the exclusion of research participants. We describe how both of these problems can be avoided using advanced interface features that also allow prescreening and longitudinal data collection. Using these techniques can minimize the effects of previously ignored drawbacks and expand the scope of crowdsourcing as a tool for psychological research.

Gender Similarities and Differences

Abstract: Whether men and women are fundamentally different or similar has been debated for more than a century. This review summarizes major theories designed to explain gender differences: evolutionary theories, cognitive social learning theory, sociocultural theory, and expectancy-value theory. The gender similarities hypothesis raises the possibility of theorizing gender similarities. Statistical methods for the analysis of gender differences and similarities are reviewed, including effect sizes, meta-analysis, taxometric analysis, and equivalence testing. Then, relying mainly on evidence from meta-analyses, gender differences are reviewed in cognitive performance (e.g., math performance), personality and social behaviors (e.g., temperament, emotions, aggression, and leadership), and psychological well-being. The evidence on gender differences in variance is summarized. The final sections explore applications of intersectionality and directions for future research.

Dynamic population mapping using mobile phone data

Abstract: During the past few decades, technologies such as remote sensing, geographical information systems, and global positioning systems have transformed the way the distribution of human population is studied and modeled in space and time. However, the mapping of populations remains constrained by the logistics of censuses and surveys. Consequently, spatially detailed changes across scales of days, weeks, or months, or even year to year, are difficult to assess and limit the application of human population maps in situations in which timely information is required, such as disasters, conflicts, or epidemics. Mobile phones (MPs) now have an extremely high penetration rate across the globe, and analyzing the spatiotemporal distribution of MP calls geolocated to the tower level may overcome many limitations of census-based approaches, provided that the use of MP data is properly assessed and calibrated. Using datasets of more than 1 billion MP call records from Portugal and France, we show how spatially and temporarily explicit estimations of population densities can be produced at national scales, and how these estimates compare with outputs produced using alternative human population mapping methods. We also demonstrate how maps of human population changes can be produced over multiple timescales while preserving the anonymity of MP users. With similar data being collected every day by MP network providers across the world, the prospect of being able to map contemporary and changing human population distributions over relatively short intervals exists, paving the way for new applications and a near real-time understanding of patterns and processes in human geography.

Incidence and Trends of Anterior Cruciate Ligament Reconstruction in the United States

Abstract: >> Background: Anterior cruciate ligament (ACL) injury is among the most commonly studied injuries in orthopaedics. The previously reported incidence of ACL injury in the United States has varied considerably and is often based on expert opinion or single insurance databases. Purpose: To determine the incidence of ACL reconstruction (ACLR) in the United States; to identify changes in this incidence between 1994 and 2006; to identify changes in the demographics of ACLR over the same time period with respect to location (inpatient vs outpatient), sex, and age; and to determine the most frequent concomitant procedures performed at the time of ACLR. Study Design: Descriptive epidemiological study. Methods: International Classification of Diseases, 9th Revision (ICD-9) codes 844.2 and 717.83 were used to search the National Hospital Discharge Survey (NHDS) and the National Survey of Ambulatory Surgery (NSAS) for the diagnosis of ACL tear, and the procedure code 81.45 was used to search for ACLR. The incidence of ACLR in 1994 and 2006 was determined by use of US Census Data, and the results were then stratified based on patient age, sex, facility, concomitant diagnoses, and concomitant procedures. Results: The incidence of ACLR in the United States rose from 86,687 (95% CI, 51,844-121,530; 32.9 per 100,000 person-years) in 1994 to 129,836 (95% CI, 94,993-164,679; 43.5 per 100,000 person-years) in 2006 (P = .015). The number of ACLRs increased in patients younger than 20 years and those who were 40 years or older over this 12-year period. The incidence of ACLR in females significantly increased from 10.36 to 18.06 per 100,000 person-years between 1994 and 2006 (P = .0003), while that in males rose at a slower rate, with an incidence of 22.58 per 100,000 person-years in 1994 and 25.42 per 100,000 person-years in 2006. In 2006, 95% of ACLRs were performed in an outpatient setting, while in 1994 only 43% of ACLRs were performed in an outpatient setting. The most common concomitant procedures were partial meniscectomy and chondroplasty. Conclusion: The incidence of ACLR increased between 1994 and 2006, particularly in females as well as those younger than 20 years and those 40 years or older. Research efforts as well as cost-saving measures may be best served by targeting prevention and outcomes measures in these groups. Surgeons should be aware that concomitant injury is common.

The essence of innocence: Consequences of dehumanizing Black children.

Abstract: The social category "children" defines a group of individuals who are perceived to be distinct, with essential characteristics including innocence and the need for protection (Haslam, Rothschild, & Ernst, 2000). The present research examined whether Black boys are given the protections of childhood equally to their peers. We tested 3 hypotheses: (a) that Black boys are seen as less "childlike" than their White peers, (b) that the characteristics associated with childhood will be applied less when thinking specifically about Black boys relative to White boys, and (c) that these trends would be exacerbated in contexts where Black males are dehumanized by associating them (implicitly) with apes (Goff, Eberhardt, Williams, & Jackson, 2008). We expected, derivative of these 3 principal hypotheses, that individuals would perceive Black boys as being more responsible for their actions and as being more appropriate targets for police violence. We find support for these hypotheses across 4 studies using laboratory, field, and translational (mixed laboratory/field) methods. We find converging evidence that Black boys are seen as older and less innocent and that they prompt a less essential conception of childhood than do their White same-age peers. Further, our findings demonstrate that the Black/ape association predicted actual racial disparities in police violence toward children. These data represent the first attitude/behavior matching of its kind in a policing context. Taken together, this research suggests that dehumanization is a uniquely dangerous intergroup attitude, that intergroup perception of children is underexplored, and that both topics should be research priorities.

The global map for traumatic spinal cord injury epidemiology: update 2011, global incidence rate

Abstract: Study design:Literature reviewObjectives:Update the global maps for traumatic spinal cord injury (TSCI) and incorporate methods for extrapolating incidence dataSetting:An initiative of the International Spinal Cord Society (ISCoS) Prevention CommitteeMethods:A search of Medline/Embase was performed (1959-Jun/30/2011) Enhancement of data-quality 'zones' including individual data-ranking as well as integrating regression techniques to provide a platform for continued regional and global estimatesResults:A global-incident rate (2007) is estimated at 23 TSCI cases per million (179 312 cases per annum) Regional data are available from North America (40 per million), Western Europe (16 per million) and Australia (15 per million) Extrapolated regional data are available for Asia-Central (25 per million), Asia-South (21 per million), Caribbean (19 per million), Latin America, Andean (19 per million), Latin America, Central (24 per million), Latin America-Southern (25 per million), Sub-Saharan Africa-Central (29 per million), Sub-Saharan Africa-East (21 per million)Discussion:It is estimated that globally in 2007, there would have been between 133 and 226 thousand incident cases of TSCI from accidents and violence The proportion of TSCI from land transport is decreasing/stable in developed but increasing in developing countries due to trends in transport mode (transition to motorised transport), poor infrastructure and regulatory challenges TSCIs from low falls in the elderly are increasing in developed countries with ageing populations In some developing countries low falls, resulting in TSCI occur while carrying heavy loads on the head in young people In developing countries high-falls feature, commonly from trees, balconies, flat roofs and construction sites TSCI is also due to crush-injuries, diving and violenceConclusion:The online global maps now inform an extrapolative statistical model, which estimates incidence for areas with insufficient TSCI data The accuracy of this methodology will be improved through the use of prospective, standardised-data registriesSpinal Cord advance online publication, 26 February 2013; doi:101038/sc2012158 Language: en

In particular, we provide an overview of research on the presentation, burden, correlates, and treatment of mental disorders following disasters. We also describe challenges to studying the mental health consequences of disasters and discuss the limitations in current methodologies. Finally, we offer directions for future disaster mental health research.

Learning to coexist with wildfire

Abstract: The impacts of escalating wildfire in many regions - the lives and homes lost, the expense of suppression and the damage to ecosystem services - necessitate a more sustainable coexistence with wildfire. Climate change and continued development on fire-prone landscapes will only compound current problems. Emerging strategies for managing ecosystems and mitigating risks to human communities provide some hope, although greater recognition of their inherent variation and links is crucial. Without a more integrated framework, fire will never operate as a natural ecosystem process, and the impact on society will continue to grow. A more coordinated approach to risk management and land-use planning in these coupled systems is needed.

Coming to terms with fear

Abstract: The brain mechanisms of fear have been studied extensively using Pavlovian fear conditioning, a procedure that allows exploration of how the brain learns about and later detects and responds to threats. However, mechanisms that detect and respond to threats are not the same as those that give rise to conscious fear. This is an important distinction because symptoms based on conscious and nonconscious processes may be vulnerable to different predisposing factors and may also be treatable with different approaches in people who suffer from uncontrolled fear or anxiety. A conception of so-called fear conditioning in terms of circuits that operate nonconsciously, but that indirectly contribute to conscious fear, is proposed as way forward.

Global prevalence and incidence of traumatic spinal cord injury

Abstract: BACKGROUND: Spinal cord injury (SCI) is a traumatic event that impacts a patient's physical, psychological, and social well-being and places substantial financial burden on health care systems. To determine the true impact of SCI, this systematic review aims to summarize literature reporting on either the incidence or prevalence of SCI. METHODS: A systematic search was conducted using PubMed, MEDLINE, MEDLINE in process, EMBASE, Cochrane Controlled Trial Register, and Cochrane Database of Systematic Reviews to identify relevant literature published through June 2013. We sought studies that provided regional, provincial/state, or national data on the incidence of SCI or reported estimates of disease prevalence. The level of evidence of each study was rated using a scale that evaluated study design, methodology, sampling bias, and precision of estimates. RESULTS: The initial search yielded 5,874 articles, 48 of which met the inclusion criteria. Forty-four studies estimated the incidence of SCI and nine reported the prevalence, with five discussing both. Of the incidence studies, 14 provided figures at a regional, ten at a state or provincial level and 21 at a national level. The prevalence of SCI was highest in the United States of America (906 per million) and lowest in the Rhone-Alpes region, France (250 per million) and Helsinki, Finland (280 per million). With respect to states and provinces in North America, the crude annual incidence of SCI was highest in Alaska (83 per million) and Mississippi (77 per million) and lowest in Alabama (29.4 per million), despite a large percentage of violence injuries (21.2%). Annual incidences were above 50 per million in the Hualien County in Taiwan (56.1 per million), the central Portugal region (58 per million), and Olmsted County in Minnesota (54.8 per million) and were lower than 20 per million in Taipei, Taiwan (14.6 per million), the Rhone-Alpes region in France (12.7 per million), Aragon, Spain (12.1 per million), Southeast Turkey (16.9 per million), and Stockholm, Sweden (19.5 per million). The highest national incidence was 49.1 per million in New Zealand, and the lowest incidences were in Fiji (10.0 per million) and Spain (8.0 per million). The majority of studies showed a high male-to-female ratio and an age of peak incidence of younger than 30 years old. Traffic accidents were typically the most common cause of SCI, followed by falls in the elderly population. CONCLUSION: This review demonstrates that the incidence, prevalence, and causation of SCI differs between developing and developed countries and suggests that management and preventative strategies need to be tailored to regional trends. The rising aging population in westernized countries also indicates that traumatic SCI secondary to falls may become an increasing public health challenge and that incidence among the elderly may rise with increasing life expectancy.
