In January of 2010, North Carolina (NC) USA implemented state-wide Trauma Triage Destination Plans (TTDPs) to provide standardized guidelines for Emergency Medical Services (EMS) decision making. No study exists to evaluate whether triage behavior has changed for geriatric trauma patients.
The impact of the NC TTDPs was investigated on EMS triage of geriatric trauma patients meeting physiologic criteria of serious injury, primarily based on whether these patients were transported to a trauma center.
This is a retrospective cohort study of geriatric trauma patients transported by EMS from March 1, 2009 through September 30, 2009 (pre-TTDP) and March 1, 2010 through September 30, 2010 (post-TTDP) meeting the following inclusion criteria: (1) age 50 years or older; (2) transported to a hospital by NC EMS; (3) experienced an injury; and (4) meeting one or more of the NC TTDP’s physiologic criteria for trauma (n = 5,345). Data were obtained from the Prehospital Medical Information System (PreMIS). Data collected included proportions of patients transported to a trauma center categorized by specific physiologic criteria, age category, and distance from a trauma center.
The proportion of patients transported to a trauma center pre-TTDP (24.4% [95% CI 22.7%-26.1%]; n = 604) was similar to the proportion post-TTDP (24.4% [95% CI 22.9%-26.0%]; n = 700). For patients meeting specific physiologic triage criteria, the proportions of patients transported to a trauma center were also similar pre- and post-TTDP: systolic blood pressure <90 mmHg (22.5% versus 23.5%); respiratory rate <10 or >29 (23.2% versus 22.6%); and Glascow Coma Scale (GCS) score <13 (26.0% versus 26.4%). Patients aged 80 years or older were less likely to be transported to a trauma center than younger patients in both the pre- and post-TTDP periods.
State-wide implementation of a TTDP had no discernible effect on the proportion of patients 50 years and older transported to a trauma center. Under-triage remained common and became increasingly prevalent among the oldest adults. Research to understand the uptake of guidelines and protocols into EMS practice is critical to improving care for older adults in the prehospital environment.
Bovine viral diarrhea virus (BVDV) is an important infectious disease agent that causes significant reproductive and economic losses in the cattle industry worldwide. Although BVDV infection is known to cause poor fertility in cattle, a greater part of the underlying mechanisms particularly associated with early reproductive losses are not clearly understood. Previous studies reported viral compromise of reproductive function in infected bulls. In females, BVDV infection is thought to be capable of killing the oocyte, embryo or fetus directly, or to induce lesions that result in fetal abortion or malformation. BVDV infections may also induce immune dysfunction, and predispose cattle to other diseases that cause poor health and fertility. Other reports also suggested BVDV-induced disruption of the reproductive endocrine system, and a disruption of leukocyte and cytokine functions in the reproductive organs. More recent studies have provided evidence of viral-induced suppression of endometrial innate immunity that may predispose to uterine disease. Furthermore, there is new evidence that BVDV may potentially disrupt the maternal recognition of pregnancy or the immune protection of the conceptus. This review brings together the previous reports with the more recent findings, and attempts to explain some of the mechanisms linking this important virus to infertility in cattle.
Analysis of human remains and a copper band found in the center of a Late Archaic (ca. 5000–3000 cal BP) shell ring demonstrate an exchange network between the Great Lakes and the coastal southeast United States. Similarities in mortuary practices suggest that the movement of objects between these two regions was more direct and unmediated than archaeologists previously assumed based on “down-the-line” models of exchange. These findings challenge prevalent notions that view preagricultural Native American communities as relatively isolated from one another and suggest instead that wide social networks spanned much of North America thousands of years before the advent of domestication.
The first positive genome-wide association study on gestational length and preterm delivery showed associations with a gene involved in the selenium metabolism. In this study we examine the associations between maternal intake of selenium and selenium status with gestational length and preterm delivery in 72,025 women with singleton live births from the population based, prospective Norwegian Mother, Father and Child Cohort Study (MoBa). A self-reported, semi-quantitative food-frequency questionnaire answered in pregnancy week 22 was used to estimate selenium intake during the first half of pregnancy. Associations were analysed with adjusted linear and cox regressions. Selenium status was assessed in whole blood collected in gestational week 17 (n=2,637). Median dietary selenium intake was 53 (IQR: 44-62) µg/day, supplements provided additionally 50 (30-75) µg/day for supplement-users (n=23,409). Maternal dietary selenium intake was significantly associated with prolonged gestational length (β per SD=0.25, 95% CI=0.07-0.43) and decreased risk for preterm delivery (n=3,618, HR per SD=0.92, 95% CI=0.87-0.98). Neither selenium intake from supplements nor maternal blood selenium status was associated with gestational length or preterm delivery. Hence, this study showed that maternal dietary selenium intake, but not intake of selenium containing supplements, during the first half of pregnancy was significantly associated with decreased risk for preterm delivery. Further investigations, preferably in the form of a large RCT, are needed to elucidate the impact of selenium on pregnancy duration.
In the 2015 review paper ‘Petawatt Class Lasers Worldwide’ a comprehensive overview of the current status of high-power facilities of
was presented. This was largely based on facility specifications, with some description of their uses, for instance in fundamental ultra-high-intensity interactions, secondary source generation, and inertial confinement fusion (ICF). With the 2018 Nobel Prize in Physics being awarded to Professors Donna Strickland and Gerard Mourou for the development of the technique of chirped pulse amplification (CPA), which made these lasers possible, we celebrate by providing a comprehensive update of the current status of ultra-high-power lasers and demonstrate how the technology has developed. We are now in the era of multi-petawatt facilities coming online, with 100 PW lasers being proposed and even under construction. In addition to this there is a pull towards development of industrial and multi-disciplinary applications, which demands much higher repetition rates, delivering high-average powers with higher efficiencies and the use of alternative wavelengths: mid-IR facilities. So apart from a comprehensive update of the current global status, we want to look at what technologies are to be deployed to get to these new regimes, and some of the critical issues facing their development.
Despite its established efficacy, access to internet-delivered CBT (iCBT) remains limited in a number of countries. Translating existing programs and using a minimally monitored model of delivery may facilitate its dissemination across countries.
This randomized control trial aims to evaluate the efficacy of an iCBT transdiagnostic program translated from English to French and offered in Canada using a minimally monitored delivery model for the treatment of anxiety and depression.
Sixty-three French speakers recruited in Canada were randomized to iCBT or a waiting-list. A French translation of an established program, the Wellbeing Course, was offered over 8 weeks using a minimally monitored delivery model. Primary outcome measures were the Generalized Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9), which were obtained pre-treatment, post-treatment and at 3-month follow-up.
Mixed-effects models revealed that participants in the treatment group had significantly lower PHQ-9 and GAD-7 scores post-treatment than controls with small between-groups effect sizes (d = 0.34 and 0.37, respectively). Within-group effect sizes on primary outcome measures were larger in the treatment than control group. Clinical recovery rates on the PHQ-9 and GAD-7 were significantly higher among the treatment group (40 and 56%, respectively) than the controls (13 and 16%, respectively).
The provision of a translated iCBT program using a minimally monitored delivery model may improve patients’ access to treatment of anxiety and depression across countries. This may be an optimal first step in improving access to iCBT before sufficient resources can be secured to implement a wider range of iCBT services.
The aggregation of neurocognitive deficits among the non-psychotic first-degree relatives of adult- and childhood-onset schizophrenia patients suggests that there may be a common etiology for these deficits in childhood- and adult-onset illness. However, there is considerable heterogeneity in the presentation of neurobiological abnormalities, and whether there are differences in the extent of familial transmission for specific domains of cognitive function has not been systematically addressed.
We employed variance components analysis, as implemented in SOLAR-Eclipse, to evaluate the evidence of familial transmission for empirically derived composite scores representing attention, working memory, verbal learning, verbal retention, and memory for faces. We contrast estimates for adult- and childhood-onset schizophrenia families and matched community control pedigrees, and compare our findings to previous reports based on analogous neurocognitive assessments.
We observed varying degrees of familial transmission; attention and working memory yielded comparable, significant estimates for adult-onset and community control pedigrees; verbal learning was significant for childhood-onset and community control pedigrees; and facial memory demonstrated significant familial transmission only for childhood-onset schizophrenia. Model-fitting analyses indicated significant differences in familiality between adult- and childhood-onset schizophrenia for attention, working memory, and verbal learning.
By comprehensively assessing a wide range of neurocognitive domains in adult- and childhood-onset schizophrenia families, we provide additional support for specific neurocognitive domains as schizophrenia endophenotypes. Whereas comparable estimates of familial transmission for certain dimensions of cognitive functioning support a shared etiology of adult- and childhood-onset neurocognitive function, observed differences may be taken as preliminary evidence of partially divergent multifactorial architectures.
This chapter addresses a special category of cases in which an asserted patent is, or has been declared to be, essential to the implementation of a collaboratively developed voluntary consensus standard, and the holder of that patent has agreed to license it to implementers of the standard on terms that are fair, reasonable, and nondiscriminatory (FRAND).This chapter explores how the existence of such a FRAND commitment may affect a patent holder’s entitlement to monetary damages and injunctive relief. In addition to issues of patent law, remedies law, and contracts law, we consider the effect of competition law on this issue.
Patent systems commonly empower courts to order accused or adjudged infringers to refrain from continuing infringing conduct in the future. Some patentees file suit for the primary purpose of obtaining and enforcing an injunction against infringement by a competitor, and even in cases in which the patentee is willing to license an invention to an accused infringer for an agreed price, the indirect monetary value of an injunction against future infringement can dwarf the amount a finder of fact is likely to award as compensation for past infringement. In some of these cases, an injunction, if granted, would impose costs on accused infringers or third parties that go well beyond the more intrinsic value of the patented technology. This chapter explores the theory behind injunctive relief in patent cases, surveys the availability of this remedy in major patent systems, and suggests a general framework for courts to use when deciding whether injunctive relief is appropriate in individual cases.
This chapter addresses two types of monetary remedies for patent infringement: (1) recovery of the patentee’s lost profits and (2) disgorgement of the infringer’s profits. Both remedies make a comparison between what actually happened and a hypothetical “but for” world in which no infringement occurred. But the two remedies have substantially different objectives: Lost profits are intended to compensate the patentee by restoring it to the position it would have occupied absent infringement, while disgorgement may serve other purposes, including deterrence, recapturing wrongful gains, and encouraging ex ante licensing of patented technology. Section 1 addresses several key issues regarding lost profits awards, including the availability and standard of proof, the role of noninfringing alternatives, potential recovery for the sale of related but unpatented goods, whether and how to apportion lost profits awards for complex products, and potential recovery for other infringement-related harms. Section 2 describes the justifications for, and availability of, the disgorgement (accounting) remedy in major patent systems and, additionally, analyzes a number of questions related to calculating such awards. In both sections, recommendations are made and areas for further research are identified.
This chapter discusses the law and policy of monetary awards — including exemplary damages and litigation cost recoveries — that go beyond the compensatory damages to which prevailing parties in patent litigation are normally entitled. Up to treble damages are authorized in the United States for knowing infringement, but attorney fees are awarded only in exceptional cases. The rest of the world tends toward the opposite: Attorney fees are awarded as a matter of course, but punitive damages are generally prohibited as against public policy.This chapter discusses the theory, law, and policy of enhanced damages and attorney fee awards in the United States, Europe, and Asia. While the availability of enhanced damages and fees can bring accused infringers that might otherwise “hold out” to the table, care must also be taken to ensure that it does not discourage productive learning from patents or challenges to overbroad and vague patents. Rather than endorse any single set of doctrinal rules, there is a recommendation for further research into a number of unanswered questions about current and potential future configurations, in order to inform future policymaking.
This chapter describes the current state of, and normative basis for, the law of reasonable royalties among the leading jurisdictions for patent infringement litigation, as well as the principal arguments for and against various practices relating to the calculation of reasonable royalties; and for each of the major issues discussed, the chapter provides one or more recommendations. The chapter’s principal recommendation is that, when applying a “bottom-up” approach to estimating reasonable royalties, courts should replace the Georgia-Pacific factors (and analogous factors used outside the United States) with a smaller list of considerations, specifically (1) calculating the incremental value of the invention and dividing it appropriately between the parties; (2) assessing market evidence, such as comparable licenses; and (3) where feasible and cost justified, using each of these first two considerations as a “check” on the accuracy of the other
A national need is to prepare for and respond to accidental or intentional disasters categorized as chemical, biological, radiological, nuclear, or explosive (CBRNE). These incidents require specific subject-matter expertise, yet have commonalities. We identify 7 core elements comprising CBRNE science that require integration for effective preparedness planning and public health and medical response and recovery. These core elements are (1) basic and clinical sciences, (2) modeling and systems management, (3) planning, (4) response and incident management, (5) recovery and resilience, (6) lessons learned, and (7) continuous improvement. A key feature is the ability of relevant subject matter experts to integrate information into response operations. We propose the CBRNE medical operations science support expert as a professional who (1) understands that CBRNE incidents require an integrated systems approach, (2) understands the key functions and contributions of CBRNE science practitioners, (3) helps direct strategic and tactical CBRNE planning and responses through first-hand experience, and (4) provides advice to senior decision-makers managing response activities. Recognition of both CBRNE science as a distinct competency and the establishment of the CBRNE medical operations science support expert informs the public of the enormous progress made, broadcasts opportunities for new talent, and enhances the sophistication and analytic expertise of senior managers planning for and responding to CBRNE incidents.
Although political scientists have increasingly focused on the role of gender in the policy process and the characteristics of individual lobbyists, little is known about the gender politics of the government relations profession. We extend the study of professional women to the unique political context of Washington, DC, lobbying, an important form of political participation that is understudied in terms of gender. Using data from more than 25,000 individuals registered to lobby the federal government from 2008 to 2015, we show that women account for 37% of the lobbyist population in Washington, that female lobbyists are more likely to work as in-house employees than for contract lobbying firms, and that the largest Washington lobbying firms are strongly biased towards employing men. We add to these findings qualitative data from in-depth interviews with 23 lobbyists to reveal how the professional experiences of women often depend on the idiosyncrasies of lobbying employment and the political nature of their work. We conclude that the underrepresentation of women in the professional lobbying community is an underappreciated problem with broader implications for gender equality in elite political participation.
One generation's experience of childhood maltreatment is associated with that of the next. However, whether this intergenerational transmission is specific to distinct forms of maltreatment and what factors may contribute to its continuity remains unclear. Borderline personality pathology is predicted by childhood maltreatment and characterized by features (e.g., dysregulated emotion, relationship instability, impulsivity, and inconsistent appraisals of others) that may contribute to its propagation. Among 364 older adults and 573 of their adult children (total n = 937), self-reported exposure to distinct forms of childhood maltreatment (i.e., emotional, physical, and sexual abuse, and emotional and physical neglect as assessed by the Childhood Trauma Questionnaire) showed homotypic and heterotypic associations across generations with little evidence that latent factors unique to specific forms of maltreatment show generational continuity. General nonspecific indices of childhood maltreatment showed evidence of intergenerational transmission after accounting for demographic factors and parent socioeconomic status (b = 0.126, p = 9.21 × 10−4). This continuity was partially mediated by parental borderline personality pathology (assessed longitudinally through a variety of measures and sources, indirect effect: b = 0.031, 95% confidence interval [0.003, 0.060]). The intergenerational continuity of childhood maltreatment may largely represent general risk for nonspecific maltreatment that may, in part, be propagated by borderline personality pathology and/or shared risk factors.
Though theory suggests that individual differences in neuroticism (a tendency to experience negative emotions) would be associated with altered functioning of the amygdala (which has been linked with emotionality and emotion dysregulation in childhood, adolescence, and adulthood), results of functional neuroimaging studies have been contradictory and inconclusive. We aimed to clarify the relationship between neuroticism and three hypothesized neural markers derived from functional magnetic resonance imaging during negative emotion face processing: amygdala activation, amygdala habituation, and amygdala-prefrontal connectivity, each of which plays an important role in the experience and regulation of emotions. We used general linear models to examine the relationship between trait neuroticism and the hypothesized neural markers in a large sample of over 500 young adults. Although neuroticism was not significantly associated with magnitude of amygdala activation or amygdala habituation, it was associated with amygdala–ventromedial prefrontal cortex connectivity, which has been implicated in emotion regulation. Results suggest that trait neuroticism may represent a failure in top-down control and regulation of emotional reactions, rather than overactive emotion generation processes, per se. These findings suggest that neuroticism, which has been associated with increased rates of transdiagnostic psychopathology, may represent a failure in the inhibitory neurocircuitry associated with emotion regulation.
