EVAR FOR ABDOMINAL AORTIC ANEURYSM IN ELDERLY PATIENTS,AND THE BIOETHICAL ISSUES THAT COULD GENERATE

Open repair is likely to be more cost-effective than EVAR on average in patients considered fit for open surgery. EVAR is likely to be more cost- effective than open repair for a subgroup of patients at higher risk of operative mortality. These results are based on extrapolation of mid-term results of clinical trials. But how does that affect on patients who are older than 80 years. Late survival depends very much on the patient＇s age at the time of surgery. The life expectancy in this group of patients who undergo successful Abdominal Aortic Aneurysm （AAA） open repair or EVAR is not as good as that of the age-matched general population. At this age, life expectancy is six years or more over patients who are older than 85 years, life expectancy is just five years. On the other hand, annual/one year risk of rupture in patients with AAA diameter six to seven cm is 10%-20%. At the same time, total cost of endograft implantation is at least 10,000 euro per patient, which is still extremely expensive for many countries in transition. Regarding all these facts, some countries （in transition） are forced to reassess ethical point of endovascular treatment. Simplified they haven＇t enough endografs for all patients. Vascular surgeon in this situation has need to decide how, when and who needs by priority this expensive graft. Of course, this is not medical question, but for sure question that encumbers vascular surgeons from countries in transition. Should we consider octogenarians as the first group of patient who will endure this problem？ How to decide who needs endograft as priority and who does not？ Finally, who is better candidate for endovascular, open surgical or medicament treatment from financial point of view？ These are just some of the questions, which are still open and encumber many vascular surgeons from countries with poorer healthcare system.     

Aggressive,Delinquent, and Violent Outcomes of School Bullying: Do Family and Individual Factors Have a Protective Function?

Bullying perpetration at school is a long-term predictor of aggression, delinquency, and violence. Most research concentrates on risk factors for such developments, whereas protective factors have been rarely addressed. Therefore, the present study investigates potentially protective effects of family and child characteristics in a prospective longitudinal design. The sample contained 519 youngsters (253 boys and 266 girls) from the Erlangen-Nuremberg Development and Prevention Study. Bullying perpetration was measured at age 9.0 years, mothers’ and children's reports on family and individual characteristics were collected at age 10.6, and outcomes in self-reported aggressive/violent offending and mother-reported aggressive and delinquent behavior were collected at age 13.7. Hierarchical regression analyses revealed main effects and interactions. The latter suggest buffering protective effects of consistent discipline in parenting and children's intelligence, positive attitude to school, prosocial behavior skills, low hyperactivity/inattention, and an anxious/depressive mood. The findings varied across the two outcome measures and with regard to gender. Implications for further research and prevention practice are discussed.     

Parallel Paths A Comparison of CSR Firms and Social Enterprises

Corporate social responsibility （CSR） is the incorporation of environmental and social responsibilities into the business activity, in line with the economic responsibility that firms have traditionally focused on. The social entrepreneur is a type of entrepreneur who seeks to resolve a social or environmental problem through the application of a business model, motivated by the aim of helping others and pursuing positive social change. A key aspect of social entrepreneurship （SE） is therefore the creation of social wealth. Both concepts pursue positive social change, but unlike social entrepreneurs, the objective of a responsible firm is not to solve social issues created by others, rather to understand and limit the social and environmental impacts of their profit-generating activities. In recent decades, research on CSR has grown considerably, whereas SE has only begun to receive serious academic attention quite recently. Crucially, few studies have tried to link and differentiate the two areas. Due to the increasing interest in both concepts nowadays, the need to clarify the similarities and differences between them is greater than ever, and is the principal aim of this work.     

Formalizing China��s armed police: the 2009 PAP Law

While the People??s Armed Police (PAP) has existed in China for over 26 years, the force??s operations, powers and duties have never been formally stipulated. On August 27, 2009, the People??s Armed Police Law was passed by the National People??s Congress. The PAP Law, which contains seven chapters and 38 articles, covers the main areas of the tasks and responsibility, duties and power, safeguard measures, discipline and supervision, and legal responsibilities of the force. The implementation of the PAP Law represents a benchmark development in the history of the Chinese policing. It not only signals official recognition of the need to enhance the legitimacy of China??s social control apparatus, but also maps onto a larger developing trend of progressive legalization of Chinese order today. Although the law provides a legal basis for the existence and functions of a force that plays a critical role in China??s security and stability today, some issues about the boundaries of power and procedures of operation for the PAP remain unaddressed. To what extent that this law will improve the legitimacy and subsequently strengthen the performance of the PAP force is an open question.     

Rapid analysis of caffeine in "smart drugs" and "energy drinks" by microemulsion electrokinetic chromatography (MEEKC)

A novel method based on microemulsion electrokinetic chromatography (MEEKC) with diode array detection (DAD) for rapid determination of caffeine in commercial and clandestine stimulants, known as "energy drinks" and "smart drugs", is described. Separations were carried out in 50 cm × 50 μm (ID) uncoated fused silica capillaries. The optimized buffer electrolyte was composed of 8.85 mM sodium tetraborate pH 9.5, SDS 3.3% (w/v), n-hexane 1.5% (v/v) and 1-butanol 6.6% (v/v). Separations were performed at a voltage of 20 kV. Sample injection conditions were 0.5 psi, 3 s. Diprofilline was used as internal standard. The determination of the analytes was based on the UV signal recorded at 275 nm, corresponding to the maximum wavelength of absorbance of caffeine, whereas peak identification and purity check was performed on the basis of the acquisition of UV radiation between 200 and 400 nm wavelengths. Under the described conditions, the separation of the compounds was achieved in 6 min without any interference from the matrix. Linearity was assessed within a caffeine concentration range from 5 to 100 μg/mL. The intra-day and inter-day precision values were below 0.37% for migration times and below 9.86% for peak areas. The present MEEKC method was successfully applied to the direct determination of caffeine in smart drugs and energy drinks.     

Research Foundations of Greenbook Interventions to Address the Co‐Occurrence of Child Maltreatment and Adult Domestic Violence

Twenty years ago the National Council of Juvenile and Family Court Judges published Effective Intervention in Domestic Violence and Child Maltreatment: Guidelines for Policy and Practice, which became known as the Greenbook because of its green cover. This article presents the social science research leading up to the Greenbook and the 20 years beyond the publication of this seminal document, including examination of the effect of co‐occurrence of child maltreatment and exposure to domestic violence on child outcomes, the interventions for families to improve the safety of both child and adult victims, and future directions for research.     

Accuracy of four dental age estimation methodologies in Brazilian and Croatian children

ObjectiveTo compare and analyse the accuracy of four age estimation methods using the mineralisation stages of the permanent teeth (Cameriere et al. [16] [CAM], Liliequist and Lundberg [LLH] and Nolla without third molars [NOL7] or with them [NOL8]) in a mixed population of Brazilians and a homogeneous population of Croatians.MethodsOrthopantomograms of 930 Brazilians (366 males and 564 females) and 924 Croatians (365 males and 556 females) aged between 8 and 14.99 years were analysed using the CAM, LLH, NOL7 and NOL8 age estimation methodologies.ResultsLLH presented the best absolute differences (ADs) among both populations without sex stratification, while CAM presented the worst results. In addition, the mean differences revealed underestimations, except when the LLH and NOL7 methods were used for the Brazilians. When the sample was stratified by sex, the best AD values were found with NOL7 (0.80) for the Brazilians and with LLH (0.98) for the Croatians. When the sample was stratified by sex and age, CAM presented high accuracy at the early ages, and LLH presented high accuracy at the older ages. The results obtained with the Nolla methods (NOL7 and NOL8) were mostly similar, but NOL7 yielded slightly better results.ConclusionsThe values for the Brazilians and the Croatians were relatively similar, and the techniques were properly applied in both population samples. The best method for evaluating both countries was LLH, followed by NOL7, NOL8 and CAM.     

Do Work-Family Conflict and Resiliency Mediate Police Stress and Burnout: a Study of State Police Officers

Occupational stress and burnout have long been recognized as common hazards among police officers. The present study examines whether demographic characteristics and assignment affect police officers’ work-family conflict (WFC), resiliency, stress and burnout, and whether WFC and resiliency mediate the stress and burnout of police officers. The data were collected from a Mid-Atlantic state police agency in the United States of America through a web-based survey. Regression results revealed that minority officers tended to have lower levels of WFC and burnout and better educated officers reported lower degrees of WFC and stress. WFC was positively related to stress and burnout, while resilience was inversely linked to stress and burnout. The effects of race and education disappeared when WFC and resiliency entered the regression, suggesting that their impact was largely mediated by WFC and resiliency. Lastly, stress was found to be positively associated with burnout. Implications for research and policy are discussed.
