Advances in Post-Resuscitation Care: the Role of Therapeutic Hypothermia
Mild therapeutic hypothermia (32°C-34°C) is the only therapy that improved neurological outcome after cardiac arrest in randomized, controlled trials. It protects the brain after ischemia by reduction of brain metabolism, attenuation of reactive oxygen species formation, inhibition of excitatory amino acid release, attenuation of the immune response during reperfusion and inhibition of apoptosis. Its use is recommended by the American Heart Association and the International Liaison Committee on Resuscitation for unconscious adult patients with spontaneous circulation after out-of-hospital ventricular fibrillation cardiac arrest , 12 to 24 hours following resuscitation. The role of therapeutic hypothermia is uncertain when the initial cardiac rhythm is asystole or pulseless electrical activity, or when the cardiac arrest is primarily due to a noncardiac cause, such as asphyxia or drug overdose. Therefore, in patients with anoxic brain injury after nonventricular fibrillation cardiac arrest, clinicians will need to balance the possible benefit of therapeutic hypothermia with the possible side effects of this therapy. Mild hypothermia is a safe and effective therapy after cardiac arrest, even in hemodynamically compromised patients and in patients undergoing percutaneous coronary intervention. Because the induction of therapeutic hypothermia has become more feasible with the development of simple intravenous cooling techniques and specialized equipment for improved temperature control in the critical care unit, it is expected that therapeutic hypothermia will become more widely used in the management of anoxic neurological injury whatever the presenting cardiac rhythm. Potential side effects have to be kept in mind and treated accordingly
Nitrogen and sulphur management: challenges for organic sources in temperate agricultural systems
A current global trend towards intensification or specialization of agricultural enterprises has been accompanied by increasing public awareness of associated environmental consequences. Air and water pollution from losses of nutrients, such as nitrogen (N) and sulphur (S), are a major concern. Governments have initiated extensive regulatory frameworks, including various land use policies, in an attempt to control or reduce the losses. This paper presents an overview of critical input and loss processes affecting N and S for temperate climates, and provides some background to the discussion in subsequent papers evaluating specific farming systems. Management effects on potential gaseous and leaching losses, the lack of synchrony between supply of nutrients and plant demand, and options for optimizing the efficiency of N and S use are reviewed. Integration of inorganic and organic fertilizer inputs and the equitable re-distribution of nutrients from manure are discussed. The paper concludes by highlighting a need for innovative research that is also targeted to practical approaches for reducing N and S losses, and improving the overall synchrony between supply and demand
Social values priorities and orientation towards individualism and collectivism of Greek university students
The study aimed to explore the value priorities of Greek young adults and their orientation towards individualism and collectivism and to investigate for possible relationships between value types and individualism and collectivism. Greek undergraduate students (n = 484) completed the Social Values Survey, the Aucklands Individualism and Collectivism Scale and a form of demographic information. Benevolence, self-direction and hedonism were found to be the most highly rated value types for both males and females. In the case of individualism and collectivism participants scored higher on collectivism. Males and science and technology students scored higher on value types regarding openness to change and self-enhancement. Females and social and humanities students scored higher on conservation and self-transcendence value types. Religiosity was associated to collectivism and to value types regarding conservation and self-transcendence. Regression analysis revealed a direct association between individualism and openness to change and self-enhancement. Collectivism was found to be associated with conservation and self-transcendence. © 2016 Taylor & Francis
Improving the School Learning Environment to Reduce Bullying: An Experimental Study
A framework based on research on bullying and on educational effectiveness was offered to schools to assist them in developing strategies and actions to improve their learning environment, their policy for teaching, and their evaluation mechanisms in order to reduce bullying. At the beginning and end of the intervention, the Revised Olweus Bully/Victim Questionnaire and a teacher questionnaire measuring three school factors (school policy for teaching, school learning environment, and school evaluation) were administered to the experimental and control groups. This experimental study reveals that the intervention had both a direct impact on the reduction of bullying and an indirect impact through improving the school factors. Implications for research into supporting schools to reduce bullying are given. © 2013 © 2013 Scandinavian Journal of Educational Research
