Democratic and participatory citizenship: Youth action for sustainability in Australia

Purpose – The purpose of this paper is to provide a critical analysis of recent examples of action competence among young people engaged in democratic participatory action in sustainability programs in Australia. It explores examples of priorities identified for citizen action, the forms this action takes and the ways that democratic participation can achieve positive outcomes for future sustainability. It suggests multiple ways for developing action competence that provides further opportunities for authentic and engaging citizen action for youth connected to school- and community-based learning, in new and powerful ways. Design/methodology/approach – This conceptual paper examines international literature on the theory of “action competence,” its significance for education for sustainability (EfS) and the ways it can inform education for young people’s democratic participatory citizenship and civic engagement. It analyses examples of the development of action competency among young people in Australia, including the problems and priorities identified for citizen action, the forms this action takes and how it can achieve positive outcomes for sustainability. Following this analysis, the paper suggests multiple ways for developing action competence in EfS in schools and communities in new and powerful ways. Findings – Developing EfS to increase democratic and participatory action among young citizens is now widely regarded as an urgent education priority. There are growing exemplars of school and community organizations’ involvement in developing EfS learning and teaching to increase participatory citizenship. Young people are being empowered to develop a greater sense of agency through involvement in programs that develop action competence with a focus on sustainability in and out of school. New forms of participation include student action teams and peer collaboration among youth who are marshaling social media and direction action to achieve change. Originality/value – It contributes to the literature on multiple ways for developing action competence in EfS.

Maallikon suorittama defibrillaatio sydänpysähdyspotilaan hoitoketjussa

Sudden cardiac arrest (CA) is one of the leading causes of death in Europe. It has been estimated that about 40 % of CA victims have ventricular fibrillation (VF) at the time of the first heart rhythm analysis. The treatment for VF is immediate cardiopulmonary resuscitation (CPR) and rapid defibrillation. The automated external defibrillator (AED) and the concept of public access defibrillation (PAD) may be a key to shortening defibrillation delays. Recent studies have shown that PAD programs are associated with high survival rates from VF when devices have been placed in certain risk sites and used by trained laypersons. Today many public places are equipped with AEDs. The purpose of this study was to find new ways of utilizing layperson defibrillation and promote the concept of public access defibrillation (PAD). The study explored the use of AEDs by non-medical first responders in Finland and cabin crew on board a commercial aircraft. A simulated study was performed to explore the role of dispatcher assistance in layperson CPR and defibrillation. A 15-year follow-up study of 59 one-year survivors after successful out-of-hospital resuscitation was performed to evaluate the long-term quality of life of the CA patients. Although there are many AEDs in use by non-medical first responders in Finland, the results of the study showed that there are large variations between individual first response units. This is considered to be caused by the lack of national standards and regulations that would define a full integration of first-responder programmes into the Emergency Medical Services system. The goal of rapid defibrillation in five minutes after the onset of CA is difficult to achieve in Finland due to sparse population and long distances. Local PAD programs may shorten the defibrillation delays. Dispatcher assistance in defibrillation by a layperson not trained to use an AED seems feasible and does not compromise the performance of CPR. In a simulated study, the quality of mouth-to-mouth ventilation performed by laypersons was found to be better after CPR training compared with performance with dispatcher assistance before training. Training was not found to have an influence on the quality of compressions or defibrillation compared with dispatcher assistance of untrained laypersons. The target groups for CPR and defibrillation training need further evaluation. The placements of the AEDs in public areas should be known by the emergency response center and the location should be marked with an international sign. The finding that once a good neurological outcome after CA is achieved, it can be maintained for more than 10 years, encourages further efforts to improve the survival of CA patients.

Current Care Guidelines for Cardiopulmonary Resuscitation : Implementation, skills and attitudes

Background: The national resuscitation guidelines were published in Finland in 2002 and are based on international guidelines published in 2000. The main goal of the national guidelines, available on the Internet free of charge, is early defibrillation by nurses in an institutional setting. Aim: To study possible changes in cardiopulmonary resuscitation (CPR) practices, especially concerning early defibrillation, nurses and students attitudes of guideline implementation and nurses and students ability to implement the guideline recommendations in clinical practices after publication of the Current Care (CC) guidelines for CPR 2002. Material and methods: CPR practices in Finnish health centres; especially concerning rapid defibrillation programmes, as well as the implementation of CC guidelines for CPR was studied in a mail survey to chief physicians of every health centre in Finland (Study I). The CPR skills using an automated external defibrillator (AED) were compared in a study including Objective stuctured clinical examination (OSCE) of resuscitation skills of nurses and nursing students in Finnish and Swedish hospital and institution (Studies II, III). Attitudes towards CPR-D and CPR guidelines among medical and nursing students and secondary hospital nurses were studied in surveys (Studies IV, V). The nurses receiving different CPR training were compared in a randomized trial including OSCE of CPR skills of nurses in Finnish Hospital (Study VI). Results: Two years after the publication, 40.7% of Finnish health centres used national resuscitation guidelines. The proportion of health centres having at least one AED (66%) and principle of nurse-performed defibrillation without the presence of a physician (42%) had increased. The CPR-D training was estimated to be insufficient regarding basic life support and advanced life support in the majority of health centres (Study I). CPR-D skills of nurses and nursing students in two specific Swedish and Finnish hospitals and institutions (Study II and III) were generally inadequate. The nurses performed better than the students and the Swedish nurses surpassed the Finnish ones. Geriatric nurses receiving traditional CPR-D training performed better than those receiving an Internet-based course but both groups failed to defibrillate within 60 s. Thus, the performance was not satisfactory even two weeks after traditional training (Study VI). Unlike the medical students, the nursing students did not feel competent to perform procedures recommended in the cardiopulmonary resuscitation guidelines including the defibrillation. However, the majority of nursing students felt confident about their ability to perform basic life support. The perceived ability to defibrillate correlated significantly with a positive attitude towards nurse-performed defibrillation and negatively with fear of damaging the patient s heart by defibrillation (Study IV). After the educational intervention, the nurses found their level of CPR-D capability more sufficient than before and felt more confident about their ability to perform defibrillation themselves. A negative attitude toward defibrillation correlated with perceived negative organisational attitudes toward cardiopulmonary resuscitation guidelines. After CPR-D education in the hospital, the majority (64%) of nurses hesitated to perform defibrillation because of anxiety and 27 % hesitated because of fear of injuring the patient. Also a negative personal attitude towards guidelines increased markedly after education (Study V). Conclusions: Although a significant change had occurred in resuscitation practices in primary health care after publication of national cardiopulmonary resuscitation guidelines the participants CPR-D skills were not adequate according to the CPR guidelines. The current way of teaching is unlikely to result in participants being able to perform adequate and rapid CPR-D. More information and more frequent training are needed to diminish anxiety concerning defibrillation. Negative beliefs and attitudes toward defibrillation affect the nursing students and nurses attitudes toward cardiopulmonary resuscitation guidelines. CPR-D education increased the participants self-confidence concerning CPR-D skills but it did not reduce their anxiety. AEDs have replaced the manual defibrillators in most institutions, but in spite of the modern devices the anxiety still exists. Basic education does not provide nursing students with adequate CPR-D skills. Thus, frequent training in the workplace has vital importance. This multi-professional program supported by the administration might provide better CPR-D skills. Distance learning alone cannot substitute for traditional small-group learning, tutored hands-on training is needed to learn practical CPR-D skills. Standardized testing would probably help controlling the quality of learning. Training of group-working skills might improve CPR performance.

New signal processing algorithms for automated external defibrillators

[ES]La fibrilación ventricular (VF) es el primer ritmo registrado en el 40\,\% de las muertes súbitas por paro cardiorrespiratorio extrahospitalario (PCRE). El único tratamiento eficaz para la FV es la desfibrilación mediante una descarga eléctrica. Fuera del hospital, la descarga se administra mediante un desfibrilador externo automático (DEA), que previamente analiza el electrocardiograma (ECG) del paciente y comprueba si presenta un ritmo desfibrilable. La supervivencia en un caso de PCRE depende fundamentalmente de dos factores: la desfibrilación temprana y la resucitación cardiopulmonar (RCP) temprana, que prolonga la FV y por lo tanto la oportunidad de desfibrilación. Para un correcto análisis del ritmo cardiaco es necesario interrumpir la RCP, ya que, debido a las compresiones torácicas, la RCP introduce artefactos en el ECG. Desafortunadamente, la interrupción de la RCP afecta negativamente al éxito en la desfibrilación. En 2003 se aprobó el uso del DEA en pacientes entre 1 y 8 años. Los DEA, que originalmente se diseñaron para pacientes adultos, deben discriminar de forma precisa las arritmias pediátricas para que su uso en niños sea seguro. Varios DEAs se han adaptado para uso pediátrico, bien demostrando la precisión de los algoritmos para adultos con arritmias pediátricas, o bien mediante algoritmos específicos para arritmias pediátricas. Esta tesis presenta un nuevo algoritmo DEA diseñado conjuntamente para pacientes adultos y pediátricos. El algoritmo se ha probado exhaustivamente en bases de datos acordes a los requisitos de la American Heart Association (AHA), y en registros de resucitación con y sin artefacto RCP. El trabajo comenzó con una larga fase experimental en la que se recopilaron y clasificaron retrospectivamente un total de 1090 ritmos pediátricos. Además, se revisó una base de arritmias de adultos y se añadieron 928 nuevos ritmos de adultos. La base de datos final contiene 2782 registros, 1270 se usaron para diseñar el algoritmo y 1512 para validarlo. A continuación, se diseñó un nuevo algoritmo DEA compuesto de cuatro subalgoritmos. Estos subalgoritmos están basados en un conjunto de nuevos parámetros para la detección de arritmias, calculados en diversos dominios de la señal, como el tiempo, la frecuencia, la pendiente o la función de autocorrelación. El algoritmo cumple las exigencias de la AHA para la detección de ritmos desfibrilables y no-desfibrilables tanto en pacientes adultos como en pediátricos. El trabajo concluyó con el análisis del comportamiento del algoritmo con episodios reales de resucitación. En los ritmos que no contenían artefacto RCP se cumplieron las exigencias de la AHA. Posteriormente, se estudió la precisión del algoritmo durante las compresiones torácicas, antes y después de filtrar el artefacto RCP. Para suprimir el artefacto se utilizó un nuevo método desarrollado a lo largo de la tesis. Los ritmos desfibrilables se detectaron de forma precisa tras el filtrado, los no-desfibrilables sin embargo no.

Folic acid use and major congenital malformations in offspring of women with epilepsy: a prospective study from the UK Epilepsy and Pregnancy Register

Objective: In the general population, folic acid supplementation during pregnancy has been demonstrated to reduce the frequency of neural tube defects (NTDs) and other major congenital malformations (MCMs). It is recommended that women with epilepsy contemplating pregnancy take supplemental folic acid because of the known antifolate effect of some antiepileptic drugs (AEDs). Here the aim was to determine the effectiveness of this practice.

Malformation risks of antiepileptic drugs in pregnancy: a prospective study from the UK Epilepsy and Pregnancy Register

Objective: To assess the relative risk of major congenital malformation (MCM) from in utero exposure to antiepileptic drug (AEDs).

A simple bioanalytical method for the quantification of antiepileptic drugs in dried blood spots

An increasing number of publications on the dried blood spot (DBS) sampling approach for the quantification of drugs and metabolites have been spurred on by the inherent advantages of this sampling technique. In the present research, a selective and sensitive high-performance liquid chromatography method for the concurrent determination of multiple antiepileptic drugs (AEDs) [levetiracetam (LVT), lamotrigine (LTG), phenobarbital (PHB)], carbamazepine (CBZ) and its active metabolite carbamazepine-10,11 epoxide (CBZE)] in a single DBS has been developed and validated. Whole blood was spotted onto Guthrie cards and dried. Using a standard punch (6. mm diameter), a circular disc was punched from the card and extracted with methanol: acetonitrile (3:1, v/v) containing hexobarbital (Internal Standard) and sonicated prior to evaporation. The extract was then dissolved in water and vortex mixed before undergoing solid phase extraction using HLB cartridges. Chromatographic separation of the AEDs was achieved using Waters XBridge™ C18 column with a gradient system. The developed method was linear over the concentration ranges studied with r=0.995 for all compounds. The lower limits of quantification (LLOQs) were 2, 1, 2, 0.5 and 1. µg/mL for LVT, LTG, PHB, CBZE and CBZ, respectively. Accuracy (%RE) and precision (%CV) values for within and between day were

Adherence to antiepileptic medicines in children: A multiple-methods assessment involving dried blood spot sampling

Purpose: To evaluate adherence to prescribed antiepileptic drugs (AEDs) in children with epilepsy using a combination of adherence-assessment methods.
Methods: A total of 100 children with epilepsy (=17 years old) were recruited. Medication adherence was determined via parental and child self-reporting (=9 years old), medication refill data from general practitioner (GP) prescribing records, and via AED concentrations in dried blood spot (DBS) samples obtained from children at the clinic and via self- or parental-led sampling in children's own homes. The latter were assessed using population pharmacokinetic modeling. Patients were deemed nonadherent if any of these measures were indicative of nonadherence with the prescribed treatment. In addition, beliefs about medicines, parental confidence in seizure management, and the presence of depressed mood in parents were evaluated to examine their association with nonadherence in the participating children.
Key Findings: The overall rate of nonadherence in children with epilepsy was 33%. Logistic regression analysis indicated that children with generalized epilepsy (vs. focal epilepsy) were more likely (odds ratio [OR] 4.7, 95% confidence interval [CI] 1.37-15.81) to be classified as nonadherent as were children whose parents have depressed mood (OR 3.6, 95% CI 1.16-11.41).
Significance: This is the first study to apply the novel methodology of determining adherence via AED concentrations in clinic and home DBS samples. The present findings show that the latter, with further development, could be a useful approach to adherence assessment when combined with other measures including parent and child self-reporting. Seizure type and parental depressed mood were strongly predictive of nonadherence. © 2013 International League Against Epilepsy.

Characterization of the effects of antiepileptic drugs on bone metabolism: in vitro studies with human osteoblastic and osteoclastic cells

Bone is constantly being molded and shaped by the action of osteoclasts and osteoblasts. A proper equilibrium between both cell types metabolic activities is required to ensure an adequate skeletal tissue structure, and it involves resorption of old bone and formation of new bone tissue. It is reported that treatment with antiepileptic drugs (AEDs) can elicit alterations in skeletal structure, in particular in bone mineral density. Nevertheless, the knowledge regarding the effects of AEDs on bone cells are still scarce. In this context, the aim of this study was to investigate the effects of five different AEDs on human osteoclastic, osteoblastic and co-cultured cells. Osteoclastic cell cultures were established from precursor cells isolated from human peripheral blood and were characterized for tartrate-resistant acid phosphatase (TRAP) activity, number of TRAP+ multinucleated cells, presence of cells with actin rings and expressing vitronectin and calcitonin receptors and apoptosis rate. Also, the involvement of several signaling pathways on the cellular response was addressed. Osteoblastic cell cultures were obtained from femur heads of patients (25-45 years old) undergoing orthopaedic surgery procedures and were then studied for cellular proliferation/viability, ALP activity, histochemical staining of ALP and apoptosis rate. Also the expression of osteoblast-related genes and the involvement of some osteoblastogenesis-related signalling pathways on cellular response were addressed. For co-cultured cells, osteoblastic cells were firstly seeded and cultured. After that, PBMC were added to the osteoblastic cells and co-cultures were evaluated using the same osteoclast and osteoblast parameters mentioned above for the corresponding isolated cell. Cell-cultures were maintained in the absence (control) or in the presence of different AEDs (carbamazepine, gabapentin, lamotrigine, topiramate and valproic acid). All the tested drugs were able to affect osteoclastic and osteoblastic cells development, although with different profiles on their osteoclastogenic and osteoblastogenic modulation properties. Globally, the tendency was to inhibit the process. Furthermore, the signaling pathways involved in the process also seemed to be differently affected by the AEDs, suggesting that the different drugs may affect osteoclastogenesis and/or osteoblastogenesis through different mechanisms. In conclusion, the present study showed that the different AEDs had the ability to directly and indirectly modulate bone cells differentiation, shedding new light towards a better understanding of how these drugs can affect bone tissue.

Oral pregabalin as an add-on treatment for status epilepticus.

Oral antiepileptic drugs (AEDs) represent possible add-on options in refractory status epilepticus (SE). In this setting, pregabalin (PGB) has not been reported before. Over the last 42 months, we identified 11 SE episodes (10 patients) treated with PGB in our hospital. Its use was prompted by the favorable pharmacokinetic profile, devoid of drug-drug interactions. The patients mostly had refractory, partial SE. Only two patients were managed in the intensive care unit (ICU). We found a definite electroclinical response in 5 of 11, already evident 24 h after PGB introduction, and a possible response (concomitantly with other AEDs) in 3 of 11 of the episodes; 3/11 did not respond. The treatment was well tolerated. Partial SE appeared to better respond than generalized convulsive SE. PGB appears to be an interesting option as add-on treatment in refractory partial SE.

Clinical experience of clobazam as add-on treatment in a cohort of adults with epilepsy

Objective: Epilepsy is a common neurologic disorder affecting 1% of the world population with one-third of these patients failing to have seizure control for more than one year. Clobazam is a long-acting benzodiazepine used worldwide for the treatment of epilepsy. This antiepileptic drug has demonstrated great clinical benefits with mild side effects. The objective of this study was to better understand the efficacy of clobazam treatment on adult patients with refractory epilepsy. Design: A retrospective review of 44 adult patients with diagnosis of epilepsy that were seen at our Epilepsy Clinic between January 2014 and May 2015. Setting: An outpatient epilepsy clinic at the Hospital Universitario Fundación Santa Fe de Bogota, Colombia. Participants: 44 adult patients with diagnosis of epilepsy. Measurements: Seizure frequency, adverse effects and the use of concomitant AEDs were reviewed in each of the patient´s clinical charts. Results: The responder rate of patients with clobazam was 52% at 3 months, 50% at 6 months and 55% at 12 month. Seizure freedom rates at 3, 6 and 12 months were 18%, 25% and 25% respectively. Clobazam related adverse events occurred only in four patients (9%) at the end of the twelve months with somnolence being the most common. Conclusion: These findings suggest that clobazam treatment in adult patients with focal or generalized epilepsy is effective and safe. Its use should be considered early when first-line agents fail to provide seizure control.

Espaços de pobreza e mobilidade urbana: os deslocamentos da população de baixa renda em Natal/RN

This dissertation is an attempt to understand how families with an income of up to three minimum wages and living in different Areas of Demographic Expansion (AEDs) of Natal municipality specifically in the districts of Igapó and Salinas (North Administrative Zone of the city), Ponta Negra (South Administrative Zone), Santos Reis, Praia do Meio, Areia Preta and Mãe Luíza (East Administrative Zone) and Felipe Camarão (West Administrative Zone) solve their problems of urban mobility. It is, therefore, a reflection upon the mobility needs of poor urban households as expressed in terms of origin-destiny displacements for specific movements (house-work, house-school, house-shopping, house-healthcare and house-leisure), all of which being analyzed within the relationship between public transportation and poverty spaces of the city. In order to develop the study, theoretical aspects and themes related to the production of the urban space, to social and spatial segregation, to urban mobility and to transportation were confronted with the collected data referring to the urban population previously selected. One of the research main findings is the crucial role mobility plays in the social differentiation of such people living in Natal and that any policy for the improvement of their living conditions must take mobility issues into account

Determination of anticonvulsants in human plasma using SPME in a heated interface coupled online to liquid chromatography (SPME-LC)

A simple and sensitive method using solid phase microextraction (SPME) and liquid chromatography (LC) with heated online desorption (SPME-LC) was developed and validated to analyze anticonvulsants (AEDs) in human plasma samples. A heated lab-made interface chamber was used in the desorption procedure, which allowed the transference of the whole extracted sample. The SPME conditions were optimized by applying an experimental design. Important factors are discussed such as fiber coating types, pH, extraction time and desorption conditions. The drugs were analyzed by LC, using a C18 column (150 mm 4.6 mm 5 mm); and 50 mmol L1 , pH ¼ 5.50 ammonium acetate buffer : acetonitrile : methanol (55 : 22 : 23 v/v) as the mobile phase with a flow rate of 0.8 mL min1 . The suggested method presented precision (intra-assay and inter-assay), linearity and limit of quantification (LOQ) all adequate for the therapeutic drug monitoring (TDM) of AEDs in plasma.

Antiepileptic drugs and pregnancy. Population based pharmaco-epidemiological study on prescription patterns, pregnancy outcome and foetal health

Aims of the study: To assess the prevalence of Antiepileptic Drug (AED) exposure in pregnant women with or without epilepsy and the comparative risk of terminations of pregnancy (TOPs), spontaneous abortions, stillbirth, major congenital malformations (MCMs) and foetal growth retardation (FGR) following intrauterine AED exposure in the Emilia Romagna region (RER), Northern Italy (4 million inhabitants). Methods: Data were obtained from official regional registries: Certificate of Delivery Assistance, Hospital Discharge Card, reimbursed prescription databases and Registry of Congenital Malformations. We identified all the deliveries, hospitalized abortions and MCMs occurred between January 2009 and December 2011. Results: We identified 145,243 pregnancies: 111,284 deliveries (112,845 live births and 279 stillbirths), 16408 spontaneous abortions and 17551 TOPs. Six hundred and eleven pregnancies (0.42% 95% Cl: 0.39-0.46) were exposed to AEDs. Twenty-one per cent of pregnancies ended in TOP in the AED group vs 12% in the non-exposed (OR:2.24; CI 1.41-3.56). The rate of spontaneous abortions and stillbirth was comparable in the two groups. Three hundred fifty-three babies (0.31%, 95% CI: 0.28-0.35) were exposed to AEDs during the first trimester. The rate of MCMs was 2.3% in the AED group (2.2% in babies exposed to monotherapy and 3.1% in babies exposed to polytherapy) vs 2.0% in the non-exposed. The risk of FGR was 12.7 % in the exposed group compared to 10% in the non-exposed. Discussion and Conclusion: The prevalence of AED exposure in pregnancy in the RER was 0.42%. The rate of MCMs in children exposed to AEDs in utero was almost superimposable to the one of the non-exposed, however polytherapy carried a slightly increased risk . The rate of TOPs was significantly higher in the exposed women. Further studies are needed to clarify whether this high rate reflects a higher rate of MCMs detected prenatally or other more elusive reasons.
