The European Union and global security: is the EU becoming the indispensable partner? EU Centre Singapore Background Brief No. 11, April 2014

The European Union has developed new capacity as a security actor in third countries, in particular in the area of crisis management. Over the past two decades the EU has deployed numerous missions, both of a civilian and military nature. Moreover the EU has defined its ability to intervene all along the ‘crisis cycle’, (from prevention to mediation, from peace-keeping to post-conflict reconstruction) and using all tools at its disposal (taking a ‘comprehensive approach’). However the EU is still not perceived as a major security provider globally and interventions remain limited to some geographic areas, mostly in its neighbourhood and Africa, with just a few examples further afield. The EU also tends to avoid taking direct action and seems to prefer partnership arrangements with other players. How can we explain the growing activism and number of EU’s intervention with the low impact and lack of visibility? Can we expect the EU to become more active in the future, taking on more responsibility and leading roles in addressing conflict situations? This paper will argue that the main reason for the EU’s hesitant role in crisis management is to be found in the weak decision-making provisions for EU’s security interventions, as one of the few policy areas still subject to consensus amongst 28 European Union Member States. Lack of a clearer delegation of competence or stronger coordination structures is closely linked to low legitimacy for the EU to take more robust action as a security actor. In order to overcome this legitimacy problem, and in order to facilitate consensus amongst Member States, the EU thus privileges partnership arrangements with other actors who can provide legitimacy and know-how, such as the UN or the African Union. As there is no political desire in the EU for tighter decision-making in this area, we can expect that the EU will continue to play a supporting rather than leading role in crisis management, becoming the partner of choice as it deepens its experience. However this does not mean that the EU is playing just a secondary role in the wider area of security, in particular when looking at nontraditional security. Looking at the role of the EU in Asia, where the EU has deployed just two missions, this paper will offer a broader assessment of the EU as a partner in the area of security taking into account different types of actions. The paper will argue that in order to strengthen cooperation with Asian partners in the area of crisis management, the EU will need to define better what it is able to offer, present its actions as part of an overall strategy rather than ad-hoc and piecemeal, and enter into partnership arrangements with different players in the region.

Satisfação profissional dos enfermeiros especialistas em enfermagem de reabilitação

Introdução: Portugal enfrenta, actualmente, um período de mudanças profundas nos seus pilares sociais, económicos e organizacionais, sendo o sector da saúde um dois envoltos neste processo de mudança, o qual provoca, inevitavelmente, stress, emoções e ajustamentos de vária ordem. A avaliação da satisfação dos profissionais é assim um fator chave na mensuração dos efeitos destas alterações, daí que o objetivo deste estudo seja conhecer a satisfação profissional dos enfermeiros especialistas de Reabilitação, e seus determinantes de contexto pessoal, profissional e organizacional. Método: Realizou-se um estudo transversal, descritivo-correlacional, de natureza quantitativa, no qual participaram 141 Enfermeiros, Especialistas em Enfermagem de Reabilitação, em funções em instituições públicas e privadas na zona centro do País, na sua maioria do sexo feminino (58.87%) e com uma média de idades de 40.43 anos (Dp=7.49 anos). Para a mensuração das variáveis recorreu-se a uma ficha sociodemográfica e profissional, Escala de Avaliação da Satisfação no Trabalho (EASTEnf) e Escala de Empenhamento Atitudinal, ambas validadas para a população portuguesa. Resultados: Constatou-se que a maioria dos especialistas em Enfermagem de Reabilitação apresentam um nível regular de satisfação (70,92%). Os resultados obtidos evidenciam a existência de um efeito significativo das variáveis género, estado civil, experiência profissional, perfil de cuidados prestados, tipo de horário, vínculo laboral e local de trabalho, sobre o nível de satisfação dos enfermeiros. Na generalidade, são os enfermeiros do género feminino, casados, com menor experiência profissional, que prestam de cuidados especializados, que exercem funções em regime de horário fixo, que integram os quadros da instituição onde desempenham funções e que exercem a sua profissão no sector privado, aqueles que evidenciam, em algumas das dimensões da escala de avaliação da satisfação com o trabalho, níveis de satisfação profissional mais elevados. Por outro lado, constatou-se que são os enfermeiros que consideram as alterações decorrentes nos últimos dois anos benéficas para o cliente (Mean Rank= 90,04, p=0,001) a manifestar uma satisfação mais elevada; como também foi identificada uma relação estaticamente significativa (moderada e positiva) entre o empenhamento atitudinal e a satisfação dos enfermeiros (p=0,000). Conclusões: As evidências encontradas neste estudo convidam-nos a refletir sobre estratégias que possibilitem, em comunhão de esforços com o enfermeiro e organização, a obtenção de um melhor conhecimento dos determinantes da satisfação que potenciem uma intervenção com vista à sua promoção/melhoria. Palavras-Chave: Satisfação; trabalho, empenhamento atitudinal, enfermeiros, especialistas, reabilitação.

Depression and cardiovascular morbidity and mortality: cause or consequence?

Background Depression after myocardial infarction has been associated with increased cardiovascular mortality. This study assessed whether depressive symptoms were associated with adverse outcomes in people with a history of an acute coronary syndrome, and evaluated possible explanations for such an association. Methods and results Depressive symptoms were assessed using the General Health Questionnaire at least 5 months after hospital admission for acute myocardial infarction or unstable angina in 1130 participants of the Long-Term Intervention with Pravastatin in Ischaemic Disease (LIPID) Study, a multicentre, placebo-controlled, clinical trial of cholesterol-lowering treatment. Cardiovascular symptoms, self-rated general health, cardiovascular risk factors, employment status, social support and life events were also assessed at the baseline visit. Cardiovascular death (n=114), non-fatal myocardial infarction (n=108), non-fatal stroke (n=53) and unstable angina (n=274) were documented during a median follow-up period of 8.1 years. Individuals with depressive symptoms (General. Health Questionnaire score greater than or equal to5; 22% of participants) were more likely to report angina, dyspnoea, claudication, poorer general health, not being in paid employment, few social contacts and/or adverse life events (P

Optimising care of acute coronary syndromes in three Australian hospitals

Objective. To improve quality of in-hospital care of patients with acute coronary syndromes using a multifaceted quality improvement program. Design. Prospective, before and after study of the effects of quality improvement interventions between October 2000 and August 2002. Quality of care of patients admitted between 1 October 2000 and 16 April 2001 (baseline) was compared with that of those admitted between 15 February 2002 and 31 August 2002 (post-intervention). Setting. Three teaching hospitals in Brisbane, Australia. Study participants. Consecutive patients (n = 1594) admitted to hospital with acute coronary syndrome [mean age 68 years (SD 14 years); 65% males]. Interventions. Clinical guidelines, reminder tools, and educational interventions; 6-monthly performance feedback; pharmacist-mediated patient education program; and facilitation of multidisciplinary review of work practices. Main outcome measures. Changes in key quality indicators relating to timing of electrocardiogram (ECG) and thrombolysis in emergency departments, serum lipid measurement, prescription of adjunctive drugs, and secondary prevention. Results. Comparing post-intervention with baseline patients, increases occurred in the proportions of eligible patients: (i) undergoing timely ECG (70% versus 61%; P = 0.04); (ii) prescribed angiotensin-converting enzyme inhibitors (70% versus 60%; P = 0.002) and lipid-lowering agents (77% versus 68%; P = 0.005); (iii) receiving cardiac counselling in hospital (57% versus 48%; P = 0.009); and (iv) referred to cardiac rehabilitation (17% versus 8%; P < 0.001). Conclusions. Multifaceted approaches can improve care processes for patients hospitalized with acute coronary syndromes. Care processes under direct clinician control changed more quickly than those reliant on complex system factors. Identifying and overcoming organizational impediments to quality improvement deserves greater attention.

Viscosupplementation for the treatment of osteoarthritis of the knee (Review)

Background Osteoarthritis (OA) is the most prevalent chronic joint disorder worldwide and is associated with significant pain and disability. Objectives To assess the effects of viscosupplementation in the treatment of OA of the knee. The products were hyaluronan and hylan derivatives (Adant, Arthrum H, Artz (Artzal, Supartz), BioHy (Arthrease, Euflexxa, Nuflexxa), Durolane, Fermathron, Go-On, Hyalgan, Hylan G-F 20 (Synvisc Hylan G-F 20), Hyruan, NRD-101 (Suvenyl), Orthovisc, Ostenil, Replasyn, SLM-10, Suplasyn, Synject and Zeel compositum). Search strategy MEDLINE (up to January (week 1) 2006 for update), EMBASE, PREMEDLINE, Current Contents up to July 2003, and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched. Specialised journals and reference lists of identified randomised controlled trials (RCTs) and pertinent review articles up to December 2005 were handsearched. Selection criteria RCTs of viscosupplementation for the treatment of people with a diagnosis of OA of the knee were eligible. Single and double-blinded studies, placebo-based and comparative studies were eligible. At least one of the four OMERACT III core set outcome measures had to be reported (Bellamy 1997). Data collection and analysis Each trial was assessed independently by two reviewers for its methodological quality using a validated tool. All data were extracted by one reviewer and verified by a second reviewer. Continuous outcome measures were analysed as weighted mean differences (WMD) with 95% confidence intervals (CI). However, where different scales were used to measure the same outcome, standardized mean differences (SMD) were used. Dichotomous outcomes were analyzed by relative risk (RR). Main results Seventy-six trials with a median quality score of 3 (range 1 to 5) were identified. Follow-up periods varied between day of last injection and eighteen months. Forty trials included comparisons of hyaluronan/hylan and placebo (saline or arthrocentesis), ten trials included comparisons of intra-articular (IA) corticosteroids, six trials included comparisons of nonsteroidal anti-inflammatory drugs (NSAIDs), three trials included comparisons of physical therapy, two trials included comparisons of exercise, two trials included comparisons of arthroscopy, two trials included comparisons of conventional treatment, and fifteen trials included comparisons of other hyaluronans/hylan. The pooled analyses of the effects of viscosupplements against 'placebo' controls generally supported the efficacy of this class of intervention. In these same analyses, differential efficacy effects were observed for different products on different variables and at different timepoints. Of note is the 5 to 13 week post injection period which showed a percent improvement from baseline of 28 to 54% for pain and 9 to 32% for function. In general, comparable efficacy was noted against NSAIDs and longer-term benefits were noted in comparisons against IA corticosteroids. In general, few adverse events were reported in the hyaluronan/hylan trials included in these analyses. Authors' conclusions Based on the aforementioned analyses, viscosupplementation is an effective treatment for OA of the knee with beneficial effects: on pain, function and patient global assessment; and at different post injection periods but especially at the 5 to 13 week post injection period. It is of note that the magnitude of the clinical effect, as expressed by the WMD and standardised mean difference (SMD) from the RevMan 4.2 output, is different for different products, comparisons, timepoints, variables and trial designs. However, there are few randomised head-to-head comparisons of different viscosupplements and readers should be cautious, therefore, in drawing conclusions regarding the relative value of different products. The clinical effect for some products, against placebo, on some variables at some timepoints is in the moderate to large effect-size range. Readers should refer to relevant tables to review specific detail given the heterogeneity in effects across the product class and some discrepancies observed between the RevMan 4.2 analyses and the original publications. Overall, the analyses performed are positive for the HA class and particularly positive for some products with respect to certain variables and timepoints, such as pain on weight bearing at 5 to 13 weeks postinjection. In general, sample-size restrictions preclude any definitive comment on the safety of the HA class of products; however, within the constraints of the trial designs employed no major safety issues were detected. In some analyses viscosupplements were comparable in efficacy to systemic forms of active intervention, with more local reactions but fewer systemic adverse events. In other analyses HA products had more prolonged effects than IA corticosteroids. Overall, the aforementioned analyses support the use of the HA class of products in the treatment of knee OA.

A systematic review of successes and failures in home telehealth: preliminary results

We conducted a systematic review of the literature to identify studies in home telehealth that compared a home telehealth intervention with a non-telehealth standard/usual care alternative in terms of administrative changes, patient management decisions, patient outcomes, caregiver outcomes, economic impact or social impact on patients. A search of various databases produced 6643 references. Of these 769 papers were selected for more detailed investigation. These papers, combined with hand searching of relevant telehealth journals and cross-referencing of citations in identified publications, resulted in 138 papers referring to 130 projects for review. In this preliminary analysis we used a quality appraisal approach that took into account the study design. An additional analysis of patient numbers was then used to calculate a net evidence score. A large proportion of studies (80%) were randomised controlled trials. Only 22 projects (17%) reported economic data deemed to be sufficient for appraisal. Evidence exists for the clinical effectiveness of home telehealth in diabetes, the general area of mental health, high risk pregnancy monitoring, heart failure and cardiac disease.

Idiopathic sclerosing orbital inflammation

Objective: To perform a multicenter review of the clinical features and treatment of 31 patients with idiopathic sclerosing orbital inflammation. Methods: We included all patients with histologically confirmed idiopathic sclerosing orbital inflammation from 5 regional orbital centers. We reviewed the case notes to determine the clinical presentation, diagnostic features, and response to treatment. The main outcome measures were duration and nature of symptoms, anatomical location of disease, histopathological findings, treatment modalities, treatment efficacy and adverse effects, and final clinical status. Results: We included 13 male and 18 female patients ranging in age from 7 to 83 years. The average duration of symptoms at presentation was 13.4 months. There was a predilection for the lateral and superior quadrants. Thirteen patients had apical disease, and 4 had extraorbital involvement. Histopathological findings invariably showed sclerosis associated with a sparse mixed cellular infiltrate. Twenty- seven patients were treated with oral prednisolone, response to which was good in 9 patients, partial in 11, and poor in 7. Six patients were treated with a second- line immunosuppressive agent, and 6 received radiotherapy. The response to radiotherapy was generally poor. Conclusions: Idiopathic sclerosing orbital inflammation is a rare condition that can be difficult to diagnose and manage. Early intervention with immunosuppression in the form of corticosteroids combinedwith secondline agents can result in control and even regression of the disease.

OPINIÃO DE CRIANÇAS SOBRE O LAR DE LONGA PERMANÊNCIA PARA IDOSOS: MUDANÇAS POR CONTATO LÚDICO

Esta pesquisa verifica a opinião da criança por meio do desenho sobre o Lar de Longa Permanência para Idosos, antes e depois de contato lúdico com idosos institucionalizados. Para melhor caracterizar a população idosa, traça seu perfil neuropsicológico. Desenvolve-se junto a 21 idosos institucionalizados e 61 crianças com idades entre 7 e 12 anos, do Ensino Fundamental público. Inicia-se por verificar a opinião destas crianças sobre Asilo, por meio de desenho. Em seguida, realiza intervenção lúdica com crianças e idosos, de 10 encontros com brincadeiras simbólicas e jogos de regras. A seguir, reavalia a opinião das crianças e faz avaliação neuropsicológica dos idosos, por meio de Mini-Exame do Estado Mental, da Escala de Depressão Geriátrica, do Short-Form Health Survey (SF-36) e do Índice de Katz. Para verificar a opinião das crianças expressa por meio do desenho, utiliza de um título em aberto “Asilo é...”, a ser completado. Eles são analisados com subsídios do teste projetivo House-Tree-Person (HTP). Os resultados demonstram que houve, de uma aplicação para outra, alteração na opinião de 67% das crianças, que manifestaram opinião mais positiva relativa a perceber os idosos mais interativos e o Asilo mais humanizado, por meio de desenhos mais coloridas, de casas com portas e janelas, de pessoas sorrindo e em movimento e de mensagens afetuosas. Como aspectos negativos, encontram-se maior número de grades e de pessoas desenhadas sem face, o que pode representar a percepção da criança da dificuldade de contato do idoso com o mundo externo. Na análise estatística, encontrou-se média geral de 0,34 e desvio padrão de 0,16, no primeiro desenho e, no segundo, média de 0,42 e desvio padrão de 0,19, com médias obtidas numa escala de 0 a 1, em que se considera positivo o valor próximo a 1. Na avaliação neuropsicológica dos idosos, no MEEM, 50% demonstram preservação cognitiva. Os demais instrumentos indicam que a maior parte deles não apresenta sintomas depressivos, emite opinião positiva com relação à própria saúde, participa das atividades lúdicas e é dependente. Este estudo ressalta contudo que as características da instituição pesquisada, juntamente com a realização de atividades lúdicas, podem ter favorecido a opinião das crianças após seu contato com o Asilo. O estudo indica a necessidade de novas pesquisas sobre interação criança-idoso institucionalizado

MANEJO TÉCNICO DO ATENDIMENTO PSICOLÓGICO EM AMBULATÓRIO DE REPRODUÇÃO HUMANA ASSISTIDA

O presente estudo teve por objetivos: descrever o manejo técnico do atendimento psicológico, ilustrado pelo caso de uma paciente infértil de um ambulatório de reprodução humana assistida; descrever as vicissitudes no campo analítico nestes atendimentos; e sistematizar esse manejo técnico em intervenções ambulatoriais em que se privilegia a compreensão das relações transferenciais. O instrumento utilizado para a coleta de dados foram os próprios atendimentos, ou entrevistas psicológicas, baseadas no método clínico de abordagem psicanalítica. A análise e a discussão dos resultados se basearam na apresentação de um único caso, que ilustrou a técnica que se objetivou sistematizar e descrever. É apresentado o caso da Sra. S., uma mulher de 41 anos, com parceiro em união estável há cinco anos, que realizava tratamento de infertilidade no ambulatório de reprodução humana. A paciente foi atendida pela psicóloga no próprio ambulatório durante o período da segunda tentativa de gravidez. Foram realizados efetivamente três (3) atendimentos e, no período de dois meses, a paciente não compareceu a três (3) sessões. Foram criadas cinco (5) categorias de análise: 1) Escuta; 2) Configuração de Queixa Psicológica; 3) Manejo dos Conflitos; 4) Manejo da Transferência; e 5) Enquadre. Estas categorias representaram elementos do atendimento. A divisão do atendimento em categorias teve propósito didático, no entanto, a sistematização do manejo deu-se a partir do desenvolvimento destas categorias, mas não numa ordem pré-estabelecida. A Escuta refere-se à capacidade do psicoterapeuta compreender a relação estabelecida com o paciente, assim como os elementos metapsicológicos depositados no campo, a partir de seu quadro de referência teórico-metodológico. A Configuração de Queixa Psicológica refere-se à aproximação do sofrimento psíquico e dos conflitos que subjazem à queixa orgânica ou manifesta. O Manejo dos Conflitos representa o modo como são interpretados e devolvidos a um paciente os conteúdos trazidos para a sessão. Ressalta-se, no manejo dos conflitos, a eleição de um foco de trabalho em que se privilegia a situação atual da vida do paciente relacionada especificamente à sua queixa. O Manejo da Transferência refere-se à forma como os aspectos transferenciais são compreendidos e devolvidos ao paciente. A neurose e psicose de transferência são evitadas e o trabalho é preferencialmente desenvolvido a partir da interpretação de situações extra-transferenciais. Por fim, o Enquadre engloba todos os aspectos formais e dinâmicos que constituem o campo emocional sobre o qual se trabalha. Este tipo de atendimento pode ser situado entre a entrevista psicológica e o atendimento em psicoterapia breve com objetivos e tempo limitados, variando de acordo com a qualidade adaptativa do paciente e sua motivação para o atendimento psicológico. Concluímos que este modelo de atendimento ambulatorial engloba aspectos tanto diagnósticos quanto de intervenção e que o papel do psicólogo neste contexto é auxiliar o paciente atendido a compreender sua queixa em seus aspectos latentes e manifestos, além de propiciar um espaço de escuta em que os conteúdos trazidos podem ser pensados e compreendidos

Effect of β-adrenoceptor antagonists on autonomic control of ciliary smooth muscle

Purpose: Pharmacological intervention with peripheral sympathetic transmission at ciliary smooth muscle neuro-receptor junctions has been used against a background of controlled parasympathetic activity to investigate the characteristics of autonomic control of ocular accommodation. Methods: A continuously recording infrared optometer was used to measure accommodation on a group of five visually normal emmetropic subjects under open- and closed-loop conditions. A double-blind protocol between saline, timolol and betaxolol was used to differentiate between the localised action on ciliary smooth muscle and effects induced by changes in stimulus conditions. Data were collected before and 45 min following the instillation of saline, timolol or betaxolol. Open-loop post-task decay was investigated following 3 min sustained near fixation of a stimulus placed 3 D above the subject's pre-task tonic accommodation level. Closed-loop dynamic responses were recorded for each treatment condition while subjects viewed sinusoidally (0.05-0.6 Hz) or stepwise vergence-modulated targets over a 2 D range (2-4 D). Results: Open-loop data demonstrate a rapid post-task regression to pre-task tonic accommodation levels for saline and betaxolol control conditions. A slow positive post-task shift was induced by timolol indicating that sympathetic inhibition contributes to accommodative adaptation during sustained near vision. Closed-loop accommodation responses to temporally modulated sinusoidal stimuli showed characteristic features for both saline and betaxolol control conditions. Timolol induced a reduced gain for low- and mid-temporal frequencies (< 0.3 Hz) but did not affect the response at higher temporal frequencies. Response times to stepwise stimuli increased following the instillation of timolol for the near-to-far fixation condition compared with the controls and was related to the period of sustained prior fixation. Conclusions: Modulation of accommodation under open- and closed-loop conditions by a non-selective β-blocker is consistent with the temporal and inhibitory features of sympathetic innervation to ciliary smooth muscle. Although parasympathetic innervation predominates there is evidence to support a role for sympathetic innervation in the control of ocular accommodation. © 2002 The College of Optometrists.

Auto plant closures, policy responses and labour market outcomes:a comparison of MG Rover in the UK and Mitsubishi in Australia

This paper provides a preliminary comparative longitudinal analysis of the impact on workers made redundant due to the closure of the Mitsubishi plant in Adelaide and the MG Rover plant in Birmingham. Longitudinal surveys of ex-workers from both firms were undertaken over a 12-month period in order to assess the process of labour market adjustment. In the Mitsubishi case, given the skills shortage the state of Adelaide was facing, together with the considerable growth in mining and defence industries, it would have been more appropriate if policy intervention had been redirected to further training or re-skilling opportunities for redundant workers. This opportunity was effectively missed and as a result more workers left the workforce, most notably for retirement, than could have otherwise been the case. The MG Rover case was seen as a more successful example of policy intervention, with greater funding assistance available and targeted support available, and with more emphasis on re-training needs to assist adjustment. However, despite the assistance offered and the rhetoric of successful adjustment in both cases, the majority of workers have nevertheless experienced deterioration in their circumstances particularly in the Australian case where casual and part-time work were often the only work that could be obtained. Even in the UK case, where more funding assistance was offered, a majority of workers reported a decline in earnings and a rise in job insecurity. This suggests that a reliance on the flexible labour market is insufficient to promote adjustment, and that more active policy intervention is needed especially in regard to further up-skilling.

Plasma vascular endothelial growth factor, angiopoietin-2, and soluble angiopoietin receptor tie-2 in diabetic retinopathy:effects of laser photocoagulation and angiotensin receptor blockade

Background: Proliferative diabetic retinopathy (PDR) may be a response to abnormal angiogenic growth factors such as vascular endothelial growth factor (VEGF), angiopoietin-2 (Ang-2), and the soluble angiopoietin receptor tie-2. The authors hypothesised the following: (a) there are differences in plasma levels of these growth factors in different grades of diabetic retinopathy; and (b) that the effects of intervention with panretinal laser photocoagulation (PRP) for PDR, and angiotensin receptor blockade (using eprosartan) for patients with other grades of diabetic retinopathy will be to reduce levels of the growth factors. Methods: Cross sectional and interventional study (using PRP and eprosartan) in diabetic patients. VEGF, Ang-2, and tie-2 were measured by ELISA. Results: VEGF (p<0.001) and Ang-2 levels (p<0.001) were significantly higher in 93 diabetic patients compared to 20 healthy controls, with the highest levels in grade 2 and grade 3 diabetic retinopathy (p<0.05). Tie-2 was lower in diabetics compared to controls (p = 0.008), with no significant differences between the diabetic subgroups. Overall, VEGF significantly correlated with Ang-2 (p<0.001) and tie-2 (p = 0.004) but the correlation between Ang-2 and tie-2 levels was not significant (p = 0.065). Among diabetic patients only, VEGF levels were significantly correlated with Ang-2 (p<0.001) and tie-2 (p<0.001); the correlation between Ang-2 and tie-2 levels was also significant (p<0.001). There were no statistically significant effects of laser photocoagulation on plasma VEGF, Ang-2, and tie-2 in the 19 patients with PDR, or any effects of eprosartan in the 28 patients with non-proliferative diabetic retinopathy. Conclusion: Increased plasma levels of VEGF and Ang-2, as well as lower soluble tie-2, were found in diabetic patients. The highest VEGF and Ang-2 levels were seen among patients with pre-proliferative and proliferative retinopathy, but there was no relation of tie-2 to the severity of retinopathy. As the majority of previous research into Ang-2 and tie-2 has been in relation to angiogenesis and malignancy, the present study would suggest that Ang-2 and tie-2 may be used as potential indices of angiogenesis in diabetes mellitus (in addition to VEGF) and may help elucidate the role of the angiopoietin/tie-2 system in this condition.

An almond-enriched diet increases plasma α-tocopherol and improves vascular function but does not affect oxidative stress markers or lipid levels

Vascular dysfunction is one of the major causes of cardiovascular (CV) mortality and increases with age. Epidemiological studies suggest that Mediterranean diets and high nut consumption reduce CV disease risk and mortality while increasing plasma α-tocopherol. Therefore, we have investigated whether almond supplementation can improve oxidative stress markers and CV risk factors over 4 weeks in young and middle-aged men. Healthy middle-aged men (56 ± 5.8 years), healthy young men (22.1 ± 2.9 years) and young men with two or more CV risk factors (27.3 ± 5 years) consumed 50 g almond/day for 4 weeks. A control group maintained habitual diets over the same period. Plasma α-tocopherol/cholesterol ratios were not different between groups at baseline and were significantly elevated by almond intervention with 50 g almond/day for 4 weeks (p < 0.05). Plasma protein oxidation and nitrite levels were not different between groups whereas, total-, HDL- and LDL-cholesterols and triglycerides were significantly higher in healthy middle-aged and young men with CV risk factors but were not affected by intake. In the almond-consuming groups, flow-mediated dilatation (FMD) improved and systolic blood pressure reduced significantly after 50 g almonds/day for 4 weeks, but diastolic blood pressure reduced only in healthy men. In conclusion, a short-term almond-enriched diet can increase plasma α-tocopherol and improve vascular function in asymptomatic healthy men aged between 20 and 70 years without any effect on plasma lipids or markers of oxidative stress. © 2014 Informa UK, Ltd.

Avandamet:Combined metformin-rosiglitazone treatment for insulin resistance in type 2 diabetes

Insulin resistance is a major endocrinopathy underlying the development of hyperglycaemia and cardiovascular disease in type 2 diabetes. Metformin (a biguanide) and rosiglitazone (a thiazolidinedione) counter insulin resistance, acting by different cellular mechanisms. The two agents can be used in combination to achieve additive glucose-lowering efficacy in the treatment of type 2 diabetes, without stimulating insulin secretion and without causing hypoglycaemia. Both agents also reduce a range of atherothrombotic factors and markers, indicating a lower cardiovascular risk. Early intervention with metformin is already known to reduce myocardial infarction and increase survival in overweight type 2 patients. Recently, a single-tablet combination of metformin and rosiglitazone, Avandamet, has become available. Avandamet is suitable for type 2-diabetic patients who are inadequately controlled by monotherapy with metformin or rosiglitazone. Patients already receiving separate tablets of metformin and rosiglitazone may switch to the single-tablet combination for convenience. Also, early introduction of the combination before maximal titration of one agent can reduce side effects. Use of Avandamet requires attention to the precautions for both metformin and rosiglitazone, especially renal, cardiac and hepatic competence. In summary, Avandamet is a single-tablet metformin-rosiglitazone combination that doubly targets insulin resistance as therapy for hyperglycaemia and vascular risk in type 2 diabetes. © 2004 Blackwell Publishing Ltd.

Medical students' personal experience of high-stakes failure:case studies using interpretative phenomenological analysis

Abstract (provisional): Background Failing a high-stakes assessment at medical school is a major event for those who go through the experience. Students who fail at medical school may be more likely to struggle in professional practice, therefore helping individuals overcome problems and respond appropriately is important. There is little understanding about what factors influence how individuals experience failure or make sense of the failing experience in remediation. The aim of this study was to investigate the complexity surrounding the failure experience from the student’s perspective using interpretative phenomenological analysis (IPA). Methods The accounts of 3 medical students who had failed final re-sit exams, were subjected to in-depth analysis using IPA methodology. IPA was used to analyse each transcript case-by-case allowing the researcher to make sense of the participant’s subjective world. The analysis process allowed the complexity surrounding the failure to be highlighted, alongside a narrative describing how students made sense of the experience. Results The circumstances surrounding students as they approached assessment and experienced failure at finals were a complex interaction between academic problems, personal problems (specifically finance and relationships), strained relationships with friends, family or faculty, and various mental health problems. Each student experienced multi-dimensional issues, each with their own individual combination of problems, but experienced remediation as a one-dimensional intervention with focus only on improving performance in written exams. What these students needed to be included was help with clinical skills, plus social and emotional support. Fear of termination of the their course was a barrier to open communication with staff. Conclusions These students’ experience of failure was complex. The experience of remediation is influenced by the way in which students make sense of failing. Generic remediation programmes may fail to meet the needs of students for whom personal, social and mental health issues are a part of the picture.
