This article describes the results of the first phase of a research project to develop, implement, evaluate, and improve arts therapies interventions for young offenders in secure care. By means of a naturalistic/constructivistic research methodology in combination with grounded therapy methodology, practice-based evidence has been generated. Core problems of young offenders that are connected to delinquency have been described and arts therapies interventions have been developed that can be used to change these core problems. Core problems are problems with self-image, with expressing and discharging emotions, the inability to resolve interpersonal problems and finally, negative cognitions. In co-creation with practitioners, interventions have been developed for drama therapy, music therapy, art therapy and dance-movement therapy. A treatment theory has been developed that explains the working of arts therapies by means of the first author's theory of analogy. This theory explains arts therapies by means of the equality between forms of expression in art and the core self consciousness as described by Damasio and the vitality affects within the core self as described by Stern. 相似文献

BACKGROUND: To compare outcomes following endovascular repair in abdominal aortic aneurysm (AAA) patients with and without concomitant iliac artery aneurysm disease. METHODS: Data on patient characteristics and risk factors, aneurysm morphology, interventional details, complications, and mortality were retrieved from the EUROSTAR registry database for the period from October 1996 to November 2006. AAA patients without concomitant iliac aneurysm disease (group I, n = 6286) were compared to 1268 patients with aneurysmal iliac vessels (group II) regarding mortality, device-related complications, and need for secondary interventions. Logistic regression and Cox proportional hazards model were performed to assess independent associations with outcome parameters in the study groups. RESULTS: Group II had more patients classified as ASA III or IV (55.1% versus 50.3% in group I; p = 0.002); they were more frequently unfit for open aortic repair (30.3% versus 23.4%; p<0.0001) and had larger-diameter aneurysms (62.3 versus 60.7 mm; p<0.0001) and infrarenal necks (24.5 versus 24.1 mm; p<0.001). In addition, group II patients had a higher rate of internal iliac artery occlusion (11.4% versus 5.2%; p<0.0001) and more significant angulation of the aortic neck (30.8% versus 24.3%; p<0.0001) and iliac artery (48.3% versus 41.9%; p<0.0001). Group II patients had higher 5-year cumulative incidences of distal type I endoleaks (9.1% versus 4.3%; p<0.0001), iliac limb occlusion (5.9% versus 4.4%; p = 0.040), secondary transfemoral intervention (17.6% versus 8.9%; p = 0.019), and aneurysm rupture (4.5% versus 1.7%; p = 0.042). CONCLUSION: Although aneurysm-related mortality and mortality from other causes were similar in both study groups, concomitant iliac artery aneurysms in AAA patients were associated with an increased incidence of distal type I endoleak, iliac limb occlusion, and aneurysm rupture. Therefore, caution is warranted, and efforts should be made to avoid procedural mishaps. 相似文献

A case of the nephrotic syndrome with unilateral renal vein thrombosis is reported. The patient, an 18 year old man, presented with a six month history of edema and the recent development of a left-sided varicocele. An enlarged left kidney and a thrombus in the left renal vein were demonstrated roentgenographically. A biopsy specimen of the right kidney was interpreted as membranous glomerulonephritis. Selective renal function studies showed nearly identical creatinine excretion, and similar total protein excretion and protein selectivity from each kidney. Thus, the thrombus in the left renal vein did not influence glomerular filtration rate or quantitative or qualitative protein excretion. A high urinary output and a decreased serum level of antithrombin III were measured. These findings suggest a mechanism to explain the increased thrombotic tendency seen in this and other patients with the nephrotic syndrome. 相似文献

Association of mannose-binding lectin genotype with cardiovascular abnormalities in Kawasaki disease
Biezeveld MH Kuipers IM Geissler J Lam J Ottenkamp JJ Hack CE Kuijpers TW 《Lancet》2003,361(9365):1268-1270
Kawasaki disease is an acute vasculitis of possible infectious cause, which in particular affects the coronary arteries. Young children rely mostly on their innate immune system for protection against invading microorganisms, of which mannose-binding lectin is an important component. We aimed to investigate the possible role of the gene for this molecule (MBL) in white Dutch patients with Kawasaki disease. In 90 patients, frequency of mutations in the MBL gene was higher than in healthy children. In children younger than 1 year, those with mutations were at higher risk of development of coronary artery lesions than were those without (odds ratio 15.7, 95% CI 1.4-176.5, p=0.026). Our findings suggest that the innate immune system contributes differently to pathophysiology of Kawasaki disease at various ages. 相似文献
