BackgroundMental health literacy (MHL) refers to an individual's knowledge of mental disorders, including the ability to recognize psychopathology and being aware of help options. Most studies of MHL have focused on adults.ObjectiveThe purpose of this study was to examine levels of MHL among adolescents.MethodsMHL was examined using two pre-established vignettes that presented an adolescent with symptoms of either depression or schizophrenia. The respondents were 426 adolescents (age mean = 16). Vignette data were analyzed both qualitatively and quantitatively.ResultsThe data showed that 42.7% and 34.7% of the respondents identified depression and schizophrenia, respectively. Depression was recognized more often by females than males. Professional help was suggested by a minority of the respondents for managing symptoms of depression (22.5%) or schizophrenia (32.6%). Altruistic behaviors, examined through the willingness to help an acquaintance with mental illness symptoms, were apparent among 58.2% of the respondents and to a greater extent in females than males. Answers following the schizophrenia vignette also revealed stigmatizing attitudes in 11.5% of the participants.ConclusionsThere are relatively low levels of MHL among teenagers in Sweden. Awareness campaigns and the implementation of psychoeducation in the school curriculum could increase MHL in this group. 相似文献

Gallbladder cancer is an aggressive tumor. Its incidence varies according to geography. Surgery is the standard treatment for localized stage but there is no standard treatment in metastatic or locally advanced disease. Because of the rarity of bile tract cancer (BTC) and gallblader carcinoma (GBC), most studies have grouped all BTC and GBC together, and there are very few GBC-specific studies. In addition, there is a paucity of randomized controlled studies in this disease with small numbers of patients and inclusion bias. One randomized trial ABC-02?was well conducted and showed a survival benefit in favor of gemcitabine (GEM)+cisplatin (CDDP), which can be regarded as the standard in locally advanced BTC. Adjuvant therapy after surgical resection is not validated. Understanding the molecular mechanisms of carcinogenesis of GBC has opened the way for the use of targeted therapies. This new treatment would improve survival and quality of life of our patients. 相似文献

Intracellular K(+) plays an important role in controlling ion homeostasis for maintaining cell volume and inhibiting activity of pro-apoptotic enzymes. Cytoplasmic K(+) concentration is regulated by K(+) uptake via Na(+) -K(+) -ATPase and K(+) efflux through K(+) channels in the plasma membrane. The IsK (KCNE1) protein is known to co-assemble with KCNQ1 (KvLQT1) protein to form a K(+) channel underlying the slowly activating delayed rectifier K(+) outward current which delays voltage activation. In order to further study the activity and cellular localization of IsK protein, we constructed a C-terminal fusion of IsK with EGFP (enhanced green fluorescent protein). Expression of the fusion protein appeared as clusters located in the plasma membrane and induced degeneration of both transiently or stably transfected cells. 相似文献

PURPOSE: To report a retrospective evaluation of the efficacy and midterm clinical results of the Anaconda stent-graft in the endovascular repair of infrarenal abdominal aortic aneurysms. METHODS: Fifty-one patients (48 men; mean age 71+/-8 years, range 62-89) were treated with the Anaconda stent-graft from January 2006 to September 2007. Six patients were considered at high risk for open repair (defined as ASA grade 3) and 10 had undergone previous laparotomy. The mean neck diameter and length were 26 mm (range 22-30) and 18.5 mm (range 14-35), respectively. Mean proximal neck angulation was 30 degrees (range 5-60). Severe iliac artery tortuosity (>60 degrees ) was seen in 20 (39%) patients; 3 (6%) had a proximal aneurysm neck angle >45 degrees. RESULTS: The technical success rate was 100%; intraprocedurally, 7 (14%) stent-grafts were repositioned to address renal artery occlusion by the graft (n = 1) or type I endoleak. This maneuver resolved 6 of the 7 situations; a remaining endoleak required a proximal cuff to seal it. The procedural success rate (no major complication at 30 days) was 94%. The mean follow-up was 16 months (range 1-21). Five (10%) endoleaks (1 type I, 4 type II) and 1 (2%) graft migration occurred. The overall reintervention rate was 6%. Two (4%) patients died in late follow-up. CONCLUSION: The Anaconda stent-graft appears both safe and effective in terms of midterm clinical outcome and compares favorably with previously reported EVAR results. The ability to reposition the stent-graft is a particular advantage. 相似文献

The authors estimated noninvasively the wall stress distribution for actual abdominal aortic aneurysms (AAAs) in vivo on a patient-to-patient basis and correlated the peak wall stress (PWS) with various geometrical parameters. They studied 39 patients (37 men, mean age 73.7 +/- 8.2 years) with an intact AAA (mean diameter 6.3 +/- 1.7 cm) undergoing preoperative evaluation with spiral computed tomography (CT). Real 3-dimensional AAA geometry was obtained from image processing. Wall stress was determined by using a finite-element analysis. The aorta was considered isotropic with linear material properties and was loaded with a static pressure of 120.0 mm Hg. Various geometrical parameters were used to characterize the AAAs. PWS and each of the geometrical characteristics were correlated by use of Pearson's rank correlation coefficients. PWS varied from 10.2 to 65.8 N/cm2 (mean value 37.1 +/- 9.9 N/cm2). Among the geometrical parameters, the PWS was well correlated with the mean centerline curvature, the maximum centerline curvature, and the maximum centerline torsion of the AAAs. The correlation of PWS with maximum diameter was nonsignificant. Multiple regression analysis revealed that the mean centerline curvature of the AAA was the only significant predictor of PWS and subsequent rupture risk. This noninvasive computational approach showed that geometrical parameters other than the maximum diameter are better indicators of AAA rupture. 相似文献

Accurate assessment of energy requirements of humans under various physiological, pathological, and environmental conditions is hampered by the high cost of techniques for measuring daily energy expenditure. A room respirometer novel in its novel in its low cost of construction and simplicity of operation is described, together with an appreciation of errors and assumptions. It is suitable for measurements of daily energy expenditure in humans with an accuracy of +/- 1.5% and can be reproduced without difficulty in both developed and developing countries. 相似文献
