The Effectiveness of a Self-Efficacy-Focused Structured Education Program (SSEP) in Improving Metabolic Control and Psychological Outcomes of Type 2 Diabetes Patients: A 12-Month Follow-Up of a Multicenter Randomized Controlled Trial.

BACKGROUND AND OBJECTIVE: The 12-month follow-up effect of the self-efficacy-focused structured education program (SSEP) requires in-depth confirmation. This study aims to verify whether the benefits of SSEP can be maintained in 12 months. MATERIALS AND METHODS: A multicenter randomized controlled trial with 12-month follow-up conducted among 265 type 2 diabetes patients not on insulin from 4 hospitals in mainland China. The intervention group (n = 133) was administrated with SSEP, and the control group (n = 132) received the routine education. The indicators of metabolic and psychosocial aspects of the patients were assessed at baseline and 12 months. RESULTS: As opposed to the control group, the primary outcomes of HbA1c in the intervention group were improved obviously in the 12th month during the 12-month follow-up (-1.13%, P < 0.001). The secondary outcomes (ie, waist circumference, total cholesterol, low-density lipoprotein cholesterol, diabetes self-efficacy, diabetes self-management behaviors, diabetes knowledge and diabetes distress) were improved significantly in the intervention group as compared with the control group in the 12th month during the 12-month follow-up (-3.14 cm, P = 0.001; -0.30 mmol/L, P = 0.032; -0.25 mmol/L, P = 0.008; 0.87, P < 0.001; 10.67, P < 0.001; 3.42, P < 0.001; -4.97, P < 0.001). The non-significant difference in the secondary outcomes (ie, systolic pressure, diastolic pressure, triglycerides and high-density lipoprotein cholesterol) was identified between the two groups in the 12th month during the 12-month follow-up (P > 0.05). CONCLUSION: The SSEP provided sustainable benefits in outcomes of HbA1c, waist circumference, total cholesterol, low-density lipoprotein cholesterol, diabetes knowledge, diabetes distress, diabetes self-efficacy and diabetes self-management behaviors for type 2 diabetes patients not on insulin in the 12th month during the 12-month follow-up. Thus, it will be an effective education model capable of being generalized nationwide, and it can be referenced for the nations and regions under consistent conditions.

The effectiveness of a self-efficacy-focused structured education programme on adults with type 2 diabetes: A multicentre randomised controlled trial.

AIMS AND OBJECTIVES: To evaluate the effectiveness of a self-efficacy-focused structured education programme on outcomes in adults with type 2 diabetes (T2DM) without insulin therapy. BACKGROUND: Structured education regarding metabolic control in T2DM adults without insulin therapy has not always been effective, and this lack of effectiveness might be due to overlooking self-efficacy. Whether a self-efficacy-focused structured education programme could improve metabolic and psychosocial outcomes for T2DM adults more effectively remains unknown. DESIGN: A multicentre parallel randomised controlled concealed label trial. METHODS: The study conducted in outpatients of four hospitals in China. A total of 265 T2DM adults without insulin therapy were randomly assigned to an intervention group of a self-efficacy-focused structured education programme (n = 133), or to a control group of routine education (n = 132). The differences in metabolic and psychosocial outcomes were investigated at baseline, three- and 6-month follow-ups. RESULTS: The primary outcome of A1C and the secondary outcomes of weight, body mass index, waist circumference, diastolic pressure, self-efficacy, self-management behaviours and knowledge improved significantly in the intervention group compared with the control group at 6-month follow-up. The differences in A1C between groups for patients with a low educational background at 6-month follow-up were significant. No significant differences were found in other secondary outcomes of systolic pressure, the blood lipid profile and diabetes distress between groups at 6-month follow-up. CONCLUSIONS: This programme can improve glycaemic control, weight control, diastolic pressure, self-efficacy, self-management behaviours and diabetes knowledge for T2DM adults. RELEVANCE TO CLINICAL PRACTICE: This self-efficacy-focused structured education programme is effective and can be incorporated into regular clinical care and led by trained staff (e.g. nurses), and it can be implemented in patients with low educational backgrounds.

Tumstatin transfected into human glioma cell line U251 represses tumor growth by inhibiting angiogenesis.

BACKGROUND: Angiogenesis is a prerequisite for tumor growth and plays an important role in rapidly growing tumors, such as malignant gliomas. A variety of factors controlling the angiogenic balance have been described, and among these, the endogenous inhibitor of angiogenesis, tumstatin, has drawn considerable attention. The current study investigated whether expression of tumstatin by glioma cells could alter this balance and prevent tumor formation. METHODS: We engineered stable transfectants from human glioma cell line U251 to constitutively secrete a human tumstatin protein with c-myc and polyhistidine tags. Production and secretion of the tumstatin-c-myc-His fusion protein by tumstatin-transfected cells were confirmed by Western blotting analysis. In the present study, we identify the anti-angiogenic capacity of tumstatin using several in vitro and in vivo assays. Student's t-test and one-way analysis of variance (ANOVA) test were used to determine the statistical significance in this study. RESULTS: The tumstatin transfectants and control transfectants (stably transfected with a control plasmid) had similar in vitro growth rates compared to their parental cell lines. However, the conditioned medium from the tumstatin transfected tumor cells significantly inhibits proliferation and causes apoptosis of endothelial cells. It also inhibits tube formation of endothelial cells on Matrigel. Examination of armpit tumors arising from cells overexpressing tumstatin repress the growth of tumor, accompanying the decreased density of CD31 positive vessels in tumors ((5.62 ± 1.32)/HP), compared to the control-transfectants group ((23.84 + 1.71)/HP) and wild type U251 glioma cells group ((29.33 + 4.45)/HP). CONCLUSION: Anti-angiogenic gene therapy using human tumstatin gene may be an effective strategy for the treatment of glioma.

The expression of moesin in astrocytoma: correlation with pathologic grade and poor clinical outcome.

Moesin, a member of the ERM family, acts as a linker between the actin cytoskeleton and the plasma membrane and plays a key role in the control of cell morphology, motility, adhesion and other processes of tumourigenesis. The expression pattern and clinical significance of moesin in astrocytoma remain unknown. In this study, we used RT-PCR to systematically investigate the expression of moesin in 49 astrocytomas of different pathological grade and 6 normal brain tissues. We found that the mRNA expression levels of moesin in astrocytomas were significantly higher in comparison with normal brain tissues. Furthermore, moesin up-regulation was correlated with pathological grade of astrocytomas. Subsequently, we tested 112 astrocytomas and 14 normal brain tissues by immunohistochemistry. Similar results were also confirmed. Univariate and multivariate survival analysis were used to determine the correlations of moesin expression with overall survival and progression-free survival. Our results showed the expression of moesin was strongly negatively correlated with the patient progression-free survival and overall survival. These results suggest moesin protein involved in the genesis and progression of astrocytomas and might be regarded as an independent predictor of poor prognosis.

Large medial sphenoid wing meningiomas: long-term outcome and correlation with tumor size after microsurgical treatment in 127 consecutive cases.

AIM: We present the long-term outcomes as well as their correlation with tumor size in 127 consecutive patients harboring large MSWM after microsurgical treatment. MATERIAL AND METHODS: The retrospective analysis of clinical data and follow-up data of 127 microsurgical treated patients with MSWM was performed. The mean maximum diameter of tumors was 5.2cm (ranged 1.5-10.0cm). RESULTS: 104 cases (81.9%) achieved gross total resection. There was no operative mortality. Detailed follow-up data was available in 120 cases for a mean duration of 81.6 months (12-216 months). The permanent morbidity was 14.2%. The mean KPS score 1 year after surgery was 90.6 (ranged 60-100). Among 74 patients of preoperative visual acuity (VA) impairment, postoperative VA improved in 42 cases (56.8%), unchanged in 30 (40.5%), and deteriorated in 2 (2.7%). MR images revealed tumor recurrence after total resection in 10 cases (10.2%) and tumor progression after subtotal resection in 10 cases (45.5%). CONCLUSION: Tumor recurrence was the major risk in the long run, thus the initial surgery was extremely important and hence should be aggressive. The size of tumor affected the extent of tumor removal determining clinical outcomes including VA improvement and KPS score immediately after surgery; however, it was not correlated with long-term overall outcomes.
