Background: Incidence and mortality rates for cancer have increased dramatically in the recent 30 years in Taiwan. However, not all patients receive treatment. Treatment refusal might impair patient survival and life quality. In order to improve this situation, we proposed this study to evaluate factors that are related to refusal of treatment in cancer patients via a cancer case manager system. Materials and Methods: This study analysed data from a case management system during the period from 2010 to 2012 at a medical center in Northern Taiwan. We enrolled a total of 14,974 patients who were diagnosed with cancer. Using the PRECEDE Model as a framework, we conducted logistic regression analysis to identify independent variables that are significantly associated with refusal of therapy in cancer patients. A multivariate logistic regression model was also applied to estimate adjusted the odds ratios (ORs) with 95% confidence intervals (95%CI). Results: A total of 253 patients (1.69%) refused treatment. The multivariate logistic regression result showed that the high risk factors for refusal of treatment in cancer patient included: concerns about adverse effects (p<0.001), poor performance(p<0.001), changes in medical condition (p<0.001), timing of case manager contact (p=.026), the methods by which case manager contact patients (p<0.001) and the frequency that case managers contact patients (${\geq}10times$) (p=0.016). Conclusions: Cancer patients who refuse treatment have poor survival. The present study provides evidence of factors that are related to refusal of therapy and might be helpful for further application and improvement of cancer care.

Purpose The evidence of adherence to cancer prevention guidelines and endometrial cancer (EC) risk has been limited and controversial. This study summarizes and quantifies the relationship between adherence to cancer prevention guidelines and EC risk. Materials and Methods The online databases PubMed, Web of Science, and EMBASE were searched for relevant publications up to June 2, 2020. This study had been registered at PROSPERO. The registration number is CRD42020149966. Study quality evaluation was performed based on the Newcastle-Ottawa Scale. The I2 statistic was used to estimate heterogeneity among studies. Egger’s and Begg’s tests assessed potential publication bias. Summary hazard ratios (HRs) and 95% confi dence intervals (CIs) for the relationship between adherence to cancer prevention guidelines score was assigned to participants by summarizing individual scores for each lifestyle-related factor. The scores ranged from least healthy (0) to most healthy (20) and the EC risk was calculated using a random-effects model. Results Five prospective studies (four cohort studies and one case‑cohort study) consisted of 4,470 EC cases, where 597,047 participants were included. Four studies had a low bias risk and one study had a high bias risk. Summary EC HR for the highest vs. lowest score of adherence to cancer prevention guidelines was 0.54 (95% CI, 0.40 to 0.73) and had a high heterogeneity (I2=86.1%). For the dose-response analysis, an increment of 1 significantly reduced the risk of EC by 6%. No signifi cant publication bias was detected. Conclusion This study suggested that adherence to cancer prevention guidelines was negatively related to EC risk.

Comprehensive consideration regarding influence mechanisms of initial imperfections on ultimate strength of spherical shells is taken to satisfy requirement of deep-sea structural design. The feasibility of innovative numerical procedure that combines welding simulation and nonlinear buckling analysis is verified by a good agreement to experimental and theoretical results. Spherical shells with a series of wall thicknesses to radius ratios are studied. Residual stress and deformations from welding process are investigated separately. Variant influence mechanisms are discovered. Residual stress is demonstrated to be influential to stress field and buckling behavior but not to the ultimate strength. Deformations are proved to have a significant impact on ultimate strength. When central angles are less than critical value, concave magnitudes reduce ultimate strengths linearly. However, deformations with central angles above critical value are of much greater harm. Less imperfection susceptibility is found in spherical shells with larger wall thicknesses to radius ratios.

Interleukin (IL)-20, a proinflammatory cytokine of the IL-10 family, is involved in acute and chronic renal failure. The aim of this study was to elucidate the role of IL-20 during diabetic nephropathy development. We found that IL-20 and its receptor IL-20R1 were upregulated in the kidneys of mice and rats with STZ-induced diabetes. In vitro, IL-20 induced MMP-9, MCP-1, TGF-β1 and VEGF expression in podocytes. IL-20 was upregulated by hydrogen peroxide, high-dose glucose and TGF-β1. In addition, IL-20 induced apoptosis in podocytes by activating caspase-8. In STZ-induced early diabetic nephropathy, IL-20R1-deficient mice had lower blood glucose and serum BUN levels and a smaller glomerular area than did wild-type controls. Anti-IL-20 monoclonal antibody (7E) treatment reduced blood glucose and the glomerular area and improved renal functions in mice in the early stage of STZ-induced diabetic nephropathy. ELISA showed that the serum IL-20 level was higher in patients with diabetes mellitus than in healthy controls. The findings of this study suggest that IL-20 induces cell apoptosis of podocytes and plays a role in the pathogenesis of early diabetic nephropathy.

ZnO nanorods were grown on glass substrates coated by an Al-doped ZnO seed layer via a simple solvothermal method using zinc acetate dihydrate (Zn(CH3COO)2 • 2H2O) and Hexamethylenetetramine (C6H12N4) reagent. The structure, morphology and optical properties of these ZnO nanorods dependence on the molar ratio of Zn(CH3COO)2 • 2H2O to C6H12N4 were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Ultraviolet and Visible Spectrophotometry (UV-vis) and photoluminescence (PL) spectrometry, respectively. The XRD patterns indicated that all the ZnO nanorods were well-faceted hexagonal structures and preferentially grown along the c-axis. As the molar ratio of Zn(CH3COO)2 • 2H2O to C6H12N4 decreasing from 2.5 to 0.25, the crystallinity of ZnO nanorods synthesized gradually became inferior and the width of ZnO nanorods also decreased. The blue-shifts of UV emission excited from ZnO nanorods probably arised from the decreased size of ZnO nanorods.

Fenton-like catalysts have sparked enormous interest from academic to industrial fields because of theirexcellent degradability and offered a promising platform for the effective treatment of wastewater. However, it remains a grand challenge to balance their catalytic performance and corrosion resistancefor industrial application. To address this issue, we report Cr and C dual-doped photo-enhancedFenton-like catalysts (Cr, C-FeSiB) in which Cr functions as a corrosion inhibitor to improve recycling performanceand C acts as an electron transfer accelerator to raise the cycle efficiency of iron ions duringcomplex Fenton-like reactions. Moreover, we design a low energy-consumption magnetic-suspensionlikereactor in which Fenton-like catalysts can work as micro-scaled stirrers to enhance the mass transferefficiency during the Fenton-like reactions owing to their soft magnetic property.

Two novel coordination polymers (where Cu for the complex 1 and the Co for the complex 2) with distinct transition metal ions containing 4-(3,5-dicarboxylphenyl)-2- methylpyridine (H2L), the pyridyl-dicarboxylic acid ligand, have been produced under the solvothermal reaction conditions, and the two compounds’ performances and architectures were also characterized. The chemical formulae determined of two complexes are respectively [Cu(L)(H2O)]·H2O (1) and [Co3(L)2Cl2(H2O)2]·2H2O (2). Complex 1 exhibits a 2D network with a (3,6)-connected kgd topology based on the dinuclear [Cu2O2] units. In complex 2, the linear trinuclear [Co3(μ-Ocarboxylate)2(COO)2Cl2] units with mixed carboxylate and μ-Cl triple bridges are cross-linked by the L ligands into a 3D framework with a (3,6)-connected rtl topology. The complexes’ magnetic performances reflected that between consecutive metal ions, there exists the antiferromagnetic coupling. Their treatment activities on Alzheimer's disease (AD) via focused high-intensity ultrasound were evaluated. Firstly, the Annexin V-fluorescein isothiocyanate/propidium iodide staining was implemented for the assessment of the apoptotic neurons percentage after compounds treatment. Next, the Aβ accumulation in the neurons was also detected via employing the western blotting assay.
