The Long-Term Effects of Bariatric Surgery on Type 2 Diabetes Remission, Microvascular and Macrovascular Complications, and Mortality: a Systematic Review and Meta-Analysis.
This systematic review aimed to evaluate the long-term (≥ 5 years) outcomes of bariatric surgery on diabetes remission, microvascular and macrovascular events, and mortality among type 2 diabetes (T2D) patients. Ten articles (one randomized controlled trial and nine cohorts) met the inclusion criteria and were included in this review. Pooled estimates of nine cohort studies showed that surgery significantly increased the diabetes remission (relative risk (RR) = 5.90; 95% CI 3.75-9.28), reduced the microvascular (RR = 0.37; 95% CI = 0.30-0.46) and macrovascular events (RR = 0.52; 95% CI 0.44-0.61), and mortality (RR = 0.21; 95% CI 0.20-0.21) as compared to non-surgical treatment. Available evidence suggests better remission and lower risks of microvascular and macrovascular disease and mortality in the surgery group as compared to non-surgical treatment group in T2D patients after at least 5 years of follow-up
Prediction and analysis of ultimate bearing capacity of square CFST long column under eccentric compression after acid rain corrosion
This paper adopts the method of steel tube wall thickness and strength reduction to simulate corrosion damage. The numerical model of the square concrete-filled steel tube long column (SCFST-LC) under eccentric compression after acid rain corrosion is established in the finite element software, ABAQUS. The reliability and accuracy of the model are verified by comparing it with published relevant experimental results. The failure mode, load-deformation curve, and ultimate compressive load were analysed. Following that, the impacts of section size, yield strength of the steel tube, axial compressive strength of concrete, steel ratio, slenderness ratio, and load eccentricity on its ultimate compressive load are comprehensively investigated. The results demonstrate that the ultimate compressive load of the SCFST-LC decreases significantly with the increase in corrosion rate. The corrosion rate increases from 10 to 40%, and the ultimate bearing capacity decreases by 37.6%. Its ultimate bearing capacity can be enhanced due to the increase in section size, material strength, and steel ratio. In contrast, the ascending slenderness ratio and load eccentricity has harmful effects on the ultimate compressive load of the specimens. Finally, a simplified formula for the axial compressive load of the SCFST-LC under eccentric compression after acid rain corrosion is proposed. The calculation accuracy is high and the deviation of the results is basically within 15%, which is in good agreement with the numerical simulation results

Abstract Decomposing Polygon Meshes for Interactive Applications
This paper discusses an efficient and effective framework to decompose polygon meshes into components. This is useful in various interactive graphics applications, such as, mesh editing, establishing correspondence between objects for morphing, computation of bounding volume hierarchy for collision detection and ray tracing. In this paper, we formalize the notion of a component as a sub-volume of an object with homogeneous geometric and topological features. Next, we describe the proposed framework, which adapts the idea of edge contraction and space sweeping to decompose an object automatically. Finally, we demonstrate an application of this framework to improve bounding volume hierarchies constructed by state-of-theart collision detection systems such as RAPID and QuickCD
Essential Public Health Services' Accessibility and its Determinants among Adults with Chronic Diseases in China.
Along with three years implementation of health reform in China, this study aimed at providing the up-to-date evidence about the accessibility of essential public health services (EPHS) among adults with chronic diseases (CDs) in both urban and rural areas, as well as determinants in access to EPHS.The data were collected from a cross-sectional survey conducted in 2013, which used a multistage stratified random sampling method to select 54 urban communities and 54 rural villages. Hypertension patients and diabetes patients were the target population who are the main beneficiaries of EPHS. Single factor analysis of influencing factors on difference access to EPHS was performed by Chi-Square analysis. Logistic regression analysis was used to determine the predictors of effective management and effective control.Patients with hypertension or diabetes were predominantly middle-aged or older persons and had a mean age of 65.26 year. People with CDs in China have a higher basic accessibility rate in EPHS with more than 90% of them having experience in receiving EPHS. And those who are willing to receive services from doctors have the most positive influence on effective management and control in blood pressure or blood glucose. But unsatisfied quality and equity of EPHS still exist in primary health system. 90% of participants could receive EPHS, but just 44% of them could control their diseases effectively. And participants from cities had the higher rates in effective management (urban: rural = 57%: 50.6%) and effective control (urban: rural = 39.5%: 27.8%).People with CDs have a high level in geography and economic accessibility to EPHS, but the effectiveness of health management also needs to be improved, especially for those living in rural areas. Our study highlights the continuing need for improving ability to provide EPHS and the equality among regions. Meanwhile, strengthen health education and promotion for patients with CDs to improve their willingness to receive EPHS is also highlighted
